First of all; do not be paralyzed! Do not think that this organic material toxicity is small can be negligent, because some toxic substances can accumulate over time! If you want to engage in this work for a long time it is best to minimize the opportunity to contact with them, so in the laboratory to pay attention to the following points.

　　1, the environment is very important, try not to put too many drugs in the laboratory, especially volatile materials, no special requirements for each experiment as little as possible to throw material. The laboratory should be cleaned every day, and the spilled chemicals should be cleaned up in a timely manner.

　　2, the laboratory must maintain air flow, in addition to the need for strong exhaust air is also important, both in summer and winter, even in the use of air conditioning and heating, rather than hot and cold, laboratory windows should not be closed.

　　3, try not to use some very toxic chemicals. All operations are carried out in fume hoods, including material transfer and spin evaporation. Pay attention to inhalation and transdermal absorption, especially the respiratory organs, in the laboratory strenuous exercise will increase the absorption of organic substances, must pay attention to these points.

　　4, diligent hand washing, diligent hand washing, diligent hand washing, must be diligent hand washing, for corrosive substances, take to wear gloves, if necessary, but also have some protection to avoid getting on the skin, take to finish in time to wash hands and exposed skin. Do not pass gas through the respiratory tract, solids, liquids do not touch the skin, lab coats, gloves wash diligently, use highly toxic substances to wash every day. In addition, tell a little is usually best to rub some protective oil or cosmetics, they can close the pores to reduce skin absorption of organic substances, which is more beneficial to women.

　　5, to develop good operating habits to prevent accidents, and to learn how to deal with accidents, to prevent small things from becoming big disasters; to develop the habit of always paying attention to laboratory hygiene and safety, before using unused reagents to check their physical and chemical properties, the physical and chemical constants of the material to do a good job.

　　6, in addition to the usual maintenance is also very important, do organic synthesis work, no matter how you pay attention to the work are inevitably inhaled some toxic substances. How to detoxification has become a top priority, the first thing I tell you here is; try not to work continuously overtime, people have detoxification functions, the general reagents or do not be afraid, but must pay attention to rest to reduce the accumulation, fatigue will make our immune system exponentially reduced, reducing the ability to detoxify. Annual medical checkups, such as routine blood and urine tests, to keep abreast of their health status. The liver is the body's largest detoxification organ must be protected, it is best to inject hepatitis A, hepatitis B vaccine, with liver disease of the same people should pay more attention to the maintenance of the liver.

　　7, drink more water, it is best to drink more tea, many laboratory workers do so, more sweating can be detoxified through the skin, and then is more excretion.

　　8, especially important for people engaged in the chemical industry is to drink more milk, in addition to eat more pig's blood, seaweed, eggs, fruit juice, fruit, beans, fungus and other things, these things can be detoxified to a certain extent.

　　9, after doing the work, exercise, more exercise may be able to exhale the organic matter in the lungs, conditions and then take a shower, the organic matter attached to the skin is also washed off, less tainted with bad diet and lifestyle habits, alcohol can be less, but definitely not smoking!

　　In short, do organic synthesis must bear in mind: less poison every day! When using volatile drugs must wear a mask, in the experiment gloves do not leave hands! Do not always stay in the laboratory! More exercise, more sweat can be detoxified, swimming, climbing stairs, walking is a good choice!
