CSCS Health, Safety and Environment Test — Questions and Answers

Question 1: What is the HSE's MAC (Manual Handling Assessment Charts) tool?

A risk assessment tool that uses a colour-coded system to evaluate lifting, carrying, and team handling tasks (Correct answer)
A type of lifting equipment
A map of manual handling areas
A medical assessment certificate

Correct answer: A risk assessment tool that uses a colour-coded system to evaluate lifting, carrying, and team handling tasks

The MAC tool is a free HSE risk assessment tool that uses colour-coded bands (green, amber, red, purple) to help assessors evaluate the risk level of lifting, carrying, and team handling operations and prioritise improvements.

Question 2: What is the significance of the IP rating 'IP65' on a construction site distribution board?

It refers to the maximum amperage the board can handle
It means the enclosure is dust-tight (6) and protected against water jets (5) from any direction, making it suitable for harsh outdoor construction environments (Correct answer)
It indicates the board can only be used indoors
IP65 is a fire resistance rating

Correct answer: It means the enclosure is dust-tight (6) and protected against water jets (5) from any direction, making it suitable for harsh outdoor construction environments

The IP (Ingress Protection) rating system defined in BS EN 60529 uses two digits: the first (6) indicates complete protection against dust ingress, and the second (5) indicates protection against water jets from any direction. IP65 is suitable for outdoor construction site use where boards are exposed to dust, rain, and wash-down. BS 7671 requires equipment to be suitable for its environment.

Question 3: What must be done with temporary heaters on a construction site to prevent fire?

Leave them running overnight to prevent frost damage
Place them near doorways for convenience
Use only approved heaters, keep them away from combustible materials, never leave unattended, and ensure adequate ventilation (Correct answer)
No precautions are needed for electric heaters

Correct answer: Use only approved heaters, keep them away from combustible materials, never leave unattended, and ensure adequate ventilation

Temporary heaters must be approved for site use, positioned away from combustible materials with adequate clearance, never left unattended or overnight, and used with adequate ventilation (especially LPG heaters which produce carbon monoxide).

Question 4: What is the role of the Health and Safety Executive (HSE) in relation to licensed asbestos removal contractors?

The HSE only investigates after someone becomes ill
The HSE delegates all asbestos matters to local councils
The HSE has no involvement with asbestos removal
The HSE issues licences to asbestos removal contractors, receives notifications of work (ASB5 forms), inspects work in progress, investigates complaints and incidents, and can revoke licences for non-compliance (Correct answer)

Correct answer: The HSE issues licences to asbestos removal contractors, receives notifications of work (ASB5 forms), inspects work in progress, investigates complaints and incidents, and can revoke licences for non-compliance

The HSE is the primary regulator for licensed asbestos work. It assesses applications and issues licences (typically for 3 years), receives ASB5 notifications before work begins, conducts announced and unannounced site inspections, investigates complaints and reportable incidents, and can suspend or revoke licences if standards are not met. The licensing regime is a cornerstone of asbestos safety in the UK.

Question 5: What should be done with an electrical tool that has failed its PAT test on a construction site?

It must be immediately withdrawn from service, labelled as defective, and either repaired by a competent person and retested, or disposed of (Correct answer)
It can be used if supervised by a qualified electrician
It should be returned to the manufacturer only
It can still be used until a replacement arrives

Correct answer: It must be immediately withdrawn from service, labelled as defective, and either repaired by a competent person and retested, or disposed of

Equipment that fails a PAT test must be immediately removed from service and clearly labelled or tagged as defective to prevent anyone else using it. Under the Electricity at Work Regulations 1989 and PUWER 1998, it must then be repaired by a competent person and pass a retest before being returned to service, or be disposed of.

Question 6: What is the purpose of a Genny (signal generator) used in conjunction with a CAT scanner before excavation?

To communicate with workers in the trench
To test the soil composition
To apply a detectable signal to specific underground services so the CAT can locate non-metallic and dead cables that would otherwise be undetectable (Correct answer)
To generate electricity for site lighting

Correct answer: To apply a detectable signal to specific underground services so the CAT can locate non-metallic and dead cables that would otherwise be undetectable

A Genny (signal generator) connects to or induces a signal onto specific underground services, allowing the CAT to detect cables and pipes that do not naturally emit a detectable signal. This includes dead electrical cables, fibre optic cables, and plastic pipes. HSE guidance HSG47 requires both CAT and Genny to be used together for a thorough survey.

