Job safety analysis procedure
- select the job
- break down into job steps
- observe the examine risks
- develop control measures
- formulate safe system of work
- review and maintain
criteria include:
- accidents / loss history
- potential severity
- probability of recurrence
- legal requirements
- newness of the job
- number of workers at risk
safe systems of work:
- safe design
- safe installation
- safe premises and plant
- safe tools and equipment
- correct use of plant, tools and equipment (training and supervision)
- effective planned maintenance of plant and equipment
- proper working environment ensuring adequate lighting, heating and ventilation
- trained and competent employees

job step - risk factor - control action
system safety:
- originated in aerospace/aviation
- concern: whole system safety, not just tasks
- it involves: hazard identification, safety in design, continuous monitoring
Method analysis:
- hazard and operability (HAZOP)
- technique of operation review (TOR)
- Gross Hazard Analysis
- Classification Of Risks
- Risk Ranking
- Failure of Modes and Effect Analysis
- Fault Tree Analysis
