2, xylene chronic poisoning: there will be neurasthenic syndrome, women can lead to abnormal menstruation, skin contact can occur dry skin, chapped, dermatitis.
Xylene protection measures
Respiratory system protection: When the concentration in the air is high, wear a filter gas mask (half mask). During emergency rescue or evacuation, it is recommended to wear an air respirator.
Eye protection: Wear chemical safety glasses.
Body protection: Wear protective work clothes.
Hand protection: Wear rubber gloves.
Others: Smoking, eating and drinking are prohibited on site. After work, shower and change. Pay attention to personal hygiene.
