The RCN also blew up Halifax a couple of times...(ok, only once was actually our fault.) So, Vol 3 ships is based on not letting that happen again.
Let's put heavy mats at the foot of the ladders as we move small arms ammo onboard....then in case someone drops a can, they won't damage the deck nor the ammo can.
The rules I was given to consider were....overboard....so I twitted with them at one point. I was asked for my plan to re-ammo the ship with 680 rounds of SAA once as a part of our FP ammo loadout. Moving it from D-40 to the jetty.
The 'safe' method was to have the ship's truck swapped with a properly placarded vehicle borrowed from CFAD, escorted by a fire truck to ensure the ammo didn't spontaneously combust.
The 'backup' plan was to walk through the yard with the ammo can in hand, followed by a sailor carrying a water based fire extinguisher.
Those were COA 1 and COA 2. COA 3 was that I'd walk over, pick up the can, and bring it back to the ship.
All 3 COAs went to Formation Ammo, and they 'let' me do COA 3.
Realistically, you can stub out a cigarette with a 5.56 round and it won't go off.
