Example: Spray painting with isocyanate-based two-pack top coat
Isocyanate can cause asthma. You must reduce exposure to isocyanate as far below the WEL of 0.02 mg/m3 (8 hours) and 0.07 mg/m3 (15 minutes) as reasonably practicable. You normally need to use health surveillance.
Isocyanate can also cause dermatitis.
Control measures include:
- enclosed, extracted spray booth marked with its clearance time;
- air-line respiratory protective equipment;
- other personal protective equipment;
- health surveillance for asthma and skin checks.
Help in identifying the right controls is on the MVR COSHH essentials web page. Control information for isocyanate appears in:
- MR1 Mixing two-pack paint, etc;
- MR2 Spraying two-pack products in a spray/bake booth;
- MR3 Cleaning two-pack spray guns;
- MR4 Brush or roller application of two-pack products;
- MR5 Flatting, SMART repair, welding, etc.
