Spray Finishing and Flammable Material Safety

The regulation mandates that your employer maintain safe environments for spray finishing operations involving flammable or combustible materials. You must be provided with specialized spray booths to confine vapors and residues, ensuring they are directed away from you through proper exhaust systems. Your employer must also manage ignition sources and maintain strict cleanliness to prevent the buildup of hazardous materials.

Under 1910.107(b), spray booths must be constructed of noncombustible materials and kept free of residue. Ventilation requirements in 1910.107(d) dictate that air must be exhausted to the exterior to prevent vapor accumulation. Additionally, 1910.107(c) prohibits open flames or spark-producing equipment within 20 feet of any spraying area to minimize your risk of fire or explosion.

This standard applies to any workplace where you apply flammable or combustible coatings via spraying. It is critical for industries such as automotive repair, furniture manufacturing, and industrial painting. If you work in or near a spray booth, including as a painter, maintenance staff, or shop floor worker, you are covered by these safety requirements.

OSHA frequently cites employers for failing to maintain adequate ventilation or allowing combustible residue to accumulate in your spray areas. Violations of 1910.107(g)(2) regarding daily cleaning are common, as are failures to use explosion-proof electrical equipment as required by 1910.107(c)(6). These lapses often stem from a lack of proper maintenance or inadequate safety training.

In practice, these violations look like spray booths clogged with layers of dried paint or the use of non-approved electrical tools near flammable vapors. You may see managers bypassing safety interlocks on exhaust fans to save on electricity or failing to provide proper metal waste cans for solvent-soaked rags. These conditions create an immediate risk of fire or chemical exposure. An attorney can help you determine if your employer's safety failures contributed to your injury.

OSHA classifies violations of this standard as serious, particularly when fire hazards are present. Fines can reach thousands of dollars per violation, and repeat offenses often lead to significantly higher penalties. Inspections are frequently triggered by your complaints regarding poor air quality or following a fire or explosion incident. Employers who ignore these rules face both regulatory fines and potential liability for your injuries.

You have the right to a workplace free from recognized fire and explosion hazards. If you believe your spray booth is unsafe or lacks proper ventilation, you can file an anonymous complaint with OSHA. Under Section 11(c) of the OSH Act, your employer is prohibited from retaliating against you for reporting safety concerns or participating in an inspection.

If you are injured in a fire or explosion related to spray finishing, document the conditions immediately. Take photos of the booth, note any missing safety equipment, and report the incident to your supervisor. Because these cases often involve complex liability issues, an attorney can help you ensure your rights are protected and your Workers' Compensation claim is handled correctly.
