How long is the lifespan for carbon fiber cylinders?

The correct choice indicates that carbon fiber cylinders typically have a lifespan of 15 years. This timeframe is established based on industry standards, which dictate the safe operational life for composite pressure vessels like carbon fiber cylinders. These materials provide a high strength-to-weight ratio and are used in applications requiring lightweight and strong containers for gases, such as in fire protection systems.

After 15 years, the integrity of these cylinders can degrade due to environmental factors, usage conditions, and the inherent properties of the materials. Regular inspection and adherence to maintenance schedules are critical to ensure safety. However, after reaching this designated lifespan, the cylinders must be retired from service to prevent any risk of ruptures or failures, ensuring the safety of personnel and equipment.

Understanding these safety standards is essential for fire protection professionals, as it helps maintain operational readiness and safety compliance.
