70% to passPrior to entering a compartment containing an atmosphere potentially dangerous to life or health and deficient in oxygen, you should don an approved breathing apparatus. Which of the listed devices would be suitable?
AAn SCBA.
BA canister-type gas mask.
CAn emergency escape hood.
DA filter-type mask.
AI Explanation
The correct answer is A) An SCBA (Self-Contained Breathing Apparatus). Before entering a compartment with a hazardous atmosphere, an SCBA is the appropriate approved breathing apparatus to use. An SCBA provides a portable supply of clean, breathable air, which is essential when the surrounding atmosphere is deficient in oxygen or contains toxic gases. The other options, such as a canister-type gas mask, emergency escape hood, or filter-type mask, do not provide a self-contained air supply and would not be suitable for this situation.
