30% hydrochloric acid is used in the reaction vessel; is it really necessary to install a toxic gas alarm for this acid?

You didn’t make it clear – are there any other organic substances or something like that?

Pure hydrochloric acid should probably not be used; if a strengthening agent is involved and chlorine gas is generated, then it is necessary to use it. If a large amount of heat is released or a large quantity of acid mist is produced due to bubbling under the liquid, it is likely that this acid as well will be needed. The most important thing is to have a basis for this – what is the allowable concentration of hydrogen chloride, and what level of concentration might occur at the site?

Hydrochloric acid is not a toxic substance; then why is a toxic gas alarm needed? !
