Store the aerosol fire suppressant where it is convenient and out of the reach of children, but not too near areas that pose fire hazards. For example, do not store it in the cupboard above the cook top where you would have to reach toward the grease fire just to retrieve the suppressant. Once the aerosol suppressant has been used to any extent, replace it as you would a disposable conventional fire extinguisher. The aerosol can may feel "full" or close to it, but don't take the chance. Check the expiration dates on a regular basis, perhaps on the same dates that you test your smoke/fire alarms. Understand that an aerosol fire suppressant does not replace the need to have a larger and more powerful conventional fire extinguisher for larger jobs.
