Hazard Overview

Health hazards: This product is a central nervous system inhibitor. Firstly, it triggers excitement, followed by inhibition. Acute poisoning: Acute poisoning often occurs orally. It can generally be divided into four stages: excitement, hypnosis, anesthesia, and suffocation. The patient enters the third or fourth stage and experiences loss of consciousness, dilated pupils, irregular breathing, shock, circulatory failure, and respiratory arrest. Chronic effects: Long term exposure to high concentrations of this product during production can cause nasal, eye, and mucosal irritation symptoms, as well as headaches, dizziness, fatigue, irritability, tremors, nausea, etc. Long term alcoholism can cause multiple neuropathy, chronic gastritis, fatty liver, cirrhosis, myocardial damage, and organic psychosis. Long term skin contact can cause dryness, flaking, cracking, and dermatitis.

Explosive hazard: This product is flammable and irritating

Emergency measures

Skin contact: Remove contaminated clothing and rinse with running water.

Eye contact: Lift the eyelids and rinse with flowing water or saline solution. Seek medical attention.

Inhalation: Quickly leave the scene and move to a place with fresh air. Seek medical attention.

Ingestion: Drink plenty of warm water and induce vomiting. Seek medical attention.

Fire protection measures

Hazardous characteristics: Flammable, its vapor can form explosive mixtures with air, and can cause combustion and explosion when exposed to open flames or high heat energy. Chemical reactions or combustion may occur when in contact with oxidants. In a fire scene, heated containers pose a risk of explosion. Its vapor is heavier than air and can spread to a considerable distance at lower levels. It will ignite and reignite when exposed to a source of fire.

Harmful combustion products: carbon monoxide, carbon dioxide

Fire extinguishing method: Move the container from the fire scene to an open area as much as possible. Spray water to keep the fire container cool until the fire is extinguished. Extinguishing agent: insoluble foam, dry powder, carbon dioxide, sand.

Emergency response to leakage

Quickly evacuate personnel from the contaminated area to a safe zone, isolate them, and strictly restrict their entry and exit. Cut off the fire source. It is recommended that emergency personnel wear self-contained positive pressure respirators and anti-static work clothes. Cut off the leakage source as much as possible. Prevent the flow into restricted spaces such as sewers and drainage ditches. Minor leakage: Absorb or absorb with sand or other non combustible materials. You can also rinse with a large amount of water, dilute the washing water, and put it into the wastewater system. Massive leakage: Construct embankments or dig pits to contain it. Cover with foam to reduce steam disaster. Transfer to a tanker or dedicated collector using an explosion-proof pump, and recycle or transport to a waste disposal site for disposal.

Operation, processing, and storage

Precautions for operation: Closed operation, comprehensive ventilation. Operators must undergo specialized training and strictly adhere to operating procedures. It is recommended that operators wear filter type gas masks (half face masks) and anti-static work clothes. Keep away from sources of fire and heat, and smoking is strictly prohibited in the workplace. Use explosion-proof ventilation systems and equipment. Prevent steam leakage into the workplace air. Avoid contact with oxidants, acids, alkali metals, and amines. During filling, the flow rate should be controlled and there should be a grounding device to prevent static electricity accumulation. Equip with corresponding types and quantities of fire-fighting equipment and emergency response equipment for leaks. Empty containers may contain residual harmful substances.

Storage precautions: Store in a cool and ventilated warehouse. Stay away from sources of fire and heat. The storage temperature should not exceed 30 ℃. Keep the container sealed. It should be stored separately from oxidants, acids, alkali metals, amines, etc., and avoid mixing storage. Adopt explosion-proof lighting and ventilation facilities. Prohibit the use of mechanical equipment and tools that are prone to generating sparks. The storage area should be equipped with emergency response equipment for leaks and suitable containment materials.

Packaging and transportation technical requirements

Packaging method: Small opening steel drum; Small opening aluminum bucket; Ordinary wooden box outside the ampoule bottle; Screw mouth glass bottles, iron cap pressed mouth glass bottles, plastic bottles, or ordinary wooden boxes outside metal drums (cans).

Transportation precautions: The railway transportation of this product is limited to the use of self provided tank trucks by steel enterprises, and approval from relevant departments is required before shipment. Transport vehicles should be equipped with corresponding types and quantities of fire-fighting equipment and emergency response equipment for leaks during transportation. It is best to transport in the morning and evening during summer. The tank truck used for transportation should have a grounding chain, and a perforated partition can be installed inside the tank to reduce static electricity generated by vibration. It is strictly prohibited to mix and transport with oxidants, acids, alkali metals, amines, edible chemicals, etc. During transportation, it should be protected from direct sunlight, rain, and high temperatures. When stopping midway, one should stay away from sources of fire, heat, and high temperature areas. The exhaust pipe of the vehicle carrying the item must be equipped with a flame retardant device, and the use of mechanical equipment and tools that are prone to generating sparks for loading and unloading is prohibited. When transporting by road, follow the prescribed route and do not stay in residential or densely populated areas. It is prohibited to slip during railway transportation. It is strictly prohibited to use wooden boats or cement boats for bulk transportation.
