Recommendations |
| Objective: To ensure safe workplace practices for each activity during the treatment process |
| For all activities |
- PPE(personal protective equipment): material impermeable to organic solvents, with a resistance rating for PCP:
- excellent - viton, neoprene, butyl rubber
- good - nitrile, polyvinyl chloride (PVC)
- fair - polyvinyl alcohol, polyethylene
- PPE: Respirator cartridges must be National Institute for Occupational Safety and Health (NIOSH)-rated for protection from organic vapours and acid gases, in combination with a dust mist and fume filter
|
| Unloading PCPsolids |
- PPE: Approved respirators should be readily available. Wear full face protection respirators whenever exposureFootnotea to dust can occur.
- Do not wear contact lenses.
- Provide adequate equipment for safe, controlled handling of blocks as appropriate for the specific facility
- Do not drop PCPblocks.
- Immediately vacuum PCPchips or spilled solids (vacuums should have effectively filtered exhausts).
|
| Unloading PCPsolution |
- Wear an approved full facepiece respirator whenever dust conditions occur. Respirator cartridges must be NIOSH-rated for protection from pesticides and organic vapours and dusts.
|
| Preparing PCP work solutions |
- PPE: Wear an approved full facepiece respirator whenever dust conditions occur.
- Thoroughly vacuum PCPdust and solids from the work area following solution preparation.
- Dispose of empty PCPwraps and PCP-contaminated debris according to Table 23.
|
| Sampling procedures |
- Wear eye protection and gauntlets resistance rating for PCP when sampling PCP solutions, e.g., from a pipe tap.
- Should wear respirators and must be in accordance with NIOSHguidelines (pesticide, polynuclear aromatic hydrocarbons and organic vapours cartridges, and dust) when sampling PCP solutions or treated wood (if at temperatures above ambient).
- Other non-routine sampling efforts such as through cover ports may necessitate more stringent precautions.
|
| Cleaning cylinders or storage tanks |
- PPE: Wear NIOSH-approved breathing apparatus, organic-solvent-impermeable gauntlets, outer clothing and boots during all vessel entries.
|
| Handling treated lumber |
- PPE: Change coveralls daily. Wash separately from other laundry.
|
| Handling and maintaining contaminated equipment |
- Thoroughly steam-clean or flush contaminated equipment with hydrocarbon solvent (e.g. Varsol or equivalent) prior to handling. Contain all solvent washings.
- PPE: Change coveralls daily.
