Potential Hazard

Fire and explosion hazards associated with paint and coating applications depend upon the flashpoint and volatility of the substance. Lower flashpoint liquids (less than 80º F) present greater hazards and require additional controls.

Requirements and Example Solutions

The following control requirements and hazard solutions have been separated into two categories:

1. Liquids/substances with flashpoints above 80º F
2. Liquids/substances with flashpoints below 80º F

 

Liquids/substances with flashpoints 80º F and above

• Hot work must not be performed in the space or adjacent spaces during painting operations. [29 CFR 1915.36(a)(1)]
• Rags soaked with solvents must be kept in covered metal containers. [29 CFR 1915.36(a)(3) and 29 CFR 1915.81(a)(5)]
• Paints, thinners, and solvents must be kept in fire-resistant covered containers when not in use. [29 CFR 1915.81(a)(5)]

• 30-gallon drums and containers of flammable or toxic liquids must be placed in an area where they will not be subject to physical damage. [29 CFR 1915.173(d)]
• 55-gallon drums containing flammable or toxic liquids must be surrounded by dikes or pans. [29 CFR 1915.173(e)]
• Power and lighting cables must be inspected by a person competent to evaluate electrical hazards and ensure there are no connections within 50 feet of the painting operations (not necessarily the Shipyard Competent Person). [29 CFR 1915.36(a)(5)]
• Spills of solvents should be cleaned up immediately.

 

 

Liquids/substances with flashpoints below 80º F

When paints and tank coatings are dissolved in highly volatile, flammable solvents with flash points below 80º F, the following additional precautions must be taken:

• Sufficient exhaust ventilation must be provided to keep the concentration of solvent vapors below 10 percent of the lower explosive limit (LEL). Frequent tests must be made by a competent person to ascertain concentrations. [29 CFR 1915.35(b)(1)]
• If the concentration exceeds 10 percent of the LEL, work must be stopped until the concentration falls below 10 percent of the LEL. [29 CFR 1915.35(b)(2)]
• Ventilation must be continued after painting is complete until the space or compartment is "gas-free." [29 CFR 1915.35(b)(3)]
• Exhaust ducts must discharge clear of working areas and away from sources of possible ignition. [29 CFR 1915.35(b)(4)]
• Periodic tests must be conducted by the Shipyard Competent Person to ensure the exhausted vapors are not accumulating in other areas within or around the vessel or dry dock. [29 CFR 1915.35(b)(4)]
• Explosion-proof motors, fan blades, and portable air ducts must be non-ferrous. [29 CFR 1915.35(b)(5)]
• All footwear worn during painting operations must be non-sparking. [29 CFR 1915.35(b)(9)]
• PPE must not produce static electrical sparks. [29 CFR 1915.35(b)(9)]

• All metallic parts of paint spraying equipment must be grounded and bonded to the vessel. [29 CFR 1915.35(b)(12)]

 

Potential Hazard

Toxic vapors and mists from paints and paint solvents may present significant health hazards due to inhalation during painting operations. These vapors may accumulate in low-lying areas as well as enclosed spaces where they displace the air and lower the oxygen content.

Requirements and Example Solutions

• A hazard assessment must be conducted to determine the proper selection of respirators. [29 CFR 1915.152(b)]
  • The components of epoxy, isocyanate, anti-fouling, and coal tar pitch paints may be particularly dangerous to workers' health and call for special precautions.
  • Many of these paints cause respiratory and skin sensitization and allergic reactions, which may be life threatening.
  • Respirators must be used in accordance with the PPE section 29 CFR 1915.154.

 

When paints are mixed with toxic vehicles or when solvents are sprayed the following respiratory protection procedures are required:

• Continual Air Monitoring
  • The Shipyard Competent Person (SCP), Certified Marine Chemist (CMC), or Certified Industrial Hygienist (CIH) may require continual monitoring to determine that vapor/mist air concentrations are within the PELs and below IDLH levels while workers are in the area.
  • If the concentrations are above appropriate levels, additional administrative controls (e.g., exposure time limits), engineering controls (e.g., ventilation), or PPE (e.g., respirators) are required.
• Use of Airline Respirators
  • Airline respirators are required in confined spaces to protect employees who are continuously exposed to toxic materials during coating operations. [29 CFR 1915.35(a)(1)(i)]
  • Airline respirators are required in enclosed spaces to protect workers when mechanical ventilation is not provided, [29 CFR 1915.35(a)(1)(ii)] or when the flash point of the paint or solvent is less than 80º F. [29 CFR 1915.35(b)(13)]
• Use of Air Purifying Respirators (Filter Respirators)
  • In tanks and compartments where mechanical ventilation is provided, employees continuously exposed must be protected by filter respirators, at a minimum; in accordance with Subpart I (29 CFR 1915.154). [29 CFR 1915.35(a)(1)(ii)]
  • In large and well-ventilated areas, employees exposed to spray painting must be protected by filter respirators in accordance with Subpart I (29 CFR 1915.154). [29 CFR 1915.35(a)(1)(iii)]
  • All employees doing exterior spray painting with material containing solvents with flash points below 80º F must be protected by suitable filter cartridge-type respirators, at a minimum; in accordance with Subpart I (29 CFR 1915.154). [29 CFR 1915.35(b)(14)]
  • Employees entering compartments where spray painting is being done with paints containing solvents with a flash point below 80º F, for a limited time, must be protected with filter cartridge type respirators, at a minimum; in accordance with Subpart I (29 CFR 1915.154). [29 CFR 1915.35(b)(13)]

When coatings are applied by non-spray methods, the following respiratory protection procedures are required:

• Air Purifying Respirators (Filter Respirators).
• When brush application of paints containing toxic solvents is done in confined spaces or in other areas where lack of ventilation creates a hazard, filter respirators at a minimum in accordance with Subpart I (29 CFR 1915.154). [29 CFR 1915.35(a)(2)]
