Occupational acute benzene poisoning is a systemic disease mainly manifested by central nervous system inhibition caused by workers inhaling large doses of benzene vapor in a short period of time during occupational activities. Occupational chronic benzene poisoning refers to a systemic disease with hematopoietic system damage as the main manifestation caused by workers' long-term exposure to benzene vapor in occupational activities. Low concentration of benzene in the air can cause benzene poisoning by inhalation through respiratory tract or direct contact with benzene and its mixture through skin.

Replacing benzene-containing raw materials with benzene-free raw materials is the key to prevent benzene poisoning.

On-site protection of benzene operation is mainly to strengthen ventilation and personal protection of employees, and workers can wear gas supply gas masks or gas masks. Patients with hematological diseases, liver and kidney diseases and asthma are not suitable for benzene operation.

Use non-toxic or low-toxic chemicals such as toluene instead of benzene as solvent: ventilate and detoxify; It is forbidden to wash hands with benzene; Wear a gas mask when exposed to high concentration benzene vapor. In case of acute poisoning, the patient should be moved to fresh air quickly, keep the respiratory tract unobstructed, take off the clothes contaminated by benzene immediately, rinse the contaminated skin with soapy water, and keep warm; People who stop breathing and heartbeat should be given artificial respiration immediately. Once benzene poisoning is diagnosed, you should get rid of benzene exposure. Besides active treatment, you should arrange rest properly.