Question 7: What does RAMS stand for in UK construction?

Regulatory And Management Standards
Risk Assessments and Method Statements (Correct answer)
Risk Assessment Management System
Resource Allocation and Management Schedule

Correct answer: Risk Assessments and Method Statements

RAMS stands for Risk Assessments and Method Statements. These are the two key documents used together on UK construction sites to identify hazards, assess risks, and describe how work will be carried out safely. RAMS are typically required before any work begins on site.

Question 8: How often must portable electrical equipment on a construction site undergo PAT testing as a general guideline?

Every 12 months
Every 3 months (Correct answer)
Only when visibly damaged
Every 6 months

Correct answer: Every 3 months

HSE and IET guidance recommend that portable appliances on construction sites are formally PAT tested every 3 months due to the harsh working environment. Additionally, users should carry out visual checks before each use. The frequency is more stringent than for office environments due to the higher risk of damage.

Question 9: What should you do if you discover a fire on a construction site?

Try to fight it immediately
Take a photo for evidence
Continue working until told to evacuate
Raise the alarm, call the fire brigade (999), evacuate to the assembly point, and only fight the fire if trained and it is safe to do so (Correct answer)

Correct answer: Raise the alarm, call the fire brigade (999), evacuate to the assembly point, and only fight the fire if trained and it is safe to do so

The priority sequence is: raise the alarm (activate the nearest break glass point), call 999, evacuate via the nearest safe route to the assembly point. Only attempt to fight a small fire if you are trained and it is safe to do so.

Question 10: How does the HSE recommend reducing the risk from pushing and pulling operations?

Reduce the force required, improve floor surfaces, use mechanical aids, and maintain equipment wheels (Correct answer)
Use more force
Only allow strong workers to push loads
Push harder and faster

Correct answer: Reduce the force required, improve floor surfaces, use mechanical aids, and maintain equipment wheels

HSE recommends reducing push/pull forces by using well-maintained trolleys with good wheels, ensuring smooth floor surfaces, eliminating slopes where possible, and keeping loads at a manageable height for the worker.

Question 11: What standard must safety spectacles meet for use on UK construction sites?

Any optical standard
BS EN 166 or its replacement BS EN ISO 16321 (Correct answer)
ISO 9001
BS 7671

Correct answer: BS EN 166 or its replacement BS EN ISO 16321

Safety spectacles for construction use must meet BS EN 166 (Personal eye protection — Specifications) or its successor BS EN ISO 16321. They must be marked with the relevant impact grade and optical class.

Question 12: What must an employer do if their first aid needs assessment identifies that workers are at risk from specific hazards such as hydrofluoric acid?

Provide standard first aid kits only
Only inform workers of the risk verbally
Provide additional specialist first aid equipment and training relevant to those specific hazards (Correct answer)
Rely on the emergency services for all specialist treatment

Correct answer: Provide additional specialist first aid equipment and training relevant to those specific hazards

Where a risk assessment identifies specific hazards such as chemical exposure, the employer must provide additional first aid equipment and ensure first aiders receive specific training for those hazards. For example, calcium gluconate gel may be needed for hydrofluoric acid burns.

Question 13: If male and female workers must share sanitary conveniences on a construction site, what must be in place?

A timetable showing when each group may use the facilities
Separate queuing systems outside the toilet block
The facilities must be lockable from the inside and used by one person at a time (Correct answer)
No special arrangement is needed on small sites

Correct answer: The facilities must be lockable from the inside and used by one person at a time

Where separate facilities for men and women cannot be provided, CDM 2015 allows shared use only if the facility is lockable from the inside and used by one person at a time.

Question 14: What training and competency requirements apply to operatives using a CAT and Genny for underground service detection?

