Pure product is colorless or slightly yellow crystal, with mildew odor, melting point 146 ° C, boiling point 328 ° C, relative density (water = 1) 1.72, flammable, insoluble in water, slightly soluble in alcohol, benzene, chloroform, carbon disulfide. Pentachloronitrobenzene is a serious hazard to the environment, and special attention should be paid to the pollution of water bodies. Mainly used as an intermediate, and used in soil sterilization, herbicides, etc. Harm to the human body This product is toxic, and the main ways of invading the human body are inhalation, ingestion and percutaneous absorption, which mainly damage the cardiovascular system, central nervous system, liver, kidney and hematopoietic system. first-aid Immediately after skin contact with pentachloronitrobenzene, remove contaminated clothing and rinse with plenty of running water. Immediately after eye contact, lift eyelids and rinse with running water or saline. After inhalation, quickly leave the site to fresh air and keep the airway open. If breathing is difficult, give oxygen; if breathing stops, perform artificial respiration immediately. After eating, drink plenty of warm water and induce vomiting. After taking first aid measures, you need to seek medical attention. Protective measures The maximum allowable concentration (MAC) in the air of the workshop is 1 mg/m3 in China. The production process is tightly closed, providing adequate local exhaust and providing a safe shower and eyewash equipment. When the concentration of dust in the air is high, it is recommended to wear self-priming filter dust masks, chemical safety glasses, gas-type anti-virus suits, and chemical-resistant gloves. Smoking, eating and drinking are prohibited at the job site. Workers should change their work clothes in time, do not drink alcohol before and after work, and take a bath with warm water. The unit shall arrange pre-employment and regular medical examinations of employees. Fire-fighting measures Pentachloronitrobenzene is flammable when exposed to open flames and high heat. It can react with strong oxidants and react with high heat to produce toxic nitrogen oxides and chloride gases. When extinguishing the fire, move the container from the fire to the open space as much as possible. The following fire extinguishing agents can be used: misty water, foam, dry powder, carbon dioxide, sand. Operational precautions Operators must be specially trained to strictly follow the operating procedures. When operating, keep away from fire and heat sources, avoid dust, and avoid contact with oxidants, reducing agents, and alkalis. Smoking is strictly prohibited in the workplace and explosion-proof ventilation systems and equipment are used. Lightly load and unload during handling to prevent damage to packaging and containers. The operation site should be equipped with the corresponding variety and quantity of fire-fighting equipment and leakage emergency treatment equipment. Storage and transportation considerations This product should be stored in a cool, ventilated warehouse, away from fire, heat, and stored separately with oxidants, alkalis, food and food additives, avoid mixing. The storage area should be equipped with suitable materials to contain the spills, and equipped with the appropriate variety and quantity of fire-fighting equipment. Before transporting, check whether the packaging container is complete and sealed. During transportation, ensure that the container does not leak, collapse, fall or damage. It is strictly forbidden to mix with acids, oxidants, foods and food additives. It should be protected from exposure, rain and high temperature during transportation. Leakage emergency treatment When pentachloronitrobenzene leaks, isolate the leaking contaminated area, restrict access, and cut off the fire source. It is recommended that emergency personnel wear a dust mask (full face mask) and wear a protective suit. Use a clean shovel to collect the spill in a dry, clean, covered container and transfer to a safe place. |
