According to the regulations, what fire safety control feature is required in quick- closing shut off valves?

A A fusible link
B A water spray actuator
C Electrical cut off switch
D Manual cut off switch
AI Explanation

The correct answer is A) A fusible link. According to the regulations, quick-closing shut-off valves used for fire safety control must be equipped with a fusible link that will automatically close the valve in the event of a fire. The fusible link is designed to melt at a predetermined temperature, triggering the valve to shut off the fuel or gas supply to prevent the spread of the fire. The other options, such as a water spray actuator, electrical cut-off switch, or manual cut-off switch, are not required features for these types of quick-closing shut-off valves per the regulations.
