Attention: TDR Forum Junkies I suspect the price of bedliners will dramatically increase shortly:
OSHA Studies Spray-On
Truck Bedliners
WASHINGTON - Concerned about adverse human health affects of exposure to methylene bisphenyl isocyanate (MDI), the U. S. Occupational Safety and Health Administration (OSHA) recently completed an investigation of auto body repair and refinishing businesses that apply spray-on truck liners.
The investigation found that as many as 46 percent of the businesses investigated do not meet the Agency's "permissible exposure limit of 0. 2 milligrams per cubic meter of air for MDI. " However, OSHA also concluded that with the implementation of simple and minimal measures, the amount of exposure to MDI can be reduced significantly by these shops.
The suggested measures include:
* Conducting all spray operations inside a ventilated paint spray booth.
* Maintaining air velocities at a minimum of 100 feet per minute in the booth.
* Utilizing local exhaust ventilation when spraying in dead air spaces.
* Keeping operators outside of the truck bed during spraying.
* Using a spray extension handle to keep nozzle away from the breathing zone.
* Setting the spray pressure and temperature to the minimum level needed.
* Wearing a face shield or goggles when the half mask respirators are used.
* Wearing gloves and coveralls when prepping, spraying and cleaning up.
* Using tools such as spatulas when mixing the materials.
