machine, use signal words to identify

the following:

Safety alert symbol—used to

alert personnel to potential

personal injury hazards. Obey

all safety messages that follow

this symbol to avoid possible

injury or death.

Indicates a imminently

hazardous situation which, if

not avoided, will result in death

or serious injury.

Indicates a potentially

hazardous situation which, if

not avoided, could result in

death or serious injury.

Indicates a potentially

hazardous situation which, if

not avoided, may cause minor

or moderate injury.

Indicates a potentially

hazardous situation which, if

not avoided, may result in

property damage.

Be sure to wear protective eye wear

and other protective clothing if the

situation warrants it.

hazards such as moving parts, free

swinging or unsecured components

when lifting or placing loads. Always

wear approved steel-toed shoes.

Workplace Safety

Any person working on or around a machine

must be aware of all known safety hazards.

Personal safety and the continued safe

operation of the machine should be your top

priority.

Be sure to keep sparks, flames and

lighted tobacco away from flammable

gases and engine fuels. Always have

an approved fire extinguisher within

easy reach.

Be sure that all tools and working

areas are properly maintained and

ready for use. Keep work surfaces

other lifting or supporting device is

fully capable of supporting and

stabilizing the weight to be lifted. Use

only chains or straps that are in good

condition and of ample capacity.

Be sure that fasteners intended for
