Precautions while using Electrical Equipment
Use other forms of power
Electrical risks can sometimes be eliminated by using air, hydraulic or hand powered tools. These are especially useful in harsh conditions, but remember they could introduce other hazards. If equipment has ventilation holes then make sure air circulation through these is not blocked. If equipment has a heat sink (such as the ridges on some electric motors and electronic motor drives) then make sure air can circulate freely around the heat sink. Devices with heat sinks will get hot in normal operation. Be careful where you mount these devices. Anything rubbing against these may get scorched over time.
