毒理性

• 解毒与急救

立即急救：确保已经进行了充分的中毒物清洗。如果患者停止呼吸，开始人工呼吸，最好使用需求阀复苏器、袋阀面罩装置或口袋面罩，按训练操作。根据需要执行心肺复苏。立即用缓慢流动的水冲洗受污染的眼睛。不要催吐。如果患者呕吐，让患者向前倾或置于左侧卧位（如果可能的话，头部向下）以保持呼吸道畅通，防止误吸。保持患者安静，维持正常体温。寻求医疗帮助。/硫和相关的化合物/

Immediate first aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand-valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR as necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep patient quiet and maintain normal body temperature. Obtain medical attention. /Sulfur and related compounds/
