On offshore drilling units where foam systems are installed on the heliport, the system must be able to discharge continuously for at least _______________.
AI Explanation
The correct answer is A) 5 minutes.
The requirements for foam fire-extinguishing systems on offshore drilling units are specified in Title 46, Code of Federal Regulations (CFR), Section 108.489. This regulation states that the foam system must be capable of discharging foam continuously for at least 5 minutes. This ensures that the foam system can effectively suppress any fire on the heliport for a sufficient duration.
The other options, such as 6 minutes, 8 minutes, or 10 minutes, are incorrect because they do not meet the minimum requirement of 5 minutes as per the regulations.
