Avoid release to the environment.

Incident response: If the skin (hair) is contaminated: immediately remove all contaminated clothing. Wash skin/shower with water. In case of fire: Use water spray, alcohol-resistant foam, dry powder or carbon dioxide to extinguish the fire. If swallowed: call a detoxification center or doctor immediately. gargle. If inhaled by mistake: Move the victim to a place with fresh air and keep a resting posture that is comfortable for breathing. If you feel unwell, call a detoxification center/doctor.

Part 5 Fire Fighting Measures

Extinguishing method and extinguishing agent: Use water spray, alcohol-resistant foam, dry powder or carbon dioxide to extinguish the fire.

Special hazards: liquid and vapor are flammable. Exposure to heat or open flames will cause a moderate fire hazard. Vapor and air can form an explosive mixture. Exposure to heat or open flame will have a moderate explosive hazard. The vapor can diffuse for a long distance and reach the ignition source. Heat can cause expansion or decomposition, causing the container to rupture sharply. It can produce toxic carbon monoxide (CO) gas when burned.

Special fire extinguishing method: No information

Protective equipment for firefighters: If necessary, wear self-contained breathing apparatus to fight the fire. Use water spray to cool unopened containers.

Part VI Emergency Response to Leakage

Operator protective measures, protective equipment and emergency procedures: wear breathing masks. Prevent inhalation of steam, mist or gas. Ensure adequate ventilation. Remove all sources of ignition. Evacuate personnel to a safe area. Prevent the accumulation of steam to an explosive concentration, which can accumulate in low-lying places.

Environmental protection measures: Taking measures to prevent further leakage or overflow under the conditions of ensuring safety. Do not let the product enter the sewer. Prevent discharge into the surrounding environment.

The containment and removal methods of the leaked chemicals and the disposal materials used: use an electric anti-electric vacuum cleaner or a wet brush to collect the spillage and place it in a container, and dispose of it according to local regulations.

Preventive measures to prevent secondary hazards: Under safe conditions, take measures to prevent further leakage or overflow. Do not let the product enter the sewer. Prevent discharge into the surrounding environment.

Part Seven: Handling and Storage

Operational disposal: Avoid contact with skin and eyes. Prevent inhalation of steam and smoke. Keep away from fire sources. No smoking. Take measures to prevent static electricity generation.

Storage: Store in a cool place. Keep the container tightly closed and store in a dry and ventilated place. Containers that have been opened must be carefully resealed and kept upright to prevent leakage. Suggested storage temperature: 2-8°C.

Part 8. Exposure control and personal protection
