Q

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

🔍 Key Concepts

• Quick-closing shutoff valves are designed to stop fuel or flammable liquid flow in a fire emergency • Some valves must operate automatically when exposed to high heat, without human action • Think about common fire‑safety activation methods used on fuel oil lines near engines and tanks

💭 Think About

• Which option describes something that would react by itself when there is a fire, even if no one is present? • Which device is commonly made to melt or change shape at a specific temperature to trigger a safety action? • Which choices would require a person to be present and think to operate them, instead of being heat‑activated automatically?

✅ Before You Answer

• Verify which choice is a passive, heat‑sensitive device used in many fire‑safety systems (like sprinklers or fuel shutoffs). • Eliminate any option that requires manual operation by a crew member in order to stop the flow. • Confirm that the correct feature is specifically mentioned in fire‑safety and fuel shutoff valve requirements in CFR/flag‑state rules.
