Communication towers are tall structures that carry antennas for
wireless, cellular, radio, or broadcast television communications.
There are three common types of communication towers: free-standing or
lattice towers, guyed towers, and monopole towers.
Communication towers can range from 100 to over 1000 feet tall.
Increasingly, antennas are being installed on structures other than
communication towers, e.g., on water towers, on electrical and
telephone poles, and on the roofs of buildings. These alternative
structures are often used in more densely populated areas where the
construction of large communication towers is impractical or
impossible, e.g., due to zoning restrictions.
The construction and maintenance of communication towers is highly
specialized work. This work often involves workers climbing the towers
via ladders or being hoisted to workstations on the towers via base-
mounted drum hoists. To erect new towers, workers lift tower sections
or structural parts using a base-mounted drum hoist, with or without a
gin pole. Workers can also use cranes to raise tower sections. Towers
are constructed piece by piece; workers bolt each section or piece into
place before raising the next section. Non-erection construction
activities can include reinforcing the structure, upgrading antennas,
and installing new antennas on existing towers (referred to as
colocation). Workers also climb towers to perform maintenance
activities such as painting structural steel members, changing light
bulbs, and troubleshooting malfunctioning equipment. During the
performance of work activities involving communication towers, workers
are exposed to a variety of serious hazards, including fall hazards,
hazards associated with structural collapses, struck-by hazards,
hazards associated with worker fatigue, radio frequency hazards,
hazards associated with inclement weather (including extreme heat and
cold), electrical hazards, and cut and laceration hazards due to the
use of sharp, heavy tools and materials.
Work on communication towers often involves complex business
relationships among multiple companies. Many communication towers are
owned by dedicated tower companies, rather than broadcast or cell phone
companies (carriers). The tower companies then lease space on the
towers to wireless carriers. When a carrier needs to undertake a large-
scale installation or upgrade project, it will contract with a
construction management company (called a "turfing vendor"). The
turfing vendor typically hires specialized subcontractors to perform
specific elements of the project, and those subcontractors may further
contract with other companies to perform some of the work. It is not
uncommon to have as many as six or seven layers of subcontractors
between the carrier and the company that employs the workers who
actually perform the work (or certain parts of the work). This business
structure poses challenges to setting and enforcing safety rules and
ensuring the well-being of employees.
In this RFI, OSHA is seeking information about the causes of the
employee injuries and fatalities that are occurring among employees
working on communication towers. The Agency is also seeking comments on
safe work practices for communication tower activities, training and
certification practices for communication tower workers, and potential
approaches the Agency might take to address the hazards associated with
work on communication towers.
B. Hazards and Incidents
A search of OSHA's Integrated Management Information System (IMIS)
database for both fatal and non-fatal incidents involving communication
towers revealed 107 incidents from 2003 through 2013 (Docket ID OSHA-
2014-0018-01).\1\ These incidents resulted in 91 fatalities and 17
injuries. Most of the fatalities (79) were due to falls. Structural
collapses killed an additional eight people. Three fatalities involved
electrocutions, and the last fatality was due to an employee being
struck by a load while working on the tower. According to the IMIS
data, falls were also the leading cause of injuries among communication
tower workers, with 13 of 17 injuries resulting from falls (Docket ID
\1\ This data includes incidents that occurred as a direct
result of working on or with a communication tower. Incidents at
communication tower worksites resulting from unrelated factors, such
as a crane tipping over due to bad ground conditions, are not
included. Moreover, these figures probably do not include all
incidents that occurred in the relevant time period, as they are
derived solely from OSHA investigation data. The IMIS database, for
example, will not include incidents that involve individuals not
covered by OSHA, e.g., the self-employed. The current IMIS database
generally includes incidents only when they involve at least one
fatality or three or more hospitalizations.
2013 was the deadliest year for communication tower workers since
2006. According to 2013 OSHA incident investigation reports, there were
a total of 15 incidents resulting in 13 fatalities (as well as 3
injuries that required hospitalization). Of the 15 incidents identified
in the 2013 reports, 11 involved falls, and of those falls, 9 were
fatal. Structural collapses accounted for two fatalities, and two
fatalities were the result of employees being struck by suspended
materials while working on a tower (Docket ID OSHA-2014-0018-01).
