Holy shit guys...stop pouring piss and flour and sugar and axle grease into open wounds. You have phones and cars, a hospital or urgent care can't be that far away. Come on now.
Re: the Quikclot, it's a different brand and product from Celox. The powder version is falling out of style in the EMS world, as I understand it, compared to the impregnated-bandage version. The former can get pushed out by arterial blood, and doesn't apply compression inside the wound. It's also much harder for doctors to clean out once you do get help. I keep some in my first aid kit but generally it's meant for catastrophic bleeding. If a wound warrants the Celox coming out, an ER trip is a given. Otherwise it's not really necessary.
Also recommend exploring some of the fancier medical tapes and wound dressings from 3M and other medical suppliers. Tegaderm, Blenderm, and Micropore are all fantastic when you need a bandage or some such to stay on. Nexcare are the best bandages hands down. Alcohol wipes to ensure bandages stick. Steri-strips are probably a better bet for wound closures than DIY glue/thread jobs. Or Vetbond which is the same thing as medical superglue for humans, only you can actually buy it.
Splinter-Outs are cheap (and sterile) and do their job well. I keep hydrocolloid and padded silicone dressings in my kit and around the house as well. They come in handy a couple times a year.
First aid or antiseptic gel with lidocaine can be a godsend for abrasions and burns, along with occlusive dressings like Xeroform.
Get an Israeli bandage. Actually get two, and learn with the other one so you know how and when to use it.
If you carry a gun or any of your employees are likely to, get a HALO chest seal and learn how to use it.
Lots of other options but unless you're really in the middle of nowhere these kits are good for minor injuries and for keeping people alive/comfortable until they can get to an ER. Don't try to play doctor too hard.
I put my own kit together because I wasn't thrilled with the quality of any pre-packaged first aid kits I've seen. Most have the cheapest possible version of each item. But if you don't want to spend a couple nights browsing Amazon, just get a good approved kit.
If your shop is a business involving other people, get an AED as well. Aspirin is great but it'll only go so far. If you're worried about falling down and not being able to reach a phone, considering an Apple watch if you already use an iPhone. They can detect falls and automatically alert EMS.
Most importantly though: stay safe. Don't poke around live machinery when you're tired.
