There are two limitations of this technology. One is that all non-metallic pipes to be traced must be available

for connection directly to the transmitter. The second is that excessive energy imparted to the pipe may

cause damage to the pipe.

2.7 - Training Workers for Borehole Clearing Tasks

The following are considered to be minimum levels of training for individuals performing the tasks

associated with clearing a borehole:

• 40-Hour OSHA HAZWOPER training (required for HAZWOPER sites).

• Some level of internal training and prior drilling experience regarding safe locations in which to drill.

Specific drilling tasks may require more experience and training for the:

• Individual who makes the decision that the location is acceptable to drill,

• Quality Assurance (QA) Point Person.

A senior-level project team member should consult with the field personnel during the final location of the

borehole.
