1.2 Safety Precautions
This manual contains basic advice for the installation and operation of Metrotech Utility Line
Locators and accessories. The manufacturer is not liable for damage to material or humans
due to non-observance of the instructions and safety advice provided in this manual.
Therefore, this manual should be provided and reviewed by all personnel associated with the
line locating equipment.
Familiarize yourself with all required safety practices of the local utility company,
or other owner of the plant before entering an access area, or connecting a
Metrotech transmitter.
Ensure that the line is de-energized and out of service, before connecting the
transmitter directly to any conductor. NEVER make a direct connection to a live
power cable.
Follow the appropriate safety procedures to avoid the risk of injury if using a
clamp on energized electrical or control lines.
Observed
Safety
Practices
Pay special attention when using a locator in high traffic areas.
Intended
application
Safe operation is only realized when using the equipment for its intended
purpose. Using the equipment for other purposes may lead to human danger
and equipment damage.
The limits described under the technical data section may not be exceeded.
Malfunctioning
Behavior
The equipment may only be used when working properly. When irregularities or
malfunctions appear that cannot be solved consulting this manual, the
equipment must immediately be put out of operation and marked as not
functional. Metrotech Coporation must be contacted for technical support and/or
service. The instrument may only be operated when the malfunction is resolved.
Fire safety rules
The five safety rules must always be followed when working with High Voltage (HV):
De-energize
Protect against re-energizing
Confirm absence of voltage
Ground and short-circuit
Cover up or bar-off neighboring energized parts
Fire fighting in electrical installations:
Recommended extinguishing agent: carbon dioxide (CO
2
)
Carbon dioxide is electrically non conductive and does not leave residue. It is safe
to use in energized facilities as long as the minimum distances are observed.
It is essential to observe the safety instruction on the extinguishing agent.
Dangers when operating with HV:
Special safety attention is needed when operating HV facilities, especially non-
stationary equipment. The regulations VDE 0104 about setting up and operation of
electric test equipment, i.e. the corresponding EN 50191 as well as country-specific
regulations and standards must be observed.
Safety installations may not be by-passed nor deactivated.
Operation requires a minimum two people whereas the second person must be
able to activate the emergency switch in case of danger.
To avoid hazardous electric charges of metallic parts in the vicinity, all metallic
parts must be grounded.
To avoid drawing dangerous arcs, switching should only be done in a de-energized
condition.
The equipment and all accessories must be connected according to applicable
standards VDE, EN or DIN as well as country-specific regulations.
