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.

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).

7

• 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

CUSTOMER ASSUMES ALL RISK FROM ANY INJURY RESULTING

FROM IMPROPER INSTALLATION, USE, OR MAINTENANCE OF

TRIPODS, TOWERS, OR ATTACHMENTS TO TRIPODS AND TOWERS

SUCH AS SENSORS, CROSSARMS, ENCLOSURES, ANTENNAS, ETC.
