Symptoms of hydrogen cyanide poisoning?

summary

Hydrogen cyanide is a colorless, toxic liquid with a boiling point of 26 ℃ (79 ℃) ° F) Slightly higher than room temperature, hydrogen cyanide vapor, or hydrogen cyanide gas, is a highly toxic gas, causing great harm to people. Therefore, we must always pay attention to the concentration of hydrogen cyanide in the air when we produce and use hydrogen cyanide. The main function of the hydrogen cyanide toxic gas alarm is that when the hydrogen cyanide reaches a certain concentration in the air, the hydrogen cyanide toxic gas alarm will give an automatic sound and light alarm to remind the staff to take corresponding measures in time to avoid poisoning accidents. So what are the symptoms of hydrogen cyanide poisoning? Let's talk about it.
