1.Respiratory protection: when the concentration is high in the air, choose the self absorption filter gas mask (half mask) or air breathing apparatusit according to  the concentration of the pollution gas and whether the operating environment is lacking oxygen or not .
2.Eye protection: wear chemical safety goggles.
3.Body protection: wear anti-static work clothes.
4.Hand protection: wear general protective gloves.
5.Other:No smoking. Avoid high concentration of inhalation.
