A tower climber [1] specializes in maintenance, installation, and decommissioning of cellular and radio tower components such as coaxial cable, antennas, radios, fiber-optic cable and broadcast equipment for cell phones, television, radio, etc.
Tower climbers perform routine inspections and tests on broadcasting towers, and may also be called upon to perform repairs and to provide input when plans for new equipment are being developed.
Along with the installers of the tower antennas, other crews climb the towers to perform condition checks of the towers, guy lines and lighting systems. One of the most demanding aspects of many tower climber jobs is hauling materials and tools up to the proper installation height on the tower. In most cases, the climber scales the tower to the desired height and lowers a rope to a ground crew member who then ties it to a needed part on the ground. The tower worker then pulls the piece up and secures the rope before installing the part onto the tower.
Tower climbers may be injured or killed by falling objects, structural collapses and equipment failures. Some of the more frequently encountered hazards include falls from great heights; electrical hazards; hazards associated with hoisting personnel and equipment with base-mounted drum hoists; inclement weather; and structural collapse of towers.

Working on cellphone towers is the deadliest job in the United States, according to a trade publication, [3] and it has been claimed that the tower climbing industry experiences 10 times more death casualties than the construction workers. [4] There were 50 - 100 deaths from falls from communication towers between 2003 and 2011. [5] The head of the Occupational Safety and Health Administration (OSHA) once called tower climbing “the most dangerous job in America.” [6]
Climbing is the activity of using one's hands, feet, or other parts of the body to ascend a steep topographical object that can range from the world's tallest mountains to small boulders. Climbing is done for locomotion, sporting recreation, for competition, and is also done in trades that rely on ascension, such as rescue and military operations. Climbing is done indoors and outdoors, on natural surfaces, and on artificial surfaces
The Occupational Safety and Health Administration is a regulatory agency of the United States Department of Labor that originally had federal visitorial powers to inspect and examine workplaces. The United States Congress established the agency under the Occupational Safety and Health Act, which President Richard M. Nixon signed into law on December 29, 1970. OSHA's mission is to "assure safe and healthy working conditions for working men and women by setting and enforcing standards and by providing training, outreach, education, and assistance." The agency is also charged with enforcing a variety of whistleblower statutes and regulations. OSHA's workplace safety inspections have been shown to reduce injury rates and injury costs without adverse effects on employment, sales, credit ratings, or firm survival.
A work accident, workplace accident, occupational accident, or accident at work is a "discrete occurrence in the course of work" leading to physical or mental occupational injury. According to the International Labour Organization (ILO), more than 337 million accidents happen on the job each year, resulting, together with occupational diseases, in more than 2.3 million deaths annually.
Tallinn TV Tower is a free-standing structure with an observation deck, built to provide better telecommunication services for the 1980 Moscow Summer Olympics regatta event. It is located near the suburb Pirita, six km north-east of the Tallinn city center. With its 313 m (1030.2 ft), the TV tower is the tallest nonbuilding structure in Tallinn. The tower was officially opened on 11 July 1980. The viewing platform at a height of 170 metres was open to the public until 26 November 2007, when it was closed for renovation. The tower began receiving visitors again on 5 April 2012. The building is administered by the public company Levira and is a member of the World Federation of Great Towers.
Construction site safety is an aspect of construction-related activities concerned with protecting construction site workers and others from death, injury, disease or other health-related risks. Construction is an often hazardous, predominantly land-based activity where site workers may be exposed to various risks, some of which remain unrecognized. Site risks can include working at height, moving machinery and materials, power tools and electrical equipment, hazardous substances, plus the effects of excessive noise, dust and vibration. The leading causes of construction site fatalities are falls, electrocutions, crush injuries, and caught-between injuries.
A confined space is a space with limited entry and egress and not suitable for human inhabitants. An example is the interior of a storage tank, occasionally entered by maintenance workers but not intended for human occupancy. Hazards in a confined space often include harmful dust or gases, asphyxiation, submersion in liquids or free-flowing granular solids, electrocution, or entrapment.
The Senior Road Tower is a guyed mast for FM and TV broadcasting, measuring 1,971 feet (601 m) tall, located in unincorporated northeastern Fort Bend County near Missouri City, Texas, United States.
Radio masts and towers are typically tall structures designed to support antennas for telecommunications and broadcasting, including television. There are two main types: guyed and self-supporting structures. They are among the tallest human-made structures. Masts are often named after the broadcasting organizations that originally built them or currently use them.
