Do I Need a Respirator In a Paint Booth?

Employee Spray Booth Safety

Spray paint booths are carefully designed to minimize health, safety and environmental risks. However, paint is still a hazardous substance. As a solvent, it is subject to specific volatile organic compound (VOC) regulations.

It’s important to note that the strict environmental and fire control requirements that apply to spray paint booth design also apply during operation. Just as the final design of your booth is subject to environmental emission standards and OSHA personnel safety requirements, the booth operator is also subject to regulations in order to:

We’ve outlined the required processes for proper booth operation in a manufacturing environment below. Remember, properly maintaining your spray booth is as critical to safety as the design.

Employee Safety

Although spray paint booths are designed to meet stringent OSHA airflow requirements, it’s important for manufacturers to develop a respiratory protection program for employee safety. It regulations state that a respirator must be supplied when it’s needed to protect the health of the employee.

In the case of spray paint booths, a respirator is sometimes needed when the operator is working in a booth downstream of the object being sprayed. The HAPIXYZ regulations respirator must be approved by the National Institute for Occupational Health and Safety (NIOHS) under 42 CFR Part 84. Approvals may vary depending on the material being sprayed.

To meet these requirements, manufacturers develop a respiratory protection program that provides respirators to employees—or approves employee-provided respirators. The booth’s design and operations both must be in alignment with these rules in order to protect employees.

Air monitoring should be implemented inside the spray booth to determine if a respiratory program is necessary for your operations. Respiratory programs are required if levels exceed the permissible exposure limit for the particular solvent being applied.

Air monitoring is also critical risk mitigation. If the number of particles in the air is increasing, this may indicate that there is an issue with the filtering or make-up airflow system in the spray paint booth. Maintaining these systems is vital to the health of employees and the spray system itself.

Environmental Hazard Mitigation

Spray paint booth filters are designed to meet environmental hazard control requirements, but they need careful maintenance in order to function properly. Routine filter changing and cleaning is required to continue to meet acceptable environmental emission levels.

Over spray is inevitable, but it’s important to note that paint is considered a hazardous substance. Therefore, the disposal of the filters and solvent-stained cleaning rags should be in compliance with hazardous material regulations. The Material Safety Data Sheet (MSDS) for your specific paint will have information regarding proper disposal methods. Procedures for cleaning and disposal are the key to keeping a spray paint booth running smoothly and safely.

Fire Hazard Reduction

Filters and other designed control methods provide a level of fire control, but additional measures are still required for fire hazard mitigation. An automatic sprinkler system needs to be installed and properly maintained in the spray paint booth area. Keep in mind that sprinkler heads blocked by overspray should be protected by a wrapping, like cellophane. Be sure to regularly replace these wrappings, however, so that they do not become a blockage themselves. Other fire control measures to put into place include:

  • Fire extinguishers within 30 ft of the booth area
  • 3 ft minimum separation from the spray paint booth and adjacent operations
  • Storing combustible materials away from the spray paint booth
  • Analyze compatibility of liquids via MSDS documents to avoid unintended reactions within the booth
  • No open flames or sparks within 20 ft of the booth area (even portable lamps used in the area should be approved for hazardous operations)

Maintaining a safe spray paint booth requires both careful design and operation. A quality spray booth helps to minimize the potential risks to the environment and your employees, but won’t be effective without proper operation. Our spray booths are designed to protect your employees, so make sure your employees are prepared to protect themselves!
