HazMat Continued: Shelter-In-Place

For the past several weeks we have been discussing how to become better equipped to deal with a potential HazMat incident. Last week Rod Cook, E.D. of our local Red Cross, gave us some of his views on dealing with a chemical cloud incident, which is his greatest concern. He covered the two methods of sheltering: off site and in-place. For this training tip we will briefly consider the latter, which may be necessary because of time considerations or insufficient external shelter facilities available to accomplish the former. Shelter-in-place does not mean completely sealing off your home or any other building. In the case of a chemical incident it also does not mean seeking shelter in a basement or lowest possible level, as we are instructed to in a tornado warning. Chemical gases are usually heavier-than-air and fall to the ground over time and can settle in basements or low-lying structures. It means selecting a small interior room, as high as possible, with no or few windows, sealing it off and taking refuge there. Duct tape, plastic trash bags, sheet plastic, bed sheets, towels, etc. are valuable resources at such a time. Instructions to shelter-in-place are usually provided for durations of a few hours, not days or weeks. There is little danger the room you are sheltering in will run out of oxygen, causing you to suffocate.

There are four venues where sheltering-in-place may become necessary. They are at home, at work, at school, or in a vehicle. The first three are similar but obviously have their differences and specific needs, the details of which will not be covered here. Those in a vehicle at the time of an incident have a quick decision to make, depending on the relative location of the incident, wind direction, and their distance from home or a shelter. If the latter are reasonably close, go there. Otherwise shelter in the vehicle using techniques similar to anywhere else. Keep a roll of duct tape and some plastic sheeting or a trash bag or two in your vehicle.

The purpose of this training tip was to get each of us better informed on this topic so we can better protect or our own safety, that of others, and be better communicators in the event of an incident. As mentioned in last week’s training tip, you can find a detailed Red Cross fact sheet on this topic at the following web site:
