What You Should Know in Deciding Whether to Buy Escape Hoods, Gas Masks, or Other Respirators for Preparedness at Home and Work

Some employers and consumers are considering purchasing escape hoods or other respirators to protect themselves against potential terrorist threats, including biological and chemic substances. This guidance will provide information on what respirators are, how they work, and what is needed for a respirator to provide protection.

Is buying an escape hood or other blazon of respirator the all-time way to protect myself, my family, and/or my employees?

If available and used correctly, a respirator tin selectively reduce the exposure you might otherwise receive. Respirators accept been used for many years in the workplace, where employers take programs to make sure the proper masks are selected and that the respirator fits. When consumers apply respirators, they don't take such support, so this fact sheet includes lots of background information to help consumers empathize the limitations and cautions that demand to be considered. The goal is to avoid unintended problems that might occur through lack of understanding or a simulated sense of security.

Every bit a first footstep, plan how to respond if an emergency happens. A respirator is but one small part of that plan. There may exist situations in which it'southward simply best to stay where you are and avoid any dubiousness outside, a procedure known as "shelter-in-place," as a means of survival. Utilise available information to assess the situation. If you see big amounts of debris in the air, or if local authorities say the air is badly contaminated, you may want to have this kind of action. The US Department of Homeland Security offers data on shelter-in-identify and other emergency planning recommendationsexternal icon on its Internet site, and through a cost-costless number, 1-800-Be-READY.

Respiratory protection is effective only if:

• the correct respirator is used,
• information technology's available when you lot need it,
• you know when and how to put it on and accept it off, and
• you lot take stored it and kept information technology in working order in accordance with the manufacturer's instructions

Each blazon of respirator can come in several varieties, each with its own set of cautions, limitations, and restrictions of use. Some respirators crave testing to ensure a tight fit to the face up, and should not be used with facial hair. Others employ a olfactory organ clip and mouthpiece, which is clenched between your teeth, similar to a snorkel. Some respirators preclude the user from talking while others take speaking capabilities. Every respirator contaminated with chancy chemicals should be decontaminated and disposed of properly.

All respirators require training to be properly used. Sometimes you lot can practise using your own respirator. Some escape respirators come in a package that must remain sealed until apply, so you need to be trained using a special "exercise" version. Training is extremely important in regard to the storage, maintenance, use, and discarding of the respirator. This information is provided past the supplier of the respirator (i.e. seller, benefactor, or manufacturer).

If you exercise not use a respirator correctly, it is very likely that it will not protect y'all-and may even hurt you lot. The following information will help you understand what a respirator is, and how information technology should be used.

What is a respirator?

A respirator is a device to protect you from inhaling dangerous substances, such as chemicals and infectious particles. There are several unlike types of respirators, as described beneath.

EscapeRespirators

Escape respirators are designed to be used only in an emergency, and only to escape from a unsafe area to a safe area. There are several escape respirators on the market place. Many of them use a hood with a neck seal instead of a facepiece. They are typically designed for one-time use for a brusque period, typically 15 minutes to one hour. They may be available in a variety of sizes and will fit most adults. Individuals with small or very big cervix sizes may not exist able to utilise some escape hood designs-check the supplier product information before purchasing.

Particulate Respirators

Particulate respirators are the simplest, to the lowest degree expensive, and least protective of the respirator types available. These respirators but protect against particles. They exercise not protect against chemicals, gases, or vapors, and are intended just for low run a risk levels. The ordinarily known "N-95" filtering facepiece respirator is ane type of particulate respirator, often used in hospital to protect against infectious agents. Particulate respirators are "air-purifying respirators" considering they clean particles out of the air as you breathe. Fifty-fifty if you can't see the particles, there may be too many in the air for this respirator to provide adequate protection.

Chemical Cartridge/Gas Mask Respirator

Gas masks are also known as "air-purifying respirators" considering they filter or clean chemical gases and perhaps particles out of the air as you lot breathe. This respirator includes a facepiece or mask, and a filter/cartridge (if the filter is in a metal crush it is called a "canister"). Straps secure the facepiece to the head. The cartridge may have a filter to remove particles (such as a biological weapon), charcoal (to remove sure chemicals), both, or other parts. When the user inhales, air is pulled through the filter.

Gas Masks are effective but if used with the correct cartridge or filter (these terms are often used interchangeably) for a particular biological or chemical substance. Selecting the proper filter can exist a complicated process. There are cartridges available that protect confronting more than one run a risk, but there is no "all-in-one" filter that protects confronting all substances. You need to know what hazards you will face up in order to exist certain you are choosing the correct filters.

 Powered Air-Purifying Respirator (PAPR)

Powered air-purifying respirators use a fan to blow air through the filter to the user. They are easier to breathe through and they demand a fully charged battery to piece of work properly. They apply the same filters every bit gas masks, so you lot need to know what the gamble is, and how much of it is in the air.

Cocky-Contained Breathing Apparatus (SCBA)

Self-Contained Breathing Apparatus (SCBA) is the respirator commonly used past firefighters. These employ their own air tank to supply clean air, and so y'all don't need to worry about filters. They also protect against college concentrations of dangerous chemicals. However, they are very heavy (thirty pounds or more), and require very special training to use and to maintain them. Likewise, the air tanks typically last an hour or less depending upon their rating and how hard you are breathing.

The following questions and answers provide additional data for use in selecting and using gas mask and escape respirators.

