picture - 01

What is Job Safety Analysis?

A specific risk assessment, written document, part of a safe system of work, step by step identifying the hazards of a specific task and decide on control measures to eliminate or minimize the hazard risks. It is sometimes referred to as a JHA (job hazard analysis) or task analysis.

A legal obligation of an employer to provide a safe workplace and equipment to protect workers and property, using JSA to identify hazards and precautions.

What are the basic steps of a JSA?

There are five steps of JSA

  1. Select a job

  2. Break the job into small activity/ job sequence
  3. Identify the hazards of each activity/step
  4. Decide on control measures
  5. Monitoring the effectiveness of the control measure 

How do I write a good JSA?

Follow the 5 steps of JSA

1. Select a job

Select a job with high risk, the potential for injury or illness such as the work at height or scaffolding erection, dismantle or modification,

2. Break the job into small activity/ steps

Scaffolding erection, dismantle or modification contains many individual tasks, try to spread the job into small activities. So clearly hazards are identified, such as:

• Mobilization of personnel and material

• Erection, dismantle, and modification

• Housekeeping

3. Identify the hazards of each activity/step

Identify hazards such as slip, trip and fall, pinch point, manual handling risk, vehicle movement risk etc.

To identify hazards use the hierarchy of control

• Elimination - Remove Risks

• substitution - Replace hazards of risk

• Engineering control - Isolate the people from risk

• Administrative control - Train the personnel

• PPE - Use last defence such as safety glass

4. Decide on control measures

Once identified hazards then decide suitable precautions to eliminate or minimize the risk of the hazards such as using the full body for work at height is a suitable precaution to eliminate fall hazards,

5. Monitoring the effectiveness of the control measure

Monitor what you have decided precautions are effectiveness? control measures are being implemented?

A new hazard or risk has identified, what about the review of the control measures?
