Which type of respiratory protection is preferable for the repair/investigation personnel in a hydrogen sulfide (H2S) environment?
AI Explanation
The correct answer is C) Positive Self-Contained Breathing Apparatus (SCBA).
In a hydrogen sulfide (H2S) environment, a positive SCBA is the preferable respiratory protection for repair/investigation personnel. SCBA provides a self-contained, independent air supply that completely isolates the user from the hazardous atmosphere, allowing them to safely operate in the H2S-contaminated area. The positive pressure design of SCBA also helps prevent the infiltration of the toxic gas.
The other options, such as EEBA, OBA, and SCDBA, are not suitable for this application as they either have limited air supply or rely on the surrounding atmosphere, which would be contaminated with H2S.
