What is one limitation of self-contained breathing apparatus (SCBA) that firefighters should recognize?

One limitation of self-contained breathing apparatus (SCBA) that firefighters should recognize is the additional weight it adds, approximately 60-70 pounds. This significant weight can impact a firefighter's mobility and endurance during operations. It's essential for firefighters to be aware of this limitation, as it influences how they manage their physical exertion, maintain stamina, and navigate through various environments while wearing the SCBA. Recognizing this factor helps firefighters to be better prepared and plan for the physical demands of their duties, ensuring they can perform efficiently and safely in emergency situations.
