The Role Of Firefighter SCBA In Firefighting

By Judy Sullivan


Firefighting is a very risky job and requires special skills and special equipment. There is normally no breathable air in such environments making the rescue without a breathing aid impossible. To make the situation bearable, a device known as self contained breathing apparatus or firefighter SCBA is normally used for as a breathing aid. This device is independent from external supplies hence the risk of getting tangled is greatly reduced.

A basic self contained breathing apparatus comes with three distinct parts. These are a high pressure air tank, a pressure regulator and an insulated connecting. Just like the helmet and the suit, this device is a matter of life and death to a firefighter. The modern gadgets have improvements including face mask and are generally much lighter to carry around. The stainless air tank and the rest of components are designed to allow for continuous air flow in every environment.

In order to ensure that these devices performs optimally and do not fail as that could be catastrophic, several regulatory authorities have put in place specific standards that the suppliers must meet in order to have their supplies certified. The European manufactures and supplies have to comply with Personal Protective Equipment Directive (89/686/EEC) requirements, extensions of European Standards EN 137: 2006 detailing the expected level of performance, markings and user information. The operating temperature range for devices for example must be at least -30C to +60C in a very stimulated environment reflecting the real fire situation.

The situation is not quite different in the United States of America and Canada where these devices must meet National Fire Protection Association guidelines, NFPA Standard 1981. When fully compliant with firefighting requirements, it earns 1981 NFPA compliant label. In addition to this, the National Institute for Occupational Safety and Health (NIOSH) have their own certification program designed for use in biological, chemical, radiological and nuclear environment.

On the design of a firefighter SCBA, the emphasis is more on the heat and flame resistance ability rather than cost. This has to do will their significance in life saving. Most of manufacturing devices must be light enough in addition to fire resistance and are in most cases exotic and very expensive. The modern ones have Automatic Distress Signal Units (ADSU) or Personal Alert Safety System (PASS) which get activated automatically when there is no evidence of movement between 15-30 seconds or manually if the user is in danger to assist on the search.

Given their complexity particularly in a panic mode, it is important that every potential user is engaged on continuous drill regardless of level of training and experience. This is particularly because these devices mean life or death to firefighters. Thinking of past failures and fatalities normally give the starting point for the drills.

The drill must be comprehensive covering areas such as SCBA check examining the operational readiness of a particular equipment, the consumption drill which determines for how long a particular bottle will last the user the last breath-drill concerning confidence in a panic mode among others.

Firefighter SCBA can be the difference between life and death to firefighters. This means that the users must be well trained on operating them. In the practical sense, no amount of training can be considered enough, this therefore calls for continuous drilling. The sourcing of the equipment must also be done from certified suppliers.
