Good guess. [Section 500.4 (B) IN No.2] However, since it is in an Informational Note (IN), it is technically nonmandatory. But you would be hard put to ignore it without a very strong argument for a different basis.
NFPA 45, Standard on Fire Protection for Laboratories Using Chemicals is the actual laboratory document. [Also referenced in Section 500.4 (B) IN No.2]. NFPA 45 Sections 2.1 and 2.2 have mandatory references including both NFPA 30 and 70.
