Well, I certainly don't have 20+ years as a timber manager (I am curious what YEARS these were), but I do have 46+ years in EMS, 40+ years as a career Paramedic doing 911, Flight/Critical Care, and TEMS, as a State and Nationally Registered Paramedic, a Flight Paramedic (FP-C), a Critical Care Paramedic (CCP-C), and a Tactical Medic (TEMS/SWAT Medic)
So I'm sorry to inform you but no, Snake Bite kits are no longer recommended (they may have been when your father was a timber manager), and have NOT been recommended for many years
I provided you a few links, with further information
Do with the information as you wish, I am just giving you the FACTS
What you do with those FACTS is up to you
