NEBOSH Workplace Hazard Identification and Risk Assessment — Questions and Answers
Question 1: What is the five-step risk assessment process recommended by NEBOSH?
- Only identify hazards
- Identify hazards, identify who might be harmed, evaluate risks and decide on precautions, record findings, and review and update regularly (Correct answer)
- Assess and record only
- Hire a consultant to do it
Correct answer: Identify hazards, identify who might be harmed, evaluate risks and decide on precautions, record findings, and review and update regularly
The five steps are: 1) Identify hazards, 2) Decide who might be harmed and how, 3) Evaluate the risks and decide on precautions, 4) Record significant findings, 5) Review and update the assessment regularly.
Question 2: What is the difference between a hazard and a risk in NEBOSH terminology?
- They are the same thing
- A hazard is something with the potential to cause harm; risk is the likelihood and severity of that harm actually occurring (Correct answer)
- Risk is always higher than the hazard
- Hazards are physical and risks are financial
Correct answer: A hazard is something with the potential to cause harm; risk is the likelihood and severity of that harm actually occurring
A hazard is anything with the potential to cause harm (chemicals, electricity, working at height). Risk is the likelihood that the harm will occur combined with the severity of that harm.
Question 3: What heat-related hazards are particularly relevant to Gulf region workplaces?
- Heat is not a workplace hazard
- Heat stroke, heat exhaustion, dehydration, and reduced cognitive function from working in temperatures exceeding 45°C common in UAE summer months (Correct answer)
- Only sunburn is a concern
- Heat only affects outdoor workers
Correct answer: Heat stroke, heat exhaustion, dehydration, and reduced cognitive function from working in temperatures exceeding 45°C common in UAE summer months
Gulf region temperatures regularly exceed 45°C, creating hazards including heat stroke (life-threatening), heat exhaustion, severe dehydration, reduced mental alertness leading to errors, and thermal burns from hot surfaces.
Question 4: What is a risk matrix and how is it used in risk assessment?
- A mathematical formula for calculating costs
- A grid that plots the likelihood of harm against its severity to determine the risk level (low, medium, high) and prioritize control measures (Correct answer)
- A type of PPE selection tool
- A legal document required by regulators
Correct answer: A grid that plots the likelihood of harm against its severity to determine the risk level (low, medium, high) and prioritize control measures
A risk matrix is a semi-quantitative tool that combines the likelihood of occurrence (unlikely to very likely) with severity of harm (minor to catastrophic) to categorize risks and prioritize which require immediate action.
Question 5: Who should be involved in conducting workplace risk assessments?
- Only the safety officer
- Competent persons with relevant knowledge, involving workers who understand the actual tasks, and reviewed by management (Correct answer)
- Only external consultants
- Anyone available, no competence needed
Correct answer: Competent persons with relevant knowledge, involving workers who understand the actual tasks, and reviewed by management
Risk assessments should be conducted by competent persons with knowledge of the work being assessed, actively involving workers who perform the tasks (they understand the real hazards), and reviewed by management for resource decisions.
Question 6: What types of workplace hazards must be considered in a NEBOSH risk assessment?
- Only physical hazards
- Physical, chemical, biological, ergonomic, psychosocial, and environmental hazards applicable to the specific workplace (Correct answer)
- Only the most obvious hazards
- Only hazards that have caused accidents before
Correct answer: Physical, chemical, biological, ergonomic, psychosocial, and environmental hazards applicable to the specific workplace
A comprehensive risk assessment considers all hazard categories: physical (noise, vibration, falls), chemical (substances), biological (pathogens), ergonomic (manual handling), psychosocial (stress), and environmental (heat, weather).
