Breathing Apparatus

Respiratory protection is defined as equipment used to prevent exposure to gases, vapors and particulates by inhalation. The two major categories of breathing apparatus are air purifying respirators (APRs), which use ambient air purified through a filtering element, and atmosphere supplying respirators, which have a separate air source. APRs are commonly used during normal workplace operations, but are not suitable for emergency response situations.

Atmosphere supplying respirators fall into three categories: Self Contained Breathing Apparatus (SCBA), Supplied Air Respirators (SARs), and combination SCBA/SAR. Of these, SCBA provides the highest available level of protection against airborne contaminants and oxygen deficiency. The technology behind SCBA and other respiratory protection is sophisticated, leading to greater protection for the user but also requiring intensive training in the proper selection, use and maintenance.

"Breathing Apparatus" discusses the different types of breathing apparatus and the components of each, as well as safety features, capabilities and limitations. The operation of the equipment, proper techniques for its use, inspection procedures, and emergency operations are demonstrated. Factors which make specific equipment appropriate or inappropriate for particular tasks are explained.

The film teaches about hazardous atmospheres and respiratory hazards. It stresses the need for training in the use of equipment in simulated emergency conditions before the user is exposed to a true emergency. Other topics covered include donning and doffing the various types of breathing apparatus, cylinder changeout and recharging, fit testing, open circuit versus closed circuit SCBA, the importance of physical conditioning, maintenance of equipment, and the special problems of hazmat incidents. Actual demonstrations of how the components fit together and operate are particularly helpful.

The program includes a 60-page Leaders Guide which outlines a comprehensive six-hour training program in the selection, use and care of breathing apparatus. Objectives of the program, field and classroom exercises, and pre- and post-tests are included, as well as a copy of the script for the Leaders' reference.
