ASSH LAWNMOWER SAFETY
Keep Your Hands Safe: Follow Lawnmower Safety Tips
Each 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 would like to provide you with patient information to help you avoid these injuries.
Kinetics of Rotary Power LawnmowersKinetic 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.
Injury Profile
Adults 25-64 years
Children under age five
22% involve wrist, hand or finger
14% involve foot, ankle or toes
25% of all hand and foot injuries result in amputation
Deaths occurred in children under six years of age
Common Injury Patterns

Common Injury Patterns
- Direct contact with rotating or jammed blade
- Serious avulsion (tearing/separating) injuries to soft tissue and bones
- Gross contamination from contact with grass and soil harboring pathogens
- Injuries requiring multiple staged surgeries to cleanse wounds and provide soft tissue coverage (to regenerate healthy tissue/skin)
- Wet grass
- Damp ground
- Passengers (adult/child) on riding mowers or in cart towed behind mower
- Mower being pulled backward
- Sloping lawn mowed by power mower up and down slope, instead of across
- Sloping lawn mowed by riding mower across slope, instead of up and down
- Wearing sandals or open-toed shoes
- Operator attempts to unclog blades with hand or foot
Remember the following:
- Read your mower's instruction manual prior to use.
- DO NOT REMOVE safety devices or guards on switches.
- NEVER insert hands or feet into the mower to remove grass or debris. Even with the motor turned off, the blade remains engaged.
- ALWAYS use a stick or broom handle to remove any obstruction.
- NEVER cut grass when it is wet or when the ground is damp.
- NEVER allow a child to operate the mower at any time or be in the area to be mowed.
- NEVER allow passengers, other than the operator, on riding mowers.
- Keep your mower in good working order with sharp blades.
- DO NOT DRINK before or while using your lawnmower.
- Wear protective boots, goggles, gloves and long pants.
- Do not operate the lawnmower while barefoot.
- Be cautious when mowing hills or slopes.

2008 AAOS Position Statement taken from AAOS website by www.handctr.com
Power Lawnmower Safety.
This Position Statement was developed as an educational tool based on the opinion of the authors. It is not a product
of a systematic review. Readers are encouraged to consider the information presented and reach their own
conclusions.
More than 210,000 people – including approximately 16,000 children - were treated in doctors’ offices, clinics and
emergency rooms for lawnmower-related injuries in 2007, according to the U.S. Consumer Product Safety
Commission. Lawnmower injuries often result in partial or complete amputation of both lower and upper extremities.
The American Academy of Orthopaedic Surgeons believes that the great majority of these injuries are
preventable. The Academy recommends the following safety guidelines when using lawnmower
equipment.
Never let children operate lawnmowers. Keep kids 15 years of age and younger away when lawnmowers are in use.
Children should not be in the yard while the lawn is being mowed.
No riders other than the operator, regardless of age, should be allowed on a riding mower.
Be sure the motor has been turned off before inspecting or repairing power lawnmower equipment.
Do not tamper with safety release switches.
Keep lawnmowers in good working order with sharp blades.
Remove stones, toys and other objects from the lawn before you start mowing.
Wear protective gloves, goggles, boots and long pants when you use lawnmowers. Never mow barefoot or in
sandals.
Use caution when mowing hills and slopes. Mow across with a push mower; mow up and down with a riding
mower. Do not cut wet grass.
Be sure the motor is off before inspecting or repairing lawnmower equipment.
Read the instruction manual before using a lawnmower.
Be sober (i.e., don’t drink and mow.)
Do not remove safety devices, shield or guards on switches, and keep hands and feet away from moving parts.
Stay away from the engine cowling, as it can become very hot and burn unprotected flesh.
Add fuel before starting the engine, not when it is running or hot.
Use a stick or broom handle (not your hands or feet) to remove debris in lawnmowers or snowblowers.
Do not leave a lawnmower unattended when it is running. If you must walk away from the machine, shut off the
engine.
