Everything You Need to Know About Gas Masks

Gas Masks

In the past, only soldiers really needed to worry about needing a gas mask. However, with today’s threats, it’s becoming more and more likely that civilians will be exposed to all kinds of hazardous substances.

Riot control agents from police, fallout from nuclear attack, biological warfare agents, toxic smoke from terrorist attacks and more are all possible reasons that your everyday person may need to have a gas mask.

The real question is do you need to buy a ? Keep reading to find out.

Do You Need A Gas Mask

Do you need a gas mask?

Many people often wonder if they even need a gas mask. It’s a good question and one that isn’t necessarily cut and dry.

In my opinion, you need to get some kind of gas mask if you’re a serious prepper, but only after you have all of your other essentials covered. If you have all the water and food you think you’ll need, a defensive firearm and ammo, and have added even more water and food then you’re probably at the point when you should buy a gas mask.

Of course, if you’re not on a budget and just feel like picking up a gas mask now, by all means, go for it. Just know that buying gas mask doesn’t need to be a priority for most people. You may want to prioritize the purchase of a gas mask if you live in a major city that is likely to face police using riot control agents.

What makes a good gas mask?

Quality gas masks are relatively inexpensive these days. Even gas masks that are specifically produced for the public are of high quality and very accessible to almost everyone.

Military surplus gas masks can be hit and miss. Don’t just assume that surplus gas masks are made well or of good quality because they are used by other militaries.

How to Inspect a Gas Mask

How to Inspect a Gas Mask

Any gas mask should be inspected as soon as you receive it and annually when it’s in storage. This is especially true for military surplus masks.

To inspect your gas mask start by looking at the rubber itself. If there are any cracks or dry rot, then you need to get a new gas mask.

Next, inspect ant areas where the rubber meets other types of material. Aeras where rubber and metal or rubber and plastic meet are common points of failure. Gently pull at these areas to make sure they are solidly connected and not going to come apart.

Inspect whatever type of facepiece or eye covers your mask has. Check the seams to make sure it is securely attached and look through them to ensure that they aren’t cloudy and you can see clearly through them. If there are cracks or gaps in the seam, replace the mask. If the facepiece is cloudy, then it’s up to you to decide if it obstructs your vision enough to replace it.

Check your head harness. It should allow you to easily and securely attach the gas mask to your face. If it doesn’t, replace the head harness or replace the mask.

Check every valve the mask has as well as things like drinking straws and voicemitters. Most gas masks have several one-way valves. These can dry rot, deteriorate, and even be installed the wrong way.

Take special attention when you’re inspecting the valves. Any valves that are stuck or sticky should be replaced. If they stick while the mask is on your face it can make it so you cannot breathe.

After you’re sure that everything is working properly and in good shape, put the mask on and cover the inlet on the filter with your hand. Try to inhale. You should not have any air leaking into the mask from the seal around your face or any seam on the mask.

If you hear air leaking into the mask then the seal is the most likely problem. Make sure you don’t have any hair between your face or forehead and the mask and try to tighten the head harness. If this doesn’t work then your mask is either compromised or doesn’t fit your face properly.

What do gas masks protect you from

What do gas masks protect you from?

A gas mask protects you from particulates and some chemical vapors in the air. This means very small pieces of solid material floating in the air are filtered out and chemicals are absorbed by an activated charcoal layer. It does not provide oxygen and will not protect you from environments that do not contain oxygen.

Most preppers will want a gas mask to protect from either riot control agents used by the police and military or to protect from alpha particles following a nuclear attack or dirty bomb. These are the most likely uses for a gas mask in my mind, but that doesn’t mean that there aren’t other logical reasons to own a gas mask.

Chemical weapons are one of the main reasons that gas masks exist at all. It may not be a likely scenario, but gas masks can protect you in the event of a chemical attack.

They can also protect you in the event of a biological attack or even in the event of some types of pandemics!

You really need to understand that a gas mask doesn’t make you impervious to chemical, nuclear or biological attacks, but it does add an extra layer of protection that you otherwise wouldn’t have.

What don’t gas masks protect you from?

As we said before, a gas mask will not allow you to breathe in an atmosphere that doesn’t contain any oxygen. However, that not the only thing it won’t protect you from.

This should go without saying, but a gas mask only protects the area that it’s covering and your respiratory system. Your body is still exposed to anything it comes in contact with.

This means that if you come in contact with a chemical agent that can absorb through your skin, then you will still suffer the effects of that chemical agent. This is also true if you get contaminated and then remove your gas mask. Whatever is on your body may still be able to injure or kill you. If you get contaminated with a toxic substance, you need to decontaminate yourself before you remove your mask and any protective clothing!

The same is true for nuclear material. Just because your gas mask says it protects from nuclear contamination doesn’t mean that it protects from all types of nuclear particles. In fact, it only protects you from alpha particles. All other forms of radiation will still be bombarding your body!

How Long Can You Wear A Gas Mask For

How long can you wear a gas mask for?

The length of time that you can spend in a gas mask depends on a number of things. How active are you being while in the mask? What is the weather like? Do you have a drinking tube and canteen?

The main thing that prevents you from wearing a gas mask for extended periods of time is the ability to drink water. If you have a gas mask with a drinking tube and a canteen that can attach to it then you’ve defeated this. If not, you’re going to be severely limited in the amount of time you spend in a mask.

Activity level and weather also play a major role in how long you can spend in a mask. If you’re running or fighting, then you’re going to need much more water than someone who is relaxing in a chair in the air conditioning. You can be as active as you want in a mask as long as you’re physically able to keep going and can keep getting clean water.

Some people bring being able to eat, pain and discomfort into the equation. Wearing a gas mask is extremely uncomfortable, but comfort doesn’t play a role when you’re trying to survive. You can also go for weeks with no food. Again, comfort doesn’t play a part when you’re trying to survive.

What type of gas mask filter do you need?

A standard NATO 40mm canister is what we recommend. These are common among police and military-issued gas masks so you shouldn’t have a problem finding them for sale.

It’s fine to decide to go with a gas mask that uses a different type of canister. Just know that you may have a more difficult time finding replacements.

How often do I need to change my gas mask filter?

People don’t often realize that gas mask filters expire and need to be replaced when they’re exposed to chemicals.

Sealed and packaged filters typically claim to last for around 5 years. This is normally a very conservative timeframe. We suggest using the manufacturer’s suggested shelf life whenever possible. In a real emergency, you may be able to get away with using a filter after its shelf life has expired as long as you understand that you may get less protection than expected.

You should also change your filter after it’s been exposed to chemical agents. This should be accomplished between 8 and 24 hours after exposure. Be aware that certain chemical agents can cause a filter to stop being effective in as little as 30 minutes.

When a filter is exposed to particulate matter it doesn’t need to be changed as often. As long as the filter still allows you to breathe through it without much restriction you should be good to use the filter up to 30 days.

Any time a filter is damaged you should replace it. Dents and dings on the outside could mean that the filter inside is compromised.
