Final answer:
After transmitting a MAYDAY report, a firefighter should immediately activate the PASS device. Self-rescue should also be attempted if possible, but activating the PASS device takes priority. Moving towards the exit in increments of twenty feet (6 m) at a time is also recommended. So, the correct answer is option a.
Step-by-step explanation:
After transmitting a MAYDAY report, a firefighter should immediately activate the PASS device. PASS stands for Personal Alert Safety System, and it is a device worn by firefighters that emits a loud audible alarm if the firefighter becomes motionless for a certain period of time. This is done to alert other firefighters to their location and potential distress.
Self-rescue should also be attempted if possible, but activating the PASS device takes priority. Self-rescue refers to actions taken by a firefighter to get themselves out of a dangerous situation, such as finding an exit or calling for help.
Moving toward the exit in increments of twenty feet (6 m) at a time is also a recommended action, but it should be done after activating the PASS device and assessing the situation. This allows the firefighter to make progress towards safety while maintaining contact with their team and monitoring their own safety. So, the correct answer is option a.
