A fixed CO2 system on a MODU with a capacity of over 300 lbs (136 kilograms) CO2 which protects spaces other than tanks must have
AI Explanation
The correct answer is D) an audible alarm and time delay.
The reasoning for this is that fixed CO2 systems with a capacity over 300 lbs (136 kg) protecting spaces other than tanks are required to have an audible alarm and a time delay before automatic release. This allows personnel to evacuate the protected space before the CO2 is released, preventing injury.
The other options are incorrect because: A) is missing the time delay requirement, B) is not a requirement for this size system, and C) automatic release without an alarm and time delay would be unsafe.
