What should you pay attention to when using strong acids? answer: (1) Rubber gloves should be worn when using strong acids ； (2) Glass products such as measuring cylinders are required when measuring strong acid. (3) When diluting strong acid, be sure to slowly pour the concentrated acid into the water along the wall of the container and stir while pouring. Never pour water into the strong acid. 4. What precautions should be taken when using high-pressure cylinders? answer: 1) High-pressure gas bottles must be stored in categories and labeled according to gas type. 2) Store gas cylinders in a cool, dry place. Keep open flames away from heat sources and prevent exposure to the sun. 3) Handle the gas cylinder with care and do not knock it or shake it violently. The bottle body has two anti-shock rubber rings. It is strictly forbidden to roll the acetylene bottle horizontally. Gas cylinders should undergo regular technical inspections and pressure tests. 4) The pressure reducing valve for high-pressure gas cylinders should be dedicated. Oxygen and hydrogen pressure reducing valves should be distinguished, and there should be no air leakage at each connection. 5)|The gas in the bottle must not be completely exhausted, and a residual pressure of (0.2-1.0) MPa should be maintained to prevent danger. Hydrogen bottles and oxygen bottles must not be stacked close to each other to prevent danger. 　6) This sample point is easily blocked and is equipped with a steam purge pipeline. It must be operated in order. 5. What are the general principles of fire fighting? answer: 1) If you call the police early, the loss will be less, and you can call the police and put out the fire at the same time. 2) Control first, then put out the fire, save people first, then save things. 3) If there is room poisoning, prevent suffocation, listen to instructions and don’t panic.
