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.

Thermographic Survey & Inspection Ontario

Infrared thermographic surveys for electrical systems, building envelopes, and mechanical equipment, identifying thermal anomalies before they become failures.

How often should electrical thermographic surveys be done?

NFPA 70B recommends annual thermographic surveys for electrical distribution systems. High-criticality facilities (hospitals, data centers, continuous process) may survey semi-annually. Insurance carriers often require annual surveys as a condition of coverage.

Key Deliverables

Thermographic survey report
Annotated thermal images with analysis
Severity classification (priority 1-4)
Comparison with visible-light photographs
Electrical panel / switchgear scan results

What load conditions are needed for accurate results?

Electrical equipment should be operating at a minimum of 40% of rated load for meaningful thermographic results. Higher loads produce larger temperature differentials, making anomalies easier to detect. Schedule surveys during peak production periods.
