Isocyanate Exposure: Protecting Your Spray Foam Crew (and Your Business)
April 28, 2026

Every spray foam contractor knows the smell of a fresh application, but the more important thing to understand is what's in the air. Isocyanates—a key component of polyurethane foam—are the defining occupational hazard of the trade, and managing that risk protects both your crew and your business.
What Makes Isocyanates a Concern
Isocyanates are reactive chemicals used in the A-side of two-component spray foam. Exposure—through inhalation or skin contact—can cause respiratory sensitization and other health effects, particularly with repeated unprotected exposure. That's why proper respiratory protection, ventilation, and skin protection are central to safe foam application.
Protecting Your Crew
A strong safety program is the first line of defence: supplied-air or appropriate respirators during application, full skin and eye protection, adequate ventilation, enforced re-entry times, and documented training on isocyanate handling. These practices reduce injuries—and insurers reward documented safety programs with better terms.
Where Workers' Coverage Comes In
In Canada, mandatory workers' compensation is administered provincially (WCB, WSIB, and equivalents) and covers on-the-job injury. But the right program goes further: employers' liability coverage protects your business when a claim extends beyond the board's scope, and correct classification ensures your premiums reflect the actual SPF work your crew performs.
Why Classification Matters
Workers' coverage rates depend on how the work is classified. Misclassified spray foam work can mean either overpaying or, worse, a coverage dispute when an injured worker's actual duties don't match the classification on file. An agency that understands SPF makes sure the classification is right from the start.
The Business Case for Safety
Beyond protecting people, a documented safety and respiratory-protection program lowers claim frequency, improves your experience rating over time, and earns credits at renewal. Safety isn't just compliance—it's one of the most effective ways to control your insurance cost.
