Priority of Access
When setting up emergency equipment, it is important to make the most of the space available. If we start thinking of all the things we can carry (pistol, OC spray, knife, tourniquet/medical, extra ammo, flashlight, etc.) we need to prioritize how easy it is access we have to each piece of equipment.
In order of consequence:
If we begin to put things in order, it is important to think of the consequence of slower access. For instance, a slower draw with a firearm can be the difference in life and death during a violent attack. Slower access with medical packing gauze may be less critical.
The other way to prioritize your needs is to put priority on tools that are needed for an event that happens without warning (firearm, knife, medical) over a tool that can be carried innocuously, giving you a readiness advantage (flashlight, OC spray).
It is simply important that you consider why your equipment is arranged. Create your own priority list and don't be afraid to question your choices.
