The reference answer can be seen after replying; points will be awarded for identifying the key points. (Unless otherwise specified, all questions and answers are based on hydrogenation units.) Gasoline has a very low flash point, and it releases large amounts of flammable vapor at room temperature. When using gasoline to clean mechanical parts, friction generates a lot of heat and static electricity. As the heat increases, more flammable vapor is released, and when this vapor mixes with air, it can form an explosive mixture. Moreover, repeated friction leads to an accumulation of static electricity; once these two factors come into contact during the cleaning process, a high voltage difference is created, which can result in discharge and ignition, potentially causing an explosion or fire. Therefore, using gasoline to clean mechanical parts is very dangerous. Similarly, using gasoline to clean floors is also unsafe. Scoring criteria: 2 Wealth points for incorrect attempts; 3–8 points for *incomplete* answers. 10 Wealth points for correct answers, provided with a detailed explanation; 15–20 Wealth points if the answer is correct but lacks sufficient details. Please score according to these criteria. Note: If there are editing records after answering, only those who participated will be given points. For continuous malicious spamming, 2 points will be deducted each time, with no upper limit. Pure numbers, pure emojis, or random letters unrelated to the answer are all considered malicious spamming; points will start to be deducted after three warnings. 2017 Q&A Summary Thread (updates starting now) http://bbs.hcbbs.com/thread-1657793-1-1.html 2017 Daily Question Summary Thread (updates starting now) http://bbs.hcbbs.com/thread-1657794-1-1.html 2016 Q&A Summary Thread (updates completed) http://bbs.hcbbs.com/thread-1597792-1-1.html
Gasoline is highly volatile and can easily catch fire when exposed to an open flame
Gasoline has a very low flash point, and it releases large amounts of flammable vapor at room temperature； A large amount of heat and static electricity is generated due to friction; as the heat increases, flammable materials can be affected ；

Moreover, repeated friction leads to an accumulation of static electricity; once this electricity is discharged at a certain distance during the cleaning process, it can cause an explosion or fire. Therefore, using gasoline to clean mechanical parts is very dangerous, and it is also unsafe to use gasoline to clean floors.
Gasoline is highly volatile and can easily form explosive mixtures with air. It also has a very low flash point and requires little ignition energy, making it prone to catching fire when exposed to sparks.
Because gasoline is volatile, it can form explosive mixtures that cause fires or explosions.
