NEBOSH Work Environment 3 — Questions and Answers
Question 1: What is the significance of Regulation 5 of the Workplace (Health, Safety and Welfare) Regulations 1992?
- It sets maximum working hours
- It requires that the workplace, equipment, devices and systems are maintained in efficient working order and good repair (Correct answer)
- It governs fire escape routes
- It regulates noise levels in the workplace
Correct answer: It requires that the workplace, equipment, devices and systems are maintained in efficient working order and good repair
Regulation 5 imposes a general duty to maintain the workplace, its equipment, devices, and systems in an efficient state, in efficient working order, and in good repair. Where maintenance involves a risk to health and safety, a suitable record of the maintenance must be kept.
Question 2: How does the Workplace Regulations address the issue of overcrowding in workrooms?
- By limiting the number of workers per room to 10
- Regulation 10 requires workrooms to have sufficient floor area, height and unoccupied space for health, safety and welfare (Correct answer)
- By requiring windows in every workroom
- By mandating maximum occupancy signs on all doors
Correct answer: Regulation 10 requires workrooms to have sufficient floor area, height and unoccupied space for health, safety and welfare
Regulation 10 requires that every workroom has sufficient floor area, height, and unoccupied space to ensure health, safety and welfare. The ACoP specifies 11 cubic metres per person as a minimum, and this should allow workers to move about and access their workstations safely.
Question 3: On a construction site operating under CDM 2015, what welfare provision must be made for drying wet clothing?
- No specific provision is required for drying clothing
- Suitable and sufficient facilities for drying clothing must be provided (Correct answer)
- Workers must bring their own spare clothing
- Only waterproof clothing must be provided
Correct answer: Suitable and sufficient facilities for drying clothing must be provided
CDM Schedule 2 requires facilities for drying clothing on construction sites. This is particularly important because construction workers are frequently exposed to wet weather, and wearing damp clothing can lead to hypothermia and other health issues. The facilities must be adequate for the number of workers.
Question 4: Under the Health and Safety (First-Aid) Regulations 1981, what is the employer's primary duty?
- To train all workers in first aid
- To provide adequate and appropriate first-aid equipment, facilities, and personnel to enable first aid to be rendered to employees who are injured or become ill at work (Correct answer)
- To have a first aider for every 10 workers
- To maintain a direct telephone line to the emergency services
Correct answer: To provide adequate and appropriate first-aid equipment, facilities, and personnel to enable first aid to be rendered to employees who are injured or become ill at work
The First-Aid Regulations require employers to provide adequate and appropriate equipment, facilities, and personnel so that employees can receive immediate attention if injured or taken ill at work. What is 'adequate and appropriate' depends on the nature of the work, workforce size, and site hazards.
Question 5: What does the Workplace Regulations require regarding windows and transparent doors?
- All windows must be fitted with blinds
- Windows and transparent or translucent surfaces in walls, partitions, doors and gates must be made of safety material or protected against breakage where necessary to prevent injury (Correct answer)
- All ground floor windows must be toughened glass
- Windows must be openable in every room
Correct answer: Windows and transparent or translucent surfaces in walls, partitions, doors and gates must be made of safety material or protected against breakage where necessary to prevent injury
Regulation 14 requires that transparent or translucent surfaces in doors, gates, walls, and partitions must be made of safety material or adequately protected against breakage if they could cause injury. They must also be appropriately marked to make them apparent. This prevents walk-through injuries.
Question 6: What ventilation requirement applies to mechanical ventilation systems under the Workplace Regulations?
- They must be serviced by a qualified engineer monthly
- Any mechanical ventilation system must include an effective device to give visible or audible warning of failure (Correct answer)
- They must maintain a temperature of exactly 20°C
- They are only required in chemical processing plants
Correct answer: Any mechanical ventilation system must include an effective device to give visible or audible warning of failure
Regulation 6(3) specifically requires that where a mechanical ventilation system is used, it must include an effective device to give visible or audible warning of any system failure. This is because occupants might not notice a gradual deterioration in air quality if the system fails silently.
