Part Three: Overview of Hazards

Hazard category:

Invasion route:

Health hazards: Its vapor or mist can be irritating to the eyes, mucous membranes, and respiratory tract. The symptoms of poisoning may include burning sensation, cough, wheezing, laryngitis, shortness of breath, headache, nausea, and vomiting. This product can cause peripheral neuropathy. Strong irritant to the skin.

Environmental hazards: Harmful to the environment, can cause pollution to water bodies, soil, and atmosphere.

Explosive hazard: This product is extremely flammable and has strong irritants.

Part Four: First Aid Measures

Skin contact: Immediately remove contaminated clothing and thoroughly rinse the skin with soap and water. Seek medical attention.

Eye contact: Immediately lift the eyelids and thoroughly rinse with plenty of flowing water or saline solution for at least 15 minutes. 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: Rinse mouth with water and drink milk or egg whites. Seek medical attention.

Part 5: Fire Protection Measures

Dangerous characteristics: Its vapor and air can form explosive mixtures, which can cause combustion and explosion when exposed to open flames or high heat energy. A large amount of smoke is produced during combustion. Can react strongly with oxidants. High speed impact, flow, and agitation can cause combustion and explosion due to the generation of electrostatic spark discharge. 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.

Part 6: Emergency Response to Leakage

Emergency response: 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.

Part 7: 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), chemical 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. 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 25 ℃. 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.
