At about 11:20 p.m. on August 12, an explosion occurred at a dangerous goods warehouse belonging to Tianjin Port Ruihai Company. In this painful and heavy node, we saw the “disaster is merciless, love full of Jincheng”, heard the “great love, the heart of a party”, some people praise “the most handsome retrograde, the most beautiful people “, someone praised “full of positive energy, praise for Tianjin people, pray for Tanggu”. As an ophthalmologist, in my mind, firefighters and doctors are occupations with the same social attributes, and they are both guardians of life. While I was touched by their recklessness and courage, I was more concerned about the eye injuries of firefighters in the explosion. How to carry out the most formal and effective prevention? Explosions can cause a variety of injuries to the human body, in addition to the most serious life-threatening, the face and eyes are also the most vulnerable organs. Some injuries should be examined after leaving the scene safely, even if there are no obvious symptoms at the time. In this incident, it was reported that a member of the Tianjin Seaport Fire Brigade was injured in the cornea during the rescue. First, what kind of injuries may be sustained to the eye in an explosion? High-temperature gas, liquid or solid can cause the eye conjunctival tissue congestion, edema, superficial corneal damage; severe burns can even cause conjunctiva, sclera and corneal pallor, necrosis. The explosion produces high temperature and release of large amounts of gas in a short period of time, the destructive force is very strong. The explosion caused by the shock wave carrying the glass, wood chips, iron filings and other foreign objects splashed into the eyes can lead to serious eye injuries. Second, what are the most formal and effective equipment for firefighters? In the United States, the National Fire Prevention and Control Administration (NFPA), a professional organization dedicated to the scientific protection of firefighters, found in its study of 3830 eye injuries in firefighting incidents throughout 1997 that the majority of injuries could be prevented by effective eye protection. The NFPA has also established a series of eye protection standards to prevent eye injuries during emergencies. Protective equipment for the eyes and face includes glass glasses, goggles, and face shields. The current NFPA standard for the quality of these devices is ANSI Z87.1, with 1,500 details, developed by the American National Standards Institute (ANSI), which specifies special requirements and evaluation factors, such as impact tolerance, lens thickness, and lens Optical quality, etc.
