CSCS Environmental Awareness 4 — Questions and Answers
Question 1: What is the purpose of a spill kit on a construction site and what should it contain?
- A spill kit is a first aid kit for chemical burns
- A spill kit is designed to contain and clean up accidental spills of oil, fuel, chemicals, or other pollutants before they reach drains or watercourses — it should contain absorbent granules, pads, booms, disposal bags, and PPE (Correct answer)
- A spill kit is only needed at petrol stations
- A spill kit is a tool for cleaning concrete spillages
Correct answer: A spill kit is designed to contain and clean up accidental spills of oil, fuel, chemicals, or other pollutants before they reach drains or watercourses — it should contain absorbent granules, pads, booms, disposal bags, and PPE
Spill kits are an essential pollution prevention measure on construction sites. They must be readily available wherever oil, fuel, or chemicals are stored or used. A typical kit contains absorbent granules, absorbent pads and rolls, containment booms (for watercourses), drain mats or covers, heavy-duty disposal bags, and PPE (gloves, goggles). All operatives should be trained in their use. This supports compliance with the Environmental Permitting Regulations 2016.
Question 2: What are the requirements for storing hazardous waste on a construction site before collection?
- Hazardous waste can be stored with general waste
- Hazardous waste must be stored separately from non-hazardous waste in clearly labelled, secure, and appropriate containers, on an impermeable surface with secondary containment, and collected by a registered hazardous waste carrier within a reasonable timeframe (Correct answer)
- There are no specific storage requirements for hazardous waste
- Hazardous waste must be buried on site
Correct answer: Hazardous waste must be stored separately from non-hazardous waste in clearly labelled, secure, and appropriate containers, on an impermeable surface with secondary containment, and collected by a registered hazardous waste carrier within a reasonable timeframe
Under the Hazardous Waste (England and Wales) Regulations 2005 and the Environmental Permitting Regulations 2016, hazardous waste on construction sites must be: stored separately from other waste types; in suitable, sealed, and clearly labelled containers; on an impermeable surface with secondary containment to prevent leaks; secured against unauthorised access; and collected by a registered hazardous waste carrier with the appropriate consignment documentation.
Question 3: What is the maximum noise level at which hearing protection must be provided on a UK construction site?
- There is no specific noise level — it is left to the contractor's discretion
- Under the Control of Noise at Work Regulations 2005, hearing protection must be provided at the lower exposure action value of 80 dB(A) daily exposure and must be worn at the upper exposure action value of 85 dB(A) — the exposure limit value is 87 dB(A) taking account of hearing protection (Correct answer)
- 100 dB(A)
- Only when workers complain about noise
Correct answer: Under the Control of Noise at Work Regulations 2005, hearing protection must be provided at the lower exposure action value of 80 dB(A) daily exposure and must be worn at the upper exposure action value of 85 dB(A) — the exposure limit value is 87 dB(A) taking account of hearing protection
The Control of Noise at Work Regulations 2005 set three levels: Lower Exposure Action Value (80 dB(A) LEPd) — employers must provide hearing protection on request and give information on risks; Upper Exposure Action Value (85 dB(A) LEPd) — hearing protection must be worn, hearing protection zones designated and signed; Exposure Limit Value (87 dB(A) LEPd taking account of hearing protection) — must never be exceeded.
Question 4: 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
- 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 driver has a valid driving licence
- 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 5: What is the purpose of wheel washing facilities at the exit of a construction site?
- To clean vehicles for aesthetic reasons
- To remove mud, dirt, and debris from vehicle tyres and bodies before they enter the public highway, preventing the deposit of material on roads which is an offence under the Highways Act 1980 and a source of dust nuisance (Correct answer)
- Wheel washing is only required at quarries
- To wash workers' boots at the end of the day
Correct answer: To remove mud, dirt, and debris from vehicle tyres and bodies before they enter the public highway, preventing the deposit of material on roads which is an offence under the Highways Act 1980 and a source of dust nuisance
Wheel washing prevents mud and debris from being carried onto public roads, which is an offence under Section 148 of the Highways Act 1980 (depositing material on a highway) and can cause road safety hazards and dust nuisance. Planning conditions often require wheel washing facilities. Road sweeping should also be employed. Failure to prevent mud on roads can result in enforcement action by the local authority and highway authority.
Question 6: What is the construction industry's responsibility regarding invasive non-native species such as Japanese knotweed?
- Invasive species are not a concern for construction
- Under the Wildlife and Countryside Act 1981, it is an offence to cause Japanese knotweed and other listed invasive species to grow in the wild — construction sites must have a management plan, contaminated soil must be treated as controlled waste, and specialist treatment may be required before development (Correct answer)
- Japanese knotweed can be composted on site
- Only the landowner is responsible, not the contractor
Correct answer: Under the Wildlife and Countryside Act 1981, it is an offence to cause Japanese knotweed and other listed invasive species to grow in the wild — construction sites must have a management plan, contaminated soil must be treated as controlled waste, and specialist treatment may be required before development
Under Section 14 of the Wildlife and Countryside Act 1981, it is an offence to plant or cause to grow in the wild any plant listed on Schedule 9, including Japanese knotweed. On construction sites, a management plan is required, contaminated soil must be disposed of as controlled waste at a permitted facility, and specialist herbicide treatment or excavation may be needed. The Anti-social Behaviour, Crime and Policing Act 2014 also provides enforcement powers.
