Which of the following is a limitation of SCBA?

The limitation of self-contained breathing apparatus (SCBA) highlighted in this context refers to the issue of low air cylinder pressure. SCBA is designed to supply firefighters with breathable air in hazardous environments, but if the air cylinder is not adequately pressurized, it can limit the duration for which the firefighter can use the equipment effectively. Low air pressure means that the air supply is insufficient for the tasks at hand, which can put firefighters at risk during operations, particularly if they are in an environment where conditions can change rapidly.

While firefighters rely on SCBA for a variety of benefits, such as improved visibility due to the face piece, enhanced communication with specific models, and improved mobility with ergonomic designs, low air cylinder pressure remains a critical limitation that can affect safety and operational effectiveness. It emphasizes the importance of routinely checking and maintaining air supply levels before entering hazardous areas.
