After benzene exceeds the standard, we must take active measures to reduce benzene. If the benzene standard is exceeded in the environment, when people inhale a large amount of benzene, it can seriously threaten people’s health. There are acute and chronic benzene poisoning, and in serious cases, it can damage liver and kidney and endanger life. Generally, the main measure to reduce benzene in the environment is to open the windows to let the air form natural convection, which can reduce benzene very well, and it is inexpensive and has little cost. You can also use ventilation and air conditioning system or new air system for mechanical ventilation, which can reduce the benzene content very well. In addition, the method of benzene reduction can also use instruments, such as photocatalysts and other instruments to remove benzene, which can also very well control the content of benzene in the environment. People who work in benzene environment should strengthen nutrition, pay attention to rest and improve physical fitness to prevent benzene poisoning.
