Firearms
Any strategy that builds some time between someone and a gun in a suicidal crisis will keep them safer. Ask a friend to hold your keys, or store the keys somewhere they’re not available in a crisis like a bank safe deposit box.
Lock
Store guns safely and securely when not in use. Change your gun locks if necessary, and make sure the keys and combination aren’t accessible.
Limit
Lock guns and ammo separately, or don’t keep ammunition in the home at all. Ask to temporarily keep the keys to any gun of a friend who is struggling.
Remove
Temporarily store firearms off site until the situation improves, perhaps at a friend or relative’s house. Gun shops and law enforcement may offer storage options.
