Dress appropriately for the task. Wear long pants, long-sleeved shirts (to avoid injuries from thrown objects like rocks or sticks), close-fitting clothes and no jewelry (to avoid getting anything caught in moving parts), sturdy shoes with slip-resistant rubber soles, eye protection, heavy gloves (protects hands when changing, sharpening, or cleaning blades), and hearing protection such as ear plugs when using motor-driven equipment.
Before starting up machinery, remove objects from the area in which you are working that can cause injury or damage equipment, such as sticks, glass, metal, wire, and stones.
Be sure you know how to operate the equipment. Know where the controls are and what they do. Make sure the equipment is in proper operating condition and guards or other safety devices have not been removed or disabled.
Make sure that safety devices on the equipment are in place and functioning properly before starting work.
Teenagers should only be allowed to operate outdoor power equipment if they possess adequate strength and maturity to do so safely. They also should be supervised by a responsible adult.
Keep children indoors and supervised at all times when any outdoor power equipment is being used. Young children move quickly and are attracted to mowers and mowing activity, especially if they have been given rides on mowers before.
Never assume children will remain where you last saw them. Be alert and turn off the mower if children enter the mowing area. Use extra care when backing up or when approaching corners, shrubs, and trees.
Unplug electric tools and disconnect spark plug wires on gasoline-powered tools before making adjustments or clearing jams near moving parts.
Be sure power tools are turned off and made inoperable if they must be left unattended to prevent use by children.
Handle gas carefully. Never fill gasoline tanks while machinery is on or when equipment is still hot. Wipe up spills. Store gas in an approved container away from the house. Finally, never smoke or use any type of flame around gasoline or any gasoline-powered equipment.
Never work with electric power tools in wet or damp conditions. For protection against electrocution, use a ground fault circuit interrupter (GFCI). GFCIs come in several models, including a portable plug-in type.
Be sure that extension cords are in good condition, are rated for outdoor use, and are the proper guage for the electrical current capacity of the tool.
