A Job Hazard Analysis (JHA), also known as a process hazard analysis, is a systematic approach to identify and evaluate potential hazards associated with a specific job or task 12, 1, 3, 8. The goal is to implement controls to eliminate or minimize these hazards, preventing accidents and injuries [1]. Here's what a JHA form typically involves:

1. Core Task Definition: Clearly define the scope of work being analyzed [2].
2. Hazard Identification: Identify potential hazards associated with each step of the job. This includes [2]:
   • Sources of light radiation [3]
   • Falling objects [3]
   • Sharp objects [3]
   • Rolling or pinching objects [3]
   • Electrical hazards [3]
3. Risk Assessment: Evaluate the level of risk for each identified hazard, considering the likelihood of occurrence and the severity of potential consequences [3].
4. Control Measures: Determine and implement appropriate control measures to eliminate or mitigate each hazard. These can include 1, 3:
   • Engineering controls 2, 13
   • Administrative controls 2, 13
   • Personal protective equipment (PPE) 2, 13
5. Communication Procedures: Establish clear communication procedures for all crew members involved in the job [2].
6. Emergency Action Plan: Develop a site-specific emergency action plan, including the location of first aid equipment and rescue gear [2].
7. Regular Review: Update and revalidate the JHA regularly, especially after incidents or changes in the process 1, 3, 7, 8.

To ensure a comprehensive JHA, consider the following methodologies 1, 3, 8:

• What-If analysis 1, 3, 8
• Checklist 1, 3, 8
• Hazard and Operability Study (HAZOP) 1, 3, 8
• Failure Mode and Effects Analysis (FMEA) 1, 3, 8
• Fault Tree Analysis 1, 3, 8

Remember to involve workers in the hazard assessment and control process [1].
