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.
The basic components of a firefighter SCBA include a high pressure tank of breathing air, the insulated connecting pipes and a pressure regulator. The modern ones are more efficient with many additional features the most common being a face mask and lighter tank. The general design must allow for shoulder-carrying of victims with no hindrance. It must also allow for uninterrupted air flow no matter the environmental conditions.
In Europe, any supplier of SCBA devices is required to comply with Personal Protective Equipment Directive (89/686/EEC) requirements which are basically the reinforcement of European Standard EN 137: 2006 requirements. This normally details for performance, markings and the information given to the users. If the equipment is fully compliant and reliably operates at the range of -30C to +60C with different and severely stimulated conditions gets certification of approval.
In the United States and Canada, the situation is not different. The requirements are almost similar. The guidelines to be met are those of the National Fire Protection Association (NFPA Standard 1981) which are usually revised after every five years. The 1981 NFPA label is normally an indication of a compliant device. The National Institute for Occupation Safety and Health (NIOSH) also give certification particularly in the areas of chemical, biological, nuclear and radiological 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.
The success in use of this important equipment however depends on how often you conduct SCBA drills. No matter the level of training or experience, mastering these devices still requires continuous drill, effort and personal commitment. During drills, the starting point is usually the past fatalities or misuse in the device use or air management. These incidents are important information source that can help prevent similar situations in the future. Online information from trusted websites can also help in these drills.
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.
The rescue operation is simply impossible without firefighter SCBA. This device makes the difference between life and death both to the users and victims alike. For this reason, every firefighter must be engaged in continuous training and drilling in order to be able to operate it accurately when the need arise,
