I know there is only a 5 year warranty, but does anyone know how long it can be expected to last & still work?

We have a local free medical clinic that has three 5 pound extinguishers dating to 2013. Our most recent inspection revealed that each had a lable specifying a more involved inspection at the 6 year point. So our fire inspection company took the three back to their lab where (I think) they will do a much more involved inspection of the valve, trigger, contents, etc. Perhaps this is overkill .. I dunno .. but maybe just a pressure guage still being in the green (as my three personal small 30 year old extinguishes shows) is not totally reliable of readiness to use.

Is this unit the safest for grease fires in kitchens?

Some fire extinguishers have toxic chemicals but this is sodium bicarbonate. It won't poison your kitchen if you use it. I like to keep an open box of baking powder next to the stove as an initial step in case of a grease fire. You can also smother it with another larger pan if the fire is confined to a pan. If that isn't possible, the best method is to take this can and step back a few feet, then spray the area and it should smother the flames. Don't get too close because the pressure might send the burning grease flying about. I keep a high-pressure fire extingusher in addition to this. But it has toxic chemicals and might splash burning grease/oils.

Before I purchase this I want to make sure it is safe to use on gas ranges/ovens.

The bottle says BC . Type B is for flammable Liquids such as gas or oil, type c is for electoral fires. If you want soemthing for grease fire use a type k. Or keep the lid of the pot or pan close to put on it to smother the fire. Different types of fire require different elements of extinguishing it. Saw a comment that said about fire being fire and it should be able to take out all fire. This is wrong. Different types of fire need different types of extinguishing agent the wrong kind could not work or make it worse. Definitely use a type K fire extinguisher

How is this kitchen rated when its not class k? Class b-c is for flammable liquids and electrical fires. Class k is for grease fires.

Class k is for commercial kitchens. That means large grease fires and industrial hood vent systems. So unless you have a deep fryer at home you probably don’t need class k.
