70% to passThe passive safety device installed on each Halon fire extinguishing cylinder, to prevent its over pressurization is called a _______________.
Arelief valve
Brupture disc
Ccontrol head
Dsafety valve
AI Explanation
The correct answer is B) rupture disc. The rupture disc is the passive safety device installed on each Halon fire extinguishing cylinder to prevent over-pressurization. Rupture discs are designed to burst at a specific pressure, relieving the cylinder's internal pressure before it reaches a dangerous level. This safety mechanism helps to prevent the cylinder from rupturing or exploding in the event of an internal pressure buildup. The other options are incorrect because: A) a relief valve is an active safety device that opens at a set pressure, C) the control head does not provide over-pressurization protection, and D) a safety valve is a different type of pressure relief mechanism.
