Does fuming sulfuric acid under GB 18218 version 18 no longer fall under the category of substances that require identification as major hazard sources?
Thread Content
Table 1 of GB 18218 version 18 has removed chemicals such as \"fuming sulfuric acid\" that are inconsistent with the criteria for classifying major hazard sources; does this mean that fuming sulfuric acid is no longer considered a substance subject to major hazard source labeling? Both fuming nitric acid and concentrated nitric acid (greater than 70%) are.
In the revised Version 18 of GB18218, fuming sulfuric acid is not classified as a substance representing a major hazard.
