Free HVAC Job Hazard Analysis Template (JHA / JSA)

JHA and JSA are the same document under two names — OSHA publishes it as a job hazard analysis in OSHA 3071, and much of the industry says job safety analysis. A risk assessment is a genuinely different document. The risk assessment is a register: one row per hazard, scored likelihood × severity on a matrix, re-scored after controls, written once per project. It has no job sequence in it. The JHA is a decomposition: you break the specific job into the steps the crew will actually perform in order, and for each step you list that step's hazards and the control for each one. The sequence is load-bearing, because most HVAC injuries happen in the transitions — carrying the recovery machine up the ladder, breaking the roof-hatch threshold, setting the condenser off the rigging. Those are steps, and a hazard register has no place to put them. Use the risk assessment to decide what the project's hazards are; use the JHA to plan one job before the crew does it.

Enough that each step is a distinct action with its own hazards, and few enough that the crew reads it. OSHA 3071 does not set a number — it warns against a breakdown that is so detailed it becomes unusable and one so general that hazards hide inside a step. The practical test is whether a step has more than one control answer; if it does, it is really two steps. This builder caps the form at twelve, which is an application limit rather than a standard, and most service jobs land between four and eight.

Because PPE is the bottom of the hierarchy of controls and it is where a weak analysis lands by default. NIOSH ranks the five tiers — elimination, substitution, engineering, administrative, PPE — and states that PPE is least effective, since it does nothing to the hazard and fails at the moment the hazard reaches the worker. A JHA that answers every step with "wear gloves and safety glasses" has documented that nothing was controlled. The flag is not a block and it is not an error: for some hazards, such as splash to the face, PPE is the honest answer. It is there so the choice is visible rather than automatic.

Four, and they are triggered by the hazards you select rather than by a checkbox. Permit-required confined space entry (attic, crawlspace or plenum on the HVAC library), excavation, hot work, and energized work. Selecting a hazard that carries one puts the permit in the block, names the step numbers that triggered it, and holds the analysis at "permit required — cannot sign off" until you enter the reference. Any still-blank reference prints above the letterhead in the PDF, not on page two.

Frequently, which is why the library asks rather than assumes. A space is confined when it is large enough to enter, has limited means of entry or exit, and is not designed for continuous occupancy — a description that fits a great many attics, crawlspaces and plenums. It becomes permit-required once it holds or could hold a hazardous atmosphere, engulfment potential, a trapping configuration, or any other recognised serious hazard; summer attic heat alone can get there. Which rulebook applies follows the work: 29 CFR 1910.146 for service and maintenance, 29 CFR 1926 Subpart AA for construction. Subpart AA additionally requires a competent person to identify the spaces and continuous atmospheric monitoring where possible.

Both of them, and which applies depends on the standard covering the work rather than the size of the drop. Construction triggers at 6 feet under 29 CFR 1926.501(b)(1); general industry — routine service, maintenance and repair on an existing system — triggers at 4 feet under 29 CFR 1910.28(b)(1)(i). HVAC crosses that line constantly, so this form asks for the work context up front and carries both numbers rather than printing one as "the OSHA height". Rooftops add tiers on the general-industry side under 1910.28(b)(13); construction has no tiers.

No, and every export says so. It is a template the employer must adapt to the actual job, the actual site and any state plan that applies, and must train the crew on. A completed analysis records that the analysis was done. It does not replace your written safety program, your permit-required confined space program, your energy control procedures, or any permit system — and where this analysis triggers a permit, that permit is a separate document that must be issued before work starts. Citations appear to explain why an item is in the library, not to certify anything.
