Safety 

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, 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 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.
