What are the safety hazards of car sunroofs?
1 Answers
The safety hazards of car sunroofs are as follows: 1. The broken glass fragments from the sunroof pose a safety risk. The glass used in sunroofs is tempered film, and through special internal stress design, it does not produce particularly large fragments when broken, eliminating direct fatal danger. However, the resulting glass fragments still carry certain safety risks, as they can easily cause harm to our mucous membrane organs. 2. Tempered glass may shatter even without external force. Even without external force, tempered glass can shatter on its own due to its manufacturing process, which makes it prone to impurities like nickel sulfide. Nickel sulfide crystals are sensitive to temperature, and their volume changes with temperature variations. Sometimes, an excess of impurities can lead to spontaneous sunroof explosions, with an industry average spontaneous explosion rate of about 3.4‰ to 5.4‰, posing risks once shattered.
