Are concentrated sulfuric acid pipelines now considered highly toxic? Then their pipeline classification also needs to be upgraded, including for flaw detection.

In HG/T20660-2017 \"Classification of Toxicity and Explosion Hazard Levels for Pressure Vessels\", sulfuric acid is considered an extremely hazardous substance, with the designation G1 for it. G1 refers to the highest level of carcinogenicity in IARC, namely a definite human carcinogen. According to GBZ230-2010, sulfuric acid is classified as a highly hazardous medium; in accordance with the \"Regulations on the Safety Supervision of Pressure Pipelines – Industrial Pipelines\" TSGD0001-2009, sulfuric acid pipelines are classified as GC1 pipelines.
What about dilute sulfuric acid? Does it also belong to GC1?
Yeh sulfate. I’ve heard in news reports before that some people have used sulfuric acid to commit disfigurement attacks; it’s scary!
This standard classifies sulfuric acid as moderately hazardous
