The addition of voice amplifiers and radio cables might also be mandatory depending on your task and purpose. A CamelBak adapter is readily available for most masks with drinking tubes. Remember that you may not be able to take off the mask for several hours, and without a hydration port, you won’t be able to drink anything during that time. A hydration tube port is always a welcome feature - in some hotter climates and more strenuous conditions it should be considered mandatory. It should be easy to don without a complex webbing system, and lastly it should be comfortable to wear for prolonged periods. To learn more about the accreditation system you can visit The upper portion of your mask should provide clarity of vision and keep peripheral vision obstructions to a minimum. Masks are certified, but only filters are rated. Filter adapters are available, but introduce an additional point of potential failure in a very important system.

The MSA Advantage doesn’t have this feature, so its value is diminished as a result. A NIOSH-rated (National Institute for Occupational Safety and Health) CBRN filter will handle damn near everything. This will allow you to choose from a variety of NATO filters. Ideally, the mask you choose should accept filters with a 40mm NATO thread. BR and silicone are most common since they provide a great sealing surface as well as resistance to a large variety of agents. Butyl rubber (BR) and silicone are the most common, with butyl rubber being more resistant to UV and different types of chemicals. In conjunction with the type of filter chosen, the mask’s materials are also important. Selecting a full-face mask isn’t enough on its own - you’ll also need to consider its level of protection. The general health checkup is still important for training in a mask though, so please don’t neglect it. Of course, if you’re faced with a situation where a mask is truly needed, you’ll need to weigh the potential health risk of wearing it versus that of exposure. Most occupational health clinics can perform this type of checkup since they routinely do it for cops and occupations that require respirators. It goes without saying that you should be checked by a doctor to determine whether you’re healthy enough to wear a mask, how long you should wear it, and whether or not prolonged use might have adverse health effects. Add in any physical activity, and it only gets worse. Drawing breath will be harder in an APR - you’re pulling air through a fairly dense filter, so normal breathing will be affected. So, if the face-hugger creatures from the Alien franchise really freak you out, air-purifying respirators (APRs) will take some getting used to. Hyperventilating and feelings of claustrophobia are fairly common. Plenty of people lose their minds as soon as the “octopus” attaches to their face. All of those areas need to be covered to be properly protected, hence the need for full-face protection. These types of agents not only affect your breathing, but they’re particularly good at disrupting your moist bits, like eyes, mouth, and nose. Considering the nature of these hazards, only full-face respirators are considered. In this article, we’ll discuss two types of threats: CBRN (chemical, biological, radiological, and nuclear) and RCAs.

That type of threat requires full body protection and coverage - but level A to D chem suits are a topic for another day. If it’s something more nefarious, like VX nerve agent, then a mask is only the first step since the agent can also be absorbed through exposed skin. The penalty for exposure to RCAs is discomfort for a brief period of time. And depending on how uncomfortable you want to be, so will a wet sponge. If the anticipated threat is simply riot control agents (RCA), then any of the masks listed here will be fine. The first question you should consider is whether you even need a gas mask.

Today, the M17 is nothing more than a conversation piece since the filters contain chromium, which we now know to be a carcinogen. Lots of people are familiar with the M17 military gas mask, but like everything in life, filters and composition have improved. As threats changed, so did the masks and the technology behind them. Early “masks” were just wet sponges covering the user’s mouth and nose. The history of gas masks is long and varied, in hopes of matching the threat from various different types of agents.
