The self-contained breathing apparatus, or SCBA, is a respiratory protective device that is used to provide breathable air in situations where the atmospheric air is either inadequate or dangerous. It has a face mask, an air supply system, and cylinders of compressed air that enable a person to work in an environment full of toxic gases, smoke, or low oxygen levels, such as firefighting, industrial safety, and rescue missions. Furthermore, a few driving forces behind the SCBA market are rising demands for protection and safety in hazardous operating environments, particularly within firefighting and industries.
