If a patient accidentally gets a fiberglass laceration to the hand at home, self-sterilization and self-help should be performed quickly at this time, and after the self-help is completed, the next step of disposal should be to the hospital. It should be rinsed off with water or mineral water and then the wound should be glued with adhesive tape from home, which can be torn off quickly afterwards. In general, glass fibers are capable of automatic adsorption, and most peeling fibers can be removed by themselves through repeated adhesions. In addition, treatment should be given promptly at the hospital. Upon arrival, the emergency department doctor will thoroughly debride the area, pick out the remaining glass fibers by pricking and other means, and then disinfect the area with iodophor to avoid secondary infection of the wound.
