Safety during electrical work

Safety during electrical work must always be extremely responsible. When performing construction work, injuries often result from improper use of various tools and electric shock.

In construction companies, as a rule, briefing at the workplace on safe working practices. Data on the conducted briefings shall be reflected in the safety journal indicating the numbers of the instructions for which the briefing was conducted.

Unfortunately injuries do happen. And when an investigation is carried out about an injury that has occurred, the injured person very often says that he was not instructed on safety issues: “Yes, I signed it in some kind of magazine somewhere, but I don’t know why.” Therefore, it is necessary not only to instruct, but also to give all the required instructions for personal use to all workers under signature. So that at home in a relaxed atmosphere they could carefully read all the requirements for their specialty. It is not permissible to carry out work permits prior to the briefing.

Unfortunately, now you can see at the construction sites instructions on safe working methods, which were written twenty or more years ago. So these old-timers wander from construction to construction. And only the names of the directors of construction companies approving them change for them. This approach to the instructions should not be allowed. The tools and working conditions are changing, but the instructions are the same. Safety instructions are not works of literature that have not lost their relevance for centuries.

Strong leadership in the construction industry as a source of various injuries belongs to angle grinders (grinders). First of all, the eyes are affected. The fact is that cutting wheels rotate at a very high speed, and flying sparks have a high temperature and speed. A spark is not just fire. This is a piece of metal heated to hundreds of degrees and flying at tremendous speed. Such sparks, falling into the eyes, affect the cornea and can cause serious harm to health. Even ordinary window glass can be spoiled by these sparks.

Go to the forum of oculists and read what they write about grinders. After reading one such forum, I think no one wants to use a grinder without good safety glasses.

Cases of injuries to the hands and feet of a grinder are not uncommon, especially when the grinder is used for a long time and the worker has tired hands. Such injuries are more likely to occur when using powerful machines, or which do not have a soft start.

Perforators are a great danger to the eyes. When chiselling the walls, brick and concrete crumbs scatter in all directions. Once in the eyes, they can injure the eyes no worse than a grinder. If a too low perforator is used for this particular job, it can become very hot and the melted grease that can also get into the eyes will begin to spray out of the ventilation slots of the perforator. Therefore, when working with a hammer drill, safety glasses are required.

A team of electricians should always have several perforators of various capacities - for drilling holes in ceilings with a diameter of 6 or 8 millimeters for fasteners for trays, a low-power perforator is quite suitable and it is not necessary to use a perforator designed for drilling large-diameter holes in ceilings and main walls. Such a hammer can weigh 10 kilograms or more.

It is especially necessary to highlight powerful perforators. When drilling concrete walls with reinforcement, the drill may jam.In this case, of course, the protective coupling is triggered, which disengages the transmission of torque to the drill. But for powerful perforators, the response threshold of protective couplings is such that not every worker can hold a perforator and it is possible to rotate a perforator around a stuck drill. It’s good if you manage to get rid of a bruise on your face.

Our common misfortune is attempts to save on ladders. Step-ladders should be periodically inspected and discarded stiffeners should be discarded. An electrician can often work all day with a stepladder, and his health depends on its quality and reliability. It is unacceptable to use ladders with broken steps and falling to the side due to loss of stiffness. The height of the ladder is also important. The installer must not stand up on his toes or place objects under his feet.

Very often, electricians themselves weld the ground loop, not having enough experience in welding work and workwear required for such work. Hence the injury - first of all, the eyes suffer again. Not being able to choose the right protective glass in the mask, they get a burn of the cornea of ​​the eyes.

Electric shock mainly occur when voltage is applied to part of the wiring. And electricians at this time install sockets and connect lamps. In this case, the voltage may suddenly appear on bare wires. It does not even help to check the absence of voltage on the cable. Five minutes ago he was gone, and suddenly appeared. First of all, the task of the foreman of electricians should be strict control over the supply of voltage and monitoring the entire circuit. This happens more often at large construction sites.

Also, great care must be taken when dismantling old wiring. There are frequent cases when the voltage from the old mains is completely removed. But part of the cables through the construction site passes in transit, and they may be energized. This happens even in residential buildings, when the cable to the neighboring apartment passes along the wall of another apartment.

It is impossible in one article to describe all the troubles that may lie in wait for installers at a construction site. Much depends on the qualifications of foremen and safety engineers, on their ability to properly train subordinates in safe working methods.
