Question

Which ONE of the following is NOT a primary safety system for offshore installations?

• A. Emergency Shut Down
• B. Isolation
• C. Fire Protection
• D. Blowdown

Hint:

Primary safety systems like ESD, Isolation, and Blowdown directly control hazards and prevent accidents. Fire protection, while vital, is a secondary response system.

Answer 1

The Correct Option is C

In offshore installations, there are primary and secondary safety systems. Primary safety systems are those that are immediately involved in preventing accidents, controlling hazardous conditions, and mitigating risks. The primary safety systems include: 1. Emergency Shut Down (ESD): The ESD system is a critical safety measure that immediately halts all operations if a dangerous condition is detected, preventing further escalation of risk. 2. Isolation: This system involves isolating hazardous materials or processes to prevent the spread of dangerous substances or conditions. It is used when it is necessary to isolate equipment to minimize potential risks. 3. Blowdown: Blowdown systems are used to safely release pressure or gas from pressurized systems, ensuring that pressure does not build up to dangerous levels that could result in catastrophic failure. Fire protection, on the other hand, is generally considered a secondary safety system. While it is essential, it is primarily a response system designed to manage a fire once it has occurred, rather than a preventive or control mechanism in the way that ESD, Isolation, and Blowdown systems function. Thus, fire protection is not a primary safety system but a secondary one.