The leadership of the Department of Labor, OSHA, and the Federal
Communications Commission (FCC) recently organized and participated in
a workshop on communication tower work for industry stakeholders and
government agencies. The event, held on October 14, 2014, included two
panel discussions with representatives from tower climber advocacy
organizations, the owner of a tower erection company, media
representatives, carrier representatives, a tower owner representative,
and a government relations liaison for a wireless infrastructure
industry group. The first panel focused on the causes of tower climber
fatalities and ways employers can prevent such fatalities. The second
panel focused on industry-wide solutions that can be implemented by
carriers, tower owners, and turfing vendors. Chairman Thomas Wheeler of
the FCC and Secretary of Labor Thomas Perez spoke at the event and
called for the agencies and industry stakeholders to collaborate in an
effort to identify best practices and steps that the industry can take
to address the hazards faced by communication tower workers. A video
recording of the event can be found at
C. Training and Certification
Given the highly specialized and dangerous nature of the work that
tower workers perform, employee training and preparation are critical.
Many companies provide training to tower climbers. These training
courses typically last two to five days and consist of a classroom
component and a practical training component, with a final assessment
of skills and knowledge. Topics covered during these courses typically
include: fall protection procedures, climbing safety and planning,
hazard assessments, and basic emergency and rescue protocols. Upon
successful completion of these courses, participants receive a
certification card from the company that provided the training.
Although there is no standard threshold for certification, most
companies that issue certification cards assert that their
certifications meet standards in the National Association of Tower
Erectors (NATE) Tower Climber Fall Protection Training Standard as well
as other applicable standards from OSHA, the American National
Standards Institute (ANSI) and the American Society of Safety Engineers
Recently, there have been some developments in employee training
and preparation resulting from government and industry collaboration.
The Department of Labor's Employment and Training Administration (ETA)
has developed a registered apprenticeship program for tower climbers in
collaboration with a board of stakeholders. The goal of the Tower
Industry Registered Apprenticeship Program (TIRAP) is to provide an
industry-wide standard of training and employee development. The
founding documents for TIRAP were signed on October 14, 2014.
D. Applicable OSHA Standards
At present, OSHA standards do not provide comprehensive coverage of
communication tower construction activities. OSHA's standards for fall
protection in construction (29 CFR 1926, subpart M), which generally
require the use of fall protection at heights of six feet and greater,
will apply in some situations, although those standards do not cover
the erection of new communication towers (see 29 CFR
1926.500(a)(2)(v)). Fall protection requirements for the construction
of new communication towers can be found in 29 CFR 1926.105, which
requires the use of safety nets when workplaces are more than 25 feet
above the ground or water surface, or other surfaces where the use of
ladders, scaffolds, catch platforms, temporary floors, safety lines, or
safety belts is impractical (see 29 CFR 1926.105(a)). Additionally,
communication tower construction activities are exempt from OSHA's
requirements for steel erection activities (29 CFR 1926, subpart R);
subpart R does not cover electrical transmission towers, communication
and broadcast towers, or tanks (29 CFR 1926.750(a)).
Maintenance work on communication towers is governed by OSHA's
general industry standards at 29 CFR part 1910. There are a number of
general industry standards that apply to communication tower
maintenance activities. Most specifically, the telecommunications
standard at 29 CFR 1910.268 applies to the work conditions, practices,
means, methods, operations, installations and processes performed at
telecommunications field installations, such as communication towers
(see 29 CFR 1910.268(a)(1)). A key provision in the telecommunications
standard is Sec. 1910.268(c), which addresses training. That provision
requires employers to provide training in the various precautions and
safe practices described in Sec. 1910.268 and insure that employees do
not engage in the activities to which Sec. 1910.268 applies until such
employees have received proper training. The telecommunications
standard also contains requirements for fall protection (see 29 CFR
1910.268(g)). Paragraph (g) of Sec. 1910.268 generally requires
employers to provide, and ensure the use of, safety belts and straps
when work is performed at positions more than 4 feet above ground, on
poles, and on towers (see 29 CFR 1910.268(g)(1)).
