IAFF Training for Hazardous Materials: Technician© Student Text core temperature. If they are needed for rescue, they should be rested, unstressed and with full air capacity. A good donning team can have them ready for entry in less than one minute. However, there may be situations when backup personnel are on air and partway into zone to reduce travel time to the entry team. Generic Doffing Procedures Many jurisdictions use the donning group/sector to perform the doffing operations. Since members being doffed of chemical protective clothing have usually been contaminated and decontaminated, doffing group/sector personnel may need CPC for the operation. This level of protection should be determined by the Safety Officer and/or Doffing Group/Sector Supervisor. Usually, only chemical protective gloves are required, but some contaminants may require eye and/or body/respiratory protection. If you are assisting in doffing operations, be aware that the entry team members are likely tired, very warm, and anxious to remove their chemical protective clothing. Their vision may be obscured by fogged facepieces. Watch these individuals for signs of heat stress. Entry personnel should be doffed according to procedure or manufacturers’ instructions. It is important to expose them to ambient air so they will cool quickly. As soon as possible, entry team members should be seated and remain seated. • Assisting personnel should touch only the outside of the chemical protective garments. • Entry team personnel should touch only the inside of the garments. • All efforts should be made to eliminate crosscontamination from outside to inside of the garment. • Once removed, garments should be zipped (when appropriate) or stored so that inside and outside surfaces do not touch, then placed in a containment bag for further evaluation and decontamination. 7-58 Module 7: Personal Protective Equipment
Student Text IAFF Training for Hazardous Materials: Technician© The last item removed should be the SCBA or other respiratory protection. It should be removed by the wearer. SCBA should be placed in a clean area for any special cleaning and then the normal post-use checks and maintenance. After doffing, entry personnel should be hydrated, medically evaluated, and debriefed regarding their mission. The donning and doffing of chemical protective clothing is a cooperative effort of the entire response team. It requires pre-planning, adherence to procedures, and continued practice. Activity Other Items Used With Protective Clothing Some departments use other items or materials in conjunction with chemical protective clothing—often inappropriately. Perhaps the most popular of these items is duct tape. This tape has been used to seal seams, cover zippers, tape extra material for better fit and seal facepieces to garment hoods. There has been little data regarding the protective value of duct tape against chemical attack. The most recent data shows that duct tape has no protective value whatever, and in some circumstances can add risk by reacting with chemicals or damaging suit materials. In general, avoid using duct tape on chemical protective clothing material. There may be occasions when duct tape may be useful, such as taping a glove to itself to tighten it around a wrist. However, in these cases, the items are usually disposable and the tape is only applied to itself. Remember that compliant garments meet penetration and/ or gastight integrity standards without the use of additional items. Using duct tape on these garments is unnecessary and may actually damage expensive re-usable garments. Furthermore, it may void any warranties from the manufacturer.
