This is my car FAK, one of a few for different purposes:
These are the contents of the top compartment:
Top row: Bulb aspirator, oral airways, pocket mask, suction device, marker pen, center punch, trauma shears.
Midle row: Gloves, ace wrap, ammonia inhalants, alcohol gel, bandaids, mylar blanket, roller gauze.
Bottom row: Cederoth bloodstoppers, triangular bandages, alcohol wipes, tapes.
These are the contents of the lower compartment:
Top row: Burn sheet, infection control kit.
Middle row: Adhesive triage tags, paramedic cheat book, gowns and masks, BP cuff and stethoscope, Asherman chest seal, Sam splint, more gloves.
Bottom row: Vaseline gauze, emesis bag, trauma dressings, abdominal pads (mid-size dressings), bulk 4x4s, plastic blanket.
The case is just a cheap plastic file box from the discount rack at an office supply store, but it's rigid and waterproof, so it fits my needs. Most things are vacuum packed. This is not a disaster/EOTWAWKI kit. It is just a small kit I keep in the car. After 30 years as a paramedic, I have a decent fix on what I really want and need, and know how to improvise. But I am, as ever, open to suggestions, comment and criticisms, and I invite yours.