Operatives must be trained and assessed as competent in the use of CAT and Genny equipment, with refresher training typically every 3 years, as recommended by PAS 128 and HSE guidance (Correct answer)
No specific training is required — the devices are self-explanatory
Only a 10-minute toolbox talk is required
Training is only required for supervisors, not operators

Correct answer: Operatives must be trained and assessed as competent in the use of CAT and Genny equipment, with refresher training typically every 3 years, as recommended by PAS 128 and HSE guidance

HSE guidance HSG47 and the PAS 128 specification require that operatives using CAT and Genny equipment receive formal training covering the principles of operation, correct use of all modes, interpretation of results, and limitations of the equipment. Competency must be assessed and refresher training provided typically every 3 years. Records of training must be maintained.

Question 15: Which of the following is the correct hierarchy for managing risks when working at height?

Mitigate, prevent, avoid
Use PPE first, then collective protection, then avoid
Avoid, prevent, mitigate (Correct answer)
Prevent, avoid, use PPE

Correct answer: Avoid, prevent, mitigate

The hierarchy under the Work at Height Regulations 2005 is: first avoid work at height, then prevent falls using collective or personal protection, then mitigate the distance and consequences of a fall.

Question 16: What is the primary purpose of a Residual Current Device (RCD) on a construction site?

To detect earth leakage current and disconnect the supply rapidly (Correct answer)
To monitor energy consumption
To prevent overloading of circuits
To regulate voltage fluctuations

Correct answer: To detect earth leakage current and disconnect the supply rapidly

An RCD detects an imbalance between live and neutral conductors caused by earth leakage current and disconnects the supply within milliseconds. Under the Electricity at Work Regulations 1989, RCDs provide additional protection against electric shock but are not a substitute for reduced voltage systems.

Question 17: What is the maximum permitted loading on a scaffold as stated on the scaffold loading notice?

There is no maximum if the scaffold looks sturdy
The load specified by the scaffold designer and shown on the loading notice (Correct answer)
500kg per bay in all cases
Whatever the erector decides

Correct answer: The load specified by the scaffold designer and shown on the loading notice

Every scaffold must have a loading notice displayed prominently, specifying the maximum permitted load as determined by the scaffold designer. Overloading is a common cause of scaffold collapse.

Question 18: Where should AED pads be placed on a casualty?

One below the right collarbone and one on the lower left side of the chest (Correct answer)
Both pads on the stomach
Both pads on the left side of the chest
One on each arm

Correct answer: One below the right collarbone and one on the lower left side of the chest

AED pads should be placed with one pad below the right collarbone and the other on the lower left side of the chest, under the armpit. This positioning allows the electrical current to pass through the heart. Most AED pads have diagrams showing correct placement.

Question 19: What does the term 'RPE' stand for on a construction site?

Respiratory Protective Equipment (Correct answer)
Registered Professional Engineer
Risk Prevention Equipment
Required Personal Equipment

Correct answer: Respiratory Protective Equipment

RPE stands for Respiratory Protective Equipment, which includes disposable masks, half-face and full-face respirators, powered air-purifying respirators (PAPRs), and self-contained breathing apparatus (SCBA).

Question 20: What is the primary purpose of installing trench boxes during excavation work on a construction site?

To store tools and materials underground
To prevent the collapse of trench sides and protect operatives working within the excavation (Correct answer)
To channel rainwater away from the trench
To mark the boundaries of the excavation for surveying

Correct answer: To prevent the collapse of trench sides and protect operatives working within the excavation

Trench boxes (also called trench shields) are structural supports placed inside excavations to prevent the sides from collapsing onto workers. Under the CDM Regulations 2015 and the Work at Height Regulations 2005 (which also cover work below ground), adequate support must be provided to prevent collapse in any excavation where there is a risk.

Question 21: Which of the following activities on a construction site would typically require a COSHH assessment?

Using a tape measure
Carrying timber by hand
Walking across level ground
Mixing cement or cutting concrete blocks (Correct answer)

Correct answer: Mixing cement or cutting concrete blocks

Mixing cement exposes workers to cement dust (containing hexavalent chromium, a skin sensitiser) and wet cement (alkaline, causes burns). Cutting concrete generates respirable crystalline silica dust. Both activities require a COSHH assessment to identify hazards and implement controls such as LEV, water suppression, and appropriate PPE.

