Job Hazard Analysis (JHA)

NAME : ALEXIUS HENRY

(DOSH409FT01)



What is Job Hazard Analysis (JHA)?

It is a method for systematically identifying andevaluating hazards associated with a particular job ortask. It is also called ³job safety analysis (JSA)´.



EXAMPLE OF JSA FORM



Why conduct a job hazard analysis?

A job hazard analysis can prevent work-related death, injuries or illnesses by eliminating or controlling identifiedhazards.



Hazard Awareness

Accepting a risk or hazard is not the

same as eliminating or controlling it.



How do I conduct a JHA?1. Identify the job or task to be analyzed.

2. Break the job or task into key components.

3. Identify the hazards found in each key component.

4. Identify ways to eliminate or control these hazards.

5. Eliminate the hazard or install controls.

6. Keep a record of the hazards identified and stepstaken to eliminate or control them.

7. Periodically assess controls to ensure they are workingcorrectly.



WHEN SHOULD THE JHA SHOULD

BE DONE??????Any job or task that meets any of the following conditions should also have aJHA conducted for it:

New people doing the task,

Tasks that have changed,

Rarely performed jobs,



WHERE TO FIND JOBS THAT NEED TO BE ANALYSED?

Look at jobs where workers have beeninjured using existing information from:

Your accident or incident reports

Your worker compensation claims



Once you have identified jobs needing a JHA, then it is time to start conducting the JHA.

Involving employees and/or foreman orsupervisors in the JHA process allows them tobring their insights about the jobs to the

process.

Involving employees ± a good

idea



THE BREAKING DOWN!

Break job down into key components

Once a job is identified, you will need to break it

into key components or sub-tasks and list all thehazards associated with each sub-task.



Breaking job into key components - example

Changing a light bulb

Too Much Detail Too Little Detail Right Amount of Detail

Get ladder from storage.

Get new light bulb from storage.

Carry ladder and light bulb to light needing changing.

Place ladder under light to be changed.

Ensure light switch is in the off position.

Climb ladder.

Remove light cover.

Twist light bulb in a counter clock-wise direction untilit is free of the socket.

Remove old light bulb.

Insert new light bulb into socket.

Turn in a clock-wise direction until tightened.

Replace light cover.

Descend ladder.

Carry ladder back to storage.

Get a ladder and newlight bulb.

Change bulb.

Put ladder away andthrow out old light bulb.

Get ladder and new light bulb.

Turn light switch off

Place ladder under light to be changed.

Using ladder, changebulb.

Put ladder back instorage.



Ranking Hazardous Tasks

Once you have identified jobs or tasks that have the potential toor are in fact injuring workers, you will need to rank these tasks

and start addressing the most serious first.



EXAMPLE OF RANKING OR CLASSIFYING

THE HAZARD.Score Classification Description

4 Catastrophic May cause death

3 Critical May cause severe injury or illness

2 Marginal May cause minor injury or illness

1 Minor Will not cause injury or illness

Severity Table

Score Classification Description

5 f requent Very likely to occur f requently

4 probable Probably will occur at some time

3 Occasional May occur inf requently

2 Remote Unlikely, but possible

1 Improbable So unlikely, it is assumed it will not occur

Probability Table



Eliminating or controlling hazards

Af ter you have identified the jobs and evaluated its sub-tasks and hazards, you will need to identify ways toeliminate or control these hazards.



WAYS OF ELIMINATING OR CONTROLING

THE HAZARD!!!

Engineering Control

Unguarded belt

Guarded belt



Equipment Lock-out

Locking out electrical equipment or moving parts of machinery eliminates hazards during maintenance.



Administrative Controls

Administrative controls act on the worker, not the hazard.The hazard still exists, but the worker avoids the hazardby the way they do their job.



Personal protective equipment

Personal protective equipment (PPE) should be considered only af ter othercontrol methods have been tried or shown not to be feasible.

PPE should ALWAYS be the last

solution
