Job Hazard Analysis | Steps in JHA
GUIDANCE
_______________________________________________________________________________________
1. To break down the job for a JHA, you have to:
 List each task in the order it’s performed
 Describe each action involved in performing each task
 Consider the conditions under which the job is performed
 Think about safety issues involved at each step in the job
2. Common job hazards that might be identified by a JHA include:
 Impact, such as from being struck by an object or falling and hitting the ground
 Penetration by sharp or pointed objects that cause cuts or punctures
 Caught between two objects, which can cause crushing or amputations
 Harmful airborne contaminants from chemicals, dust, mold, and so on
 Repetitive motions and awkward postures, which can cause musculoskeletal disorders, or MSDs
 Heat or cold
 Compression, which can cause broken bones, amputations, and other serious bodily damage
 Chemical exposures, such as getting chemicals on the skin or in the eyes or accidentally
swallowing hazardous chemicals
 Optical radiation, which can cause serious eye damage and even blindness.
3. When hazards are evaluated, questions like these should be asked:
 Is this a safety or health hazard?
 Could this hazard cause an injury or illness?
 How serious is the risk?
 Is this hazard always present when the job is being performed or is it an intermittent hazard?
 Are engineering and/or administrative controls currently being used to prevent injuries and
illness effective?
 Is the right PPE being used to protect against hazards?
 Is safety training creating sufficient awareness of the hazards and knowledge of the precautions
that must be taken to prevent accidents?
 Are the protective measures currently in place adequate or are additional or different measures
required to ensure safety?
4.
As a result of a JHA:
 A job might be performed differently
 The work area or workstations might be reconfigured to make the job safer
 Less hazardous materials might be substituted
 There might be a switch from manual to mechanical techniques to reduce the exertion required
to perform the job and prevent stress and strain injuries
 Safety training might be added, improved, or changed
 Tools or equipment might be changed
 PPE might be changed or added
 The most hazardous tasks might be performed less often