A fly system, or theatrical rigging system, is a system of ropes, pulleys, counterweights and related devices within a theater that enables a stage crew to fly (hoist) quickly, quietly and safely components such as curtains, lights, scenery, stage effects and, sometimes, people. Systems are typically designed to fly components between clear view of the audience and out of view, into the large space, the fly loft, above the stage.
A safety harness is a form of protective equipment designed to safeguard the user from injury or death from falling. The core item of a fall arrest system, the harness is usually fabricated from rope, braided wire cable, or synthetic webbing. It is attached securely to a stationary object directly by a locking device or indirectly via a rope, cable, or webbing and one or more locking devices. Some safety harnesses are used in combination with a shock-absorbing lanyard, which is used to regulate deceleration and thereby prevent a serious G-force injury when the end of the rope is reached.
A hoist is a device used for lifting or lowering a load by means of a drum or lift-wheel around which rope or chain wraps. It may be manually operated, electrically or pneumatically driven and may use chain, fiber or wire rope as its lifting medium. The most familiar form is an elevator, the car of which is raised and lowered by a hoist mechanism. Most hoists couple to their loads using a lifting hook. Today, there are a few governing bodies for the North American overhead hoist industry which include the Hoist Manufactures Institute, ASME, and the Occupational Safety and Health Administration. HMI is a product counsel of the Material Handling Industry of America consisting of hoist manufacturers promoting safe use of their products.
A roofer, roof mechanic, or roofing contractor is a tradesperson who specializes in roof construction. Roofers replace, repair, and install the roofs of buildings, using a variety of materials, including shingles, bitumen, and metal. Roofing work includes the hoisting, storage, application, and removal of roofing materials and equipment, including related insulation, sheet metal, vapor barrier work, and green technologies rooftop jobs such as vegetative roofs, rainwater harvesting systems, and photovoltaic products, such as solar shingles and solar tiles.
Fall arrest is the form of fall protection which involves the safe stopping of a person already falling. It is one of several forms of fall protection, forms which also include fall guarding and fall restraint.
Potable water diving is diving inside a tank that is used for potable water. This is usually done for inspection and cleaning tasks. A person who is trained to do this work may be described as a potable water diver. The risks to the diver associated with potable water diving are related to the access, confined spaces and outlets for the water. The risk of contamination of the water is managed by isolating the diver in a clean dry-suit and helmet or full-face mask which are decontaminated before the dive.
The Willow Island disaster was the collapse of a cooling tower under construction at the Pleasants Power Station at Willow Island, West Virginia, on April 27, 1978. 51 construction workers were killed. It is thought to be the deadliest construction accident in U.S. history.
Fall protection is the use of controls designed to protect personnel from falling or in the event they do fall, to stop them without causing severe injury. Typically, fall protection is implemented when working at height, but may be relevant when working near any edge, such as near a pit or hole, or performing work on a steep surface. Many of these incidents are preventable when proper precautions are taken, making fall protection training not only critical, but also required for all construction workers. Fall Protection for Construction identifies common hazards and explains important safety practices to help ensure every team member is prepared to recognize fall hazards on the job and understand how to keep themselves and others safe.
Mobile cell sites are infrastructures transportable on trucks, allowing fast and easy installation in restricted spaces. Their use is strategic for the rapid expansion of cellular networks putting into service point-to-point radio connections as well as supporting sudden increases in mobile traffic in the case of extraordinary events. Mobile cell sites are also used by law enforcement organizations to gather intelligence. Mobile cell sites require neither civil works nor foundations, just minimal requirements like commercial power and grounding. The mobile units have been designed to be a temporary solution, but if requested, they can be transformed into permanent stations.
There are a number of occupational hazards of grain facilities. These hazards can be mitigated through diligence and following proper safety procedures. Grain Facility Occupation Exposure is the quantifiable expression of workplace health and safety hazards a grain-handling facility employee is vulnerable to in performing their assigned duties. Exposure represents the probability that a given hazard will have some level of effect of a receptor of interest. This page utilizes data and information regarding grain facility occupational exposure in the United States.
Rigging is both a noun, the equipment, and verb, the action of designing and installing the equipment, in the preparation to move objects. A team of riggers design and install the lifting or rolling equipment needed to raise, roll, slide or lift objects such as heavy machinery, structural components, building materials, or large-scale fixtures with a crane, hoist or block and tackle.
The introduction and rapid expansion of solar technology has brought with it a number of occupational hazards for workers responsible for panel installation. Guidelines for safe solar panel installation exist, however the injuries related to panel installation are poorly quantified.
