I've got two...they both expired about two years ago!
This happened to some friends who were competing here in Michigan a few years ago.
Don't skimp on Fire Extinguishers. My neighbor's site in Sayville has caught on fire twice in 2 years so I always keep a decent sized one handy.
Hmmm...I think there might be a reason your "neighbors" are catching on fire.:smile:
Are they the throw away type with a plastic head or with a metal head?
If they are metal you should take them to a reputable fire extinguisher shop and have them recertified.
Just my 2 cents here.
