Wear personal protective equipment to avoid over exposure from MDI
When cleaning truck bed lining equipment, it is recommended that such personal protective equipment (PPE) as safety glasses or splash goggles, MDI-resistant chemical gloves, long-sleeve coveralls and safety boots be worn.

Additional protection is needed when spraying a truck bed liner system. Personal protective equipment, such as splash goggles, MDI-resistant long-sleeve coveralls or full body suits with a hood, and MDI-resistant fitted boots and booties, will help protect from exposure. Respiratory protection, in the form of an approved supplied air respirator (as outlined in most company’s Respiratory Protection Program) also is needed. 

Engineering controls and ventilation
To further minimize exposure to MDI in the truck bed liner industry, appropriate ventilation, combined with a properly designed spray enclosure, is needed.  The use of a ventilated enclosure helps to contain spray mists and vapors that develop during truck bed liner application process. Further, exhaust filters and stacks help to capture the spray mists, which reduce the potential for exposure to those outside the building. 

It is recommended that a preventative maintenance program for the ventilation system be established to ensure that all of the components of the system (filters, airflow, etc.) are maintained properly.

A truck bed liner should not be sprayed until the ventilation system is operating properly and the appropriate amount of personal protective equipment is worn.

Did You Know?

Did you know that material data safety sheet (MSDS) is made available by the spray polyurethane foam (SPF) supplier. An MSDS provides important information about the chemicals associated with applying spray polyurethane foam and describes first-aid procedures in the event of accidental exposure.
