Cleaning and Other Cold Work >> Cleaning Operations
Cleaning and cold work in shipbreaking may include tank cleaning, mucking, or wiping down salvaged equipment.
After the spaces are evaluated by the Shipyard Competent Person (SCP), Certified Marine Chemist (CMC), or Certified Industrial Hygienist (CIH), the personnel, equipment, and materials required for the cleaning and cold work must be determined. In addition, a hazard assessment must be conducted for selecting appropriate personal protective equipment (PPE). See PPE for Cleaning Operations. [29 CFR 1915.152(b)]
Cleaning agents may include:
- Toxic cleaning solvents (for example, mineral spirits, diesel fuel, and degreasers)
- Chemical removers (for example, paint strippers, and methylene chloride)
- Flammable and combustible liquids
Hazards associated with cleaning and cold work include:
- Hazardous Atmospheres (See Confined Space Chapter)
- Fire and explosion hazards
- Respiratory hazards (See Shipbreaking Common Hazards)
- Toxic cleaning solvents
- Excessive noise
- Biological hazards
- Limited access hazards (See Shipbreaking Common Hazards)
- Slips and trips
- Fall hazards (See Shipbreaking Common Hazards)
- Work Environment temperature related hazards (See Shipbreaking Common Hazards)
