Safety Alert Classifications

These classifications and the icons defined on the following pages work together to alert you to situations which could be harmful to you, jobsite bystanders or your equipment. When you see these words and icons in the book or on the machine, carefully read and follow all instructions. YOUR SAFETY IS AT STAKE.

Watch for the three safety alert levels: DANGER, WARNING and CAUTION. Learn what each level means.

indicates an 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 result in minor or

moderate injury.

Watch for two other words: NOTICE and IMPORTANT. NOTICE can keep you from doing something that might damage the machine or someone's property. It

can also alert you against unsafe practices.

IMPORTANT can help you do a better job or make your job easier in some way.

Emergency Procedures

Before operating any equipment, review emergency procedures and check that all safety precautions have been taken.

EMERGENCY SHUTDOWN - Turn ignition switch to STOP.

Electric Strike Description

When working near electric cables, remember the following:

• Electricity follows all paths to ground, not just path of least resistance.

• Pipes, hoses, and cables will conduct electricity back to all equipment.

• Low voltage current can injure or kill. Almost one-third of work-related electrocutions result from contact with less than 440 volts.

Most electric strikes are not noticeable, but indications of a strike include:

• power outage

• smoke

• explosion

• popping noises

• arcing electricity

If any of these occur, assume an electric strike has occurred.
