Operating/Maintenance Safety:
When operating this machine, the safety of the operating crew and other workers in the vicinity
must be the principal concern. All persons operating this machine must understand the necessary
safety precautions to help minimize the risk of accidents and injury. The operator must ensure that
all fire fighting equipment is in working order, inspect the condition of all walkways, handrails,
ladders, and guards.
Personal Protection Equipment:
All safety equipment such as hardhat, steel cap boots, safety goggles, hearing protection, gloves,
etc., should be worn while operating this Machine.
Snug fitting clothing should be worn by the operator in or around the drill so as not to be caught
up in any moving machinery.
All safety equipment such as hardhat, steel cap boots, safety goggles, hearing protection, gloves,
etc., should be worn while operating this Machine.
Snug fitting clothing should be worn by the operator in or around the drill so as not to be caught
up in any moving machinery.
Overhead and Buried Utilities:
Special precautions must be taken by everyone when using a drill rig in the vicinity of electrical
power lines and other utilities. Underground electricity is as dangerous as overhead electricity.
Be aware and always suspect the existence of underground utilities such as electrical power, gas,
petroleum, telephone, sewer, and water.
Electricity can shock, burn and cause death.
• Overhead and buried utilities should be located, noted and emphasized on all boring
location plans and boring assignment sheets.
• When overhead electrical power lines exist at or near a drilling site or project,
consider all wires to be live and dangerous.
• Watch for sagging power lines before entering a site. Do not lift power lines to
gain entrance.
• Before raising the drill rig mast on a site in the vicinity of power lines, walk
completely around the drill rig. Determine what the minimum distance from any point on the drill
rig to the nearest power line will be when the mast is raised and/or being raised. Do not raise the
mast or operate the drill rig within a minimum of three (3) meters of any electrical power line or
other obstruction.
• Only move the drill rig with the mast down.
If there are any questions concerning the safety of drilling on sites in the vicinity of overhead
power ll your supervisor.
