Gas analysis must be conducted on towers and container equipment before hot work; the analysis is considered satisfactory when the total amount of flammable gases is ≤ (B, 0.5%).
Gas analysis is considered satisfactory when the total amount of combustible gases ≯ (C, 1%)
Gas analysis must be conducted on towers and container equipment before hot work; the analysis is considered satisfactory when the total amount of flammable gases ≯ (A).
The ontology can only be B. It should be \"When the lower explosion limit of flammable gases is >4%, an analysis result of <0.5% is considered acceptable.\" ； When the lower explosion limit of the combustible gas is ≤4%, an analysis and testing value of <0.2% is considered acceptable.
Gas analysis must be conducted on towers and storage vessels before hot work; the analysis is considered satisfactory when the total amount of flammable gases ≯ (C). A、0.3% B、0.5% C、1% D、2%
For Tower B and container equipment, gas analysis must be conducted prior to hot work; the analysis is considered satisfactory when the total amount of flammable gases is ≤ (0.5%).
