Hazard category

General chemicals

Fire-fighting measures

Move the container from the fire scene to an open place as much as possible. Keep the fire container cool by spraying water until the fire is over. If the container in the fire scene has changed color or produces sound from the safety relief device, it must be evacuated immediately. Spray the escaping liquid with water to dilute it into a non-flammable mixture, and use water spray to protect firefighters. Extinguishing agent: water, water mist, alcohol-resistant foam, dry powder, carbon dioxide, sandy soil.

Emergency treatment

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

Eye contact: immediately open the upper and lower eyelids and rinse with running water or normal saline. Seek medical attention.

Inhalation: Leave the scene to fresh air. Seek medical attention.

Ingestion: Drink enough warm water to induce vomiting. Seek medical attention.

Packaging, storage, transportation

Packed in iron drum, 200-215KG/drum; stored in a cool, ventilated warehouse. Keep away from fire and heat sources. It should be stored separately from the oxidant and avoid mixed storage and transportation. It should be equipped with corresponding types and quantities of fire-fighting equipment. The storage area should be equipped with leakage emergency treatment equipment and suitable storage materials.
