Fire Accident

The occurrence of fire accidents is universal and can occur in almost all laboratories.

Cause: 

1. Forgetting to turn off the power, causing the device to be powered on for too long and the temperature is too high.

2. The power supply line is aging and overloaded, causing the line to heat up.

3. Inadvertent or improper storage of inflammable and explosive materials, so that the fire source is in contact with flammable substances.

4. Throw the cigarette butt and get in contact with flammable substances.

Approach:

1. When combustible liquid is burned, immediately remove all combustible materials in the fire area and turn off the ventilator to prevent expansion.

2. When alcohol and other water-soluble liquids catch fire, use water to extinguish the fire.

3. When the organic solvent such as gasoline, ether or toluene is on fire, use asbestos cloth or dry sand to extinguish. Never use water, otherwise it will increase the burning area.

4. When the metal potassium, sodium or lithium is on fire, it must not be used: water, foam fire extinguisher, carbon dioxide, carbon tetrachloride, etc., can be extinguished with dry sand and graphite powder.

5. When the electrical equipment wires are on fire, do not use water and carbon dioxide fire extinguishers (foam fire extinguishers) to avoid electric shock. The power should be turned off before using a carbon dioxide or carbon tetrachloride fire extinguisher.

6. When the clothing is on fire, do not run. Immediately cover it with asbestos cloth or thick outer cover, or quickly take off your clothes. When the fire is heavy, you should roll on the floor to extinguish the flame.

7. When the cabinet equipment is found to have odor or smoke, the power should be cut off quickly, let it cool down slowly, and the fire extinguisher should be ready for use. Never rush to open the door to avoid sudden air supply or combustion.

8. Pay attention to the protection of the scene in the event of a fire. Larger fire accidents should be reported immediately. If there is a serious injury, it should be taken to the hospital immediately.

9. Familiar with the location of fire extinguishing equipment in the laboratory and how to use the fire extinguisher.
