When the electric meter box catches fire, the following measures can be taken to prevent the fire from spreading to other places:

Immediately cut off the power supply: If a fire is found in the meter box, the main power supply should be quickly cut off to prevent current from fueling the fire or causing electric shock hazards.

Use appropriate fire extinguishing equipment: After confirming that the power has been cut off, dry powder fire extinguishers or gas fire extinguishers can be used for initial fire extinguishing. If conditions permit, sand can also be used as an alternative fire extinguishing material.

Avoid using water to extinguish fires: It is strictly prohibited to use water to extinguish fires without cutting off the power supply, in order to prevent electric shock or electrical explosion from injuring people.

Close doors and windows: If the fire begins to spread, quickly close doors and windows near the fire area to slow down the spread of fire and smoke.

Call the police and evacuate: Immediately dial the fire alarm number 119 to report the incident and notify other personnel to evacuate to avoid casualties.

Do not handle it without authorization: In situations where the fire is large or uncontrollable, do not handle it without authorization and wait for firefighters to arrive for professional rescue.

Through the above measures, the spread of fire after the electric meter box catches fire can be effectively controlled, reducing the losses and hazards caused by the fire.
