5 Steps of Risk Assessment in Nebosh

Risk Assessment is “a logical process of collecting information &
making judgments against standards to establish whether or not risks
are adequately controlled”
Or Risk Assessment is “Evaluating & analyzing the risks arising from
hazards, and checking the existing control measures & identifying
additional controls if needed”

5 Steps of Risk Assessment

1- Define the activity & identify the hazards:
Sources used to identify hazards
- Task observation
- Accident, ill-health & near miss records
- Experts & workers carrying out the assessed task
- Workplace inspections, Job safety analysis (JSA)
- Local legislations & legal standards
- Company policies & work procedures

2- Decide who might be harmed and how:
- Consider both employees & non-employees (contractors,
visitors & members of the public)
- Consider groups at special risk (pregnant women, young and
old workers & disabled workers)

3- Evaluate, analyze the risk and check the existing precautions
& control measures:
- Estimate, analyze & rank the risk considering both likelihood
and Severity of the harm using risk assessment matrix (5X5)
- Check the existing control measures & decide whether they are
adequate or additional precautions are needed

Record the findings:
Everything should be recorded & documented; such as
- The details of the assessors
- Date, time & location of the assessment,
- Description of the assessed activity & types of hazards
- People who might be harmed
- Level of the risk and control measures that should be taken

5- Review the assessment and revise if necessary:
- After any change such as new equipment used in the activity or
a new legislation or periodically
