Utility strike: gas, power, water or fiber in the way
Cave-in: a trench wall gives way and buries someone
Struck-by: the bucket or the swinging excavator
Falling into the trench, or tools and spoils falling in

Controls

  • Call 811 and pothole before digging. Hand dig or vac near the marks.
  • Trench box or slope at 5 ft or deeper. Over 20 ft deep, an engineer designs the protection.
  • Competent person checks the trench daily, before each shift and after rain.
  • Ladder, ramp or stairs within 25 ft of every worker in trenches 4 ft or deeper.

JHA templates by task

Each template lists the hazards, the controls, the PPE and the OSHA rules for one kind of work, plus the toolbox talk that goes with it. Start from one, then add what's different on your site today.

How to write a job hazard analysis

  1. Pick the task. One JHA per kind of work: trenching, setting pipe, paving. Not one for the whole job.
  2. Break it into steps. What the crew does, in order. Five to eight steps is plenty.
  3. List the hazards for each step. What could hurt someone: struck-by, caught-between, falls, cave-in, electrical, heat.
  4. Write the control for each hazard. Get rid of it first, then guard it, then train, then PPE.
  5. Name the competent person. Trenching, scaffolds and fall protection need one by name.
  6. Walk it with the crew and sign. A JHA nobody read is paperwork. Five minutes at the tailgate makes it real.

Tomorrow, the crew signs it on one phone.

Dozer writes the JHA and the toolbox talk from what you say and what the cameras saw yesterday. The crew signs on the foreman's phone, and it files itself in the site's day.

  • One JHA per task, per day, in under a minute
  • The toolbox talk that matches the work
  • Signatures on one phone, no clipboard
  • Filed with the daily log, ready for an inspector

Questions crews ask

What's the difference between a JHA and a JSA?

Nothing that matters on site. A job hazard analysis (JHA) and a job safety analysis (JSA) both break a task into steps, list the hazards of each step and the control for each hazard. Some companies say AHA (activity hazard analysis), which is what USACE's EM 385-1-1 calls it.

Does OSHA require a JHA?

Federal OSHA doesn't require a written JHA for most construction work, but it's the easiest way to show you planned for the hazards its rules cover. Many GCs require one daily, and USACE jobs require an AHA for every phase of work under EM 385-1-1.

What goes in a job hazard analysis?

The task and its steps, the hazards for each step, the control for each hazard, the PPE, who's the competent person, and signatures from the crew. OSHA's guide is publication 3071.

Is the JHA builder free?

Yes. The template part runs right in the page. The AI part, which writes it from a sentence, needs the Dozer API and is also free to use here.
