What a kitchen fire spray can and can’t do

The little aerosol fire spray in the kitchen drawer may not last as long as homeowners expect. According to Consumer Reports, the cans carry only about a three-year shelf life — far less than the six to twelve years of a traditional extinguisher — and they have no pressure gauge, so there is no way to confirm one is still charged. The date is printed on the can; note it and replace on schedule.

The sprays do have real virtues. There is no pin to pull, just point and spray, and they are rated for grease and cooking-oil flare-ups, which makes them easy to grab in a hurry. But they are a backup, not a replacement. The label itself states the spray does not meet NFPA 10, the standard for a true fire extinguisher.