At the end of this Fact Sheet, yous volition discover a list of questions y'all should ask before purchasing a Gas Mask or Escape Respirator.

Can I purchase any Gas Mask or Escape Respirator and await it to protect me from anything that might happen?

These respirators must exist selected for protection confronting a specific run a risk.
The cautions, limitations and restriction of utilise provided with the respirator must be strictly followed. If your mask does not make a tight seal all the way effectually your face when you inhale, you lot may exhale contaminated air that leaks effectually the edges of the face seal. Anything that prevents the face mask from fitting tightly against your confront, such as a beard or long sideburns, may cause leakage. Some respirators come in different styles and sizes, and fit different people differently considering people's faces have different shapes. You also demand grooming to know how to correctly put the mask on and wear information technology correctly. This information should be provided by the supplier of the respirator.

If I have the right cartridges/filters for a sure hazard, and my mask fits, will they ever protect me against that hazard?

Gas Masks and Escape Respirators reduce exposure to the gamble, but if the exposure is such that it goes beyond what the filter is capable of handling (either because the amount of toxic gas or particles is more than what the filter is designed to handle, or because the exposure lasts longer than what the filter is designed to handle), the filter may not be effective in providing required protection. Also, there may be a small amount of leakage even if the fit of the respirator has been tested. If so, and if there is large amount of a toxic chemical in the outside air, fifty-fifty that small leakage can be unsafe.

Can anyone wear a respirator mask?

Breathing through a respirator is harder than breathing in open air. People with lung diseases such as asthma or emphysema, elderly people, and others may have trouble breathing. Some people with claustrophobia may non exist able to wear a mask or hooded respirator. Some people with vision problems may take trouble seeing while wearing a mask or hood (there are special masks for people who demand spectacles).

Volition a gas mask protect children?

There are a variety of bug with fit and use of respirators for children, especially small children and infants. For example, currently available masks are unlikely to fit the faces of minor children and infants. Every bit with respirator use past anybody, fit-testing, preparation, and proper use and maintenance are essential.

Will my cartridge/filter and respirator mask protect forever?

Cartridges, filters, and masks get one-time. Cartridges can accept a express life. If the filter cartridges that attach to the mask are outdated, have been open to the air or are damaged, you are non protected. Cartridges that contain charcoal or other chemicals for filtering the air should exist in air-tight packages. If cartridges are open up or not packed in air-tight packaging, they should non be used. Even cartridges in original packaging accept expiration dates that should be checked before purchase. As well, over fourth dimension your mask can get old and break downward. Keep your mask in a make clean, dry place, away from farthermost heat or cold. Inspect information technology according to the manufacturers instructions.

If I wear a Gas Mask correctly, am I completely safe?

The filter cartridges protect against just certain inhaled airborne substances. Some unsafe chemicals are captivated through the peel. Properly selected and worn gas masks and escape respirators must be combined with protective wearable to completely prevent injury from these chemicals.

Volition a Gas Mask protect me if in that location is not enough oxygen in the air?

Gas Masks do not provide oxygen. If used in an environment with depression oxygen levels, such equally a burn, you are in danger of suffocation.

Will a Gas Mask protect me if there is a burn down?

Information technology's of import to read the manufacturer's data if your main business organization is to exist able to escape from a smoke-filled building. Smoke particles tin can rapidly clog gas mask filters, and filters with special chemicals are needed to protect against carbon monoxide and other gases that may occur in a fire. Not all gas masks and escape respirators protect against these hazards. Some components, including hoods and facepieces, of many of the gas masks and escape respirators may cook if exposed to a fire.

Once I put on my Gas Mask or Escape Respirator, how long will it last?

That depends on how much filtering chapters the respirator has and the corporeality of hazard in the air – the more than chemical or biological run a risk in the air (higher concentration), the shorter the time your filter will concluding. There is no absolute time limit, and it will vary by each respirator model's capacities. That'due south why your emergency plan must include some idea of how to get to a safe area before the filtering capabilities of the mask runs out.

How do I know a respirator will protect me against the hazards it claims to protect against?

No agency in the U.S. tests and certifies respirators for use by the general public, nevertheless, the National Institute for Occupational Safety and Health (NIOSH) function of the Centers for Disease Control and Prevention (CDC), tests and certifies respirators for use past workers to protect against workplace hazards. Respirators certified by NIOSH will say "NIOSH Approved" and may have a certification number. However, NIOSH just certifies respirators against specific hazards. Just because a respirator is certified does non mean it will protect against ALL hazards. NIOSH-certified respirators are supplied with Approval Labels that identify the hazards that the respirator is approved to protect against. If you are ownership a respirator, you should check the Blessing Label to exist sure that it has been certified against the hazards you want protection against.

The Questions You Should Ask Nigh Whatsoever Respirator You Are Because Purchasing

1. What protection (which chemicals and particles, and at what levels) does the escape hood provide?
2. Is there more than than one size?

5. Has the escape hood been tested against claims for protection such every bit biological agents, chemic warfare agents, toxic industrial chemicals, and radioactive dust particles?
6. Who performed the testing, what were the tested levels, and test durations?
7. Is the escape hood certified by an independent laboratory or government agency?
8. Are there whatever special maintenance or storage conditions?
9. Will I exist able to talk while wearing the respirator?
10. Does the hood restrict vision or head motion in whatever way?
11. Can I carry the device in the trunk of my car?
12. Is a preparation respirator available?
13. Can I utilise the escape hood more than one time?
14. Tin can children vesture the escape hood and go the expected protection?
