Hand safety while lawnmowingEach year, more than 74,000 small children, adolescents and adults are injured by rotary, hand and riding power mowers due to improper handling. The American Society for Surgery of the Hand offers this information to help you avoid these injuries.

Kinetic energy (motion) imparted by a standard rotary blade is comparable to the energy generated by dropping a 21-pound weight from a height of 100 feet or is equal to three times the muzzle energy of a .357 Magnum pistol. Blade speed can eject a piece of wire or an object at speeds up to 100 miles per hour.
