IAFF Training for Hazardous Materials: Technician© Student Text permanently) inside the facepiece and a member can have the appropriate lenses made for it. Wearing contact lenses, which in some OSHA interpretations had been considered a “de minimus” violation (no fine imposed), is now gaining favor. Soft or gas permeable lenses appear to now be allowed by OSHA (Feb. ‘98 interpretation), although their use will be documented. OSHA has also requested users’ experiences with contacts, both good and bad. In any case, devices worn to correct vision cannot interfere with the seal of the facepiece. Entry and backup personnel should be medically evaluated for inclusion criteria. Hydration should begin and continue through the donning process. A Donning/Doffing Group or Sector should be established in the Incident Management System, with sufficient manpower allocated. Manpower for this sector will require a supervisor and personnel to don four team members in chemical protective clothing. Whenever possible, two persons should be assigned to dress one member in chemical protective clothing. At a minimum there should be a one to one ratio. Donning and doffing areas should be pre-selected. These areas should be near each other, if not adjacent. The area should be: • Located as close as possible to entry point, but still isolated from distraction • Sheltered from the elements (wind, rain, sun). Existing, non-involved structures may provide suitable shelter and isolation. Commercial portable structures are also available, as are consumer type shelters (tents, canopies). • Large enough to accommodate personnel donning and those assisting (8-12 personnel) • Clearly delineated. This may be accomplished by the use of road cones and banner tape. Another popular method is to use an appropriately sized synthetic tarp. This clearly marks the area and provides a clean work platform. 7-56 Module 7: Personal Protective Equipment
Student Text IAFF Training for Hazardous Materials: Technician© CPC items should be deployed in an organized manner. Check all items for operation. Move zippers, visually inspect clothing, test SCBA or SAR, and deploy and check communications devices. Entry and backup personnel should be allowed to hydrate through the donning process and have stable seating without backs (which would interfere with SCBA). Some jurisdictions modify chairs; others use short stepladders for each person donning CPC. Entry and backup personnel should receive a briefing regarding their mission, work activities, possible hazards and emergency signals. Briefing should take place before team members suit up; it should not take place during the donning process. Briefing personnel during the donning process is distracting; briefing after the donning process will just keep personnel in CPC longer. Entry and backup personnel should repeat their instructions to the briefing personnel to ensure understanding. Entry and backup personnel should dress at the same rate. That is, they should all be brought to the same level of dress at the same time (e.g., legs in suits, arms in suits, etc. at the same time). This is best accomplished with adequate manpower and supervision. The supervisor of the donning group/sector should closely watch the level of dress on each member and re-assign manpower as needed to ensure that personnel are fully dressed at the same time. If you are donning CPC, allow yourself to be dressed and expend a minimum amount of energy in the process. Relax as much as you can to minimize your stress level. Entry and backup personnel should be brought to a “stand-by” level. Personnel should be dressed as completely as possible without going on air. All overgarments should be in place. When it is time to enter the hazard area, the donning supervisor should give the order. The entry team should be put on air, the donning process completed, and the entry team led to the access point. Before entry, the entry team should be checked by another experienced person, such as a Safety Officer. The backup team should remain at the stand-by level until needed. Backup is usually left off air. If backup is sealed and on air, their stress level will increase as will Module 7: Personal Protective Equipment 7-57
