What Are the Medical Uses of Coal Oil?

Kerosene ^[1] (lamp kerosene; kerosene; kerosine) mainly refers to a chemical substance, which is a type of light petroleum products. It is derived from natural petroleum or artificial petroleum through fractionation or cracking. The single term "kerosene" generally refers to lighting kerosene. Also known as kerosene for lamps and lamp kerosene, also known as "fire oil", commonly known as "foreign oil" and Cantonese also called "fire water". The entry introduces the domestic history, physical and chemical properties, preparation methods, uses, toxicity, leakage treatment, and protective measures of kerosene.

Evacuate personnel from the leaked contaminated area to a safe area. Unrelated personnel are prohibited from entering the contaminated area and cut off the source of fire. It is recommended that emergency handlers wear gas masks and general fire protection suits to plug leaks while ensuring safety. Water spray reduces evaporation, but does not reduce the flammability of leaks in confined spaces. Absorb with sand or other non-combustible adsorption mixture. It is then collected and transported to a waste disposal site. It can also be burned in place if it is safe. If there is a large amount of leakage, build a dike to contain it, and then collect, transfer, recycle or harmlessly dispose of it.

Engineering control ^[5] : The production process is airtight and exhausted in an all-round way. Provide safety shower and eyewash equipment.

Respiratory protection: Wear a gas mask when exposed to high concentrations.

Eye protection: Wear chemical safety goggles when exposed to high concentrations.

Protective clothing: Wear work clothes.

Hand protection: Wear protective gloves if necessary.

Other protection: No smoking at the work site. Avoid prolonged repeated exposure.
