| Environmental Impact | (1) Health hazards Invasion routes: inhalation, ingestion, percutaneous absorption. Health hazards: Inhalation, oral or transdermal absorption may pose a risk to the body. Has irritant properties. (2) Toxicological data and environmental behavior Acute toxicity: LD504600 mg/kg (orally administered to rats); 2582mg/kg (rabbit oral); 500mg/kg orally, minimum lethal dose. Hazardous characteristics: Its vapor can form an explosive mixture with air. Exposure to open flames, high heat, and strong oxidizing agents can easily cause combustion. Contact with oxidants can cause violent reactions. Contact with air or under light conditions can generate peroxides with potential explosive hazards. Its vapor is heavier than air and can diffuse to a considerable distance at lower points. When exposed to open flames, it can ignite again. Combustion (decomposition) products: carbon monoxide, carbon dioxide. |

| Emergency response methods | (1) Leakage emergency response Quickly evacuate personnel from the contaminated area to a safe area, isolate them, and strictly restrict entry and exit. Cut off the fire source. It is recommended that emergency personnel wear self-contained positive pressure respirators and fire protective clothing. Cut off the source of leakage as much as possible. Prevent entry into restricted spaces such as sewers and drainage ditches. Minor leakage: Absorb with sand, vermiculite, or other inert materials. It can also be brushed with lotion made of incombustible dispersant, and the washing solution is diluted and discharged into the wastewater system. Large amount of leakage: building embankments or digging pits for containment; Cover with foam to reduce steam disaster. Transfer to a tank truck or dedicated collector using an explosion-proof pump, recycle or transport to a waste disposal site for disposal. (2) Protective measures Respiratory protection: When the concentration in the air exceeds the standard, wear a filtered gas mask (half face mask). Eye protection: If necessary, wear chemical safety goggles. Body protection: Wear anti-static work clothes. Hand protection: Wear rubber gloves. Other: Smoking, eating, and drinking are prohibited at the workplace. After work, take a shower and change clothes. Pay attention to personal hygiene and hygiene. (3) First aid measures for skin contact: Remove contaminated clothing and thoroughly rinse the skin with soap and water. Eye contact: Lift the eyelids and rinse with flowing water or physiological saline. Seek medical attention. Inhalation: Quickly remove from the scene to a place with fresh air. Maintain airway patency. If breathing is difficult, administer oxygen. If breathing stops, immediately perform artificial respiration. Seek medical attention. Ingestion: Drink plenty of warm water, induce vomiting, and seek medical attention. Fire extinguishing method: Move the container from the fire site to an open area as much as possible. Spray water to keep the fire container cool until the fire is extinguished. If the container in the fire scene has changed color or produced sound from the safety pressure relief device, it must be evacuated immediately. Extinguishing agent: insoluble foam, dry powder, carbon dioxide, sand. Water extinguishing is ineffective. |
