Breathing Apparatus

Product Details:

A self-contained breathing apparatus (SCBA), sometimes referred to as a compressed air breathing apparatus (CABA) or simply breathing apparatus (BA), is a device worn to provide breathable air in an atmosphere that is immediately dangerous to life or health. They are typically used in firefighting and industry. The term self-contained means that the SCBA is not dependent on a remote supply of breathing gas (e.g., through a long hose). If designed for use under water, it is also known as a Scuba set (self-contained underwater breathing apparatus). When not used underwater, they are sometimes called industrial breathing sets. Unofficial names include air pack, air tank, oxygen cylinder or simply pack, which are mostly used in firefighting.

An SCBA typically has three main components: a high-pressure tank (e.g., 2,216 to 5,500 psi (15,280 to 37,920 kPa), about 150 to 374 atmospheres), a pressure regulator, and an inhalation connection (mouthpiece, mouth mask or face mask), connected together and mounted to a carrying frame.^[1]

A self-contained breathing apparatus may fall into one of two categories: open-circuit or closed-circuit.^[2]

There are two major application areas for SCBA: firefighting and industrial use.^{[citation needed]} A third use now coming into practice is medical; for example, the American National Institutes of Health prescribe use of SCBAs for medical staff during treatment of ebola.

For firefighting, the design emphasis is on heat and flame resistance above cost. SCBAs designed for firefighting tend to be expensive because of the exotic materials used to provide the flame resistance, and to a lesser extent, to reduce the weight penalty on the firefighter. In addition, modern firefighting SCBAs incorporate a PASS device (personal alert safety system) or an ADSU (automatic distress signal unit) into their design. These units emit distinctive, high-pitched alarm tones to help locate firefighters in distress by automatically activating if movement is not sensed for a certain length of time (typically between 15 and 30 seconds), also allowing for manual activation should the need arise. In firefighting use, the layout of this breathing set should not interfere with ability to carry a rescued person over the firefighter's shoulders.

The other major application is for industrial users of various types. Historically, mining was an important area, and in Europe this is still reflected by limitations on use in the construction of SCBAs of metals that can cause sparks. Other important users are petrochemical, chemical, and nuclear industries. The design emphasis for industrial users depends on the precise application and extends from the bottom end which is cost critical, to the most severe environments where the SCBA is one part of an integrated protective environment which includes gas-tight suits for whole-body protection and ease of decontamination. Industrial users will often be supplied with air via an air line, and only carry compressed air for escape or decontamination purposes.

The Dräger PSS® 3000 is a new generation of high-performing breathing
apparatus for industrial applications. Combining comfort with exceptional
performance, it is designed for applications where simplicity and ease-ofuse are essential. Lightweight yet robust, and easy to wear, this advanced
breathing apparatus provides the ultimate breathing protection.
Dräger FPS® 7000 (NFPA 2013 Edition)
Firefighting requires working under hazardous conditions with poor
visibility. Designed to offer optimal visibility, the Dräger FPS 7000 full
face mask sets new standards in terms of personal safety, protection
and comfort. The popularity of this SCBA mask is due to a large,
unobstructed field of vision and a very comfortable and secure fit, while
reducing or eliminating fogging during use.

Product Details:

The MSA Airxpress Breathing Apparatus EN 137 first-stage pressure reducer is the same one used in all MSA systems. Thispatented and choice component distinguishes itself through reduced parts and low maintenance, which translates into reduced cost of ownership. Like all other MSA SCBA systems, all components on the AirXpress are designed to last long in rugged circumstances. They are EN 137:2006 approved to withstand high temperatures, flames and rough handling plus they are intrinsically safe and ATEX-approved for zone 0 environments.
