Identifying Hazards
Inspect the jobsite before transporting equipment; check for the following:
• Overall grade or slope
• Changes in elevation such as hills or open trenches
• Obstacles such as buildings, railroad crossings, or streams
• Signs of utilities
– “Buried utility” notices
– Gas or water meters
– Drop boxes
– Manhole covers
– Utility facilities without overhead lines
– Junction boxes
– Light poles
– Sunken ground
• Traffic
• Access
• Soil type and condition
• Loose material such as fencing or cable
Locating Utilities
1. Notify One-Call Services; mark the proposed path with white paint and have the
underground utilities located before working.
• In the US or Canada, call 811 (US) or 888-258-0808 (US and Canada). Also contact
any local utilities that do not participate in One-Call service.
• In countries that do not have a One-Call service, contact all local utility companies to
have underground utilities located.
2. Verify underground utilities; have an experienced locating equipment operator sweep
the area within 6 m (20 ft) to each side of the proposed excavation to verify previously
marked line and cable locations. Mark the location of all buried utilities and obstructions.
3. Locate overhead lines; note the location and height of all overhead lines in the jobsite
and ensure that the equipment maintains a proper distance from live lines.
