HSE 261 recommends that a smoke clearance testing is carrid out 14 mothly along with yor LEV COSHH test (we also offer this service)
Using professional smoke machines, we can carry out the smoke test efficiently and supply you with the pass certificates.
The Smoke Testing Process:
Extraction off - Lights on Smoke machine on 2 minutes... Smoke machine off - White out Start extraction & timer Inspect seals & ducting for leakage Smoke clear - Test complete Certicate for display
Smoke is most likely to linger and form eddies close to all the walls of a downdraft spray booth; in a room, the smoke will mix with the air and dilute evenly.
By disabling the extraction before filling the room with smoke a maximum clearance time is measured. As the extraction is usually running during normal spraying operations, the clearance time may be less than this but as a safety margin, it is important that the maximum time is observed.

"Carole was always my first choice person to contact because she understood her products, and achieved our correct supply requirements on schedule. It was also nice to talk to Carole, she really brightened up the day."
Deborah Woods, Design Draughtsperson & Project Engineer
"I had several interactions with Carole with regards to the potential supply of filter cartridges to my company. I not only found Carole to be very enthusiastic and technically good during the specification process but also exceedingly good and persistent at the often neglected follow up stuff. I look forward to doing further business with Carole in the future."
Clyde Process, Filtration Sales Manager
"By switching to C-Air, I saved over £50.00 per filter."
