Toxicity standards of TSG D0001-2009
Thread Content
The TSG D0001-2009 \"Regulations on Safety Supervision of Pressure Pipelines\" adopts GB5044 as the standard for material toxicity, but now GB5044 is no longer in force; which standard should be followed then? GBZ230? This standard’s preface also does not state that it can replace 5044. I have to complain: with our **standard where each party handles things on its own, the overlapping areas are so unclear that it’s really frustrating:dizzy:
I believe GBZ230 is a standard set by the Ministry of Health, and it provides formulas; therefore, calculation errors may occur

The preface of \"GBZ 230-2010 Classification of the Hazard Level of Occupational Exposure to Toxic Substances\" explains clearly that it is \"GBZ 230-2010 Classification of the Hazard Level of Occupational Exposure to Toxic Substances\" that replaces \"GB 5044-85 Classification of the Hazard Level of Occupational Exposure to Toxic Substances\". For your reference
I believe that the criteria for assessing the toxicity of substances are detailed in Appendix A of TSG D0001-2009; when classifying pressure pipelines, there is no need to consider GB5044 or GBZ230 – TSG D0001-2009 can be used directly.
