Precautions
DANGER — MANY HAZARDS ARE ASSOCIATED WITH INSTALLING,
USING, MAINTAINING, AND WORKING ON OR AROUND TRIPODS,
TOWERS, AND ANY ATTACHMENTS TO TRIPODS AND TOWERS SUCH
AS SENSORS, CROSSARMS, ENCLOSURES, ANTENNAS, ETC. FAILURE
TO PROPERLY AND COMPLETELY ASSEMBLE, INSTALL, OPERATE,
USE, AND MAINTAIN TRIPODS, TOWERS, AND ATTACHMENTS, AND
FAILURE TO HEED WARNINGS, INCREASES THE RISK OF DEATH,
ACCIDENT, SERIOUS INJURY, PROPERTY DAMAGE, AND PRODUCT
FAILURE. TAKE ALL REASONABLE PRECAUTIONS TO AVOID THESE
HAZARDS. CHECK WITH YOUR ORGANIZATION'S SAFETY
COORDINATOR (OR POLICY) FOR PROCEDURES AND REQUIRED
PROTECTIVE EQUIPMENT PRIOR TO PERFORMING ANY WORK.
Use tripods, towers, and attachments to tripods and towers only for purposes for
which they are designed. Do not exceed design limits. Be familiar and comply
with all instructions provided in product manuals. Manuals are available at
www.campbellsci.com or by telephoning 435-227-9000 (USA). You are
responsible for conformance with governing codes and regulations, including
safety regulations, and the integrity and location of structures or land to which
towers, tripods, and any attachments are attached. Installation sites should be
evaluated and approved by a qualified engineer. If questions or concerns arise
regarding installation, use, or maintenance of tripods, towers, attachments, or
electrical connections, consult with a licensed and qualified engineer or
electrician.
General
•Prior to performing site or installation work, obtain required approvals
and permits. Comply with all governing structure-height regulations,
such as those of the FAA in the USA.
•Use only qualified personnel for installation, use, and maintenance of
tripods and towers, and any attachments to tripods and towers. The use of
licensed and qualified contractors is highly recommended.
•Read all applicable instructions carefully and understand procedures
thoroughly before beginning work.
•Wear a hardhat and eye protection, and take other appropriate safety
precautions while working on or around tripods and towers.
•Do not climb tripods or towers at any time, and prohibit climbing by
other persons. Take reasonable precautions to secure tripod and tower
sites from trespassers.
•Use only manufacturer recommended parts, materials, and tools.

8
Utility and Electrical
•You can be killed or sustain serious bodily injury if the tripod, tower, or
attachments you are installing, constructing, using, or maintaining, or a
tool, stake, or anchor, come in contact with overhead or underground
utility lines.
•Maintain a distance of at least one-and-one-half times structure height, or
20 feet, or the distance required by applicable law, whichever is greater,
between overhead utility lines and the structure (tripod, tower,
attachments, or tools).
•Prior to performing site or installation work, inform all utility companies
and have all underground utilities marked.
•Comply with all electrical codes. Electrical equipment and related
grounding devices should be installed by a licensed and qualified
electrician.
Elevated Work and Weather
•Exercise extreme caution when performing elevated work.
•Use appropriate equipment and safety practices.
•During installation and maintenance, keep tower and tripod sites clear of
un-trained or non-essential personnel. Take precautions to prevent
elevated tools and objects from dropping.
•Do not perform any work in inclement weather, including wind, rain,
snow, lightning, etc.
Maintenance
•Periodically (at least yearly) check for wear and damage, including
corrosion, stress cracks, frayed cables, loose cable clamps, cable
tightness, etc. and take necessary corrective actions.
•Periodically (at least yearly) check electrical ground connections.
WHILE EVERY ATTEMPT IS MADE TO EMBODY THE HIGHEST
DEGREE OF SAFETY IN ALL CAMPBELL SCIENTIFIC PRODUCTS, THE
