I see IFAK's, Blow-Out Kits, etc.. not just here, but all over the internet and just want to offer a cautionary note to all who carry these things. First of all, thank you for all you do. It takes a special person to step up and make the effort and in this day and age, we have plenty who will stand by and allow a person, even children to die rather than be bothered taking the time and inconvenience to attempt to save a life. There are some things to consider when putting together a kit. Those that know will nod and smile, others might get miffed, but that's not the intent and as they say. don't try on the shoe if you're afraid it'll fit! I see a lot of gear Carried/employed in kits by people who admit to having no training in it's use other than reading about it on the internet, or watching somebody's youtube video. Again; hats off to any lay person who actually jumps in and does something helpful, but it's not the actual skill involved in performing the intervention where I see people f@#k up, its the on-going monitoring of said interventions that people have no clue about. Reassessment, because chest seals aren't infallible; I don't even use vented seals because they are just as likely to clog as work. I get seizures when I see chest darts in a lay person's kit who has admitted to not having trained been to a minimum competency level (READ: Licensed to practice). Think about this: Too high and you stick a large vessel and create non-compressible bleeding. Too low and at the least, you create a pneumo where none previously existed (I've seen this done by trained "professionals"). At the worst, you can nick a coronary vessel and create pericardial tamponade. An injury that requires a pericardiocentesis is risky enough in the hospital under ideal conditions, let alone as a field-expedient procedure! The best you can do is the basics. Bleeding control and BLS airway and breathing care. As long as you stick to solid, simple basics, the Good Samaritan laws of the country will absolutely protect you. Step out of your depth and prepare to lose the shirt off your back. If you do live in the boonies, or venture into areas where injuries are common, you owe it to yourself and the people you could potential save (or kill) to get accredited training from a reputable local institution of higher learning. Most people do this by volunteering at their local Fire Department (And they need your time!). Most departments will pay for as much training as you seek to get as long as you use your skills to run fire and EMS calls. My intent is in no way meant to discourage anybody from getting out and helping people in the worst moments of their life; if some clarity comes about, so be it. I want people to be doing the best they can at the highest level they seek to practice. Cheers, peace and party on!
