1. Emergency response to leakage

Evacuate personnel in the leaked contaminated area to a safe area, prohibit irrelevant personnel from entering the contaminated area, and cut off the source of fire. It is recommended that emergency responders wear positive pressure self-contained breathing apparatus and chemical protective clothing (complete isolation) recommended by the manufacturer. Do not come into direct contact with the leakage, and plug the leakage when it is safe to do so. Water mist will reduce evaporation but will not reduce the flammability of the spill in a confined space. Mix and absorb with sand or other non-flammable adsorbent, then collect and transport to waste disposal site for disposal. If there is a large amount of leakage, use dikes to contain it, and then collect, transfer, recycle or dispose of it after harmless treatment.

2. Protective measures

Respiratory system protection: Wear a gas mask when you may be exposed to its vapor. During emergency rescue or escape, positive pressure self-contained breathing apparatus should be worn.

Eye protection: Wear chemical safety glasses.

Body protection: Wear appropriate protective clothing.

Hand protection: Wear chemical-resistant gloves.

Others: Smoking, eating and drinking are prohibited at the work site. After work, shower and change clothes. Store poison-contaminated clothing separately and launder before use. Undertake pre-employment and periodic physical exams.

3. First aid measures

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

Eye contact: Lift eyelids immediately and rinse with running water.

Inhalation: Leave the scene quickly to fresh air. Keep warm and keep your respiratory tract open. Provide artificial respiration if necessary. Seek medical attention.

Ingestion: If swallowed by mistake, drink plenty of warm water, induce vomiting, and seek medical attention.

Fire-fighting methods: mist water, foam, carbon dioxide, sand.
