Tree stand safety: not concerned? Crunch the numbers. (THE HUNT DOCTORS[TM].

TREE STAND SAFETY is deadly serious. Other than death, falls can have other horrible outcomes: closed head injuries; fractures to the skull, spine and extremities; lacerations; tears to about any ligament, tendon or muscle; and internal injuries.

You don't really need to be twenty feet up to sustain serious injuries. Twelve feet is plenty, depending on how you land.

With your safety at risk, why trust anything less then an industry-approved stand? They're widely available in all price ranges. Don't trust home-made stands; bro ken necks, crushed heels and dislocated limbs are just not worth the few dollars (if any) we save in building our own stands.

You need more than a safe tree stand to protect you. Never hunt without a certified safety harness.

If you're on an outfitted hunt, don't depend on what is going to be provided. Bring your own safety equipment with you.

If you still don't think it will happen to you, consider the accompanying research findings. Using physics equations and complicated calculations, these numbers will give you some idea of the force and energy with which you would hit the ground. These eye-opening numbers clearly show why serious injuries result from what is thought to be relatively short falls.

Obviously, what you fall onto has an impact on the degree of injury sustained as well. But you won't fall if you use quality gear.

HERE'S HOW YOU HIT THE GROUND

* 1 Pound = 454 grams

* 1 Gram = 15.432 grains

* 1 Meter = 3.28 feet

* Energy (ft-lbs)= weight (grs) x velocity squared (fps) / 450395 (constant)

* Free fall = 9.8 m/sec squared

* Velocity final = initial velocity (zero for us) + (free fall [9.8 m/sec] squared) x time (sec)

* Distance fallen = 1/2 free fall (9.8) x time squared (seconds)

A 150-lb person falling 12 feet produces 1,797 ft-lbs of energy (near .30-30 muzzle energy); falling 20 feet produces 2,994 ft-lbs (near .30-06 muzzle energy).

A 200-lb person falling 12 feet produces 2,397 ft-lbs (.4570 muzzle energy); falling 20 feet produces 3,993 ft-lbs. (.338 Win. Mag. muzzle energy).
