How to Conduct a Job Hazard Analysis

How to Conduct a Job Hazard Analysis

​​​The three steps to conduct a Job Hazard Analysis (JHA):

  1. Break the job down into its basic steps
  2. Identify the hazards that are present in each of the steps
  3. Develop controls for all hazards that you have identified
If you have more than 20 workers at your workplace, you are required to have a Safety and Health Program. Your SWP’s must be referenced in the section of your Safety and Health Program that relates to hazard identification and control (W210 7.4(5)(b)).

​​​Job Steps​​​

​Hazards

Controls​

Every task can be broken down into steps. This sequence of steps will eventually become the basis of the safe work procedure.

Identifying every step of the task is
essential to the end result. Ensure you write down everything the worker does. After each step is identified, you can go back and combine things or eliminate
unnecessary detail.

Limit the number of steps that you
actually record. If there are too many steps to your job, you may need to look at breaking the job down into two jobs. You generally should not have any more than 15 steps in your job.

Workers must be an integral part of this process.

​

Identify the hazards present in each of the job steps. 

Material hazards 

  • Electrical 
  • Sharp points or edges 
  • Pinch points 
  • Material falling 
  • Surfaces causing falls 
  • Working at heights 
  • Moving machinery 
  • Fire and explosion 

Musculoskeletal hazards 

  • Awkward or sustained posture 
  • Forceful exertion 
  • Repetitive motions 
  • Vibration 
  • Skin compression 

​Hygiene/health hazards 

  • Chemical hazards (acids, solvents, fumes) 
  • Biological hazards (bacteria, viruses) 
  • Physical agents (heat, noise, radiation) 
  • Psycho-social hazards (harassment, time constraints, violence)

​What controls can be implemented for each of the hazards that you identified?
 

At the source 

  • Elimination 
  • Substitution 
  • Redesign 
  • Isolation 
  • Automation 

Along the path 

  • Relocation 
  • Barriers 
  • Absorption 
  • Dilution 

At the worker’s level 

  • Administrative controls 
  • Orientation, training and supervision
  • Work procedures 
  • Emergency planning 
  • Housekeeping 
  • Hygiene practices 
  • Personal protective equipment (PPE) 




Example: Job Hazard Analysis (Sample Only)


Company Name: ABC Carpentry
Date: April 16, 2015

​Job name: 

Woodworking band saw 

​Facility: 

Shop 1 

​Conducted by: 

J. Carpenter 

​Job Steps

​Hazards

​Control Measure

​1. Place material in front of blade on work platform 
  • ​Debris on platform 
  • Accidentally start saw while preparing 
  • Awkward posture - lifting and twisting (material handling) 
  • Forceful exertion lifting heavier pieces of wood 
  1. ​Inspect to ensure clean work platform and equipment 
  2. Electrically isolate before starting anything else 
  3. Describe safe lifting/materials handling (also cover in lift/materials handling training) 
  4. Identify proper hand positioning and safe zones 
  5. Locate and train on use of emergency shut off button/ procedures 
​2. Turn on saw 
  • ​Electrical shock 
  • Exposed blade 
  • Noise 
  • Blade break 


  1. ​Inspect electrical cord and switch 
  2. Adjust guard to 1/8” above wood to be cut 
  3. Hearing protection 
  4. Inspect blade and wear eye protection 
​3. Push piece of material through blade 
  • ​Knots/nails in wood – kickback 
  • Amputation or cuts – hands contact with blade 
  • Saw dust in eyes 
  • Saw dust inhaled (toxic – hardwoods) 
  • Awkward postures due to leaning and reaching 
  1. ​Inspect wood and push through slowly 
  2. Ensure safe zone is identified and jigs or push sticks are used if hand would leave the safe zone 
  3. Eye protection 
  4. Engage dust collection system and ensure it is included in exposure/maintenance program 
  5. Position body to avoid exposure to awkward and sustained postures (also cover in body posture training) 
​4. Remove material from platform 
  • ​Exposed blade – cuts 
  • Material fall and strike feet 
  1. ​Use proper hand positioning, shut off saw, use a push stick to remove pieces close to blade 
  2. Wear safety footwear 
​5. Clean off saw
  • ​Saw dust in eyes 
  • Saw dust inhaled 
  1. ​Eye protection 
  2. Disposable respirator (N95) 

All Job Hazard Analysis samples obtained from other organizations or literature must be thoroughly reviewed to ensure they are accurate for your workplace and your jobs!
