천연가스에 불이 붙었을 때 가장 먼저 꺼야 할 것

Prior to tackling a natural gas fire, shutting off the natural gas valve is a critical first step.

Should the valve be damaged and inoperable, focus on extinguishing the fire before attempting to close the valve.

In instances of gas fires, immediate action is required: calling the fire department for emergency response and contacting the gas supply company to disconnect the gas source and facilitate necessary repairs.
