Restaurant Extinguishers: Do You Have the Right Ones?
Everyone knows you need extinguishers in restaurants, but which ones and how many is where some people get lost.
A customer with a commercial cooking operation (restaurant), inform you that all buildings have Class A fire hazards and that you will be installing multi-purpose dry chemical extinguishers throughout the building. Let you know that these extinguishers are ABC rated and are intended for all fires, except cooking grease. The main thing is to let you know there will be no point more than 75 ft from an extinguisher.
Your next step is to install extinguishers for the additional hazards. The cooking areas of restaurants need special extinguishers. Every appliance that uses cooking oil needs Class K extinguishers. This includes deep fat fryers, griddles, and stove top pans. In simple terms, Class K extinguishers are required for the protection of these cooking appliances because of the special fire hazards related to them.
NFPA 10 says you need an extinguisher within 30 ft of these appliances. Just remember not to double up on the extinguishers unless the restaurant owner requests additional extinguishers. The trick is “travel distance” from an appliance to an extinguisher. NFPA 10 has the following requirement for Class K Hazards:
6.6.2 Maximum travel distance shall not exceed 30 ft (9.15 m) from the hazard to the extinguishers.
Place the Class K extinguishers so that they protect several appliances. If you have two or three appliances and you can put one Class K extinguisher within 30 ft of those appliances, you’ve covered the hazard. You don’t need an extinguisher for each appliance, just one within 30 ft. But often times there are multiple cooking stations, so make sure each station has a Class K extinguisher within 30 ft.
Always remember to install a sign that says to dump the extinguishing system prior to using an extinguisher. NFPA requires these signs be installed for each Class K extinguisher.
For restaurants, always anticipate installing ABC dry chemical extinguishers for building coverage and Class K extinguishers for the cooking area, and don’t forget the signs for the Class K. With these simple tips, you should be able to provide the right type and number of extinguishers for your restaurants and make sure you are code compliant for extinguisher coverage.
Thank you.
