About MSDS~~~~~

This, this~~~ It was discovered a long time ago. . . . Why are the sections on first aid measures, fire-fighting procedures, emergency response to leaks, and operational precautions in the MSDS for these hazardous chemicals basically identical? For example, under First Aid: In case of skin contact, immediately remove the contaminated clothing and rinse the affected area with plenty of flowing water for at least 15 minutes. Seek medical attention. Eye contact----Immediately lift the eyelids and rinse thoroughly with plenty of flowing water or saline for at least 15 minutes. Seek medical attention. Inhalation----Immediately leave the area and go to a place with fresh air. Keep the airway clear. If there is difficulty breathing, administer oxygen. If breathing stops, perform artificial respiration immediately. Seek medical attention. If ingested—rinse the mouth with water and give milk or egg white to drink. Seek medical attention. It’s always these same words. . . . . . :Emergency response to L leakage: Quickly evacuate people from the contaminated area to a safe zone, isolate it, and strictly restrict access. Cut off the source of fire. It is recommended that emergency responders wear self-contained positive-pressure breathing apparatus and protective suits. Seal the source of leakage as much as possible to prevent it from entering confined spaces such as sewers and drainage ditches. Minor leaks: Absorb or adsorb with sand or other non-flammable materials. Large-scale leakage: Build dikes or dig pits to contain it ； Cover with foam to reduce vapor hazards. Transfer with a pump into a tank truck or a dedicated collector, and recycle it or transport it to a waste disposal facility for disposal. It’s always these same words at such times. . . . . . :L
What kinds of chemicals are you mentioning? ? Protective measures and first-aid procedures are established based on the physical and chemical properties of the substance. Just like hydrochloric acid and sulfuric acid, in the event of eye contact, it is of course necessary to rinse continuously with flowing water. . .
I think it’s normal; this is first aid, which is treatment for emergency situations. Naturally, whatever measures are readily available around us are used. For example: Skin contact – immediately remove the contaminated clothing and rinse with plenty of flowing water for at least 15 minutes. Seek medical attention. (Available water for production and daily use) Eye contact – Immediately lift the eyelids and rinse thoroughly with plenty of flowing water or saline for at least 15 minutes. Seek medical attention. (Units handling hazardous chemicals are equipped with eyewash stations.) Inhalation – Immediately leave the area and go to a place with fresh air. Keep the airway clear. If there is difficulty breathing, administer oxygen. If breathing stops, perform artificial respiration immediately. Seek medical attention. Ingestion----Rinse the mouth with water, and give milk or egg white to drink. Seek medical attention. Who can come up with a better way?
These are all measures established based on the hazards and properties of dangerous substances; they represent accumulated experience. For substances with similar properties or hazards, the treatment methods will certainly be similar as well. However, when comparing two different types of hazardous materials, the methods used will definitely differ.
This is a normal phenomenon; first aid measures are used in abnormal situations. If you work in a hospital, you can simply go to the hospital for treatment! Hehe, also, if the natures are different, different methods are employed; when the natures are similar, the same methods are used! If phosphorus trichloride gets on your skin, would you dare wash it off with water directly? That’s impossible; you need to wipe it with a dry cloth first, and then rinse it with water! So it’s not strange that these words are basically the same!
What’s strange about using the same method to treat substances of the same type? If you have a better method, you can use that too!
