What benefit is associated with an air line respirator?
Advantages: Airline respirators may be used for long periods of time and provide a high degree of protection from a variety of air contaminants. they provide minimal breathing resistance and discomfort, are light weight, low bulk, moderate initial cost and low operating costs.
What type of respirator uses an airline?
Airline Respirators. Airline respirators, or supplied air respirators (SAR), are used when air purifying respirators cannot provide sufficient protection against airborne or chemical contaminants.
Are airline respirators air purifying?
Duo-Twin Airline Respirator This combination air-supplied/air-purifying respirator is designed for use with either particulate filters and/or chemical cartridges. Provides respiratory protection against a variety of contaminants, making it popular for pharmaceutical, chemical, petrochemical and nuclear industries.
What is the primary advantage of a supplied air respirator?
1. The respirator is much more protective because it provides positive pressure in the facepiece and almost all leakage is outward. A positive-pressure supplied-air respirator should be used when disposable respirators, replaceable respirators, or PAPRs do not provide adequate protection.
What is the main purpose of a respirator?
A respirator is designed to protect the wearer from inhaling airborne contaminants such as dusts, fumes, vapors, and infectious agents associated with inhaling small and large particle droplets; guidance on appropriate selection and use is covered by OSHA's respiratory protection and PPE standards.
What do air supplied respirators provide?
clean breathing airAtmosphere-supplying respirators provide clean breathing air from a source independent of the work area. These respirators will protect wearers from many types of airborne contaminants (particles, gases, and vapors) and, in certain cases, oxygen-deficient atmospheres.
Does air-purifying respirator provide oxygen?
Air-purifying respirators function by filtering contaminants from the air. They do not supply oxygen to the wearer. Air-purifying respirators can only protect at or below specific concentrations of contaminants.
What are the three types of respirators?
FFRs are disposable respirators that cover the nose and mouth. Elastomeric full facepiece respirators are reusable and cover the nose, mouth, and eyes. PAPRs are reusable and often have a hood or helmet that covers the nose, mouth, and eyes. A battery-powered blower pulls air through filters or cartridges.
When should a supplied-air respirator be used?
Supplied-Air Respirators They are sometimes referred to as airline respirators. At a minimum, the breathing air must meet the requirements for Grade D breathing air. 2 They can be lightweight and used for long, continuous periods in atmospheres that are not immediately dangerous to life and health (IDLH).
What is a major disadvantage of supplied-air respirators?
The main disadvantage of negative-pressure respirators is that if any leaks develop in the system (i.e., a crack in the hose or an ill-fitting mask or facepiece), the user draws contaminated air into the facepiece during inhalation.
Which respirator will provide a positive pressure air supply over a long period of time?

What is the best air source for a high pressure air respirator?
The air source for a high pressure airline respirator often requires an air filtration system to provide Grade D air, and it is important to monitor the user’s carbon monoxide level. Air cylinders, or bottled air, are another source of high pressure breathing air.
What are the different types of SAR respirators?
Types of SAR respirators. 1. Tight Fitting Full-face and Half-mask Respirators – These respirators are used in IDLH situations and when gases and vapors are present that APR’s cannot protect against. Fit testing is required when using a negative or positive pressure tight fitting mask. 2.
What is grade D air?
According to OSHA, compressed air must meet the requirements of the Compressed Gas Association (CGA) specifications of Grade D breathing air. Grade D breathing air can come from an ambient air pump, an air compressor or plant air, which can be filtered and regulated.
Isn't an Airline Respirator for More Dangerous Situations?
The answer to this is both "yes" and "no". Let's consider a hazard that might typically be present in a confined space: hydrogen sulfide (H2S).
How To Determine When an Airline Respirator Is Needed
The method for determining when an airline respirator is required, inconveniently, is to know at least two things. (1) What the hazard is. (2) How much of the hazard is present. It then requires that you consult the NIOSH Chemical Hazard Guide armed with this information and look up the hazard you are facing.
How do you know how much hazard is in the air?
In the case of H2S, the answer to this is relatively simple to find out. All you need is one of our 4-gas confined space monitors. These monitors will give you a PPM readout of 4-gases, including H2S.
Important Tip
In the case of H2S in a confined space, it must be noted that ventilation of the space with a confined space blower may eliminate the need for any breathing protection. This is one of the purposes of a confined space blower.
What is the MUC?
MUC stands for Maximum Use Concentration. In the case of our H2S example, the NIOSH Guide notes that the MUC for H2S is 100 PPM. This happens to be the same as the IDLH for H2S. The two, however, aren't always the same.
Conclusion
So download the NIOSH Chemical Guide and you will be well on your way to understanding when an airline respirator is required. Feel free to email us any questions at [email protected]. We are always glad to help. Be sure to check out our selection of airline respirators.
