Urine sampling for isocyanate exposure measurement
26 August 2008, News release from Air Quality Assurance
Air Quality Assurance are now offering Urine sample testing for Isocyanate derivatives.
Urine testing is recommended to assess exposure to isocyanate and the effectiveness of controls such as respiratory protective equipment (RPE) and safe working procedures.
It supplements air sampling, which assesses the effectiveness of mechanical controls. Testing works by measuring the breakdown products of isocyanate in urine.
This means taking samples of urine from workers that may have breathed in spray or vapour, and from unprotected workers nearby. Urine samples may be taken once or twice a year, unless it is clear from results that exposure is not happening.
Companies with good control practices - which includes training and instruction of workers - can get isocyanate exposures down to very low levels. Urine testing is a sure way to check that workers' exposures are properly controlled. If not, the control measures may not be working properly. The action is to investigate how or why the controls were ineffective, and remedy them.
We are suppliers of air fed respirators both full face and half mask, reusable 1/2 masks and 1 shift disposable mask.
