Electrical safety in case of operation of lighting devices

Lighting electric devices as consumers of an electrical energy, also bear in themselves safety.

The direct contact of the person with lamps in use is absent (except for replacement of the fused lamps) therefore a false impression is made that lighting devices don’t constitute danger to the person. But in case of not observance of simple rules of electrical safety, even lighting devices can be a defeat source electric current. We will consider several rules which should be observed for safety in case of operation of lighting fixtures.

Electrical safety in case of operation of lighting devices

First of all, it should be noted that lamps and switches of lighting shall be chosen taking into account features of the environment where they will be established. If it is a bathroom, then it is necessary to choose the lamp and the switch which have a sufficient protection against moisture and water splashes. In this case operation of the lamps and switches of lighting which don’t have a sufficient protection against moisture involves danger of defeat electric current.

As for the switches of lighting which don’t have a protection against moisture, in case of accomplishment of transactions with them, hands shall be dry. Very often in the course of accomplishment the house light of works in the room is turned on by a wet hand. In case of a moisture entry on a contact part of the switch the probability of blow by electric current is high.

Separately it is necessary to consider safety rules when replacing of the fused lamps for the lamp. The basic rule is a de energizing of the lamp. As a rule, the switch of lighting breaks off the phase conductor of lighting. That is, in fact, for de energizing of the lamp it is enough to switch-off the corresponding switch of lighting. But, there is also a probability that in case of accomplishment of connection of lighting the mistake was made and on a gap in the switch there is a zero conductor, and the phase conductor approaches the lamp.

For example: the glow lamp is damaged and there will be a need of twisting of a socle which remained in the boss, the person can get under tension as the phase conductor wasn’t disconnected.

Therefore before making replacement of a lamp or to eliminate small defects of the lamp, it is necessary to make sure that tension on the lamp (on elements on which presence of tension is possible and to which the touch is possible) is absent.

If the switch of lighting doesn’t break off the phase conductor, then it is necessary to switch-off the automatic switch in a distribution guard which performs food of lines of consecrations or in case of its absence to cut off power an electrical wiring completely. The error of connection of the switch of lighting needs to be eliminated further without fail.
