Construction sites typically need a lot of electrical installations. Lifting equipment mostly involves electricity and weights. When working with such equipment, heavy machine operators need to ensure there is no wear and tear in the machine and be sure to follow the listed safety precautions. If you do not know them, seek help from a site supervisor or a coworker who has experience using the equipment. If you are using plugged-in portable devices, such as grinders or drills, you should always check that the cables are protected, the metal casing is grounded and the power supply is supplied with an earth leakage circuit breaker. Never allow the electrical tools anywhere near water. Never stand or work directly below a heavy suspended load and always be sure to not exceed the permissible levels of load. You’ll need proper training before operating some equipment, especially a material hoist and crane.
