"The use of gas masks and hoods by the public during a chemical threat is not recommended due to legitimate safety concerns," according to the site. Use of these bulky, heavy masks and tanks, however, requires more training than most civilians have had.īecause of their limitations, - the disaster-preparedness website developed by the federal government - doesn't recommend the use of any gas masks. That's why many professionals, including hazmat teams and emergency first-responders, wear full-face masks that are connected to an air supply, such as a small air canister or a scuba-style air tank. There are other limits to the effectiveness of these masks: They don't always provide eye protection, and any mask is only as good as the seal around the wearer's face - a leak or a weak seal would render them useless. Most activated charcoal masks have disposable filters that are easily replaced. As long as there's space on the charcoal filter's fibers for incoming toxins, the wearer is safe.īut after a period of time - depending on the density of toxic chemicals in the air, the wearer's rate of breathing and other factors - an activated charcoal filter will stop working and will need to be replaced.
Those threats require a mask with activated carbon, also known as activated charcoal.Ĭharcoal bonds with the active ingredients in nerve gas and other chemical threats, effectively filtering those toxic compounds out of the air inhaled by the mask's wearer. Paper-filter masks, however, are useless against most chemicals, whether paint fumes, sarin gas or airborne organophosphates. (The average human hair is 70 micrometers in diameter.) These masks are rated by the amount of particles they can filter: A mask rated 95 will stop 95 percent of airborne particles that are 0.3 microns in size and larger, while a mask rated 100 will filter out 99.97 percent of particles 0.3 microns and larger, making it comparable to a HEPA (high-efficiency particulate air) filter. We do not carry the smallest todler or infant sizes, this one is as small as we have.Inexpensive face masks, like the disposable paper-filter masks available in hardware stores, are effective only against airborne particles. If your child head size is smaller than most others of the same age group we may not be able to help you. Child 3 large would tend to fit 3-5 year old heads. This one is a child size ‘3 Large’ but there was 5 smaller sizes available and one larger.
KIDS GAS MASK HOW TO
See attached photo on how to determine your child’s proper size.
There were 5 different adult sizes and 7 child sizes. The filters with our Russian masks are from the mid to late 70’s. Even if there is any asbestos in them, you should be safe if the filter is not damaged. If you are worried about this you might just want to get filters from other counties as a replacement. Best we are able to determine is they did before 1972, but was eliminated or mostly eliminated after that time. There is a great debate on the internet whether or not the supplied filters contain asbestos. The hose is included and attached to the child sized masks and the filter must be held in the hand or strapped to the body due to weight and space restrictions on the mask itself. The child size filters are the exact ones the adult sizs use. However you will find that they are close enough that you can effectively use the standard 40mm thread cartridges with this mask. The Soviet 40mm filter cartridge thread design that comes with the mask is slightly different than most other 40mm NATO cartridges on this website. It is the smaller cousin to the GP-5 adult masks with straps rather than the ‘shower cap’ design and is quite effective when the correct size is obtained. The classic Soviet era PDF-D gas mask was intended for Cold War child Civilian use.