When existing standards do not apply to a particular hazard at a
communication tower worksite, employers still have a duty to protect
employees under the General Duty Clause (section 5(a)(1)) of the
Occupational Safety and Health Act of 1970 (29 U.S.C. 654(a)(1)), which
requires each employer to "furnish to each of his employees employment
and a place of employment which are free from recognized hazards that
are causing or are likely to cause death or serious physical harm to
his employees." OSHA has used the General Duty Clause in some cases
involving accidents on communication towers. For example, in March of
2014 OSHA issued a General Duty Clause citation in a case involving a
double fatality caused by improper rigging on a communication tower.
OSHA found that the employer was aware of, but failed to follow,
industry standards and practices for safely rigging the jump line block
for the gin pole.
E. Consensus Standards and State Standards
There are several consensus standards that address hazards in the
erection, construction, and maintenance of communication towers. The
Telecommunications Industry Association standard TIA-222-G, Structural
Standard for Antenna Supporting Structures and Antennas (Docket ID
OSHA-2014-0018-04), addresses the structural design elements associated
with the fabrication of new, and the modification of existing, antenna-
supporting structures. The TIA-1019-A standard, Standard for
Installation, Alteration and Maintenance of Antenna Supporting
Structures and Antennas (Docket ID OSHA-2014-0018-05), addresses the
loading of communication towers under construction and the use of
specialized equipment, including gin poles, hoists, and temporary guys.
There is an ANSI standard currently under development, ANSI A10.48,
which will address safety practices for the construction and
maintenance of communication towers. This standard may be approved
within the next two years.
Two states have dedicated standards governing communication tower
construction and maintenance. These states, North Carolina and
Michigan, promulgated communication tower standards following multi-
fatality incidents. North Carolina's standard (Docket ID OSHA-2014-
0018-03), which became effective in 2005, covers the construction,
alteration, repair, operation, inspection and maintenance of
communication towers (see 13 NCAC 07F.0600 et seq.). It includes
provisions for employer responsibilities, fall protection and fall
protection systems, non-ionizing radiation, hoists and gin poles, and
employee training. The Michigan standard (Docket ID OSHA-2014-0018-02),
promulgated in 2009, governs construction, alteration, repair,
operation, inspections, maintenance, and demolition activities on
communication towers (see Michigan Administrative Code R 408.42901 et
seq.). It contains provisions on fall protection, emergency response
protocols, training, training certification, hazard identification,
hoists, hoisting personnel, gin poles, catheads, and capstans.
Washington State is planning to update its telecommunications standard
and held stakeholder meetings on the subject in July, 2014.
III. Request for Data, Information, and Comments
OSHA is seeking information to aid it in evaluating the hazards
that workers face on communication towers. The Agency seeks information
on: the types of hazards that communication tower workers encounter;
the types of incidents (both fatal and non-fatal) that occur as a
result of exposure to those hazards; and the best methods employers can
use to address those hazards. The Agency identifies specific issues on
which it is seeking comment later in this section of this RFI.
OSHA requests comments from wireless carriers and all parties
involved in the contracting chain, including turfing vendors,
engineering firms, tower owners, tower construction and maintenance
companies, and field staff, e.g., tower technicians who perform work on
the towers. Based on its review of the information provided by the
public in response to this RFI--and other OSHA research activities--the
Agency will determine what additional actions, if any, to take to
address hazards associated with work on communication towers.
Commenters should identify the role they play with respect to the
performance of work on communication towers and be as detailed as
possible in their comments.
Also, to the extent possible, commenters should identify the specific
question(s) they are addressing (e.g., by referring to the questions
being answered using the numbers provided in the list below).
Questions for Tower Climbers \2\
\2\ While the questions under this heading are specific to tower
climbers, OSHA strongly encourages tower climbers to consider and
respond to all questions in this Request for Information.
1. As a tower climber, what are the most significant hazards that
you encounter on the job? What circumstances or conditions create or
contribute to these hazards?
