Use household electrical appliances safely

The danger of electric current is different from the different types of hazards at work because people cannot recognize it before it happens, while the sound of an approaching vehicle can be heard. foresee the risk of an object being dropped or smelled for a leak.

About one in every 30 electrical accidents is fatal. The majority of these accidents are electric shocks or burns. Fires and explosions when welding in flammable air, radiation caused by arc or microwave heat processing are also likely to cause injury.

Shockwave:

The danger of an electric shock is directly related to the strength and the time it flows through the body. When the amperage is small, the effect of the current is only unpleasant stimuli on the body, although it is enough to cause workers to lose their balance and fall from a ladder or scaffolding to the ground. With a medium intensity line, it causes a muscle contraction reaction and the jerky person will not release the things in his hand, making the situation quickly become very dangerous. With high intensity, the current can stop the heart and almost certainly cause death.

Electric current can also cause skin burns at the point of contact. However, severe burns can also occur without direct physical contact with the electric current. The humid environment makes the danger of electric shock greatly increase.

Electric current can pass through people thanks to the voltage. Therefore reducing the voltage also reduces the severity of electric shock injury, so it is common to use a 110v voltage wherever possible.

The main causes of electric shock are:

– The ground wire is not connected to the neutral pole in the socket but connected to the positive pole. Causing the neutral wire itself to become conductive;

– Wrong terminal connection on the socket and equipment;

– Fuse cover, circuit breaker box, output on lampholder damaged or lost; Use bare conductors.

– Flexible cables are damaged by rubbing on sharp surfaces or running underground;

– Temporarily repair flexible cables with electrical tape.

Handling electric shock accidents:

Disconnect, or if not possible, separate the victim from the electrical current by using long, clean, dry, non-conductive objects such as wooden sticks or long rubber samples, or a jacket-like fabric. Stand on dry and non-conductive materials like wood when doing this. Do not touch the victim until the current has not been cut.

If you find the person has stopped breathing, give artificial respiration, then send to an emergency and call a doctor. Continue with CPR until a doctor or ambulance arrives.

Electric supplying system:

At each workplace, there may be aerial power supply systems or deep underground. Before repairing, learn to understand the electrical system diagram.

Electrical installations:

Only qualified electricians can install and solve electrical problems. All electrical equipment must be checked and maintained periodically according to the manufacturer’s instructions.

If the device is damaged, do not repair it yourself, but leave it to an electrician. Wires and cables that supply power to the device should be mounted on walls or ceilings, not run on floors that are easily damaged or damp.

Do not tie the power cord knot, which can cause a short circuit or short circuit. When operating a stationary machine, emergency stop devices must be within reach of the operator.

Before using electrical equipment:

– Checking for defective places.

– Check the fuses and sockets, never temporarily connecting machines or sockets by bare wires connected to light bulbs or contacts.

– Check whether the insulation sheaths of wires and cables are broken or worn.

– Check grounding wires in the neutral wiring system.

Hand tools and appliances:

Double or fully insulated devices are safer than other conventional devices because they are equipped with internal protective layers in case the outer metal layer becomes conductive.

If you use a handheld device, you must be carefully instructed on its use and maintenance.

Before operating a portable power tool, check to ensure that:

– The wires and plugs are not damaged.

– There are compatible fuses.

– Set the right speed for the job.

– Electric conductors must not be in the path of other workers and not in contact with water.

– At the end of the job, make sure that the moving parts of the tool have stopped completely before placing.

Things to remember:

-If an accident occurs due to electrical contact, immediate power off.

-Do not execute on existing wires or cables.

-Never carry a hand-held tool with its cable.
