Victims caught in a fire have inhaled toxic smoke from furnishings and plastics that have released cyanide in the burning process. Deposit in container with plastic liner. The longer a contaminant is in contact with an object, the greater the probability and extent of permeation. For labs that process routine patient specimens, that microbial presence may exist in the form of bloodborne pathogens, bacteria, fungi, and even prions. This course is specifically designed to provide selected personnel with training in CBRN Decontamination Operations techniques and . The impact of the decontamination process and compounds on worker safety and health. initial medical treatment after an incident but not involved with decontamination? Remove and open canteen.

Avoid touching face with fingers. Emergency decontamination has become a major response objective of first responders to terrorist incidents. Extend both arms horizontally sideways with clenched fists facing up. Hazardous Response Support Division, Washington. Similarly, any injuries to the skin surface, such as cuts and scratches, may enhance the potential for chemicals or infectious agents that directly contact the worker's skin to penetrate into the body. 14.
