Job hazard analysis software › JHA builders
JHA builders and AI JSA generators
A JHA builder starts the analysis for you in one of two ways: from a library, where you pick the activity and edit hazards and controls someone already wrote, or from a sentence, where AI drafts the JHA from the task you type. Either way you get a draft: the site's facts still come from the competent person and the crew.
Library builders and AI drafters
| Tool | How the draft starts | Risk scoring | Price to start |
|---|---|---|---|
| JSABuilder | Library: pre-loaded hazard and control libraries, JSA, JHA, AHA or custom formats, copy an existing worksheet | Yes your own probability × severity, before and after controls | $67 a year for one user; 30-day trial |
| Gadzoom | Library: thousands of JHAs and AHAs with OSHA and EM 385-1-1 references built in, generated in 46 languages | Not stated | $149 for one AHA |
| HCSS HeavyJob Safety | Library: 100+ JHA templates the foreman adjusts for the job | Yes severity | Quote |
| Safety Reports | Library: preloaded hazards and controls, or your own list | Not stated | Quote |
| Dozer | AI: type or say the day's task and it drafts steps, hazards, a control per hazard, PPE and 29 CFR 1926 cites; or start from 59 task templates | No | Free for one site, with a free account |
| JSA OnTheGo | AI: type the task details and it generates the risk assessment and PPE; or create from a previous JSA | Yes risk matrix calculator | $0.99 a JSA; $9.99 a month after a 7-day trial |
| Field1st | AI: drafts the steps, reads hazards from a photo, ranks controls by the hierarchy; a qualified person confirms and signs | Yes severity × likelihood | Quote |
| HammerTech | AI fills in a pre-task plan from a recording or a document; hazard and control libraries | High-risk tag on JHAs | Quote |
| Mitti (by SafetyCulture) | AI builds a checklist template from a description, or imports your PDF, Word or Excel form | Not stated | Free up to 10 users and 5 templates |
The top Google result for "job hazard analysis software" is Sourcetable, which generates JHA templates for Excel. That's a third kind of builder: it gives you the blank form. OSHA publishes one as a Word file (OSHA's JHA template), and the JSA template on this site lays one out column by column.
A builder's template, annotated
Here is what a builder's template gives you and what it can't. The left two columns are Dozer's trenching template, free to read, as published at trydozer.com/jha/trenching (five hazards, eight controls, cites to 29 CFR 1926.651 and 1926.652). The right column is what the competent person has to add before anyone signs.
| Hazard in the template | Template's controls | What the competent person adds on site |
|---|---|---|
| Utility strike: gas, power, water or fiber in the way | Call 811 and pothole before digging; hand dig or vac near the marks | The ticket number and its expiry; which utilities were marked; what the potholes found and at what depth; any service the marks missed |
| Cave-in | Trench box or slope at 5 ft or deeper; an engineer designs it over 20 ft; daily checks before each shift and after rain | The soil type from the classification; the actual depth; which box, and its rating from the tabulated data; the competent person's name |
| Struck-by: the bucket or the swinging excavator | Stay out of the swing radius; nobody under a raised bucket or load | How the swing radius is barricaded; who spots; how traffic and delivery trucks are kept out |
| Falling into the trench, or tools and spoils falling in | Spoils and equipment 2 ft back from the edge; ladder, ramp or stairs within 25 ft at 4 ft or deeper | Where the spoils go on this street; crossings and walkways; how the trench is barricaded overnight |
| Bad air or standing water | Test the air over 4 ft where bad air could build up; pump out water | Whether a sewer, fuel line or landfill is nearby; which meter and the readings; the rain forecast; where the pump discharges |
Some things no template knows: the rescue plan if someone is hurt in the trench, the nearest hospital, who else is working next to you today, and that one of the four laborers started on Monday. The template itself says so: "A starting point, not a finished JHA. Walk the site, add what's different today, and have the competent person sign it." It also lists hazards and controls for the task, not step by step; Dozer's AI draft, made in its app from a sentence, comes out in steps. For a step-by-step trenching JHA filled in for a real job, see JHA examples.
What to check in any generated JHA
- The steps match how your crew does the work. OSHA 3071 says to watch the job or walk it with the people who do it. A draft that orders steps differently from your crew will be ignored.
- Every hazard has a control, and the controls follow the hierarchy: engineering first, then procedures, then PPE. A column of "wear PPE" and "be careful" means the tool filled space.
- The cites are real. Look up two or three sections on eCFR. A wrong paragraph is a credibility problem the first time a GC's safety manager reads it.
- Nothing is generic that should be specific: depths, distances, voltages, the soil type, the names.
- Someone is responsible for each control, and the competent person is named and signs.
- The crew read it before they signed. A draft written in ten seconds tempts everyone to sign in ten seconds.
Library or AI: which fits
Choose a library builder when the same kinds of work repeat and a safety manager wants approved wording, scores and sign-off: JSABuilder adds review and approval and yearly review reminders, and Gadzoom builds in the EM 385-1-1 references federal work needs. Choose an AI drafter when the work changes daily and the foreman writes the JHA in the truck. Dozer does that free for one site (with a free account) and runs in a browser; its 59 templates are free to read on its site, but it has no risk score, no approval step and no line editor (you reword the task and draft again), and it covers US federal OSHA only. JSA OnTheGo adds a risk matrix in a phone app; Field1st and HammerTech add AI to larger platforms priced by quote. Phone apps for signing in the field are compared in JSA apps, and the full field in the job hazard analysis software comparison.
Questions
Is there a free JHA builder?
Partly. Dozer's 59 construction JHA templates are free to read at trydozer.com/jha, and its AI draft is free for one site with a free account. Mitti is free for up to 10 users and 5 active templates if you build the JSA as a checklist, JSA OnTheGo sells single JSAs for $0.99, OSHA publishes a blank JHA form as a Word file, and JSABuilder and Gadzoom offer free trials.
Can AI write a job hazard analysis?
It can write a first draft: steps, common hazards, controls, PPE and OSHA cites for the task you describe. It can't know the soil, the depth, the utilities found, the weather or the crew, so the competent person has to add those, check the cites and sign it, and the crew has to review it.
What is a JSA generator?
A tool that produces a job safety analysis for you, either by pulling a ready-made one from a library for the activity you pick or by having AI draft one from a description of the task. JSA and JHA generators are the same thing.
