Determine which code requires Class K fire extinguisher placarding near commercial kitchen fryers

Steps

1. Identify the two overlapping requirements: NFPA 96 requires every portable fire extinguisher located in the cooking area to have a placard demonstrating its proper use, while NFPA 10 specifically requires a placard on Class K extinguishers instructing that the fixed fire suppression system be activated before using the portable extinguisher
2. Confirm the placard's required wording for Class K units follows the NFPA 10 language (activate the automatic/fixed suppression system first, then use the Class K extinguisher only if that does not control the fire)
3. Verify the placard is conspicuously placed at or near the extinguisher itself, not just posted elsewhere in the kitchen
4. Confirm portable extinguishers in the cooking area use agents that saponify on contact with hot grease (e.g., wet chemical Class K agents, or approved dry chemical types); Class B gas-type portables such as CO2 are not permitted in cooking areas under NFPA 96
5. Check both NFPA 96 and NFPA 10 placarding language against the specific editions adopted locally, since exact wording requirements can be refined between editions
