Supplied-air respirators (airline respirators) supply air to a facepiece via a supply line (hose) from a stationary source. SARs are available in positive-pressure and negative-pressure modes. Pressure-demand SARs with escape provisions provide the highest level of protection and are the only SARs recommended for use at hazardous waste sites. SARs are not recommended for entry into IDLH atmospheres unless the apparatus is equipped with an escape SCBA. The air source for supplied-air respirators may be compressed air cylinders or a compressor that purifies and delivers ambient air to the facepiece. All SAR couplings must be incompatible with the outlets of other gas systems used on site to prevent a worker from connecting to the wrong gas source (nitrogen, hydrogen, etc.). 

Our complete line of respiratory protection equipment includes powered air purifying respirators, airline respirators, pressure demand systems, supplied air filters and monitors, and a full range of breathing air pumps. Bullard respiratory products meet NIOSH standards and provide high-quality protection to workers in the Healthcare, Pharmaceutical, Painting, Blasting and Grinding industries.

Respirators protect the user in two basic ways. The first is by the removal of contaminants from the air. Respirators of this type include particulate respirators that filter out airborne particles and gas masks that filter out chemicals and gases. Other respirators protect by supplying clean respirable air from another source. Respirators that fall into this category include airline respirators that use compressed air from a remote source and self-contained breathing apparatus (SCBA) that include their own air supply. 

This type of respirator supplies clean air from cylinders that you carry, usually on your back. This lets you move more freely and over a wider area than you can with a supplied-air respirator. Get training from competent instructors before using any type of respiratory protection, especially self-contained breathing equipment. These devices contain a limited air supply (usually about 30 minutes), which may be used up even more quickly in high temperatures or with excessive exertion. Figure 6.13 shows the different air-supplying respirators, the airline and self-contained breathing apparatus.

When opening the reactor manway, there is a potential for exposure to toluene and benzene. An airline respirator must be worn. 

Operator must be qualified in use of airline type III respirators. 

Type C Respirator An airline respirator, for entry into and escape from atmospheres not immediately dangerous to life or health, which consists of a source of respirable breathing air, a hose, a detachable coupling, a control valve, orifice, a demand valve or pressure demand valve, and arrangement for attaching the hose to the wearer and a facepiece, hood, or helmet. 

A supplied-air respirator approved by the Mine Safety and Health Administration (MSHA) and/or NIOSH. Respirators may be pressure-demand, self-contained breathing apparatus (SCBA) or a pressure-demand, airline with escape bottle for immediately dangerous to life and health (IDLH) or potential IDLH atmosphere. 

Respirators with an air source are called air-supplied respirators and consist of two types, the (1) SCBAs which gets its air supply from a source (tank or bottle) carried by the user, and (2) the SAR, which is connected to the user by an air hose connected to a distant air supply. It is sometimes referred to as an airline respirator.

Atmosphere supplying respirator— Any respirator that provides clean air from an uncontaminated source to the face piece examples include supplied-air (airline) respirators, self-contained breathing apparatus (SCBA), and combination supplied air/SCBA devices. 

Supplied-air respirator (SAR)—A respirator that provides breathing air throngh an airline hose from an uncontaminated compressed air source to the face piece. The face piece can be a hood, hehnet, or tight-fitting face piece. 

For occasional jobs of limited duration, where an operator may need to carry out minor touch-up work or needs to enter a spray area for quality control inspection purposes, etc., it is accepted that a full canister respirator complying with BS 2091 (1969) and fitted with a type CC canister may be worn provided that the facepiece is a correct fit and that the canister is changed after successive brief periods totalling 15 min spraying, or otherwise in accordance with the makers instructions. The use of a canister respirator is, however, considered to be very much a second choice in comparison with the superior protection afforded by a continuous flow airline breathing apparatus. Firm controls must be exercised to ensure that the conditions attached to the use of canister respirators are fully observed. 

Those applying the lining should wear fresh airline respirators and protective cream on exposed parts of the body. Water should be available for flushing accidental spills from the skin. Never allow one worker in the tank alone. 

Supplied-air respirator (SAR) or airline respirator means an atmosphere-supplying respirator for which the source of breathing air is not designed to be carried by the user. 

A) Assigned Protection Factors (APFs) Employers must use the assigned protection factors listed in Table 1 to select a respirator that meets or exceeds the required level of employee protection. When using a combination respirator (e.g., airline respirators with an air-purifying filter), employers must ensure that the assigned protection factor is appropriate to the mode of operation in which the respirator is being used. 

Conduct air quality tests annually on internal combustion engine-driven airline respirator compressors to ensure proper air quality. 

Ensure inspection of cartridge-type respirators on a monthly basis and self-contained breathing apparatus (SCBA) and airline hose mask systems on a weekly and monthly basis. Ensure that records of respirator inspections are maintained. Ensure that employees are fit tested and receive initial and annual spirometric evaluation prior to using a respirator.

Description— These devices provide air to the wearer through a small-diameter, high-pressure hose line from a source of uncontaminated air. The source is usually derived from a compressed airline with a valve in the hose to reduce the pressure. A filter must be included in the hose line (between the compressed airline and the respirator) to remove oil and water mists, oil vapors, and any particulate matter that may be present in the compressed air. Internally lubricated compressors require that precautions be taken against overheating, as the heated oil will break down and form carbon monoxide. Where the air supply for airline respirators is taken from the compressed airline, a carbon monoxide alarm must be installed in the air supply system. Completion of a prior-to-operation preventive maintenance check on the carbon monoxide alarm system is critical. 

Application— Airline respirators used in industrial applications for confined space entry (IDLFi atmosphere) must be equipped with an emergency escape bottle. 

Workcenter supervisors shall ensure that all cartridge-type respirators are inspected once per month and make appropriate entries in a "Supervisor s Monthly Respirator Inspection Checklist." The work center supervisor or designated person shall inspect all SCBA and airline respirators weekly and monthly, and make appropriate entries in a "SCBA/Airline...
