There is no other risky occupation like firefighting and rescuing people from hostile environments particularly when the breathing air gets poisoned. In order to reduce exposure to this danger and execute their mission successfully, firefighters use special equipment, one of which is the self contained breathing apparatus, widely known as firefighter SCBA. The term self contained is used to signify that it independent from remote air supply.
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.
The firefighter SCBA normally put emphasis on flame and heat resistance which is more important that even the overall cost. The light weight materials used to manufacture these devices are normally exotic making the final cost very expensive. Personal Alert Safety System (PASS) or Automatic Distress Signal Unit (ADSU) is never missing components of the modern equipment. These are designed to switch on automatic after sensing no movement after 15 to 30 seconds. When activated, they release distinctive alarm signal that helps to locate the user. They can also be activated manually.
The success on the use and overall rescue mission depends on how well the user is familiar with this important device. In fact, continuous drill is always recommended as the device can make a difference between life and death. For a successful drill, the near fatalities and other past failures that involved the equipment use forms the starting point during training.
The most important and common drills that should be considered include the SCBA check where the operational readiness is examined, the consumption drill targeting to determine the period a particular bottle will last for a given user and the last-breath drill that is more concerned with confidence and accuracy.
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.
