Just to reinforce what MPI said...
I am an active member of SAVTA and an ALOA CPL. I won't say much in reference to these safes, since a previous thread where I went into detail on why specific safes were garbage was mysteriously deleted, but I will say this: even though the word "safe" is not defined, that doesn't mean you can use any old box just because it has a lock on it. The terminology was most likely purposely left ambiguous so that when it comes down to it, the crown will have its "experts" decide what is and what is not a safe in each specific "improper storage" case.
Forget about any other "organization" or standard. No "expert" will ever try to say that using a
UL-listed container was "improper storage". So if you are buying one container to "meet the minimums"
make damn sure its a good one. Even if you buy a cheap UL-listed container like those crappy tire Sentry/Garrison boxes, the fact that it is only UL listed for "fire protection" and not "burglary protection" PLUS it has a non-UL listed key lock on the container may open you up to prosecution.
Physical security devices are covered under Underwriters Laboratories STP #687. If there is any type of auxiliary (aka override) key lock on your container, make sure it meets
UL 437. If your container's sole locking mechanism is by key, make sure it meets
UL 786. If there is a combination lock on your container, make sure it meets
UL 768. If there is electronic lock on your container, make sure it meets
UL 1034. The container as a whole should meet
UL 687. I wish I could give you more details on what those standards require, but UL has chosen to make people pay for that information. Your local library may have a book with details on UL standards. Just keep in mind that any container that is UL listed will have the logo and standard # displayed. If you have to ask if your container is UL-listed, it most likely isn't. UL listing is a big selling point, so it should be pretty obvious when making a purchase.
Remember, just because your container may be UL-listed for "FIRE PROTECTION", doesn't make it a safe. It makes it a FIRE BOX. You should meet the abovementioned BURGLARY PROTECTION standards to make sure your box qualifies as a "safe".
In my professional opinion, this is what I tell everyone who comes to me asking about firearm storage, the ambiguity of the law is
not an invitation to use whatever you can scrape up. It is
the main reason you should go above and beyond. Firearm storage is no joke. I cringe when I hear people talking about "meeting the minimum" and talking like the government is inconveniencing them because they insist on proper storage procedures. What a stupid thing to say. Like leaving a gun on your kitchen table is okay because you have a tight leash on your kids? What kind of logic is that?
