Skin contact: Take off contaminated clothing and rinse with plenty of running water.

Eye contact: Lift the eyelid immediately and rinse thoroughly with plenty of running water or normal saline for at least 15 minutes. Seek medical attention.

Inhalation: quickly leave the scene to a place with fresh air. Keep the airway unobstructed. If breathing is difficult, give oxygen. If breathing stops, give artificial respiration immediately. Seek medical attention.

Ingestion: Rinse mouth with water, drink milk or egg white. Seek medical attention.

Respiratory system protection: When the concentration in the air exceeds the standard, you must wear a self-priming filter gas mask (half mask). During emergency rescue or evacuation, air respirators should be worn.

Eye protection: wear chemical safety glasses.

Body protection: wear protective overalls.

Hand protection: Wear rubber and oil-resistant gloves.

Other protection: smoking, eating and drinking are prohibited at the work site. After the work is finished, clean it thoroughly. Store clothes contaminated by poisons separately and wash them for later use. Maintain good hygiene.

Leakage emergency treatment: quickly evacuate personnel from the leaked contaminated area to a safe area, and isolate them, strictly restrict access. Cut off the fire source. It is recommended that emergency response personnel wear self-contained positive pressure respirators and anti-virus suits. Cut off the leak source as much as possible. Prevent entry into restricted spaces such as sewers and flood drains. Small leakage: absorb with sand, vermiculite or other inert materials. A large number of leaks: construct a dike or dig a pit for storage. Use a pump to transfer to a tanker or a special collector for recycling or transport to a waste disposal site for disposal.

Hazardous combustion products: carbon monoxide, carbon dioxide, nitrogen oxides, hydrogen cyanide.

Fire fighting method: Firefighters must wear gas masks and full-body fire fighting clothes, and put out the fire in the upwind direction. Spray water to keep the fire container cool until the end of the fire extinguishing. If the container in the fire scene has changed color or produces sound from the safety relief device, it must be evacuated immediately. Extinguishing agent: dry powder, carbon dioxide, sandy soil. It is forbidden to extinguish fires with water, foam and acid-base fire extinguishing agents.