Question 22: What method should be used for backfilling an excavation that runs adjacent to an existing building foundation?

The excavation can be left open indefinitely if it is fenced
Backfilling is not required if the excavation is shallow
Rapid backfilling with any available material using heavy plant
Controlled backfilling in compacted layers using approved granular material to avoid settlement or damage to the adjacent foundation (Correct answer)

Correct answer: Controlled backfilling in compacted layers using approved granular material to avoid settlement or damage to the adjacent foundation

Backfilling near existing foundations must be carried out carefully in compacted layers (typically 150-300mm) using suitable granular material to prevent future settlement. Uncontrolled backfilling can cause ground movement affecting adjacent structures. The method must be specified in the method statement under CDM Regulations 2015, and a structural engineer may need to approve the approach.

Question 23: What is an Assigned Protection Factor (APF) in relation to RPE?

A number indicating the level of protection the RPE provides when properly fitted and worn (Correct answer)
The weight of the RPE
The cost of the RPE
The colour code of the filter

Correct answer: A number indicating the level of protection the RPE provides when properly fitted and worn

The Assigned Protection Factor (APF) indicates the level of respiratory protection a particular type of RPE will provide when properly fitted and worn. For example, an APF of 20 means the RPE reduces exposure by a factor of 20.

Question 24: What is the difference between an 'appointed person' and a 'first aider' under UK health and safety regulations?

A first aider is only responsible for calling the emergency services
There is no difference; the terms are interchangeable
An appointed person takes charge of first aid arrangements but is not required to hold a first aid certificate (Correct answer)
An appointed person holds an advanced trauma certificate

Correct answer: An appointed person takes charge of first aid arrangements but is not required to hold a first aid certificate

Under the Health and Safety (First-Aid) Regulations 1981, an appointed person takes charge of first aid arrangements and calls the emergency services when needed, but does not need a first aid qualification. A first aider must hold a valid certificate from an HSE-approved training provider.

Question 25: What is the legal requirement for asbestos awareness training for construction workers under the Control of Asbestos Regulations 2012?

Training is optional and at the employer's discretion
Training is only required for asbestos removal operatives
All workers whose work could foreseeably disturb asbestos must receive asbestos awareness training before starting such work, including information on properties of asbestos, health effects, likely locations, and emergency procedures (Correct answer)
Training is only required for workers over 25 years of age

Correct answer: All workers whose work could foreseeably disturb asbestos must receive asbestos awareness training before starting such work, including information on properties of asbestos, health effects, likely locations, and emergency procedures

Regulation 10 of the Control of Asbestos Regulations 2012 requires that all employees whose work could foreseeably expose them to asbestos receive adequate asbestos awareness training. This includes construction workers, maintenance staff, electricians, plumbers, and any tradesperson working in buildings that may contain asbestos. Training must be repeated at regular intervals.

Question 26: What are the key elements of a good site induction under CDM 2015?

Site-specific hazards, emergency procedures, first aid arrangements, welfare locations, site rules, reporting procedures, and worker responsibilities (Correct answer)
Only the location of the car park
Just a quick walk around the site
A written test on construction regulations

Correct answer: Site-specific hazards, emergency procedures, first aid arrangements, welfare locations, site rules, reporting procedures, and worker responsibilities

A comprehensive site induction should cover: site-specific hazards and ongoing risks, emergency procedures and muster points, first aid provisions and locations, welfare facility locations, site rules and prohibited areas, PPE requirements, reporting procedures for accidents and near-misses, and workers' legal responsibilities.

Question 27: What is the purpose of a risk assessment on a construction site?

To identify hazards, evaluate the risks, and determine appropriate control measures to protect workers and others (Correct answer)
To calculate the insurance premium for the project
To measure the dimensions of the site
To list all the equipment needed for the project

Correct answer: To identify hazards, evaluate the risks, and determine appropriate control measures to protect workers and others

Under the Management of Health and Safety at Work Regulations 1999 Regulation 3, employers must carry out a suitable and sufficient assessment of the risks to which workers and others are exposed. The assessment identifies hazards, evaluates who might be harmed and how, and determines what control measures are needed.

