My wife keeps an emergency bag current and ready to go out the door. Medical supplies that include MORE than band aids..i.e.. splints,wraps,pain killer,blankets,water,etc. In an emergency of large magnitude you should be prepared to help someone who fell and has a gaping wound.
There is a relatively new product that all EMTs carry that absolutely stops arterial bleeding called Quick Clot. It is not cheap but I wouldn't be with out it. PLEASE,all of you, get some and keep one in your shop!!!! The need to stop arterial bleeding could come up in anybody's shop.I believe this product was just recently developed during the Gulf War.
