•Wear the appropriate personal protective equipment for the task.
•When working on or around all equipment, avoid wearing loose clothing, jewelry, unrestrained long hair,
loose ties, belts, scarves, or articles that may be caught in moving parts. Keep all extremities away from
moving parts. Entanglement can cause death or severe injury.
•For new equipment, check input voltage and compare with the equipment voltage rating. DO NOT supply
the incorrect power to any equipment for any reason whatsoever. Electrical specifications for your
machine are printed on the machine tag. A properly grounded receptacle is required for safe operation
regardless of voltage requirements.
•Use this equipment only for its intended purpose.
•Keep the equipment operating zone free of obstacles that could cause a person to trip or fall toward an
operating machine. Keep fingers, hands, or any part of the body out of the machine and away from
moving parts when the machine is operating.
•Any machine with moving parts and/or electrical components can be potentially dangerous no matter
how many safety features it contains. Stay alert and think clearly while operating or servicing the
equipment. Be aware of operations and personnel in your surroundings. Be attentive to indicator lights,
warning lights, and/or operator interface screens displayed on the machine and know how to respond.
•Do not operate machinery if you are fatigued, emotionally distressed, or under the influence of drugs or
alcohol.
•Know where the FIRST AID SAFETY STATION is located.
•Know where the FIRE EXTINGUISHING EQUIPMENT is located.
•Never sit or stand on the machine or on anything that might cause you to fall against the machine.
•Rotating and moving parts are dangerous. Keep clear of the operating area. Never put any foreign object
into the operating area.
•Use proper lifting and transporting devices for heavy equipment. Some types of equipment can be
extremely heavy. An appropriate lifting device should be used.
•Use caution when moving portable equipment. In some cases, the machinery can be heavy and/or may be
top heavy. Portable equipment can gain momentum during transporting and must always be controlled.
