Using a spray booth when spraying paint reduces exposure to harmful vapours and reduces the risk of fire and explosion. The Environmental Protection Agency issues permits to paint spray booth operators that follow the necessary safety rules and operators must obtain a permit in order to legally operate a paint spray booth.
The Environmental Protection Agency states that paint spray booths should use filters that remove at least 90 per cent of the particles found in the booth's exhaust stream. Filters must be changed regularly so they remain clean and functioning at full capacity. Readings from a magnehelic pressure gauge indicate how often filters need to be changed.
Personal Protective Equipment
Workers should always wear the appropriate personal protective equipment when working in a paint spray booth or changing filters. Personal protective equipment includes full face or half face respirators, gloves and coveralls.
If filters contain hazardous waste, the EPA requires they be disposed of in specific ways, depending on the type of waste present. Some filters contain hazardous waste particles while others do not, so workers should check with the manufacturer or local authorities to determine the proper way to dispose of filters.
