and properly decontaminate their victims, fellow emergency response personnel, equipment, and the environment by the systematic isolation, neutralization, or removal of contamination.

Effective decontamination guidance can be & found by consulting regulations, © Jones & Bartlett Learning, LLC © Jones Bartlett Learning, LLC consensus standards, and best practices. Some examples include 29 CFR NOT FOR SALE OR DISTRIBUTION NOT FOR SALE OR DISTRIBUTION 1910.120, National Fire Protection Association (NFPA) Standard 472, and the OSHA Best Practices for Hospital-Based First Receivers of Victims from Mass Casualty Incidents Involving the Release of Hazardous Substances.

For generations prefire planning has helped fire fighters to mitigate potential problem areas in their response zones and to make faster, safer, and more efficient responses to a citizen call for help.

My personal experience in © Jones & Bartlett Learning, LLC © Jones & Bartlett Learning, LLC Hazardous Materials planning and response, as well as in Emergency Management for the healthcare industry, NOT FOR SALE OR DISTRIBUTION NOT FOR SALE OR DISTRIBUTIONhas shown that preplanning is equally important to the Hazardous Materials Responder. By taking the time to preplan their community, a response team can perform a hazard vulnerability analysis, determining where their focus on training and response protocols need to lie. In addition, preplanning will help to ensure that appropriate types and quantities of decontamination agents are readily available and their application strategies are understood through appropriate training.

©January Jones & Bartlett Jones &ofBartlett Learning, LLC In the early morning hours of 6, 2005, a NorfolkLearning, Southern trainLLC derailed in the small rural South© Carolina town Graniteville, resulting in the release of over 60 tons of liquefied gas into the night air, killing nine people and displacing over SALE 5000 from NOT FOR OR DISTRIBUTION NOT FOR SALEchlorine OR DISTRIBUTION their homes. In all, 554 people were treated at area hospitals, 75 were admitted, and nine would eventually die from the poison. The expected response of local, state and federal agencies ensued and a Unified Command was established to manage the scene.

While many lessons were learned and opportunities for improvement presented themselves in the aftermath (as is true for most disasters), one particularly effective practice involved the use and coordination of a variety of decon resources from area agencies, © Jones & Bartlett LLC © alike.

Decon does not need to be the most difficult of the Eight Steps, but it also should not be disregarded as simple or something that doesn’t require preplanning. Taking the time to research the resources available in your district to assist in a complex event, learning of the specific hazards that may be present during an emergency, and ensuring that the appropriate decon agents are on hand—is truly time well spent.
