Even then, you can only work with it in teams of at least 2, all being certified to work with HF, only during normal business hours, and with a safety checklist a mile long, which includes checking to see that the calcium gluconate in the emergency kit is unopened and unexpired, and there are extra gloves with it, so the person applying it to you does not also get poisoned just by touching you.
That reminds me of why I decided against buying a portable sawmill. The nice ones come with an amputation kit, so when you cut something off accidentally there's a tourniquet on hand to slow the bleeding.
