Job hazard analysis software, compared
Job hazard analysis (JHA, or JSA) software breaks a task into steps, lists each step's hazards and controls, collects the crew's signatures and keeps the record. Pick by who writes the JHAs: a foreman writing one every morning needs a phone tool that drafts it and gets it signed; a safety department needs scoring and approvals.

What a finished JHA looks like
Whatever the tool, the output is the table Job Hazard Analysis (OSHA 3071) describes: the job in steps, what can go wrong in each, and a control for each hazard, engineering before administrative before PPE. Here are the first three steps for an 8-inch water main in an 8-foot trench with a trench box.
| Step | Hazards | Controls | 29 CFR |
|---|---|---|---|
| 1. Confirm utilities and set up the work zone | Striking a marked or unmarked gas, power, water or fiber line; traffic or trucks entering the work area | Valid 811 ticket and marks checked; pothole (hand dig or vacuum) to expose lines before the bucket gets close; cones, barricades and a flagger set up per MUTCD Part 6 where traffic passes; high-visibility vests for anyone exposed to traffic | 1926.651(b), 1926.651(d), 1926.201(a) |
| 2. Excavate and place spoils | Struck by the excavator's swing or bucket; spoils or equipment rolling into the trench; wall collapse as depth increases | Nobody under the bucket or a raised load; swing radius barricaded; spoils and equipment at least 2 ft from the edge; competent person classifies the soil before anyone enters | 1926.651(e), 1926.651(j)(2), 1926.652 |
| 3. Set the trench box and enter | Cave-in at 5 ft or deeper; no way out; bad air near the sewer line | Box rated for the depth per the manufacturer's tabulated data; ladder inside the box within 25 ft of every worker; air tested before entry; competent person inspects before each shift and after rain | 1926.652(c)(2), 1926.651(c)(2), 1926.651(g)(1), 1926.651(k) |
What each tool does
Mitti (by SafetyCulture)
Best free app to build your own JSA in
Mitti is SafetyCulture's inspection app under a new name. You build the JSA as a checklist template, by hand, with its AI or from your paper form, then run it on a phone, offline if needed, with photos and signature questions. Free covers 10 users and 5 active templates; Premium is $24 a seat a month billed yearly ($29 monthly), with cheaper Guest seats. Its template library is general, not construction JHAs.
Dozer
Best for a foreman's daily JHA, signed on one phone
Dozer is an AI foreman for construction job sites, and JHAs are one of its apps. The foreman types or says the day's task and Dozer drafts the JHA: steps, hazards, a control for each, PPE, 29 CFR 1926 cites and a toolbox talk, or shows the closest of 59 task templates. The crew signs on one phone passed hand to hand.
Free covers one site, and the crew never pays; each further site is $99 a month on the Site plan. The signed JHA is saved to the site with a PDF to print or share; there is no step to email it to the GC. It has no risk scoring, approval step or line-by-line editor, covers federal OSHA only, needs a connection to save, and is new in 2026: a browser app, with no App Store or Google Play listing on November 13, 2026.
JSABuilder
Best low-cost library with risk scoring and approvals
JSABuilder is for the person who writes and maintains a company's JHAs: hazard and control libraries, JSA, JHA and AHA formats, photos per step, probability-and-severity scoring before and after controls, reviewer routing, annual review reminders and PDF or Word output. One plan: $67 a year for the first user, $49 each for users 2 to 50, after a 30-day trial. Its site doesn't say how crews sign, and names no phone app.
JSA OnTheGo
Best phone app for AI-drafted JSAs with a risk matrix
JSA OnTheGo is a phone and tablet app just for JSAs, JHAs and JSEAs, from an Australian maker. Its AI drafts the risk assessment and PPE from the task details, or you start from a previous JSA or a company template. It has a risk matrix, photo markup and a geo-locator, assigns people to controls, and won't complete a JSA until everyone has signed; offline with a subscription. $0.99 a JSA, or $9.99 a month after a 7-day trial; companies pay A$10 a license a month, five or more.
Gadzoom
Best for USACE and NAVFAC Activity Hazard Analyses
Gadzoom is built for federal paperwork under the Army Corps of Engineers' EM 385-1-1. Pick an activity from thousands and the steps, hazards, controls and references fill in, in any of 46 languages. It prices by document with unlimited users: $149 for one AHA, $895 a year for 25, $2,795 unlimited. That's a lot for one crew's daily JHA, and the closest fit here for a federal job.
Safety Reports
Best dedicated JSA phone app
Safety Reports, part of AlignOps, has a phone app just for JSAs: type the tasks, pick hazards and controls from its lists or write your own, attach photos, collect signatures, work offline and get the JSA as a PDF by email. The app is a free download; the JSA module is listed in its Premium plan, priced by quote.
HCSS HeavyJob Safety
Best for heavy civil contractors already on HCSS
HCSS puts JHAs inside HeavyJob Safety: 100+ templates, severity, crew sign-off on a tablet, JHAs suggested from the cost code or equipment, multi-crew pre-task planning and offline recording, with 24/7 phone support. Priced by demo and quote.
Field1st
Best for AI-checked, risk-scored JHAs with many subs
Field1st goes furthest on the analysis. The crew talks through the job (English or Spanish, offline) or takes a photo; Field1st drafts the steps, scores each hazard by severity and likelihood and ranks the controls. A qualified person confirms and signs. Subs join by QR code with no seat cost. Quote only.
SiteDocs
Best for every worker's signatures and certifications
SiteDocs, part of Nemetschek, turns a company's safety forms into digital ones, with a login for every worker, unlimited forms and signatures, and each worker's signature and certification history. Annual subscription by company size, after a call.
HammerTech
Best for GCs reviewing subcontractors' JHAs
HammerTech is a general contractor's safety platform: one JHA library with high-risk tags, approvals and version history, plus daily pre-task plans with crew e-signatures that AI can fill from a recording. Subs use it free. It is priced on construction volume and, by its own account, isn't meant for very small teams or a single project.
How to choose
- Who writes it? A foreman at the tailgate needs a fast draft on a phone (Dozer, JSA OnTheGo, Field1st, Safety Reports); a safety manager needs a library, scoring and approvals (JSABuilder, HCSS, HammerTech).
- How often? A JHA every morning favors per-site or per-company pricing; a few dozen federal AHAs a year fit Gadzoom's per-document plans.
- How does the crew sign? One phone passed around (Dozer, JSA OnTheGo, HCSS on a tablet), a login per worker (SiteDocs), or a QR code for visiting subs (Field1st).
- Do you score risk? If your program or client wants risk scores, choose JSABuilder, JSA OnTheGo, HCSS or Field1st; Dozer has none.
- Where and in what language? Store apps for iPhone and Android: JSA OnTheGo, Mitti, Safety Reports (Dozer runs in a browser). Other languages: Gadzoom (46), HCSS (four), Field1st (Spanish voice). Dozer covers US federal OSHA only.

