This depends entirely on what you are doing. You can prevent static shocks be wearing tighter clothing, and avoiding wool and nylon. You can prevent being shocked by the wall outlet by using protective outlet covers. When working with hobby electronics, there is little more necessary then caution. Once the voltage you are working with surpasses about 1000 volts or so, there is nothing you can do except keep your distance, and pass it off to someone experienced in dealing with high voltage.
The best way to prevent short circuits that lead to fires is making sure that your over current protection is sized to the wire that it is protecting. #14 wire with a 15 amp breaker, #12 wire with a 20 amp breaker, #10 wire with a 30 amp breaker and #8 wire with a 40 amp breaker. These are common size breakers found in North American households.

Electrical equipment should be tested every 6 months like your smoke detectors and your furnace . Electrical fires are the 3rd leading cause of fires in Canada, so test ,test test.
The main safety rule is to switch off at the mains before working on electrical equipment and wiring.
There are 5 classes of fires (3 common and 2 specialty). These are common combustibles, flammable liquids and gases, live electrical equipment, combustible metals, and cooking media. These fires are then each classified into 5 groups.
Water conducts electricity and is therefore contraindicated for use on energized electrical equipment, however it is much cheaper than the chemicals that can be used on energized equipment making it more economical when water is able to be used. Similarly water should not be used on grease fires as it will spread out the grease and the fire rather than smothering it. Water if pure without contaminants does not conduct . Having stated that electrical fire can hardly be contained by water since the air itself will conduct electrons by ionization. So to contain an electrical fire a the oxygen must be removed and water will not do that.

Fires involving live electrical equipment.
Class E fire is a type of fire classification used in Australia, referring to fires involving electrical equipment. These fires occur when electricity ignites flammable materials such as wires, appliances, or electrical systems. It is important to use appropriate fire extinguishing methods and avoid using water on these fires as it can further escalate the situation.
To prevent overloading in case of an electrical fault in the equipment.
a breaker or a fuses
using high quality insulation for all electrical and electrical equipment.
this helps prevent electrical fires
Under the correct atmospheric conditions, static electricity can start a fire. It is for this reason that all electrical equipment and equipment that can cause a static electrical build up is grounded.
It's important because not only will it not work properly. But can also cause damage to the equipment or the individual. Many electrical fires are caused by incorrect use/assembly of electrical equipment
Water conducts electricity and is therefore contraindicated for use on energized electrical equipment, however it is much cheaper than the chemicals that can be used on energized equipment making it more economical when water is able to be used.

There are a lot of other fires, A B C D K. for each fire there is different equipment depending on the size of the fire
