Risk Assessment Insulation — Dust, Skin & Isocyanates Skip to content

Risk Assessment for Insulation — create with RAMSagent

A risk assessment for insulation evaluates project-wide risks during the installation of mineral wool, foam plastic, or spray insulation. It covers dust, skin, falls during roof work, and isocyanates from PU foam according to Canada Labour Code Part II and COHSR.

RAMSagent selects protection level and permits per insulation material and application method.

Typical risks for Risk Assessment — Insulation

Risks, description, and applicable legislation
Risk Description Legal Severity
Isocyanates in PU Spray Insulation Spray-based PU foam requires permits, medical surveillance, and supplied-air respirators. Evacuation time is 24 hours for non-participating personnel. Canada Labour Code Part II; COHSR Critical
Falls Through Roof/Attic Loose insulation in attics conceals joists. Walkways or temporary roofs are required before anyone can enter the attic space. Canada Labour Code Part II; COHSR Critical
Inhalation of Mineral Wool Prolonged exposure to glass and stone wool dust requires FFP2–FFP3 masks and mechanical ventilation in enclosed attics. Canada Labour Code Part II; COHSR Medium
Skin Irritation Fibres from mineral wool cause itching and rashes. Work clothes should be changed before going home to reduce secondary exposure. Canada Labour Code Part II; COHSR Medium
Canada Labour Code Part II Occupational Health and Safety Management
Systematic occupational health and safety management.
Canada Labour Code Part II Chemical Workplace Hazards
Part II (dust) and Part II (isocyanates).
Canada Labour Code Part II Medical Surveillance
Requirements for medical surveillance for isocyanate exposure.

Frequently Asked Questions

What does a PU permit cost?
The permit application with the Labour Inspectorate is formally free, but requires documented training, medical surveillance, and work routines — RAMSagent helps gather the necessary documentation.
Can you switch from PU to mineral wool?
Often — mineral wool provides equivalent U-value with significantly lower health impact. The Job Hazard Analysis (JHA) should evaluate the alternative.
