Free EHS tools
Six free tools EHS managers actually use.
No login. No email required. No "free trial that turns into a sales call." These six tools handle the questions an EHS team faces every week — is this case recordable, where do I report it, what's my year-end TRIR, does my chemical inventory trigger Tier II, how do the same questions play out in the Netherlands or the UK. Same rules SE runs continuously for paying customers; the free versions are the one-shot walkthroughs.
US · OSHA 1904.7
Is this case OSHA recordable?

How they work
Same rules SE runs for paying customers.
Every recordability walkthrough on this page is the same C# cascade SE evaluates against every customer incident — with the per-state-plan deviations applied, the right form auto-rendered, and the reporting clocks counting down against actual outcomes. A drift-gate test prevents the free-tool JS from diverging from the in-product C#.
Your inputs never leave the browser. There's no analytics tracking on the verdicts, no email collection by default, no "let us call you about your TRIR." The optional "email me this result" form on the recordability walkthrough is a single opt-in — deliberate, not gated.
For integrators: the OSHA 1904.7 cascade is also a public REST API at POST /tools/recordability — same shape as the JS walkthrough, rate-limited 60 calls per hour per IP. Documentation lives on the tool's page; programmatic integrators (insurers, BLS-survey software, third-party EHS platforms) call it directly.
Want this continuously, not once?
The free tools handle one case, one chemical, one year-end roll-up at a time. SE runs all six rules continuously against every customer incident + every chemical inventory entry + every year-end roll-up, with the right form auto-generated, the reporting clocks tracking against actual deadlines, and the audit trail attached to every decision.
