At what percentage of rated pressure will a cylinder no longer qualify for service?

• A. 100%
• B. 110%
• C. 120%
• D. 130%

Answer: (B)

A cylinder is required to maintain a certain percentage of its rated pressure to be deemed safe and qualified for service. When a cylinder drops below a specific pressure threshold, it is no longer considered safe for use and must be taken out of service. The correct answer indicates that a cylinder must retain at least 110% of its rated pressure to qualify for service. This percentage ensures that the cylinder maintains sufficient pressure for effective operation and helps prevent potential issues during use, such as insufficient performance or safety hazards. If the pressure falls below this threshold, it may signal that the cylinder has deteriorated or could pose a risk if used under operational conditions. Understanding this aspect is crucial for safety regulations and ensuring that equipment intended for fire suppression remains reliable and effective, ultimately protecting lives and property in emergency situations.