Question 28: Under COSHH, for how long must employers keep health surveillance records?

10 years
40 years from the date of the last entry (Correct answer)
Indefinitely
5 years

Correct answer: 40 years from the date of the last entry

Under COSHH Regulation 11, health surveillance records must be kept for at least 40 years from the date of the last entry. This lengthy retention period reflects the fact that many occupational diseases, such as mesothelioma, may not manifest for decades after exposure.

Question 29: What is the purpose of Local Exhaust Ventilation (LEV) under COSHH?

To circulate fresh air throughout the entire building
To monitor air quality in real time
To heat the workplace during cold weather
To capture airborne contaminants at the source before they enter the worker's breathing zone (Correct answer)

Correct answer: To capture airborne contaminants at the source before they enter the worker's breathing zone

LEV systems capture dust, fumes, vapours, and other airborne contaminants at or near the point of generation, preventing them from entering the worker's breathing zone. Under COSHH, LEV must be properly designed, maintained, and tested at least every 14 months.

Question 30: What must an employer do if a worker is diagnosed with HAVS or carpal tunnel syndrome related to vibration at work?

Only record the diagnosis in the accident book
Nothing; it is the worker's personal health issue
Simply provide anti-vibration gloves
Review the risk assessment, consider removing the worker from vibration-exposed work, and ensure all other exposed workers are under health surveillance (Correct answer)

Correct answer: Review the risk assessment, consider removing the worker from vibration-exposed work, and ensure all other exposed workers are under health surveillance

If a worker is diagnosed with HAVS or carpal tunnel syndrome linked to vibration exposure, the employer must review and revise the risk assessment, consider whether the affected worker should be redeployed to work without vibration exposure, ensure health surveillance covers all other at-risk workers, and consider reporting under RIDDOR.

Question 31: What class of electrical equipment relies solely on double insulation for protection rather than an earth connection?

Class 0
Class III
Class I
Class II (Correct answer)

Correct answer: Class II

Class II equipment (marked with the double square symbol) relies on double or reinforced insulation for protection against electric shock and does not require an earth connection. The Electricity at Work Regulations 1989 recognise double insulation as a valid protective measure. Class I equipment relies on an earth connection, while Class III uses Safety Extra-Low Voltage (SELV).

Question 32: How often must asbestos-containing materials that are being managed in situ (left in place) be re-inspected?

They never need re-inspection once identified
At regular intervals as determined by the management plan — typically at least annually, and more frequently if the ACM is in a location where it may be disturbed (Correct answer)
Only when a complaint is received
Every 10 years is sufficient

Correct answer: At regular intervals as determined by the management plan — typically at least annually, and more frequently if the ACM is in a location where it may be disturbed

ACMs managed in situ must be regularly re-inspected to check their condition has not deteriorated. The frequency depends on the material type, condition, and likelihood of disturbance, but is typically at least annually. High-risk materials in busy areas may require more frequent checks. This is a requirement of the duty to manage under Regulation 4 of the Control of Asbestos Regulations 2012.

Question 33: What does WBV stand for in relation to vibration at work?

Workplace Building Ventilation
Whole Body Vibration (Correct answer)
Work Based Verification
Weekly Baseline Value

Correct answer: Whole Body Vibration

WBV stands for Whole Body Vibration, which is transmitted through the seat or feet of workers operating mobile plant and machinery such as dumpers, excavators, and forklift trucks. Prolonged WBV exposure can cause lower back pain and spinal disorders.

Question 34: What type of access and egress must be provided for excavations deeper than 1.2 metres?

A secured ladder or other safe means of access/egress must be provided within the excavation, positioned so no operative has to travel more than 25 metres to reach it (Correct answer)
Operatives can climb the shoring framework
No specific access provisions are required if the excavation is less than 2 metres deep
Ropes are sufficient for access and egress

Correct answer: A secured ladder or other safe means of access/egress must be provided within the excavation, positioned so no operative has to travel more than 25 metres to reach it

HSE guidance requires that for excavations deeper than 1.2 metres, suitable and sufficient means of access and egress must be provided, typically secured ladders extending at least 1 metre above the excavation edge. Ladders should be positioned so that no worker has to travel more than 25 metres along the trench to reach one. Under CDM 2015, these provisions must be planned.

