Hazard Overview

Health hazards: Acute poisoning is mainly manifested as an anesthetic effect on the central nervous system, resulting in fatigue, nausea, headache, dizziness, and irritability. Severe cases may experience vomiting, shortness of breath, spasms, and even coma. Irritating to the eyes, nose, and throat. After oral administration, there is a burning sensation in the lips and throat, followed by dry mouth, vomiting, coma, acidosis, and ketosis. Chronic effects: Long term exposure to this product may cause dizziness, burning sensation, pharyngitis, bronchitis, fatigue, and irritability. Long term repeated contact with the skin can cause dermatitis

Explosive hazard: This product is extremely flammable and irritating

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. Seek medical attention

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

Fire protection measures

Dangerous characteristics: Its vapor and air can form explosive mixtures, which are highly flammable and explosive when exposed to open flames and high heat. Can react strongly with oxidants. 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. If exposed to high heat, the pressure inside the container increases, posing a risk of cracking and explosion

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. If the container in the fire has changed color or produced sound from the safety relief device, it must be evacuated immediately. Extinguishing agent: insoluble foam, carbon dioxide, dry powder, sand. Extinguishing fire with water 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 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

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 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, reducing agents, and alkalis. 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 26 ℃. Keep the container sealed. It should be stored separately from oxidants, reducing agents, and alkalis, 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): 400 Former Soviet Union MAC (mg/m3): 200

Engineering control: The production process is sealed and fully ventilated

Respiratory protection: When the concentration in the air exceeds the standard, wear a filtered gas mask (half face mask).

Eye protection: Generally no special protection is required, safety goggles can be worn when exposed to high concentrations

Body protection: Wear anti-static work clothes Hand protection: Wear rubber oil resistant gloves

Other protections: Smoking is strictly prohibited at the work site. Pay attention to personal hygiene and cleanliness. Avoid long-term repeated exposure

Transportation information

Packaging method: Small opening steel drum; Ordinary wooden box outside the ampoule bottle; Screw mouth glass bottle, iron cap pressed mouth glass bottle, plastic bottle or metal barrel (can), ordinary wooden box outside

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, reducing agents, alkalis, 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
