On matters needing attention of acetone in jinhao chemical industry co

Hazard profile

Health hazards: acute poisoning is mainly manifested as the anesthetic effect on the central nervous system, with fatigue, nausea, headache, dizziness and irritability. Severe vomiting, shortness of breath, convulsion, even coma. Irritating to eyes, nose and throat. After oral administration, there was a burning sensation in the mouth and throat, followed by dry mouth, vomiting, coma, acidosis and ketosis.

Chronic effects: long-term contact with the product appear dizziness, burning sensation, pharyngitis, bronchitis, fatigue, easily excited. Repeated contact with the skin may cause dermatitis.

Fire and explosion hazard: this product is extremely flammable and irritating.

First aid measures

Skin contact: remove contaminated clothing and rinse thoroughly with soap and water.

Eye contact: lift eyelid and rinse with flowing water or normal saline. Go to a doctor.

Inhalation: quickly remove from site to fresh air. Keep respiratory tract open. If breathing becomes difficult, administer oxygen. If breathing stops, give artificial respiration immediately. Go to a doctor.

Ingestion: drink enough warm water to induce vomiting. Go to a doctor.

Fire control measures

Dangerous characteristic: its steam and air can form explosive mixture, easy to burn and explode in case of open fire and high heat. It reacts strongly with oxidants. Its vapors are heavier than air and can spread far and wide at a lower level, where a source of fire can ignite back. In case of high heat, the pressure inside the vessel increases, and there is a risk of cracking and explosion.

Harmful combustion products: carbon monoxide, carbon dioxide.

Fire extinguishing method: move the container from the fire site to the open place as far as possible. Spray water to keep fire containers cool until the end of the fire. All personnel must evacuate immediately if the container in the fire has discolored or is making noises from the safety relief device.

Extinguishing agent: soluble foam, carbon dioxide, dry powder, sand. Water is ineffective in extinguishing fire.

Emergency treatment of leakage

Emergency treatment: quickly evacuate the personnel from the leakage contaminated area to the safety zone, isolate them and strictly restrict their access. Cut off the fire. It is suggested that emergency personnel wear self - contained positive pressure respirator and anti - static overalls. Cut off the source of leakage as much as possible. Prevent the drain, drainage ditch and other restrictive space.

Small leakage: adsorption or absorption by sand or other non-combustible materials. It can also be washed with plenty of water, diluted and put into a waste water system.

Large leakage: build a dike or dig a pit. Cover with foam to reduce vapor hazard. Transfer to tanker or special collector with explosion-proof pump, recycle or transport to waste disposal site for disposal.

Operational considerations

Closed operation, full seal. Operators must be specially trained and strictly abide by the operating procedures. It is recommended that operators wear filter gas mask (half mask), safety glasses, antistatic overalls and rubber oil-resistant gloves. Keep away from fire and heat sources. No smoking in the workplace. Use explosion-proof ventilation systems and equipment. Prevent leakage of steam into the workplace air. Avoid contact with oxidant, reducing agent and alkali. Filling should control the flow rate, and there is an grounding device to prevent the accumulation of static electricity. Handle with care to prevent damage to packaging and containers. Equipped with the corresponding variety and quantity of fire equipment and leakage emergency treatment equipment. Empty containers may contain harmful residue.

Laws and regulations

(chemical dangerous goods safety management regulations promulgated by the state council on February 17, 1987), the chemical dangerous goods safety management regulations, implementing rules (change law is sent [1992] 677), using chemicals workplace safety regulation (no. 423 [1996] labor department is sent) such as laws and regulations, for the safe use of hazardous chemicals, production, storage, transportation, loading and unloading and so on all has made the corresponding provisions; Classification and marking of commonly used hazardous chemicals (GB 13690-92) classify the substances as category 3.1 low-flash flammable liquids.
