Seek medical attention. Eye contact: Rinse thoroughly with plenty of water for at least 15 minutes. Seek medical attention. Inhalation: If inhaled by mistake, move the patient to fresh air. If you stop breathing, give artificial respiration immediately. Seek medical attention. Ingestion: Prohibit vomiting. Never feed anything from the mouth to an unconscious person. Rinse your mouth with water. Seek medical attention. The main symptoms and health effects of exposure to the chemical: decreased central nervous system function. Advice to rescuers: No information Special reminder from doctor: No information Timely medical care and special treatment: no data 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

The physical and chemical properties of dichloropropane

Chemical name: 1,2-Dichloropropane Harmful ingredients content CAS No. 1,2-dichloropropane ≥80.0% 78-87-5 Part III: Overview of Hazards Hazard category: Class 3.2 flammable liquid with flash point. Invasion route: skin contact, inhalation, ingestion, eye contact. Health hazards: Harmful to the body after inhalation, ingestion or absorption through the skin. 1,2-Dichloropropane has an inhibitory effect on the central nervous system; it can cause dry skin, desquamation and chapped skin; it has a stimulating effect on mucous membranes; it can cause fatty degeneration of liver, kidney and myocardium. Skin contact: Take off contaminated clothing and rinse thoroughly with soap and water. Environmental hazards: The sealing of this product has no impact on the environment. Combustion and explosion hazard: This product is flammable in case of open flame and may cause an explosion in a closed container. Part 4: First aid measures Skin contact: Take off contaminated clothing and rinse skin thoroughly with clean water. Eye contact: Lift the eyelids and rinse with running water or normal saline. Seek medical attention. Inhalation: Leave the scene quickly 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: gastric lavage. Seek medical attention. Part V: Fire Fighting Measures Hazardous characteristics: It is flammable, and its steam and air can form an explosive mixture, which can cause combustion and explosion when exposed to open flames and high heat energy. Decomposed by high heat to produce toxic corrosive fumes. It reacts with oxidants, and can easily cause combustion when exposed to open flames and high heat, and emit toxic gases. Its steam is heavier than air, and can spread to a considerable distance at a lower place, and will ignite back when it encounters a fire source. Hazardous combustion products: carbon monoxide, carbon dioxide, hydrogen chloride, phosgene. Extinguishing method: Spray water to cool the container. If possible, move the container from the fire scene to an open place. If the container in the fire scene has changed color or produces sound from the safety relief device, it must be evacuated immediately. Extinguishing agent: foam, dry powder, carbon dioxide, sand, water mist. Precautions for fire extinguishing: Water jet extinguishing is invalid. Part VI: Emergency Response to Leakage Emergency treatment: Quickly evacuate personnel from the leaked 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. Cut off the source of leakage as much as possible. Prevent entry into restricted spaces such as sewers and flood drains. Small leakage: Use sand or other non-combustible materials to absorb or absorb. It can also be washed with a large amount of water, and the washing water is diluted and put into the waste water system. A large number of leaks: build a dike or dig a pit 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. Part 7: Handling and storage Operation precautions: airtight operation, local exhaust. Operators must undergo special training and strictly abide by the operating procedures. It is recommended that operators wear filter-type gas masks (half masks), chemical safety glasses, anti-static overalls, and rubber oil-resistant gloves. Keep away from fire and heat sources, and smoking is strictly prohibited in the workplace. Use explosion-proof ventilation systems and equipment. Prevent steam from leaking into the workplace air. During filling, the flow rate should be controlled, and there should be a grounding device to prevent static electricity from accumulating. When handling, load and unload with care to prevent damage to packaging and containers. Equipped with corresponding types and quantities of fire-fighting equipment and leakage emergency treatment equipment. Empty containers may be harmful residues. Storage precautions: Store in a cool, ventilated warehouse. Keep away from fire and heat sources. The storage temperature should not exceed 30°C. Keep the container tightly closed. It should be stored separately from oxidants, acids, alkalis, and edible chemicals, and avoid mixed storage. Use explosion-proof lighting and ventilation facilities. It is forbidden to use mechanical equipment and tools that are prone to sparks. The storage area should be equipped with leakage emergency treatment equipment and suitable storage materials. Part 8: Exposure Control/Personal Protection Monitoring method: Gas chromatography Engineering control: airtight operation, local exhaust. Provide safety shower and eyewash equipment. Respiratory system protect

The truck rolls over and the dichloropropane flows everywhere, fire officers and soldiers evacuated danger on Xiangshi Road

A light truck carrying dichloropropane was involved in a car accident on the Xiangshi Expressway. The toxic liquid and gasoline leaked. The situation was very critical. After 2 hours of emergency treatment by fire officers and soldiers, the danger was successfully eliminated. Dichloropropane is a toxic, colorless liquid with a pungent odor. After being heated, it decomposes to toxic gas and even explodes. The truck was fully loaded with more than 100 plastic drums and iron drums containing dichloropropane and drove from Wuhan to Yunxi. At 9:30 that night, when it reached 9 kilometers of Xiangshi Expressway, the front wheel of the truck suddenly burst, and the body immediately rolled over, slid forward 30 meters and then lay in the middle of the highway. The plastic bucket on the car cracked to the ground, and a large amount of dichloropropane liquid flowed outward. At the same time, the vehicle's fuel tank ruptured and gasoline overflowed. After the accident, the highway patrol immediately closed the highway and asked the fire department for help. At 10 o'clock in the evening, the Xiangfan City Fire Detachment quickly mobilized three squadrons of Special Service, Xiangcheng, and Xiangyang to the scene. 11 o'clock, after dilution and washing with water, the danger on site was relieved.
