  • Stay away from electrical boxes during an earthquake

    Stay away from electrical boxes during an earthquake

    Stay away from broken electrical wires, and turn off the main fuse box or circuit breaker. last modified: 25 April, 2022Most earthquake-related injuries and deaths are caused by falling or flying objects (such as TVs, lamps, glass, or bookcases), or by being knocked to the ground. If you are in a high-rise building, stay in the building. DO NOT use. The primary dangers to workers result from: being struck by structural components or furnishings, inadequately secured stored materials, burns resulting from building fires resulting from gas leaks or electrical shorts, or exposure to chemicals released from stored or process chemicals. They may create a spark that could ignite leaking gas and cause an explosion and fire DO NOT use your telephone, EXCEPT for a medical or fire emergency. “Drop, Cover, and Hold On” is the only scientifically. During an earthquake, you should Drop, Cover, and Hold On to protect yourself from falling debris. Here is how to practice: DROP where you are onto your hands and knees.
