Smoke Clearance Time
Refinishing Technologies carry out a Smoke Clearance Test on request.
Recent HSE guidelines recommend for Vehicle Bodyshop Owners to have regular smoke clearance time undertaken to control the risks and exposure to harmful substances to their spray painters. (recommended testing during annual service or every 14 months)
The test carried out will determine the amount of time it will take for harmful materials such as isocyanates to be fully evacuated from spraybooth once spray painting has been completed. Even though a painter may have stopped applying product to the vehicle there will still remain quantities of harmful materials in the air until the spraybooth has been fully evacuated.
During this time the protective mask or full face breathable mask should not be removed. As mentioned above, the purpose of this test is to measure the time it takes for isocyanate particles to be cleared from the spraybooth.
