What is a THA/JHA?

• A. Task/Job Hazard Analysis done before work to identify hazards and mitigations.
• B. A daily log of equipment usage.
• C. A process to train new hires.
• D. A method for approving budgets.

Answer: (A)

A THA/JHA is a proactive safety step done before any work begins. It means breaking down the task into individual steps, looking at what could go wrong at each step, and deciding controls to prevent problems. The idea is to identify hazards ahead of time and put in mitigations—engineering controls, PPE, procedures, and administrative measures—so the job can be done as safely as possible.

In practice, you’d map out the task, step by step, then for each step note potential hazards (like electric shock, hot surfaces, pinch points, or slips). You’d determine what mitigations apply, such as de-energizing and locking out equipment, using anti-static protection, wearing proper PPE, and following a clear sequence or permit requirements. This planning helps prevent injuries and incidents by making safety part of the plan before any work starts.

This isn’t a daily log of equipment, it isn’t a training program, and it isn’t a budgeting process. It’s specifically about identifying hazards and the ways to control them before performing the job. For example, before replacing a server component, you’d plan all steps, verify power is off, implement lockout/tagout, wear ESD-safe gear, and outline safe handling to avoid shocks, burns, or equipment damage.
