Hazard Overview

Health hazards; Has a mild irritant effect on the eyes and upper respiratory tract. Continuous inhalation can cause dizziness, nausea, drowsiness, and other anesthesia symptoms. Liquid contamination of the skin can cause itching.

Explosive hazard: This product is extremely flammable.

Emergency measures

Skin contact: Remove contaminated clothing and thoroughly rinse the skin with soap and 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. Keep the respiratory tract unobstructed. If breathing is difficult, administer oxygen. If breathing stops, immediately perform artificial respiration. Medical ingestion: Drink sufficient warm water and induce vomiting. Seek medical attention.

Fire protection measures

Hazardous characteristics: Extremely flammable, its vapor can form explosive mixtures with air, and it is highly flammable and explosive when exposed to open flames and high heat. Contact with oxidants can cause strong reactions and even lead to combustion. 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: Spray water to cool the container, and if possible, move the container from the fire scene to an open area. If the container in the fire has changed color or produced sound from the safety relief device, it must be evacuated immediately. Extinguishing agent: foam, carbon dioxide, dry powder, sand. Using water to extinguish the fire is ineffective.

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 with activated carbon or other inert materials. It can also be brushed with lotion made of incombustible dispersant, and the washing solution is diluted and discharged 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.

Handling 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 self-priming filter type gas masks (half face masks), safety goggles, anti-static work clothes, and rubber oil resistant gloves. 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. During filling, the flow rate should be controlled and there should be a grounding device to prevent static electricity accumulation. Handle with care during transportation to prevent damage to packaging and containers. 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 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

Contact control and individual protection

China MAC (mg/m3): 100 Former Soviet MAC (mg/m3): 80

Engineering control: The production process is sealed and fully ventilated. Provide safety shower and eye wash equipment.

Respiratory protection: Generally, no special protection is required. When exposed to high concentrations, a self-priming filtering gas mask (half mask) can be worn. Body protection: Wear anti-static work clothes. Eye protection: Wear safety goggles when the concentration in the air exceeds the standard. Hand protection: Wear rubber oil resistant gloves

Other protections: Smoking is strictly prohibited at the work site. Avoid long-term repeated exposure.

Transportation information

Packaging method: Small opening steel drum; 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: During transportation, the transport vehicle should be equipped with corresponding types and quantities of fire-fighting equipment and emergency response equipment for leaks. 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 and other substances. 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.
