What safety feature should be utilized when installing gas appliances?

Manual shut-off valves
Pressure gauges
Fire extinguishers
Ventilation systems

The correct answer is: Manual shut-off valves

Utilizing manual shut-off valves during the installation of gas appliances is essential for ensuring safety. These valves provide a quick and reliable method to stop the flow of gas in the event of a leak or malfunction. Having a manual shut-off feature allows for immediate action to prevent potential hazards, such as explosions or asphyxiation, in situations where gas might escape. This safety measure is crucial for both the installer and the occupants of the building, as it helps to manage risks associated with gas appliances effectively. While pressure gauges, fire extinguishers, and ventilation systems are important components in the context of gas safety, they serve different purposes. Pressure gauges monitor gas pressure levels, which is important for system functionality but does not provide a direct means to halt gas flow. Fire extinguishers are vital for addressing emergencies if a fire occurs but do not prevent the onset of leaks. Ventilation systems are necessary for ensuring that gas appliances operate safely by removing harmful gases, yet they do not provide an immediate means to shut off gas supplies when needed.
