Emergency Procedures

Jobsite hazards could cause death or serious injury. Use correct equipment and work methods. Use and maintain proper safety equipment.

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

EMERGENCY SHUTDOWN - Turn ignition switch to stop position or push remote engine stop button (if

Electric Strike Description

Electric shock. Contacting electric lines will cause death or serious injury.

Know location of lines and stay away.

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. Many 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.
