Fires and explosions are among the principal hazards which can result from improper operation and maintenance of spray booths. Contributing factors include:

  • Insufficient operation and maintenance of the exhaust systems
  • Excessive accumulations of particulate and over-spray
  • Chemical imbalance
  • Improper operation of the burner
  • Improper filter maintenance.

Forbidden Spray Booth Acts

The following actions must be avoided:

  • Mixing, preparing and/or storing any solvents inside the spray booth
  • Storing any solvent soiled rags, cardboard, or other debris inside the spray booth
  • Storing solvent containers (even empty containers) inside the spray booth
  • Storing any flammable substance such as aerosol spray cans

  • Regularly clean and maintain all parts that are subject to wear
  • Clean ductwork based on the manufacturer’s recommendations
  • Maintain tools and accessories, such as air compressors,  per the manufactures recommendations
  • Develop a housekeeping and maintenance schedule
