What is the limitation of an SCBA?

The primary limitation of a Self-Contained Breathing Apparatus (SCBA) is its limited air supply, which restricts the duration of use to a few hours depending on the cylinder size and demand. Additionally, SCBAs can be bulky and heavy, potentially hindering mobility and comfort during extended operations. They also require proper training and maintenance to ensure effective operation and safety. Lastly, SCBAs do not filter air, making them unsuitable in environments with toxic gases or low oxygen levels without an adequate air supply.
