NFPA-33 Standard for Spray Application of Flammable or Combustible Materials states:
Spray areas, which include by definition any associated exhaust plenums and exhaust ductwork, (and all associated equipment and areas) shall be protected with an approved automatic fire protection system.
This typically means that a spray booth will have a dry chemical system installed that:
– has automatically actuated ‘flags’ that set off the system if a fire develops in the booth, exhaust plenum, or exhaust ductwork
– has a audible alarm system if the system is actuated
– performs emergency shutdowns as required by the paint booth system design
– is designed and made by a certified manufacturer
– is installed by licensed contractors
– is inspected by a licensed inspector on a specified basis.
Most systems are solvent-based spray booths and powder coat spray booths are dry chemical units much like those used in restaurants. Some applications and localities may require wet sprinkler systems.
You should be able to find licensed contractors in your area, or you can call our sales or engineering staff for further help.
