Environment hazards: this substance is harmful to the environment, especially the water pollution.
Blasting danger: flammable, its vapors can form explosive mixtures with air, and has explosion hazard in the event of fire, heat combustion
侵入途径：吸入 食入 经皮吸收
健康危害：高浓度苯对中枢神经系统具麻醉作用，可引起急性中毐并强烈地作用于中枢神经很快引起痉挛：长期接触高浓度苯对造血选系统有损害，引起慢性中毐。对皮肤，粘膜有刺激、至敏作用。可引起出血性白血病。
