When should a Job Hazard Analysis (JHA) be performed to be effective?

• A. During The Job Is In Progress
• B. Only After An Incident Occurs
• C. After The Job Is Completed
• D. Before Starting A Job

Answer: (D)

The main idea being tested is that a Job Hazard Analysis is a proactive planning step performed before work begins to identify hazards and put controls in place. By breaking the task into steps and examining what could go wrong at each point, you can determine the necessary preventive measures—engineering controls, procedures, training, permits, and personal protective equipment—so workers can perform the job safely. Doing this before starting ensures hazards are anticipated and addressed, giving you a concrete plan to protect the crew, rather than waiting to react after something goes wrong. If you wait until during the job, after an incident, or after the job is completed, you’ve missed the chance to prevent harm and your safety controls may be inadequate or not in place. Involving workers in the JHA also helps capture practical hazards you might not anticipate and strengthens the safeguard plan.
