What is the increased weight experienced while wearing a Self-Contained Breathing Apparatus (SCBA)?

When wearing a Self-Contained Breathing Apparatus (SCBA), one experiences an increase in weight primarily due to the components of the apparatus itself, which includes the tank, regulator, and harness. The correct answer, indicating an increase of 30 pounds, reflects the typical combined weight of the SCBA system when filled with air and ready for use. This added weight impacts the firefighter's mobility and stamina, necessitating adjustments in their physical readiness and technique during emergency operations.

Understanding the weight of the SCBA is crucial for firefighters, as it influences their overall physical demand and endurance while performing their duties. Proper training and conditioning are essential to cope with the added weight effectively, allowing firefighters to carry out their responsibilities safely and efficiently.
