September 2010 - Bodyshop workers occupational asthma risk
Almost all bodyshops will use paints containing an isocyanate hardener. Isocyanates are also found in some water-based paints and almost all lacquers.
Breathing in isocyanate paint mist can cause asthma; the HSE estimate that vehicle paint sprayers are about 80 times more likely to develop occupational asthma than the average worker.
A recent survey found that the vast majority of sprayers (85%) do wear air-fed breathing apparatus. However, many continue to put their health at risk by lifting their visors to check the finish before the paint is dry, potentially exposing themselves to the isocyanate-containing mist.
The survey also found that many sprayers are still unaware of the dangers of invisible spray mist and almost one in five bodyshop managers did not know their booth clearance times. This puts workers at risk of re-entering booths too soon, making them more vulnerable to breathing in isocyanates.
The main source of isocyanate exposure is paint spraying, it can also occur when cleaning the spray gun.
The risk of exposure and developing asthma can be controlled by:
- Only spraying in properly designed spray booths and rooms;
- Knowing the clearance time for the booth and following correct working procedures;
- Ensuring that sprayers always wear air-fed breathing apparatus;
- Providing regular health surveillance for anyone exposed to isocyanates; and
- Carrying out regular checks to confirm that the controls are working properly.
