The issue of setting alarm points for toxic flammable gases
Thread Content
GB50493 specifies that the toxic gases referred to in these standards are those listed in the 2003 version of the \"Catalogue of Highly Hazardous Substances\", or toxic gases and vapors. However, there are some substances with toxicity levels that meet certain criteria but are not included in this catalogue; how then should alarms be set up for such substances, such as diborane?
You can only consult the local metrology and testing institute.
I think those that are listed in the 2003 version of the High-Value Goods Catalogue must be included, while those that are not should be added according to actual circumstances :)
