Now I will introduce you to the disinfectant commonly used in the import and export of dangerous goods containers-chlorine trifluoride.
Chlorine trifluoride is a Class 6.1 hazardous chemical, UN 1749, molecular formula ClF3, melting point -76.3°C, boiling point 11.3°C. It is toxic and highly corrosive. It is a colorless gas at room temperature, and becomes a green liquid after cooling and liquefaction. The relative air density in the gaseous state is 3.14. It is one of the most active compounds known. It can erode the glass immediately. It also corrodes quartz when there is moisture. It reacts violently with water to explode, and reacts with organic matter.
ClF3 is a very strong oxidant and fluorinating agent. It can react with most organic and inorganic materials and even plastics, and can make many materials burn without contacting the fire source. These reactions are usually violent and in some cases can even explode. It reacts with some metals to produce chlorides and fluorides, reacts with phosphorus to produce phosphorus trichloride and phosphorus pentafluoride, and reacts with sulfur to produce sulfur dichloride and sulfur tetrafluoride. ClF3 also reacts violently with water, and hydrolysis produces toxic substances, such as hydrogen fluoride. H2S will explode when mixed with ClF3 at room temperature.
Because of its ability to surpass the oxidizing power of oxygen, it results in corrosiveness to oxygen-containing materials, which are generally considered non-flammable. In an industrial accident, a 900 kg ClF3 leak burned itself through 30 cm of concrete and 90 cm of gravel. Any equipment that comes into contact with chlorine trifluoride must be carefully selected and cleaned, because any ClF3 contamination may ignite the contact.
Chlorine trifluoride is extremely dangerous because of its lively nature. It is necessary to control the safety of chlorine trifluoride through the following methods: First, employees are required to wear labor protection equipment as required during inspections; Unloading to prevent spills from packaging damaged goods caused by bumps; three strict control of combustible materials around to avoid disasters. Four security officers conduct inspections every two hours and report any abnormalities in time. Through the implementation of the above measures, you can ensure that the goods are safe and controllable.