Question 35: What is the purpose of a near-miss reporting system on a construction site?

To increase paperwork for the site manager
To discipline workers who make mistakes
To identify and address hazards before they cause actual harm, and to improve safety management systems through trend analysis (Correct answer)
To report near-misses to the police

Correct answer: To identify and address hazards before they cause actual harm, and to improve safety management systems through trend analysis

Near-miss reporting allows hazards to be identified and addressed before they result in injury or damage. Analysis of near-miss trends can reveal systemic safety issues. A culture of open reporting without blame encourages workers to report all near-misses, providing valuable data for proactive safety improvement.

Question 36: What must a construction site manager check about a waste carrier before allowing them to remove waste from site?

Nothing — any vehicle can transport construction waste
Only that the driver has a valid driving licence
The carrier must hold a valid waste carrier registration issued by the Environment Agency, have appropriate vehicle insurance, and provide a correctly completed Waste Transfer Note — the registration can be verified on the Environment Agency's public register (Correct answer)
Only that the vehicle is roadworthy

Correct answer: The carrier must hold a valid waste carrier registration issued by the Environment Agency, have appropriate vehicle insurance, and provide a correctly completed Waste Transfer Note — the registration can be verified on the Environment Agency's public register

Under the Environmental Protection Act 1990 and the Controlled Waste (Registration of Carriers and Seizure of Vehicles) Regulations 1991, anyone transporting controlled waste must be registered with the Environment Agency. The site manager must verify the carrier's registration (checkable online on the EA public register), ensure a complete Waste Transfer Note is produced, and confirm the waste is going to an appropriately permitted facility. Using an unregistered carrier is an offence.

Question 37: What should a first aider do if they suspect a worker has heat stroke on site?

Tell them to continue working in the shade
Apply a tourniquet to reduce blood flow
Give them hot drinks to replace fluids
Move them to a cool area, remove outer clothing, and cool them with water while calling 999 (Correct answer)

Correct answer: Move them to a cool area, remove outer clothing, and cool them with water while calling 999

Heat stroke is a medical emergency. The worker should be moved to a cool area, outer clothing removed, and their body cooled using water, wet towels, or fanning. Call 999 immediately. Do not give them anything to drink if they are confused or unconscious.

Question 38: What information must an employer provide to employees about loads they handle?

Only the delivery address
The weight of the load, its centre of gravity, and the heaviest side (Correct answer)
No information is required
The cost of the load

Correct answer: The weight of the load, its centre of gravity, and the heaviest side

Under the Manual Handling Operations Regulations 1992, employers must provide information about the weight of loads, the location of the centre of gravity (especially if offset), and the heaviest side of an uneven load.

Question 39: A worker using a breaker has a vibration exposure of 12 m/s². What is the maximum continuous exposure time to stay within the EAV of 2.5 m/s²?

About 30 minutes (Correct answer)
About 15 minutes
About 2 hours
About 1 hour

Correct answer: About 30 minutes

The HSE Ready Reckoner shows that for a tool with a vibration magnitude of 12 m/s², the exposure time to reach the EAV of 2.5 m/s² A(8) is approximately 30 minutes. Workers must stop using the tool at this point or their exposure will exceed the action value, triggering additional employer duties.

Question 40: What is the correct procedure before carrying out electrical isolation of equipment on a construction site?

Ask a colleague to hold the switch in the off position
Simply unplug the equipment and begin work
Switch off, isolate, lock off, prove dead using a voltage tester, and attach warning notices (Correct answer)
Turn off the main supply to the entire site

Correct answer: Switch off, isolate, lock off, prove dead using a voltage tester, and attach warning notices

Safe isolation follows a strict sequence: switch off, isolate from all sources, lock off with a personal padlock, prove dead using a GS38-compliant voltage tester (tested before and after on a known live source), and attach warning notices. This procedure is mandated under the Electricity at Work Regulations 1989.

