Resin and Epoxy Floor Application Safety
Resin and epoxy floor coatings are applied in industrial buildings, commercial kitchens, car parks, and clean rooms. The mixing and application process releases volatile organic compounds and sensitising chemicals, particularly isocyanates in polyurethane systems. Operatives face respiratory sensitisation, skin irritation, and fire risk from flammable solvents. This talk covers the safety controls for resin floor application on UK construction sites.
Key Hazards
Respiratory sensitisation from isocyanate exposure in polyurethane systems
Skin irritation and dermatitis from direct contact with uncured resin
Flammable vapour accumulation in enclosed spaces during application
Slips on freshly applied wet resin surfaces during the coating process
Control Measures
- Review the COSHH assessment and safety data sheet for every resin product before mixing.
- Provide forced-air ventilation in enclosed areas to maintain vapour levels below the WEL.
- Wear chemical-resistant gloves, coveralls, and safety glasses during all mixing and application.
- Use RPE with an organic vapour filter or air-supplied respirator as specified in the COSHH assessment.
- Eliminate ignition sources in the application area and use ATEX-rated electrical equipment.
- Apply the resin in sections, maintaining a clear escape route to the exit at all times.
- Display wet floor warning signs and barriers around the application area during curing.
- Ensure health surveillance is in place for all workers regularly exposed to isocyanate products.
- Brief all nearby workers on the application schedule and the need to stay out of the area.
Remember
- Read the COSHH assessment and safety data sheet before mixing any resin product
- Wear chemical-resistant gloves, coveralls, and the RPE specified in the assessment
- Maintain ventilation and eliminate all ignition sources in the application area
- Always maintain a clear escape route to the exit during application in enclosed spaces
- Health surveillance is required for workers regularly exposed to isocyanate-based products
Applicable Legislation: COSHH 2002 · DSEAR 2002 · EH40 Workplace Exposure Limits · Health and Safety at Work etc. Act 1974
