What is the maximum time allowed for firefighters to don and activate an SCBA?

The correct choice indicates that firefighters are trained to don and activate a Self-Contained Breathing Apparatus (SCBA) within a maximum of one minute. This requirement is critical for ensuring safety and efficiency during emergency response situations, particularly in environments where hazardous atmospheres may be present.

The one-minute timeframe is designed to ensure that firefighters can quickly equip themselves with the necessary protection to enter dangerous zones without delaying their response to a potential life-threatening situation. Rapid donning of SCBA is essential to maintain operational effectiveness, especially in scenarios involving smoke, toxic gases, or other immediate hazards. Training and drills often emphasize quick deployment to instill this practice and ensure readiness in real-life emergencies.

In contrast, the other time limits provided in the options might not be as practical or reflective of established protocols. While options such as 2 minutes, 30 seconds, and 90 seconds suggest varying levels of urgency, the one-minute standard strikes a balance between speed and thoroughness necessary for the safety of firefighters.
