A pizza shop has a class K extinguisher within 30 feet of a commercial cooking hood Type 1and a suppression system over a range. The class K is within 75 feet of all areas of the shop. Do they need to have an additional 2A extinguisher, ABC, for the rest of the shop? The class K has a 2A and K rating. I looked in IFC 2009 and NFPA 10, unable to find the answer. Any help?
