Free Safety Tools — Calculators, Selectors & Checklists

Free safety tools only earn a bookmark if they cite their method — this hub indexes all 26 free calculators, selectors, checklists and data references on WC Safety — built for safety managers, contractors and EHS teams, nothing gated behind an email. The gear they point at lives on workplace PPE.

Which free safety tools are in the toolbox?

Short answer: six families — hearing and noise (NRR, dose, exposure), respiratory (cartridge selector, silica Table 1), PPE selection (hazard assessment, cut levels, glove chemical compatibility and sizing, hi-vis class), site work (fall clearance, ladder angle, welding shade, heat stress), housekeeping (spill kit and trash liner sizing, standards converter) and inspections (forklift, LOTO, confined space, eyewash), plus compliance data — the TRIR & DART benchmark calculator, the OSHA recordable-injury screening tree, the FY2025 citation explorer and the FY2025 PPE violation report.

Free, no-signup tools for safety managers, contractors and EHS teams — most apply a published OSHA, NIOSH or ANSI/ISEA method, with the standard cited on the tool page. Nothing is gated behind an email.

How the toolbox fits together

Start where the duties start: the PPE hazard assessment builder maps the workplace, the NRR calculator derates the hearing answer, the heat index calculator bands summer work, and the welding shade chart covers the hot-work corner. The compliance chain runs through the new tools: the recordability decision tree screens what belongs on the 300 log, the TRIR & DART calculator benchmarks the resulting 300A against BLS industry averages, and the citation explorer shows what OSHA actually cited last fiscal year. The PPE deep-dive lives in the FY2025 violation report.

Our methodology

Each tool page names the standard or method it implements (OSHA, NIOSH or ANSI/ISEA where one exists — the glove sizing guide uses plain hand-measurement conventions) and carries its own scope caveats; this hub only indexes them and links every card to the live page. Authoritative duties live at OSHA regulations and exposure science at NIOSH. We hold no safety certification, and this tool is not a substitute for professional judgment.

Why trust this page

WC Safety is an independent review site with no products of its own — nothing here is stocked, warehoused or shipped by us. Purchase links go to Amazon and earn an affiliate commission at no extra cost to you. This free tool is informational — it supports, and never replaces, a written program, a hazard assessment, or evaluation by a qualified safety professional.

Frequently Asked Questions

Are these safety calculators really free?

Yes — no signup, no gating, no export fee. The site earns from Amazon affiliate links on product reviews, which keeps the tools free.

Do the tools satisfy OSHA documentation duties?

They produce the working content — a printed hazard assessment still needs workplace, assessor and date; a noise screen never replaces dosimetry. Each page states what remains yours.

Which tool should a new safety manager start with?

The ppe hazard assessment builder — it maps the workplace, and its output points into the rest: the nrr calculator for noise findings, the heat index calculator before summer pours, the silica Table 1 lookup for concrete work.

How current are the osha compliance tools?

Tool logic states its source standard and revision; the FY2025 violation report carries its retrieval dates, and pages show their last-reviewed date at each footer.

Can I link or embed these tools?

Linking is welcome — that is how free tools stay free. The pages are not embeddable as iframes; link the card URL instead.

A tool is missing — can I request one?

Yes — the contact page takes requests, and several tools here (the trash liner calculator among them) started as reader asks.
