FAQ
Common questions.
Are these tools free?
Yes. Every workplace safety tool on this page is free forever — no sign-up, no paywall, no ads inside the tools. Use them on your phone, tablet, or desktop from the job site or office.
What regulations do these tools cover?
The tools reference the Occupational Health and Safety Act (OHSA), the Workplace Safety and Insurance Act (WSIA), O. Reg. 213/91 (Construction Projects), O. Reg. 632/05 (Confined Spaces), O. Reg. 381/15 (Noise), O. Reg. 860 (WHMIS), O. Reg. 1101 (First Aid), O. Reg. 834 (Critical Injury Definition), and related Ontario regulations. Each tool cites the exact section it draws from.
Who verified these tools?
The tools are verified by a Red Seal Carpenter with direct experience on Ontario construction sites. Every tool shows the verification date in its footer. The regulatory references are traced to specific sections of the applicable Ontario statute or regulation.
Can I use these for a Ministry of Labour inspection?
The tools cover the most commonly cited inspection items — fall protection, scaffolding, PPE, signage, JHSC compliance, first aid, and confined space. Running through the relevant checklists before an inspector visits will help you identify and fix gaps. The branded PDF printouts document your compliance efforts with regulation citations.
How do I calculate my WSIB premium?
Use the WSIB Premium Calculator. Enter your number of workers, average salary, and select your NAICS industry code (or use the NAICS lookup to find it). The calculator applies the 2025 premium rate and shows your estimated annual premium, monthly payment, and per-worker cost.
Do these tools replace a health and safety consultant?
No. The tools reproduce regulatory requirements from Ontario statutes for common workplace situations. Complex sites, unusual hazards, or legal proceedings require professional advice. The tools flag when a situation exceeds their scope.
Are these tools Ontario-specific?
Yes. WSIB, OHSA, and the cited Ontario Regulations apply to Ontario workplaces. Other provinces have their own legislation. General safety principles are similar across Canada, but specific legal requirements vary by jurisdiction.
Does ToolFluency have other construction tools?
Yes. The Ontario Building Code suite has 24 free calculators for residential construction — framing spans, beam sizing, stair geometry, egress windows, footing depth, and more. Plus 200+ other free tools covering finance, business, health, kids, music, and more. Browse everything →
