Signs and posters on electrical safety, auxiliary signs and plates
Posters and signs of safety serve for the danger warning of defeat as electric current, for prohibition of contacts with the switching equipment, for definition of the place of work, etc.
Posters are carried out by figurative and subdivided on warning, forbidding, ordering and indicative. Signs are carried out by constants.
The warning posters serve for the danger warning of approach to the current carrying parts which are energized. These posters carry out 280x210 mm in size.
"Cost the poster. Tension" serves as electric current for the danger warning of defeat. It is applied in electric units of power plants and substations by tension to and higher than 1000 V.V ZRU hang out it on temporary barriers of the current carrying parts which are under the operating voltage (if constant barrier is removed); on temporary barriers of passes where it is impossible to come; on constant barriers of the cameras next to the workplace. In the SHOUTING posters hang out during the works performed from the earth on the ropes and cords protecting the workplace; on designs, near the workplace on the way to the next current carrying parts which are energized.
The poster "Do not get. Will kill!" serves for the danger warning of rise on designs at which approach to the current carrying parts which are energized is possible. Hang out in RU on designs next with intended for raising of personnel to the workplace located at height.
Poster "Testing. It serves life-threatening" for the danger warning of defeat by electric current when carrying out tests by the increased tension. It is hung out the text outside on the equipment and barriers of current carrying parts by preparation of the workplace for carrying out tests by the increased tension.
The forbidding posters serve for action prohibition with switching devices at which wrong turning on tension to the place of works can be given. Posters carry out the sizes 240х130 (80x50) mm.
"Not to include the poster. People work" serves for prohibition of giving of tension on the workplace. It is used in electric units tension to also by higher than 1000 Century. The poster is hung out on drives of disconnectors, separators and switches of loading, on keys and buttons of distance control, on the switching equipment to 1000 V (automatic machines, breakers, switches) at which wrong inclusion tension on the workplace can be given. On the accessions up to 1000 V which do not have in the scheme of switching devices, the poster is hung out at the removed safety locks.
"Not to include the poster. Work on the line" serves for prohibition of giving of tension to the line at which people work. The same scope, as previous, but hang out on drives, keys and buttons of management of those switching devices at which wrong turning on tension on the air or cable line at which people work can be given.
"Not to open the poster. People work" serves for prohibition of supply of compressed air or gas. It is applied in electric units of power plants and substations. It is hung out on valves and latches: air ducts to air collectors and pneumatic drives of switches and disconnectors at which wrong opening compressed air on the working people can be given or the switch or the disconnector on which people work is put in action; hydrogen, carbon dioxide and other pipelines at which wrong opening there can be the danger to the working people.
The ordering posters serve for the instruction to the working personnel of the place prepared for work or safe access to it. These posters carry out the sizes 250x250 and 100х100 of mm.
The poster "Work Here" serves for the indication of the workplace. It is applied in electric units of power plants and substations. It is hung out in the workplace. In the SHOUTING in the presence of barriers of the workplace hang out in the place of pass for barrier.
The poster "Get Here" serves for the indication of the safe way of rise to the workplace located at height. It is hung out on designs or stationary ladders on which rise to the workplace located at height is allowed.
The indicative poster "Is grounded" points out inadmissibility of giving of tension on the grounded site of the electric unit. Its sizes 240x130 and 80x50 of mm. It is hung out in electric units of power plants and substations on the drive to disconnectors, separators and switches of loading at which wrong turning on tension on the grounded site of the electric unit and also on keys and buttons of distance control can be given by them.
Signs of safety serve as electric current for the danger warning of defeat (Carefully! Voltage!). The sign of safety becomes stronger constantly in electric units tension to and higher than 1000 V of power plants and substations, on the VL support over 1000 V (the sign with the yellow background) or on the VL steel concrete support (the sign with the background in the form of the surface of concrete). In electric units of power plants and substations the sign becomes stronger on outer side of entrance doors of RU except for doors of CREWE and KTP located in these devices; outside doors of cameras of switches and transformers; barriers of the current carrying parts located in production rooms; doors, boards and assemblies up to 1000 V.
On the VL support the sign becomes stronger (on metal and wooden) or is applied (on steel concrete) in the inhabited area at the height of 2,5 — 3 m from the earth at flights less than 100 m — through the support, and at flights more than 100 m and upon transitions through roads — on each support. Upon transitions through roads signs have to be turned towards the road, and in other cases they are located sideways support in turn from the right and left-hand side.
Posters and signs are recommended to be produced from insulants (textolite, the micarta, polystyrene, etc.). For open electric units application of posters from metal is allowed. In electric units with the large-size equipment the sizes of posters are allowed to be increased concerning 2:1, 4:1 and 6:1 to the sizes specified in the text.Top
