Gas Masks & Respirators

This section provides information on what respirators are, how they work, and what is needed for a respirator to provide protection. For the most part these devices provide a false sense of security, which makes them dangerous if you do not fully understand their specific usage and limitations. You should become familiar with the information the Biological and Chemical sections of this guide in order to make an informed decision.

In the event of biological attack — Because of the incubation period, which can be weeks, it is probably too late. A standard, N95 rated, surgical mask offers protection only against airborne particles.

In the event of a chemical attack — You may need protective clothing as well as a gas mask — many of these chemicals are absorbed through the skin [dermal contact].

It is more important to have an emergency plan in-place and understanding the risks. A gas mask or respirator is only one small part of that plan. In many situations it is simply best to stay where you are and avoid any uncertainty outside — A process known as “sheltering-in-place,” as a means of survival.

Use all available information to assess the situation. If you see large amounts of debris in the air, or if local authorities say the air is badly contaminated, you want a respirator to filter the air if you have to be outside. A respirator will not protect you against chemical agents.

Respiratory protection is effective only if:

The correct respirator is used
It’s available when you need it
You know when and how to put it on and take it off
You have stored it and kept it in working order in accordance with the manufacturer’s instructions
