Question 244Safety & Environmental - QMED70% to pass
The passive safety device installed on each Halon fire extinguishing cylinder, to prevent its over pressurization is called a _______________.
AI Explanation
The correct answer is C) rupture disc.
A rupture disc is a passive safety device installed on Halon fire extinguishing cylinders to prevent over-pressurization. The rupture disc is designed to rupture at a specific pressure, relieving the internal pressure and preventing the cylinder from bursting. This is a regulatory requirement for Halon fire extinguishing systems, as specified in various fire protection standards.
The other options are incorrect because: A) a safety valve is an active device that opens at a set pressure, B) a control head is the mechanism that releases the Halon from the cylinder, and D) a relief valve is a different type of pressure-relief device that opens and closes, unlike the one-time rupture disc.
