If you are using an electric drill with a power cord, do not modify plugs,
and make sure that the power tools you use correctly match the power
outlet to reduce your chances on getting an electric shock. Also, adapter
plugs and earthed (grounded) power tools are a really bad combo.
Do not abuse the power cord. The cord isn't the reason you're having a bad
day - and it won't be, if you won't use it for carrying, pulling, or unplugging
the power tool, and will keep it away from heat, oil, sharp edges, and moving
parts.
If the power supply is interrupted
(for example, in case of a power failure or
when the mains plug is pulled), immediately set your power tool to its ‘off’
position to prevent uncontrolled restarting.
Find out if there are any utility lines hidden in the work area. Use suitable
detectors or call the local utility company for assistance. It's totally worth it -
only imagine the level of booms and ouchies that coming in contact with
electric lines, damaging a gas line, or penetrating a water line can bring.
When working outside, use an extension cord meant specifically for
outdoors use. It's going to be much more convenient, and will reduce the
risk of an electric shock.
Do not expose your power tools to rain, moisture or wet conditions. Search
“water and electricity don't mix” on YouTube, and you'll see why.
If damp conditions are unavoidable
, use a residual current device (RCD)
protected supply.
