I used to carry a Johnson & Johnson first-aid kit, which came in a 5"x8" plastic box. It followed me from car to car for years and was never used. Until one day…
I was working on a student film called The A Train. A little Greek girl wants to leave Greece (where her family was from and to where they returned) to her native New York. She builds a little boat. The cinematographer was on the beach getting ready for the shot, and the boat was near the water. The tide was coming in and it took the boat. The cinematographer went into the surf to get it. A wave picked up the boat and drove it into his shin, taking off some skin. Ooh, that looked painful! My little J&J kit was the only first-aid kit available, and I went to get it. I used most of the kit treating the injury. (But did I get a screen credit as “medic”? No! I didn’t even get credit for the chalkboard drawing that opened the film. No, I was listed as “Grip”.)
The little kit I’d bought so long ago at Thrifty’s (now Rite-Aid, FWIW) was good enough for this one incident; but I wanted to be better prepared for the next time. I keep the REI kit attached to my “ditty bag” (a circular bag for my slate, light meter, and various other filmmaking tools). When I got the Jeep, I bought a duplicate kit to carry in there. Although I have used my “filmmaking” first-aid kit around the house, mostly for the bandages, which I’d added more of, the ibuprofen for the co-worker is the first time I’ve used the one in the car. Better to have it and not need it than to need it and not have it!
So what’s in the first aid kit you carry in your car?