2. What steps do you take, at this time, to complete your work
safely? What safety-related work practices do you think should be in
3. What safety rules and work practices are provided to you, and
who provides you with that information?
4. Who assigns and oversees your work? Who provides your training
and checks your equipment? When at a jobsite, to whom would you report
a potential safety issue?
5. What specific steps do you think employers can take to make
tower work safer?
6. How, and to what extent, does the design or configuration of
towers, and equipment installed on towers, affect your ability to
complete your work safely?
Training and Certification
7. Tower hands/climbers, please describe the training and
certification required for your job. Employers, please describe the
types of training and certification you require for your employees.
8. What commercial training programs are currently available? What
are the topics covered by the programs? Are the programs adequate to
prepare employees to work safely on communication towers?
9. Is there a need for a standardized, industry-wide training or
10. From your perspective given your role in the contracting chain,
what does a tower climber need to know to do his or her job safely?
11. How do employers evaluate employees to ensure that they have
been adequately trained, especially when employees receive their
training or certification elsewhere? How do companies determine if
employees are proficient in the topics covered by the training or if
re-training is necessary? Do employers offer site-specific training
that addresses specific types of towers and equipment?
12. For employers who contract out work (e. g., carriers, turfing
vendors), what contract language or oversight mechanisms do you use to
ensure that work is done by trained and/or certified workers?
Suitability for Work
13. Are employees directly engaged in tower work assessed for
physical fitness? If so, how? Are physical fitness requirements and
assessments addressed in contracting agreements?
14. What physical limitations should employers be aware of when
assigning an employee communication tower work? What hazards might be
associated with such limitations, and how could those hazards be
Hazards and Incidents
15. Falls: Falls are currently the leading cause of fatalities
among communication tower workers. OSHA believes that many falls result
from the improper use of fall protection equipment or the failure to
use any fall protection equipment at all.
a. How are employers addressing fall hazards?
b. Are employers providing appropriate fall protection equipment to
employees? Is it maintained and replaced when necessary?
c. What factors contribute to employees failing to use fall
protection while climbing or working?
d. Are there situations in which conventional fall protection
(safety nets or personal fall arrest systems) is infeasible? What
alternatives can employees use for fall protection in those situations?
e. What are the ways in which fall protection systems or anchorage
points on communication towers can fail? How can these failures be
f. Should OSHA require built-in fall protection measures on new
towers? Existing towers? Would such a requirement enhance worker
16. Structural issues: When new equipment is added to communication
towers, the additional loading of the tower has the potential to
overload or destabilize the structure. Older towers may need additional
reinforcements to maintain their structural integrity as new equipment
is added to them. Communication tower collapses have resulted in
numerous fatalities in the past two years. Which contractual party
bears responsibility for ensuring that any structural work on the
tower--such as modification or demolition--is done safely from a
structural perspective? What steps are employers currently taking to
17. Hoisting materials and personnel: Base-mounted drum hoists are
often used to hoist materials and personnel to working heights on
communication towers. Hazards arise if hoists that are not rated for
lifting personnel are used for that purpose. OSHA is aware of incidents
in which hoists have failed under such conditions. Also, overloading
material hoists and improper rigging procedures can result in loads
striking the tower structure or workers located on the tower. OSHA
knows of several deaths in the past two years that have resulted from
these types of incidents.
a. When are personnel hoists used?
b. What types of hazards are associated with personnel and material
hoists? What are the best practices for safely managing those hazards?
c. How are capstan hoists used in tower work? In what types of
operations can they be used safely?
d. What are the most common types of rigging hazards that occur on
communication tower worksites? What can employers do to eliminate or
minimize those hazards?
e. Are there methods, other than the use of a hoist or a crane,
that can be used to lift material and personnel at a communication
tower? Which methods and procedures are the safest?
f. What are the roles of different levels of the contracting chain
in managing rigging and hoisting activities?
18. Radio Frequency Hazards: Much research has been done on the
health effects of overexposure to radio frequencies. General health
effects reviews have found that high levels of exposure to radio
frequencies may result in burns. In addition, the link between exposure
to radio frequencies and cancer, reproductive diseases, and
neurological effects has not been thoroughly explored.
a. What methods are employers using to protect workers from
overexposure to radio frequency?
b. Is there a need for employers to institute comprehensive radio
frequency monitoring programs on communication tower worksites? What
would a good program look like?
