Standards are referenced throughout the Ontario Fire Code.  It is important to understand that different versions of the standards are referenced.  For example, the Ontario Fire Code references NFPA 10 - Portable Fire Extinguishers but the reference is NFPA 10-2010 which calls all requirements in the 2010 version of the standard into the legislation and as a result all requirements of the 2010 version are fully enforceable by an inspector.

Beware when purchasing fire safety equipment requiring standards.  Purchasing off-shore equipment from a unknown source may result in false standard compliance as the item has not been approved for use in North America.  If you come across a item with suspect origin, contact NBFES, discontinue use and purchase a replacement from a reputable seller.