Question 41: What is a Workplace Exposure Limit (WEL)?

The maximum amount of PPE a worker must wear
The maximum number of hours a worker can be exposed to any substance
The legal maximum concentration of a hazardous substance in workplace air, averaged over a reference period (Correct answer)
The limit on the number of hazardous substances allowed on site

Correct answer: The legal maximum concentration of a hazardous substance in workplace air, averaged over a reference period

A Workplace Exposure Limit (WEL) is the maximum concentration of an airborne substance, averaged over a specified reference period (typically 8 hours TWA or 15-minute STEL), to which workers may be exposed. WELs are listed in HSE publication EH40.

Question 42: What is the emergency services telephone number in the UK?

911
111
000
112 or 999 (Correct answer)

Correct answer: 112 or 999

In the UK, the emergency services can be reached by dialling 999 or 112. Both numbers connect to the same emergency services. 112 is the European standard emergency number and also works on mobile phones even without a SIM card or network coverage.

Question 43: What is the legal framework for controlling vibration from construction activities that affects neighbouring properties?

There is no legal control over construction vibration
Vibration is controlled under the Environmental Protection Act 1990 (statutory nuisance), BS 5228-2 (Code of practice for noise and vibration control on construction sites), and planning conditions — vibration limits at sensitive receptors must be monitored and complaints investigated (Correct answer)
Only piling work is subject to vibration controls
Vibration is only controlled if it causes structural damage

Correct answer: Vibration is controlled under the Environmental Protection Act 1990 (statutory nuisance), BS 5228-2 (Code of practice for noise and vibration control on construction sites), and planning conditions — vibration limits at sensitive receptors must be monitored and complaints investigated

Construction vibration is controlled by: the Environmental Protection Act 1990 (vibration can constitute a statutory nuisance); BS 5228-2:2009+A1:2014 (provides guidance on vibration prediction, measurement, and control); planning conditions (often set vibration limits at sensitive receptors); and the Party Wall etc. Act 1996 (for work affecting adjoining properties). Continuous vibration monitoring at nearby properties is often required, with trigger and stop limits.

Question 44: Under CDM 2015, what is the principal contractor's duty regarding consultation with workers?

Only consult with trade union officials
Only consult with the client
The principal contractor must engage with workers and their representatives on matters affecting their health, safety, and welfare (Correct answer)
No consultation is required

Correct answer: The principal contractor must engage with workers and their representatives on matters affecting their health, safety, and welfare

Under CDM 2015 Regulation 14(d), the principal contractor must consult and engage with workers, including the workforce and their representatives, on matters connected with the project that may affect their health, safety, or welfare. This can be achieved through toolbox talks, safety committees, and worker forums.

Question 45: What is the trigger point for health surveillance for workers exposed to hand-arm vibration?

Only when a worker reports symptoms
Regular exposure at or above the exposure action value of 2.5 m/s² A(8), or where there is a risk of HAVS for any other reason (Correct answer)
Any use of vibrating tools regardless of exposure level
Only for workers over 40 years old

Correct answer: Regular exposure at or above the exposure action value of 2.5 m/s² A(8), or where there is a risk of HAVS for any other reason

Health surveillance must be provided for workers regularly exposed at or above the HAV exposure action value of 2.5 m/s² A(8), or where there is a risk of HAVS for any other reason (for example, workers with pre-existing conditions). Surveillance includes questionnaires, clinical assessments, and standardised testing.

Question 46: What is the purpose of the 'C' in DR ABC?

To call for a colleague
To check the casualty's consciousness
To check for circulation and control catastrophic bleeding (Correct answer)
To commence CPR

Correct answer: To check for circulation and control catastrophic bleeding

In DR ABC, C stands for Circulation. At this stage you check for signs of circulation and control any catastrophic or severe bleeding. In the updated <C>ABC approach, the initial C for Catastrophic bleeding is addressed even before the airway.

Question 47: What action should be taken if a harness has been involved in arresting a fall?

