Is a CSP legally required in Ontario?

Under the OHSA and O.Reg. 213/91 (Construction Projects), the constructor must ensure a safety program is in place. While the regulation does not prescribe a specific document format, a written CSP is the standard of practice to demonstrate due diligence and is required for COR certification.

How often should a CSP be updated?

The CSP should be treated as a living document. Update it whenever a new trade mobilizes, a significant hazard is introduced, or after any serious incident. At minimum, review monthly on active projects.

Can one CSP cover multiple projects?

A generic template can serve as a starting point, but each project must have a site-specific CSP addressing the unique hazards, trades, site layout, and emergency procedures for that location. A copy-paste approach fails audits.

What standard governs LOTO in Ontario?

O.Reg. 851 (Industrial Establishments) s.75 requires measures to prevent equipment startup during maintenance. CSA Z460 "Control of Hazardous Energy" is the referenced standard of practice. Federally regulated workplaces follow Canada Labour Code Part II.

How often must LOTO procedures be audited?

CSA Z460 requires at least an annual audit of the LOTO program. Each procedure should be observed at least once per year. Any equipment modification, incident, or near-miss involving energy isolation should trigger an immediate review.

Noise Assessment & Dosimetry Ontario

Occupational noise surveys, dosimetry, engineering control recommendations, and hearing conservation programs meeting O.Reg. 381/15 and CSA Z107 requirements.

What is the noise exposure limit in Ontario?

O.Reg. 381/15 sets the occupational exposure limit (OEL) at 85 dBA Lex,8h (8-hour equivalent continuous sound level) with a 3 dB exchange rate. Peak sound levels must not exceed 140 dBC. Employers must take reasonable measures to reduce exposure below the OEL.

What is the difference between area and personal monitoring?

Area monitoring (sound level meter on a tripod) measures the noise environment at a location. Personal monitoring (dosimeter worn by the worker) measures the actual exposure received by a specific worker throughout their shift. Both are needed for a complete assessment.
