have a very basic fire ext tip I have discovered I can buy reconditioned fire ext on e bay for about the same price as a 5 yr insp on my old ones shipped to my door with tags hydro test & whole 9 yds/ new brackets & sign inc. local inspectors accept them & old 1s which are generally still ok I use in my car, trucks, shop etc. so I sorta get 2 4 1. works 4 me

In Los Angeles we have to have Fire Extinguishers inspected every year and new tags placed on them for rental properties. Then every 5 years they have to be hydro tested.

I can either have a company come out and conduct the service or bring them into their shop for service. I just can't remove them from one building and leave the tenants without a replacement. So I have extras.

Extinguishers have size and ratings, A, B and C. Depending on what materials they are trying to put out the flames. Paper, wood, fluids, oils, etc.

The junk we buy from a big box store have plastic tubes that go down into the body of the extinguisher and can break off easily. I only get the commercial with metal parts, they last longer.
