Tiandi first and introduce emergency measures for ammonia leakage
(1) A small amount of leakage.
Retreat all personnel in the area. Prevent inhalation of vapors and contact with liquids or gases. Disposers should use a respirator. It is forbidden to enter the confined space where ammonia gas may be collected and to enhance ventilation. It can only be blocked if it is safe. Leaked containers should be transferred to a safe location and the valve relief should only be opened if safety is ensured. The leakage material can be collected and adsorbed by inert absorbent materials such as sand and vermiculite. The collected spillage should be placed in a closed container with the appropriate label for disposal.
(2) A large number of leaks.
Dislocate all unprotected personnel in the site and transfer them upwards. The leaking personnel should wear a fully enclosed heavy chemical protective suit and wear an air breathing apparatus. After personal protective measures are taken, the leaking area is diluted with a spray water flow. Through the dilution of the water gun, the ammonia gas on the site is gradually dispersed, and the leak point is blocked by the non-sparking tool.
Report to the local government and the “119†and local environmental protection departments and public security traffic police departments. The content of the alarm should include the accident unit; the time and place of the accident, the name of the chemical and the amount of leakage, the degree of danger; the presence or absence of casualties and the name of the alarm person, phone.
It is forbidden to contact or cross the leaked liquid ammonia to prevent leakage into the gutters and drains and enhance ventilation. No smoking or open flames are allowed in the premises. In case of safety, it is necessary to plug or flip the leaking container to avoid liquid ammonia leakage. Spray water to suppress steam or change the flow of the vapor cloud, but it is forbidden to directly impact the leaked liquid ammonia or leak source with water. Prevent spills from entering water bodies, sewers, basements, or confined spaces. It is forbidden to enter a confined space where ammonia gas may collect. After cleaning, all protective clothing and equipment should be removed before storage and reuse.
