Basic<unk>  safety The following are some examples of unsafe practices which could lead to electric injury (this list is not exhaustive.): * Using<unk>  appliances while wet (showering, bathing, etc.) as plumbing is often connected to<unk>  ground, and wet skin loses much of its resistance. Exception for newer quality appliances intended for the bathroom when not simultaneously showering, bathing, being in a path of water going to plumbing, or touching bare concrete or sheet metal. Standing on a dry carpet or rug is ideal. * All power mains outlets should have a wall cover to avoid accidentally touching the electrified sides between the wall and outlet. This is especially important for children, as their small fingers can easily reach into this gap along the sides. * Using AC<unk>  appliances around bathtubs, swimming pools, hot tubs, etc. with the risk that the appliance may fall into the water and cause electrocution. Only battery-operated devices are safe. UK Type G plug (BS 1363) * Failure to use child safety plugs in all outlets, and keeping children away from<unk>  cords. * Adjusting prongs of an<unk>  cord that are too wide or narrow them with your fingertips while simultaneously plugging the cord into the power mains. The power plug used in the UK and some Commonwealth countries provides limited protection (Type G, with the lower half of the live prongs insulated), but all others do not. * Not following manufacturer safety instructions for<unk>  appliances. This includes not using and immediately unplugging any appliance with a damaged<unk>  cord. If this cannot be done safely (i.e. damage is too close to the plug), the circuit breaker should be turned off beforehand. * Touching metallic areas of an AC<unk>  appliance while also simultaneously touching faucets, water pipes, another metallic AC appliance, or being even partly immersed in water (including wet feet). This could ground the body through metal or water, with the risk that a faulty appliance is<unk> ly "hot" on its outside cover or chassis. * Not installing Ground Fault Circuit Interrupter (GFCI) outlets or circuit breakers in all areas with plumbing, bare concrete flooring, exposed to the elements, or outdoors by a qualified electrician. (Many newer homes already have these devices pre-installed.) Running an extension cord from non-GFCI areas such as bedrooms and hallways defeats this safety feature. Oral<unk> s (above) cannot be prevented by GFCI. * At poolside, not having a non-metallic fiberglass pole or net on hand to pull someone to safety in case the pool water is electrified, and the victim is still conscious. Furthermore, to not know where the circuit breakers for the pool are located. * Failure to install a "feed-through" type GFCI to all<unk>  devices that are an integral part of a Swimming pool, or not testing it weekly. This is a particular concern due to the use of<unk> ights and pumps where persons are immersed in water. The GFCI has the typical "test" and "reset" buttons, but no plug-in outlets. A 12-volt system is safer, though not foolproof, as it is ultimately connected to the 120/240 volt power mains. Most electrocutions come from incorrectly grounded or bonded lights. This can send electric current through a pool light even if it is not turned on. * Using an ordinary vacuum cleaner in wet or damp areas. Only a "wet vac" is suitable for this purpose. Overfilling its collection container is also unsafe. * Not double checking polarity before doing a jump start, or attempting a jump on a frozen battery. Although 12-volt batteries used in vehicles are at a safe voltage, a short circuit can still cause various types of<unk> s and an explosion. * Failure to replace high-risk appliances of decades past with new ones (hand-held corded electric drills, blow dryers, etc.) * Not inquiring about the voltage when traveling abroad for those residing in the Americas, Japan, and Taiwan (countries with 110-125 volts). This includes inter-American travel, as a few countries commonly use 220-240 volts. A matching<unk>  socket (power mains) does not necessarily mean the voltage is the same as one's home country. The doubling of voltage results in a very dangerous four-fold increase in power and heat. Not checking that dual-voltage small appliances have been adjusted correctly for 220-240 volts is also unsafe. * Going near or under a downed power line, even if there's no direct contact with the wire. Also, not remaining inside your vehicle and waiting for rescue should a power line fall on it. * See also Lightning safety
