Part Four: First Aid 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.

Part 5: 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. 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 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.

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), 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.
