Spray Finishing Using Flammable Materials

Understanding This Standard

OSHA Standard 1910.107, 'Spray finishing using flammable and combustible materials,' sets forth critical safety requirements for operations involving the spray application of paints, coatings, and other materials containing flammable or combustible liquids. This standard is crucial for preventing fires, explosions, and exposure to hazardous substances in workplaces utilizing spray booths, spray rooms, and other spray finishing areas.

The standard covers various aspects, including the design and construction of spray booths and rooms, ventilation systems, electrical equipment, storage of flammable liquids, fire protection, and employee training. Key requirements include ensuring adequate ventilation to prevent the accumulation of flammable vapors, using explosion-proof electrical equipment where flammable vapors may be present, and providing proper fire suppression systems.

Common violations of 1910.107 often stem from inadequate ventilation, which can lead to dangerous concentrations of flammable vapors. Other frequent issues include non-compliant electrical installations (e.g., using standard electrical outlets or lights in hazardous locations), improper storage of flammable liquids within or near spray areas, lack of proper grounding and bonding to prevent static electricity discharge, and failure to maintain spray booth filters, leading to reduced airflow and increased fire risk. Furthermore, employers often neglect to conduct regular inspections and maintenance of spray finishing equipment or provide adequate training to employees on safe operating procedures and emergency protocols.

Penalties for violating 1910.107 can range significantly, with an average penalty of $182, but a maximum single penalty can reach $70,000 for serious, willful, or repeat violations. The severity of the penalty depends on factors such as the nature of the violation, the employer's history, and the potential for serious injury or death.

To comply with 1910.107, employers must ensure that all spray finishing operations are conducted in approved spray booths or rooms equipped with effective mechanical ventilation systems. All electrical wiring and equipment within these areas must meet Class I, Division 1 or 2 hazardous location requirements, as appropriate. Flammable and combustible liquids should be stored in approved containers and storage cabinets, and only minimal quantities should be present in the spray area. Proper grounding and bonding of all equipment must be maintained to prevent static electricity. Employers must also implement written safety procedures, provide fire extinguishing equipment, and ensure all employees involved in spray finishing operations receive comprehensive training on the hazards, safe work practices, and emergency procedures.
