I have a Kidde dry chemical home fire extinguisher. It is at least

this mean it's still safe and can be relied on, or do these things
need to be replaced after awhile no matter what the gauge reads?

What I was told, not an expert:

Unlike other compressed gas cylinders, they aren't subjected to the
stresses of refilling, after emptying. So if the cylinder shows zero
signs of corrosion, the port is clear of any foriegn, and the guages
says the system is ready, then the fire extingisher should be OK.

Now IMHO, I would talk to your local fire company. They might suggest
something else.

Good luck,

"should be OK."


Keep it for a back-up and buy a new one.
