[Milsurplus] OT: Kidde fire extinguisher recall

[Bill Cromwell]

Hi,

Those should be serviced every couple of years or so. The tech will open 
them replace the chemicals and repressurise them. They can go a lot 
longer if somebody remembers to faithfully shake them up 
periodically..maybe every month of so. Whne powder eventually cakes they 
become useless. Shaking them up keeps that from happening - not causing it.
