The toxicity of organic solvents is manifested in the local anesthesia stimulation caused by the solvents in contact with the human body or absorbed by the human body or the dysfunction of the entire body. All volatile organic solvents are always toxic when their vapors come into contact with the human body at high concentrations for a long time, such as: primary alcohols (except methanol), ethers, aldehydes, ketones, some esters, benzyl alcohol solvents Easily damage the nervous system; methyl carboxylate and formate can cause lung poisoning; benzene and its derivatives, ethylene glycol, etc. can cause blood poisoning; halogenated hydrocarbons can cause liver and metabolism poisoning; tetrachloroethane And ethylene glycol can cause severe kidney poisoning. Therefore, the following items should be paid attention to when using:
1. Try not to directly contact the skin with organic solvents, be sure to take personal protection
2. Pay attention to keep the experimental place ventilated.
3. If toxic organic solvents are spilled during use, all fire sources should be removed according to the amount of spillage, and the on-site personnel in the laboratory should be reminded to spray with fire extinguishers, then clean, bag and seal with absorbents, and treat them as waste solvents.
