What are the differences between poisoning and accidental first aid?

The general first aid pre-process and basic vital sign assessment logic do not fall into the distinction between poisoning and accidental first aid at all, and are common requirements that must be followed in all first aid scenarios. I have been doing practical first aid training in the community for almost four years, and I have seen many novices classify operations such as "check the environmental risks of the scene first" and "call 120 for help first" as the unique steps of a certain type of first aid. In fact, this is not the case at all - take last week's simulation exercise as an example. A group of trainees were drawn into a scene of organophosphorus pesticide poisoning, and they wanted to rush to lift people. Ignoring the scattered pesticide mist, the other group encountered an accidental scene of being injured by a falling object from a height. Instead, they stood downstairs to confirm whether there was a secondary falling object. As a result, when the two groups were commenting on each other, someone actually said, "You don't need to check the environment for first aid in poisoning." This made me angry. Think about it, if the poisoning scene is a gas leak, if you don't turn off the valve to ventilate first, and go in and pour one after another, who are you going to save? In this step, no matter what the first aid scenario is, it comes first, and there is no difference at all.

The same applies when you encounter a specific patient. Whether you encounter a poisoned patient who ate poisonous mushrooms or an accidental victim who was hit by a car on the road, when you arrive at the scene, you will feel the carotid artery as soon as possible to see if there is spontaneous breathing and whether the consciousness is clear. The evaluation logic is exactly the same. It cannot be said that poisoned patients do not need to check whether they are breathing first, right? There is still some controversy in the industry over the operations related to "removal of foreign bodies in the digestive tract." Many old textbooks previously listed induction of vomiting and gastric lavage as the core differences between poisoning and accidental first aid. However, in recent years, more and more clinical cases have been accumulated, and everyone has also found that if the patient drinks strong acid, Corrosive poisons such as alkali can induce vomiting and repeatedly burn the esophagus and airway, so they must not be used. If the accidental victim accidentally swallows a sharp foreign body, the corresponding digestive tract foreign body removal operation must be performed, so now this is increasingly not listed as an absolute difference between the two.
