What additional precautions should be taken when making temporary repairs to a MODU that is operating when hydrogen sulfide is present?
AI Explanation
The correct answer is A) Provide respiratory protection and monitoring.
When making temporary repairs to a MODU (Mobile Offshore Drilling Unit) that is operating with the presence of hydrogen sulfide, the primary precaution is to ensure the safety of personnel. Hydrogen sulfide is a highly toxic gas, so providing respiratory protection such as self-contained breathing apparatus and continuously monitoring the gas levels is crucial to protect workers from exposure. The other options, such as removing bulk materials or sealing off ventilation, do not directly address the primary hazard of hydrogen sulfide inhalation, which is why A is the correct answer.
