We know you've been planning to put a first-aid kit in your car - but you just never got around to it, did you?
Will a first-aid kit stop the bleeding from a slashed aorta? Nope. But you should have a basic first-aid kit on hand, so when you bash your knuckles after using your vise-grips, you'll be all set. A good first-aid kit should include a selection of bandages, a few sterile gauze pads and dressings, some antibiotic ointment, acetaminophen tablets and a pair of nitrile protective gloves.
Tip: It's often less expensive to buy these items individually at a drug store than to purchase a fancy, pre-packaged kit.
Mylar Space Blanket
Will our Mylar space blanket save you at 40 below in blizzard-force winds? Of course not! A good space blanket, however, will reflect back a lot of your heat--they're used by rescuers of all sorts. Having one in your car might just help keep you keep cozy when you're broken down next January in East Moosejaw.
Having a few clean rags on hand is a great idea. They'll be there when you need them to absorb fluids of all kinds, whether oil, gas, coffee, spittle, blood or cerebral-spinal fluid. Then again, if you're mopping up cerebral-spinal fluid, you have bigger problems on your hands than getting a stain on your shirt.
Tip: Double the number of rags you think you'll need. Then add a few more.
Gojo Hand Cleaner
