        Notes
        Environmental impact
        1. Health hazards
        Invasion route: inhalation, ingestion, transdermal absorption.
        2. Toxicological information and environmental behavior
        Hazardous characteristics
        Flammable, its vapor and air can form an explosive mixture. Exposure to open flames and high heat can cause combustion and explosion. It can react with oxidants. Its vapor is heavier than air and can spread to a considerable distance in a lower place, and it will cause back-combustion when it encounters an open flame.
        Combustion (decomposition) products: carbon monoxide, carbon dioxide.
        Leakage emergency response
        Quickly evacuate personnel from the contaminated area to a safe area, isolate them, and strictly restrict access. Cut off the fire source. It is recommended that emergency personnel wear self-contained positive pressure breathing apparatus and fire protective clothing. Cut off the source of leakage as much as possible to prevent entry into restricted spaces such as sewers and flood drains. Small leakage: Use activated carbon or other inert materials to absorb. It can also be scrubbed with an emulsion made of a non-flammable dispersant, and the lotion is diluted and put into the waste water system. A large number of leaks: construct dikes or dig pits for storage; cover with foam to reduce steam disasters. Use explosion-proof pump to transfer to tank truck or special collector, recycle or transport to waste disposal site for disposal.
        Protection measures
        Respiratory protection: When you may be exposed to its vapor, you should wear a self-priming filter respirator (half face mask). It is recommended to wear an air respirator during emergency rescue or evacuation.
        Eye protection: wear chemical safety glasses.
        Body protection: wear anti-static overalls.
        Hand protection: Wear benzene and oil resistant gloves.
        Others: Smoking is strictly prohibited at the work site. After work, take a shower and change clothes. Pay attention to personal hygiene.
        First aid measures
        Skin contact: Take off contaminated clothing and wash skin thoroughly with soap and water.
        Eye contact: Lift the eyelid and rinse with running water or normal saline. 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: Drink enough warm water to induce vomiting. Seek medical attention.
        Fire extinguishing method: use foam, carbon dioxide, dry powder, sand to extinguish the fire. Using water to extinguish a fire is ineffective, but water can be used to keep the containers in the fire site cool [3]  .
        Safety instructions
        S16: Keep away from fire.
        S23: Do not breathe steam.
        S25: Avoid contact with eyes.
        S29: Do not pour residue into the drain.
        S33: Take protective measures to prevent static electricity from occurring.
        Hazard category code
        R11: Very flammable.
        R66: Repeated contact may cause dryness or chapped skin.
