    See Section 500.6(A)(4). You also should review NFPA 497 as referenced in the Informational Note to obtain the “T-Code” required in Sections 500.8(B) and (C)(4).

    Group A = Acetylene
    Group B = Hydrogen (and similar)
    Group C = Ethylene (and similar)
    Group D = Propane (and similar)

    Group D often means the location has methane or propane.