Questions
Does OSHA require a JHA?
Not as a general rule: OSHA 3071 is guidance. Some standards require a hazard assessment or inspection, such as the written PPE assessment in 29 CFR 1910.132(d) and daily trench inspections in 1926.651(k), and many GCs, owners and USACE contracts require a JHA. See Does OSHA require a JHA?
What are the 5 steps of a JSA?
Pick the job, break it into steps, name each step's hazards, set a control for each, then review it with the crew and sign. OSHA 3071 adds: involve the workers, start with the jobs that hurt people most, and review the JHA after an injury or illness.
Is there free JHA software?
Yes, with limits. Mitti is free for 10 users and 5 active templates; Dozer is free for one site, with AI drafts and crew sign-off; JSA OnTheGo sells single JSAs at $0.99; JSABuilder has a 30-day trial.
What's the difference between a JHA and a JSA?
None in practice: both break a task into steps, list the hazards and set controls. An AHA (activity hazard analysis) is the USACE version, and a pre-task plan is a shorter daily form for today's conditions. See JSA vs JHA.
Can AI write a JHA?
It can write a first draft: Field1st from voice and photos, HammerTech from recordings, JSA OnTheGo from the task details, Dozer from one sentence. None has seen your trench or your crew, so the competent person still walks the job, adds what's different and signs. See JHA builders.

- JSA vs JHA Two names for the same analysis, plus AHA, PTP, FLHA, JSEA, SWMS and RAMS, and where they really differ.
- How much JHA software costs Per user, per seat, per AHA and per site, with the yearly sums for three kinds of contractor.
How we checked
On November 13, 2026 we read each tool's pricing page, JHA page and app store listing. Where a maker doesn't say, the table says "Not stated". We didn't score or star-rate anyone, or sign up for the quote-only platforms. If something here is wrong, write to support@winding.ai.
About this page
This page is published by Winding AI, Inc., the company that makes Dozer, one of the ten tools compared here. We wrote it because the top results for this search are mostly directory listings that don't say how the crew signs or what a year costs. We earn nothing from links to other tools; links to Dozer carry a tag so Dozer can count visits from this page. Visits are counted with Google Analytics, and there are no ads.
