Information about masks usage:

- mask are not toy: They must be only used if your life is threatened, and just for the required time to leave the toxic area.
- You must not use it if there is no danger. You must not voluntarily go to a toxic area because you think you are protected by a mask. Like any other protection a mask cannot protect you from 100% of the danger.
- You must put the mask very meticulously, even if there is an alert. Your hair must not hinder contact between the mask and the skin. If you wear a beard it can prevent airtightness.
- Read attentively the mask and filter instructions for use.
- Masks are for ADULT only. Do not give them to children, do not let children find it, do not let children play with it: they must suffocate if they do not use it properly.
- When in use, filters cartridges must be changed every few hours, do not reuse old filters: trash them.
- A gas mask is not a magic protection to all kind of threat. It is a way to greatly improve your protection against toxic airborne agent but it is not infallible.
- To wear a mask is the first step for a good protection. Others steps may be suitable like wearing an airtight suit, or better a full closed air system with oxygen bottles.
