The jumping power of a human being cannot cancel out the falling velocity of the elevator; the elevator car would have struck the bottom of the shaft at around 53 mph (85 km/h), while a human being can jump only at around 2 or 3 mph (3 or 5 km/h), not enough to make a significant difference in the impact force.
A person can sense electric current as low as 1 mA for 60 Hz AC and as low as 5 mA for DC. At around 10 mA, AC current passing through the arm of a 68-kilogram (150 lb) human can cause powerful muscle contractions; the victim is unable to voluntarily control muscles and cannot release an electrified object.

The first type is more common as pressure reduction from normal atmospheric pressure to a vacuum can be found in both space exploration and high-altitude aviation. Research and experience have shown that while exposure to a vacuum causes swelling, human skin is tough enough to withstand the drop of one atmosphere .
Human skin does not need to be protected from vacuum and is gas-tight by itself. Human flesh expands to about twice its size in such conditions, giving the visual effect of a body builder rather than an overfilled balloon. This can be counteracted through mechanical counter-pressure from a suitably designed garment.
