Argon is an inert gas, which has no direct harm to human body. However, after industrial use, the waste gas produced is very harmful to human body, which will cause silicosis and eye damage. Argon itself is non-toxic, but it has asphyxiating effect at high concentration. When the concentration of argon in the air is higher than 33 chickens, there is a danger of suffocation. When the concentration of argon exceeds 50%, serious symptoms appear, and when the concentration reaches above 75%, it can die within a few minutes. Liquid argon can harm the skin, and eye contact can cause inflammation.

Question 2: If three argon cylinders are installed, is it considered as transporting dangerous goods (including two full cylinders and one empty cylinder)?

Question 3: According to the international rules for the carriage of dangerous goods by sea, is argon a dangerous chemical? Argon itself is not dangerous, but if it is high-pressure argon (steel cylinder), it is a dangerous chemical-because even if non-toxic high-pressure gas rushes out or the container explodes, it is still dangerous.

Question 4: Is the mixture of carbon dioxide and argon 20 15 in the Catalogue of Hazardous Chemicals? Liquefaction? Liquefied gas belongs to pressurized gas, which is not clear in the list, but it is clearly pointed out in the list that one of the categories of pressurized gas belongs to dangerous chemicals in principle. The mixed gas itself is non-toxic and non-combustible. Similar to this situation, it is basically a scratch, and there is no application for relevant qualifications.

Question 5: Is argon arc welding steam dangerous? Argon is an inert gas and will not burn, so there is no fire danger.

But too much argon will make people suffocate and suffocate, which is very dangerous.

I hope my answer is useful to you. If satisfied, please click ~.

Question 6: Is the argon cylinder dangerous? Can argon be transported in oxygen cylinders? Argon is a dangerous chemical, and argon bottle is a special equipment, because argon is an inert gas and can be transported by oxygen bottle.
