Understanding OSHA 1910.107

OSHA 1910.107 is the specific standard governing spray finishing using flammable and combustible materials. This regulation incorporates NFPA 33 by reference and adds OSHA-specific requirements for worker protection. Understanding 1910.107 is essential for maintaining compliant spray operations.

Non-Compliance Penalties

Violations of 1910.107 can result in OSHA citations with penalties up to $15,625 per serious violation and $156,259 per willful violation. Repeat violations and failure to correct carry enhanced penalties.

2

Spray Booth Construction

Spray booths must meet specific construction requirements:

  • Metal, masonry, or other noncombustible materials
  • Adequate structural strength
  • Smooth interior surfaces for easy cleaning
  • Adequate illumination with proper electrical classification
3

Ventilation Requirements

1910.107 specifies ventilation requirements:

  • Maintain atmosphere below 25% of lower flammable limit
  • Minimum 100 fpm average air velocity at face of booth
  • Exhaust ducts must lead to exterior
  • Interlock exhaust with spray equipment
4

Electrical & Fire Requirements

Electrical and fire protection requirements include:

  • Electrical equipment rated for classified locations
  • Adequate fire protection per NFPA 33
  • No open flames or spark-producing equipment
  • Grounding of spray equipment and objects

OSHA 1910.107 Compliance FAQ

1910.107 incorporates NFPA 33 by reference for many requirements but adds OSHA-specific provisions. Meeting NFPA 33 typically satisfies the related parts of 1910.107, but both standards should be reviewed.
The fire safety provisions apply based on the materials sprayed. Waterborne paints with low flammability may have reduced fire hazard requirements, but ventilation for health protection still applies.
The Lower Flammable Limit (LFL) is the minimum concentration of vapor in air that will burn. 1910.107 requires ventilation to maintain concentrations below 25% of LFL - a significant safety margin.
Documentation of booth construction, ventilation testing, electrical classification, fire protection, and maintenance demonstrates compliance. WERCS inspection reports provide third-party verification.