Clean it and return it to service
Return it to the manufacturer for a refund
Remove it from service immediately and have it inspected by a competent person (Correct answer)
Check the stitching and reuse if it looks undamaged

Correct answer: Remove it from service immediately and have it inspected by a competent person

A harness that has arrested a fall must be immediately removed from service. The forces involved in a fall arrest can cause internal damage to webbing and stitching that may not be visible. It must be inspected by a competent person before any decision on further use.

Question 48: What is the UKCA marking and when is it required?

It is the UK Conformity Assessment marking required for PPE sold in Great Britain post-Brexit (Correct answer)
It is a quality award
It replaces the CSCS card
It is only needed for imported PPE

Correct answer: It is the UK Conformity Assessment marking required for PPE sold in Great Britain post-Brexit

The UKCA (UK Conformity Assessment) marking replaced the CE marking for PPE placed on the market in Great Britain after Brexit. It confirms the product meets UK safety standards. CE marking remains valid in Northern Ireland.

Question 49: What is the 'polluter pays' principle in UK environmental law?

It only applies to industrial factories
It means the government pays for all pollution cleanup
The person or organisation that causes pollution is legally and financially responsible for cleaning it up and any resulting environmental damage — this principle underpins the Environmental Protection Act 1990 and Environmental Damage Regulations 2009 (Correct answer)
The principle has no legal standing in the UK

Correct answer: The person or organisation that causes pollution is legally and financially responsible for cleaning it up and any resulting environmental damage — this principle underpins the Environmental Protection Act 1990 and Environmental Damage Regulations 2009

The 'polluter pays' principle is a fundamental tenet of UK environmental law, enshrined in the Environmental Protection Act 1990 and the Environmental Damage (Prevention and Remediation) (England) Regulations 2009. The person or organisation responsible for causing pollution must bear the cost of cleanup, remediation, and any damage to the environment. On construction sites, this means the contractor is liable for pollution incidents.

Question 50: What is the difference between a management survey and a refurbishment/demolition survey for asbestos?

A management survey is for houses and a refurbishment survey is for commercial buildings
There is no difference — they are the same survey
A management survey locates asbestos-containing materials likely to be disturbed during normal occupancy, while a refurbishment/demolition survey is more intrusive and identifies all asbestos before building work begins (Correct answer)
A refurbishment survey is cheaper and less thorough

Correct answer: A management survey locates asbestos-containing materials likely to be disturbed during normal occupancy, while a refurbishment/demolition survey is more intrusive and identifies all asbestos before building work begins

Under the Control of Asbestos Regulations 2012 and HSG264, a management survey is the standard survey for managing asbestos during normal occupation — it locates ACMs that could be disturbed by routine maintenance. A refurbishment/demolition survey is fully intrusive, accessing all areas including behind walls and above ceilings, and is required before any refurbishment or demolition work to identify all ACMs.

Question 51: What action should be taken with PPE after exposure to a hazardous substance?

Return it to the supplier
Reuse it after shaking off the dust
Store it with clean PPE
Decontaminate or dispose of it according to the manufacturer's instructions and COSHH assessment (Correct answer)

Correct answer: Decontaminate or dispose of it according to the manufacturer's instructions and COSHH assessment

PPE contaminated with hazardous substances must be decontaminated following the manufacturer's instructions and COSHH assessment, or safely disposed of as hazardous waste if decontamination is not possible.

Question 52: What is the purpose of an Environmental Impact Assessment (EIA) for a major construction project?

To systematically identify, predict, evaluate, and mitigate the environmental effects of a proposed development before planning permission is granted, as required by the Town and Country Planning (Environmental Impact Assessment) Regulations 2017 (Correct answer)
To calculate the project's profit margin
To assess the health of workers on site
An EIA is only required outside the UK

Correct answer: To systematically identify, predict, evaluate, and mitigate the environmental effects of a proposed development before planning permission is granted, as required by the Town and Country Planning (Environmental Impact Assessment) Regulations 2017

Under the Town and Country Planning (EIA) Regulations 2017, certain types of major development must undergo an Environmental Impact Assessment before planning permission can be granted. The EIA process identifies likely significant environmental effects (noise, air quality, ecology, water, landscape, heritage), proposes mitigation measures, and is documented in an Environmental Statement submitted with the planning application.
