What Is a Self-Contained Breathing Apparatus (SCBA)
A Self-Contained Breathing Apparatus (SCBA) is a device designed to supply breathable gases, such as oxygen or air. These apparatuses are essential in firefighting, construction, manufacturing, and agriculture, protecting environments from oxygen deficiency or harmful gases, dust, and other risks. They are recognized for their portability and ease of operation, enabling safe work in challenging conditions.
In SCBAs, the air inhaled through the breathing tube is purified by a filter and supplied from a cylinder through an inhalation valve. The exhaled air is then released through an exhalation port. The apparatus typically consists of a cylinder containing compressed air or oxygen, which is delivered to the user via a mask or helmet.
SCBAs are categorized into two main types: air respirators and oxygen respirators. Advanced models may include features like alarms, communication systems, and display functions for enhanced safety and usability.
