Question 94Safety & Environmental - QMED
70% to passWhich unit will provide excellent mobility to the wearer in an unsafe atmosphere and provide oxygen to sustain life?
AA self-contained breathing apparatus
BAn ammonia gas mask
CA fresh air breathing apparatus
DAll of the above
AI Explanation
The correct answer is A) A self-contained breathing apparatus (SCBA). A SCBA provides excellent mobility and delivers oxygen to the wearer, allowing them to safely operate in unsafe atmospheres where the normal air supply may be contaminated or oxygen-deficient. This type of equipment is essential for Coast Guard personnel who may need to respond to hazardous spills, fires, or other emergency situations. The other options are incorrect - an ammonia gas mask is designed for a specific type of chemical exposure, while a fresh air breathing apparatus relies on a remote, uncontaminated air supply which would limit mobility and access in an unsafe atmosphere.
