Question 928Deck Safety70% to pass
To safely enter a compartment where CO2 has been released from a fixed extinguishing system, you should _______________.
AI Explanation
The correct answer is C) wear a self-contained breathing apparatus.
To safely enter a compartment where CO2 has been released from a fixed extinguishing system, you must wear a self-contained breathing apparatus (SCBA). This is because the CO2 discharge has depleted the oxygen in the compartment, and using a canister type gas mask or testing the air with an Orsat apparatus or pure air indicator would not provide the necessary respiratory protection. Regulations require the use of a SCBA in such oxygen-deficient atmospheres to ensure the safety of the personnel entering the compartment.
The other answer choices, while related to gas detection and respiratory protection, do not provide the level of protection needed when entering a space where CO2 has been discharged, as they do not supply the user with a self-contained source of breathable air.
