Job Hazard Analysis
Introduction
Job hazard analysis is, carefully studying and recording each step of a job, identifying existing or potential job hazards (both Safety and Health), and determining the best way to perform the job to reduce or eliminate these hazards.
Selecting Jobs for Analysis
Review job injury and illness reports.
Jobs with the highest rates of accidents and injuries should be conducted first.
New jobs and jobs where changes have been made should follow.
Eventually, a job hazard analysis should be conducted for all jobs in the workplace.
Breaking Down the Job
List each step of the job in order of occurrence as you watch the employee performing the job.
Be sure to record enough information to describe each job action.
Later go over the job steps with the employee.
Worker Performing the Basic Job Steps for Grinding Iron Casting
Step one
Reach into metal box to right of machine, grasp casting and carry to wheel.
Step Two
Push casting against wheel to grind off burr.
Step Three
Place finished casting in box to left of machine.
Identifying Hazards
Examine each step to determine hazards that exist or that might occur.
Ask yourself these kinds of questions:
Is the worker wearing clothing or jewelry that could get caught in the machinery?
Are there fixed objects that may cause injury, such as sharp machine edges?
Identifying Hazards
Can the worker get caught in or between machine parts?
Is the worker positioned to the machine in a way that is potentially dangerous?
Can the worker be injured from lifting objects, or from carrying heavy objects?
Environmental hazards: dust, chemicals, radiation, welding rays, heat, or excessive noise result from the performance of the job?
Identifying Hazards
Strike hand on edge of metal box or casting.
Cut hand on burr.
Drop casting on toes.
Identifying Hazards
Strike hand against wheel.
Flying sparks, dust, or chips.
Wheel breaking.
Not enough of wheel guarded.
No dust removal system.
Sleeves could get caught in machinery.
Identifying Hazards
Strike hand against metal box or casting.
Evaluating The Hazards
What events could lead to an injury or illness for each hazard you identified.
Recommendations
Recommendations should be based on the reliability of the solution.
Hierarchy of control:
Elimination
Substitution
Isolation
Engineering Control
Administration Control
PPE
New Procedure or Protection
Step one
Provide gloves and safety shoes
Step Two
Provide larger guard over wheel.
Install local exhaust system.
Provide safety goggles.
Short or tight fitting sleeves.
Step Three
Provide for removal of completed stock.
