Work Protection With Angle Grinder

Safety precautions when working with an angle grinder (angle grinder)

Using an angle grinder, it is necessary to observe a number of rules that will ensure the safety of working with this tool:

Do not use an angle grinder without a guard. The cover must be between the disc and the operator. This is necessary in the event of the destruction of the disk, in order to protect a person who works with an angle grinder from splinters of the disk.

It is necessary to use discs that correspond to the “angle grinder” type in all respects: outer diameter, thickness, landing diameter, and also at the maximum speed.

Before starting work, be sure to check the integrity of the abrasive disc. it should not have even the slightest cracks and chips. A circle that has been damaged (albeit invisible at first glance) as a result of a fall or impact cannot be used. This can lead to destruction of the disc during operation and personal injury.

It is forbidden to use discs from a circular saw with an angle grinder.

The workpiece you are working with must be firmly fixed to the work surface. Hold the tool with both hands.

During metal cutting, very often there are cases when the wheel becomes jammed, the angle grinder at this moment can very strongly reject the workpiece or slip out of hands. All this happens in a split second, so the master must be prepared for such a situation and hold the car very firmly. This is very common among small angle grinders: work occurs at high speeds with a relatively small mass of the tool.

Be sure to wear safety glasses and a respirator before work. If this rule is not observed, sparks, abrasive dust, or even a fragment of the disk may get into the eyes, which, again, will lead to serious injuries. Use ear muffs.

Wear protective clothing over the entire body. During metal cutting, the cutting temperature is very high. If even one particle gets on the body, it can cause a burn. It is best to use cotton clothes.

Keep the angle grinder at the same angle during operation.

Work Protection With Angle Grinder

Use the tool for its intended purpose.

Do not use the tool for the work for which it was not designed in the required power range (for heavy work, you need a tool designed for hard working conditions; for carrying out light work, a low-power tool is enough). Do not use the tool for purposes for which it was not intended.

It is important to observe the simplest rule: have completed the cut. turn off the tool. It can be put on the table only after the disk has completely stopped.

Work zone

Keep your work area clean and well lit. Clutter, trash, unlit areas of the workplace can lead to an accident. When working with a power tool, do not allow unauthorized persons and children close to your workplace. The entire tool should be kept out of the reach of unauthorized persons, it is preferable to store them in a tool cabinet or room for a time when these tools are not used.

Remove service (installation), mounting tools (wrenches, screwdrivers, etc.) before turning on the equipment. A tool or keys located in the working area of ​​the equipment may get into moving parts of the tool, which may result in injury to the operator.

Eye protection: a mandatory requirement is to wear special goggles, masks (ordinary glasses are not enough to protect the eyes).

Hearing protection: hearing protection is recommended during periods of prolonged use.

Shoes: in cases where there is a risk of damage to the legs with heavy objects or the risk of slipping on wet or slippery floors, appropriate non-slip safety shoes should be worn.

Head protection: in cases where there is a risk of falling objects or hitting protruding or low-lying obstacles, a hard construction helmet should be worn.

Respiratory protection: in cases where the machining operation leads to the formation of dust, use protective masks or special dressings. Use a respirator when special respiratory protection is required during work.

Avoid unintentional starting.

For equipment powered by a power supply: Before plugging the instrument into a power outlet, make sure that the switch (s) are in the OFF position.

For battery equipment: Before connecting the battery to the tool, make sure that the switch (s) are in the OFF position.

When transporting equipment, make sure that the switch is always in the off state.

Dust removal equipment

If the power tool is equipped with a dust removal and collection device, make sure that it is connected properly and in good working order. The use of a vacuum cleaner can reduce the dangers posed by spent dust and chips.

Disconnect power tools

When shutting down, ensure that the power tool is disconnected from the power supply. Disconnect the power tool from the power supply also before servicing, lubricating or making adjustments and when replacing accessories such as blades, drills, cutters, etc.

electrical safety
