Safety rules when working on a lathe.


The main conditions for safe work on a commercial machine are: the value of the machine, the mode of processing materials, a careful, serious attitude to the work being performed and compliance with all the requirements of these instructions.

Dangerous places on a lathe are:

1. Toothed and stepped belt drives.

2. Machine chucks with protruding parts.

3. Item being processed.

4. Chips from workpieces.

5. Lead screw and rollers.

The turner is obliged:

1. Strictly observe production and labor discipline.

2. Improve safe work methods.

3. Seek the fastest elimination of any deficiencies that could cause accidents.

4. If an accident occurs, you should immediately contact the repair center for first aid and notify the foreman or the head of the RMC. If the victim himself is not able to come to the health center and notify the foreman about what happened, then any worker who is nearby must call the employee of the health center to provide first aid and report to the foreman or the head of the RMC.

Responsibilities of a turner to ensure safe work.

Before starting work:

1. Put on a properly functioning special gear. clothes. Do not wear clothes open or too loose with ends hanging down. Do not wear a scarf or tie to work. Sleeve cuffs must be fastened without buttons; women must tuck their hair under a scarf, net or beret.

2. Check the serviceability of all parts of the wall and instrument; cutter, chuck, control levers, transfer and starting devices, etc.” and also make sure that fences are available and in good condition.

3. If, during inspection of the machine, any parts and devices are found to be faulty, it is necessary to take measures to put them in order; if it is impossible to eliminate the faults on your own, report them to the head of the RMC or the foreman. Do not start work until any problems noticed are corrected.

4. Check the presence and serviceability of guards for the headstock gears and replacement gears of the machine.

5. Check the presence and serviceability of the fence around the rotation zone of the clamps, if it has protruding parts that can catch clothing.

It is especially important to use iodine tincture in this manner on contaminated wounds.

5.4.3. First aid for fractures, dislocations, impacts.

In case of fractures and dislocations of the limbs, it is necessary to strengthen the damaged limb with a splint, plywood plate, stick, cardboard or other similar object. The injured arm can also be suspended with a sling or scarf from the neck and bandaged to the body.

In case of a skull fracture (unconsciousness after a blow to the head, bleeding from the ears or mouth), it is necessary to apply a cold object to the head (a heating pad with ice, snow or cold water) or make a cold lotion.

If a spinal fracture is suspected, it is necessary to place the victim on a board without lifting him, turn the victim on his stomach face down, while making sure that the torso does not bend, in order to avoid damage to the spinal cord.

If the ribs are fractured, a sign of which is pain when breathing, coughing, sneezing, or moving, it is necessary to tightly bandage the chest or tie them with a towel while exhaling.

5.4.4. First aid for thermal burns.

In case of burns from fire, steam, or hot objects, under no circumstances should you open the resulting blisters or bandage the burns.

For first-degree burns (redness), the burned area is treated with cotton wool moistened with ethyl alcohol.

For second-degree burns (bladder), the burned area is treated with alcohol or a 3% manganese solution.

For third-degree burns (destruction of skin tissue), cover the wound with a sterile bandage and call a doctor.

5.4.5. First aid for bleeding.

In order to stop bleeding, you must:

5.4.5.1. Raise the injured limb upward.

5.4.5.2. Cover the wound with dressing material (from a bag) folded into a ball, press it on top without touching the wound itself, and hold for 4-5 minutes. If the bleeding has stopped, without removing the applied material, place another pad from another bag or a piece of cotton wool on top of it and bandage the wounded area (with some pressure).

5.4.5.3. In case of severe bleeding that cannot be stopped with a bandage, compression of the blood vessels that supply the wounded area is used by bending the limb at the joints, as well as with fingers, a tourniquet or a clamp. In case of severe bleeding, you should urgently call a doctor.

5.5. If a fire occurs, it is necessary to call the fire department and begin to extinguish it using the available fire extinguishing equipment.

5.6. In all cases, it is necessary to follow the instructions of the head of the work to eliminate the consequences of the accident.
