Why no instructables on constructing a Fammables storage box? Answered

I need a box for storing the gas can and other flammables in your garage or shop?



Best Answer 8 years ago

The flammable storage containers at my work are made of double-layer steel with an inch gap between the two layers.  All of the seams on the doors overlap.  There is a built-in vent that can be adjusted.  It also has a built-in safety feature, that locks the box closed if the contents inside catch fire.

Perhaps this is something you could build, with appropriate machine tools and a welder.

Have you looked into commercial units?

I am like most people who just have the gas can sitting in a corner of the Garage or work shop.  Years ago one of the wood working magazines had an article on building your own.  Construction was wood and two layers of fire shield drywall.
I realize that nothing home made will meet any type of safety specs, but it could be better than nothing at all.

Yeah, I've got my small gas can stored in a wood shed.  I'm just asking for trouble!  That's a cool idea with a wood and drywall, though.  I've got lots of scraps left over from renovations, maybe I should build one.

I believe the fused link that closes the lid is actually designed to close on an external fire.  I originally thought these containers were to contain any fire in the flammable materials but now understand it is to keep the contents cool in a building fire and prevent or delay the materials from catching fire or exploding.
Not an expert but something I remember from prior research.

Because meeting NFPA, OSHA, ANSI, and ISO standards for construction, including the performance of testing to certify that those standards have been met, are beyond the capability (and cost!) of the do-it-yourself community.

if you don't care about meeting safety standards, use a solid (welded) metal box.

If you do care about meeting safety standards, purchase a commericial flammables locker with the necessary certifications.

If your serious about it, the storage needs to comply with certain specifications. Start researching.

Because you haven't written it yet?
