Chlorine mainly acts on trachea, bronchi, bronchioles and alveoli, leading to corresponding lesions. When the concentration of chlorine in the air reaches 10mg/m3, it will produce strong irritation, and the poisoned person will have mucous membrane irritation, such as tears in the eyes, conjunctival congestion, tingling, burning sensation in the nasopharynx and cough; When the concentration rises to 100-180mg/m3, people will suffer serious damage after 30-60min contact, which is manifested by persistent choking, chest urgency, hoarseness, and sometimes chemical pneumonia; When the concentration rises to 300mg/m3, the poisoned person may suddenly faint and lose consciousness. If there is any untimely rescue, life may be in danger; Higher concentrations can cause instant death. It should be pointed out that skin exposure to high concentrations of chlorine can cause burns or acute dermatitis.
Emergency treatment procedure after chlorine leakage:
1. First of all, a capable rescue team should be set up to quickly enter the dangerous area with life-saving equipment, search for trapped or poisoned and unconscious people, and notify people within a certain range of downwind to take protective measures and move upwind; Secondly, take the correct rescue method to transfer all the people in distress to the safe area; Third, the rescued personnel should be registered, identified and given first aid on site, and the injured should be sent to the hospital for treatment.
2. When entering the leakage site for leakage treatment, the whole body must be isolated and protected, and air respirators must be worn. For the leakage source of large tanks, the valve shall be closed first to cut off the leakage source; For small steel cylinders, if necessary, they can be moved out of the warehouse and immersed in lime water in an open area to fully react with chlorine. For the leakage of chlorine storage tank in large workshop, the following measures shall be taken: (1) Start Chlorine trap According to the plan, the rescue team quickly transported the vehicle to the leakage site, implemented neutralization and rescue, and rapidly reduced the chlorine concentration. (2) Laying water curtain, dilution, degradation site and surrounding chlorine concentration; If possible, use low concentration alkaline water for neutralization and dilution, and the effect is better. (3) Multiple spray water guns are used to form a water curtain wall to prevent chlorine from spreading to important targets or other hazard sources.
Therefore, Zibo Dazheng Chemical Co., Ltd. reminds all units using chlorine gas to equip Chlorine trap
