Safety

• Locators are precision well engineered tools, however the
• environment we locate in is not perfect.

• Always be aware of the influence of distorted fields
• Always take account of visual clues (manholes, pedestals etc.)
• Always use “as built plans” if available

•

Never

use digging machinery over marked out pipes or cables

•

Do not

give “depth” information unless authorized by your company

• Follow all Federal, State, and company rules and regulations particularly as regards

safety

• Dispose of Batteries in line with Federal, State or company regulations
• Never submit batteries to extreme heat or fire.

Call before you dig - Always dig carefully
