In what position should the gas cock be to turn off the gas?

To turn off the gas, the gas cock should be positioned perpendicular to the flow of the gas. This positioning effectively cuts off the gas supply, ensuring that no gas can pass through the valve. When the valve is perpendicular to the piping, it is in a closed state, preventing the flow of gas to appliances or equipment connected downstream.

In most gas systems, the configuration is standardized, making it essential for safety and compliance with fire service protocols. Understanding the correct orientation of gas cocks is vital for firefighters and emergency responders since improper handling can lead to dangerous gas leaks or explosions. Recognizing this positioning is crucial during emergency situations where shutting off gas supplies quickly and efficiently could mitigate further hazards.