19. Weather: Communication tower workers work outside during all
seasons, and in all climates. They can be exposed to heat, cold, wind,
snow, and ice. Storm conditions can quickly arise when workers are at
elevation, and it can be difficult to descend the tower quickly.
a. What are the specific weather-related hazards to which
communication tower workers are exposed?
b. How does a crew monitor and respond to changing weather
conditions, including storms?
20. Fatigue: OSHA believes that fatigue can affect communication
tower workers in several ways. Climbing a communication tower is
physically demanding, and OSHA is concerned that fatigue due to
exertion can be hazardous for tower workers. Accelerated work timelines
can also result in tower workers working very long hours. And OSHA
understands that communication tower workers may travel long distances
to reach remote worksites, which can result in workers being fatigued
before they even begin work.
a. What hazards are faced by a worker who finds it physically
challenging to perform expected tasks, such as climbing a tower or
performing a self-rescue? What impact can this have on other crew
b. What are the common causes of worker fatigue at communication
c. What are the effects of fatigue on tower worker safety, and what
types of incidents occur as a result of worker fatigue?
21. Other common hazards:
a. What other hazards are present in communication tower work, and
what types of incidents are resulting from those hazards? What can be
done to protect employees from those hazards?
b. What are some health and safety considerations involved in
working with communications equipment installed on non-dedicated tower
structures, such as water towers, buildings, silos, electrical
transmission towers, etc.?
Contracting and Work Oversight
22. Describe your role in the contract chain and the key safety-
related provisions typically included in your contracts. How do
contracting parties oversee or enforce those provisions? What are the
consequences if a party fails to fulfill those contractual
23. What characteristics of past safety performance does your
company use in selecting potential contractors and subcontractors? What
safety-related criteria does your company use in this selection
24. Are safety-related factors considered in determining whether to
remove a contractor/subcontractor from an ongoing project or from
future selection processes? If so, what specific factors are
25. What are the ways in which the multi-leveled contracting
environment (i.e., where entities such as the carrier, tower owner,
turfing vendor, subcontractor, and contractors hired by the
subcontractor all have some role in the project) impacts employee
safety at communication tower worksites?
26. What practices might companies in the contracting chain adopt
to encourage communication and coordination among employers at tower
work sites? What obstacles stand in the way of communication and
coordination between different parties in the contracting chain?
27. The Agency seeks information on the number and size of firms
that are engaged in communication tower work and on the number of
employees employed by those firms.
28. The Agency seeks information about wage and turnover rates for
employees who work on communication towers. The Agency is also
interested in information about the experience possessed by workers
currently doing communication tower work. Are they usually experienced
in this type of work? Are there many new or inexperienced employees
working on communication towers?
29. What types of equipment are used in tower work and how often is
this equipment repaired and/or replaced?
30. The Agency seeks information from all employers in the
contracting chain about the extent to which employees directly engaged
in tower work are covered by workers' compensation and/or an employer
liability insurance policy.
31. Can towers be designed and built with elevators for lifting
personnel or materials? Can towers be built with booms or davits aloft
to aid in hoisting materials?
32. How would elevators or davits affect productivity/efficiency,
e.g., the amount of time spent on the tower? How would elevators or
davits address or cause any safety hazards at the site? For example,
would elevators or davits address hazards related to employee fatigue?
33. What are the industry standards for providing fall protection
anchor points on new towers?
34. What would be the advantages and disadvantages of an OSHA
standard that covers both construction and maintenance activities on
35. What effects have the North Carolina and Michigan regulatory
approaches had on work practices and climber safety in those states?
36. Should an OSHA standard be limited to work performed on
communication towers, or should it also cover towers used for other
37. If OSHA does not initiate a dedicated rulemaking for work on
communication towers, what other types of regulatory actions might be
necessary and appropriate?
38. What non-regulatory approaches could OSHA take to address
hazards faced by employees working on communication towers?
