Everyday electrical safety

Be especially careful in the bathroom, basement, kitchen, balcony and outdoors, because these places have conditions that increase electrical hazards:


• conductive flooring (concrete, bricks, ceramic tiles);
• metal structures and metal utility pipelines (hot and cold water, gas and central heating metal pipes, radiators, baths, metal parts of the shower booth, gas and electric stoves).


Lightning protection. It is possible to securely protect your home against overvoltage created by lightning by using internal and external lightning protection systems. The external lightning protection ensures safe conduction of the lightning current to the ground, while the internal protection system consists of potential equalization and overvoltage protection systems indoors.


It is prohibited:
• to operate electric appliances if: even seemingly insignificant damage is visible, the body is damaged, the wire insulation is damaged, the plug is damaged or absent;
• to use self-made or repaired fuse links;
• to repair electrical devices connected to the power network;
• to replace bulbs and clean lamps without disconnecting power;
• to hammer nails or drill holes in walls and ceilings without checking for electrical wiring;
• to use home appliances connected to the power network in the yard or garden: washing machines, clothes irons, juicers, electric kettles, and other electrical devices not intended for usage outdoors.


When purchasing a new electric appliance:
• at particularly hazardous places, use a residual current device for the protection of people, pets and property;
• for installation use multi-wire cables with copper strands. For single-phase electrical devices – three-wire cables, for three-phase electrical devices – five-wire cables and a grounded plug;
• it is recommended to select devices with double insulation, as that will provide protection against electrical trauma and make it easier to connect these devices to the power network;
• for convenient and safe operation, install switch disconnectors with suitable specifications in place of the old fuses;
• in order to ensure uninterrupted operation of office equipment, it is useful to have an uninterruptable power supply (UPS);
• if it is not possible to purchase devices with double insulation, select devices that have a body with protective grounding, which is indicated by a grounding plug.


Remember that:
• installation of the home electrical network may be performed only by specialists from licensed firms or certified electricians;
• it may be dangerous to simultaneously touch electrical devices and structures connected to the ground;
• before connecting a new electrical device to the power network, it is necessary to carefully become acquainted with its operating instructions;
• when working outside, in the garage, basement or shed, you must use only special lamps designed for a 12 V connection;
• to prevent potential accidents, qualified maintenance and periodical inspections of electrical installations must be performed. It is conducted by certified specialists.
