Whenever a project involves exposure to electrical equipment or electricity, check and double-check that the power is off before beginning your work. Again, there should be a main electric panel for the entire facility. Find this panel and flip the switch to off. Rubber soled shoes and non-conductive gloves provide a barrier. Putting a rubber mat on the floor is another effective precaution. Rubber does not conduct electricity and will help you avoid getting shocked. Make sure that all of your tools have a three-pronged plug, and inspect all equipment for signs of damage. It is also important to turn off power tools before connecting them to electricity. Always keep power tools away from water, and clear the work area of flammable gasses, vapors, and solvents when tools are in use. It is always wise to have a second person around to assist you when working with electricity. This second person can double check to ensure you have followed all necessary precautions. Also, if something does go wrong and you do get shocked, this second person can immediately get you the help you need.  Make sure you communicate well with this other person. Many electrical accidents occur because of miscommunication. You need to be able to trust that when this person says the power is off, it is actually off.  Even if you trust this other person with your life, it is probably a good idea to double check and make sure the power is off for yourself. Never assume anything when dealing with electricity. Working with electricity is inherently dangerous and complicated. If you are not completely confident in your skills, bring in a trusted electrician to complete the job.
