Electromechanical Injury Accident
Most occur in laboratories with high-speed rotation or impact motion, laboratories in live working, and some laboratories with high temperature production.
1. Improper operation or lack of protection, causing crushing, snagging and collision.
2. Violation of operating procedures or leakage of electric shock and arc sparks caused by aging of equipment and facilities.
3. Improper use of high temperature gas, liquid damage.
1. If electric furnace, electric heating sleeve, electric agitator, etc. are often used in the experiment, when using electrical appliances, the human body should be prevented from directly contacting the conductive part of the electrical appliance or the asbestos mesh wire should be in contact with the electric resistance wire of the electric furnace, and cannot be held by wet hands or hands. Wet objects are in contact with the electric plug. Do not drop water or other solvents into the electric heating sleeve to prevent short circuit.
2. In order to prevent electric shock, the metal casing of the device and equipment should be connected to the ground wire. After the experiment, the instrument switch should be turned off, and then the plug connected to the power supply should be turned down.
3. Check the electrical equipment for leakage. You should use a test pencil. Any instrument that leaks electricity cannot be used.
First Aid Method:
1. Turn off the power immediately.
2. Use a dry wooden stick to separate the wire from the electric shock.
3. First-aiders must take safety measures to prevent electric shock, and the hands or feet must be insulated. Breathing artificially if necessary and immediately sent to hospital for treatment.
