4.1
Inspecting the work site for hazards
Carefully examine the structure to be drilled and surroundings for hazards before drilling.
DANGER
: Risk of electric shock, fire, or property damage
Drilling a structure may damage a dangerously live electric cable or a pressurised pipe. Before
drilling a structure, make sure the structure doesn’t contain dangerously live cables or
pressurised pipes. If their existence cannot be excluded, the whole installation containing the
structure should be de-energized and de-pressurised before drilling begins. In some cases, a
decrease in locating accuracy may move the intended drill point.
4.2
Objects that may decrease locating accuracy
ATTENTION
: Risk of locating error due to electromagnetic conditions
Large metallic objects, radio transmitters or industrial equipment may degrade locating
accuracy or may prevent locating completely. Before attempting to locate a drill hole, take care
that there are no large metallic objects at or near the intended drill hole. Large metallic objects
include radiators, sheet metal, foil, and wire mesh among other things. Shut down or move any
radio transmitters that actively transmit on the same frequency at least 10 m away from the
intended drill hole. This includes other drill point locators.
