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.

Why are electrical distribution boxes dustproof

They are built to withstand harsh environmental conditions, including rain, dust, and extreme temperatures. These boxes house electrical components like circuit breakers, fuses, and outlets, providing a safe and organized way to manage power distribution for various outdoor. These components are very sensitive and are easily eroded by impurities such as dust and dirt, which will affect the normal operation of the equipment and even cause serious consequences such as fire. In addition, dust will also reduce the heat dissipation efficiency of the distribution box. However, the outdoor environment is complex and changeable, and extreme weather, sandstorms and other phenomena often occur, which requires metal distribution boxes to have good waterproof and dustproof performance to ensure the stable operation of the power system. Key design points include high-quality materials like ABS plastic, aluminum, and stainless steel that resist corrosion and UV. A waterproof distribution box protects electrical components from water, dust, and harsh weather. You benefit from several key features that make these boxes reliable for outdoor and industrial environments.
