Source approach
We prefer primary, official and manufacturer sources for requirements and technical specifications.
- OSHA — Workplace safety information and standards in the United States.
- CCOHS — Canadian occupational health and safety guidance.
- UK Health and Safety Executive — Workplace safety guidance in Great Britain.
- Product manufacturers and SDS — Product labels, safety data sheets and equipment instructions take priority for specific products and methods.
Local requirements
Requirements can change by jurisdiction and over time. Verify current law, codes, permits, contracts, workplace procedures and manufacturer documentation before acting on safety-critical or regulated questions.
