1. SBA’S COMMITMENT TO SAFETY

SBA Communications Corporation (“SBA”) is committed to providing a safe and healthy work environment for the protection of our most vital resource – our employees. The bottom line – “No work assignment is so important that it should be performed in an unsafe manner”.

SBA’s basic philosophy is that all injuries and accidents can be prevented. All employees, at every level, are expected to accept responsibility for their own safety and the safety of those with whom they work. There is no place in this organization for an unsafe employee. ALL SBA employees are subject to disciplinary action for failure to comply with established health and safety requirements.

SBA will provide all required safety equipment to its employees. It is your responsibility to use and care for the safety equipment as instructed and to notify your supervisor immediately if you do not have proper safety equipment or if your safety equipment is defective.

2. INCIDENT REPORTING

2.1. Reporting of Work-Related Injuries/Illnesses and Near Misses

The reporting, investigation, and documentation of work related injuries/illnesses and near misses is recognized as the most important first-step in controlling and preventing workplace accidents.

The proper SBA form shall be used to report any work-related incident. All forms shall be completed immediately following the incident and returned to your Health and Safety Manager and Insurance Administrator. Investigations of incidents will be conducted as soon as possible following the incident.

SBA’s Worker’s Compensation Reporting Worksheet shall also be completed if the injured party seeks medical attention. The Supervisor, in conjunction with the injured employee, must complete the form. Any position included in Exhibit A of SBA’s Drug and Alcohol Policy must undergo mandatory post-accident drug screening.

If the work-related injury does not require medical attention, SBA’s First-Aid Report must be completed and returned to your Health and Safety Manager.

2.2. Motor Vehicle Accidents

A verbal report of all motor vehicle accidents shall be made immediately after an accident. SBA’s Collision Reporting Form must be completed and submitted the day of the accident to the Health and Safety Manager..

A post-accident urinalysis may be required after the accident. Contact SBA’s Health and Safety Manager or your Insurance Administrator for instructions.

3. EMERGENCY PLANNING AND RESPONSE

SBA requires that all project sites take the steps necessary to properly plan and prepare for emergencies (e.g., fires, tornadoes, hurricanes, medical, inclement weather, snow/ice storms, etc.) which may occur on our project sites.

The Pre-Work Assessment Survey Form contains all local emergency services numbers, company contact information, and directions to the work site and nearest hospital. A designated Evacuation Point (Safe Area) that will serve as a gathering point in the event of an emergency shall be identified and communicated to all site personnel.

All SBA worksites shall have a minimum of one person on site at all times who holds a current First-Aid and Cardio- Pulmonary Resuscitation (CPR) certification from the American Red Cross (or equivalent).

When contacting emergency services, the primary method will be by cellular telephone. If cellular service is not available on the work site, field supervision shall determine the nearest communication point that cellular service is available.

2 | P a g e

When an emergency situation occurs, one person will be given the responsibility to go to the designated location and make the call to the required emergency services.

4. TOWER SITE SECURITY

• The welder will then precede to the next location for the port cutting.

• Only one welder is permitted to weld on the structure at any one time. No simultaneous welding.

• Pictures are to be taken of all the welded ports.

16. ELECTRICAL

• All SBA employees and subcontractors shall be informed of the existence and associated hazards posed by the energized electrical systems that exist on the project site through the Pre-Work Assessment Survey.

• All electrical circuits must be placed into an “electrically safe work condition” (i.e., de-energized, locked out, and tested/verified, prior to performing work on the electrical components, equipment and wiring, etc.). Working on “live”, energized electrical components, equipment, and wiring is not permitted, except when de-energizing the equipment introduces additional or increased hazards or is not feasible due to equipment design or operational limitations.

16.1. Safe Electrical Work Practices

• Operating Electrical Disconnects – Ensure that the door or panel cover of the switch compartment is closed and securely latched or in place and fastened properly. Before operating the switch, stand to the side of the enclosure door or cover to position yourself away from the line of fire should an arc blast occur. Look away from the switch and use your non-dominant hand to operate the switch while keeping the free hand from making contact with any surface of the equipment or surrounding structure.

• Working Space and Clearances – To prevent electrical shock, personnel must maintain a safe distance from any energized electrical wiring or equipment operating at 50 volts or more. Keep areas in front of all electrical cabinets and panels clear for 36 inches and ensure the access door can be opened at least 90 degrees.

• Work Near Overhead Power Lines – Any nonqualified person, vehicle, or mechanical equipment working in an elevated position near overhead power lines must maintain at least a 10 foot clearance (in reference to the closest conductive object near the power line) for voltages to ground of 50 kV or below and an additional 4 inches for every 10 kV over 50 kV. If work is to be performed on overhead lines closer than the clearance requirements as identified under Working Space and Clearances, the lines must be de-energized and grounded, insulated, and/or the work performed by a Qualified Person(s).

15 | P a g e

• Electrical Boxes and Cabinets – Each outdoor box will be weather-tight, and have a cover, faceplate, or fixture canopy. All openings not in use will be closed with a plug or cover.

• Standard PPE for qualified electrical personnel include a flame retardant shirt and pants with minimum rating of 8 cal/cm2 with cotton t-shirt, voltage-rated hard hat, safety glasses, and hearing protection. Shirt sleeves shall be completely rolled down and fastened at the wrist. From this minimum, the arc flash labeling or system voltage level present will be used to determine the PPE level required.

• Dielectric insulated gloves (00 rated voltage gloves) with leather outer glove will be used while performing energized electrical work on systems above 250 volts to ground. Gloves should be certified once every six months.

• Wearing conductive jewelry or clothing (e.g. watch bands, bracelets, rings, necklaces, key chains, cloth with conductive thread) while performing electrical work is strictly prohibited.

• Lockout Tagout Procedure

• Notify all affected persons of the pending lockout.

• Identify all sources of power required to be de-energized and locked out

• Prior to the voluntary use of nuisance-dust masks, workers must complete a Dust Mask Request Form and be trained in the proper use of dust masks.

• Only filtering face pieces (commonly known as “dust masks”) will be used for nuisance exposures. No “cartridge” air purifying or any air-supplying respirators will be used for controlling nuisance exposures.

• Requests for use of air-purifying or supplied-air respirators shall be reviewed and approved by the Health and Safety Manager.

19. HAZARD COMMUNICATION

• A chemical inventory list and Material Safety Data Sheets (MSDSs) will be maintained by the SBA Safety Department and these documents are available to SBA employees and subcontractors through the SBA Portal or by request.

• All containers of hazardous materials must be labeled. It is the responsibility of the employee using the material to ensure that the label is present.

• If labels on original containers are found to be inadequate, illegible or otherwise unacceptable, the material will be held until your Safety Manager has determined if the material will be accepted, and what label is to be applied.

• All secondary container labels must be completed and the label applied before the transfer of the material into the container. If a container has been used previously, the original label must be removed or defaced so that only one hazard label is on the container.

• Material Safety Data Sheets (MSDS) for all hazardous material to which employees are or may potentially be exposed will be obtained and made readily available to all employees.

• The supervisor or crew leader will arrange for employee information and training of existing hazardous materials at the time of initial assignment and whenever a new hazardous material is introduced into the work area.

• Subcontractors are required to provide hazard information for any chemicals with potential exposure affects that are brought onto the jobsite or produced on the jobsite, outside of consumer articles.

• SBA employees will receive information and training on existing hazardous substances at the time of initial assignment and whenever a new hazardous substance is introduced into the work area.

20. RF/EME SAFETY

• Maximum Permissible Exposure (MPE) – the Maximum Permissible Exposure (MPE) is a maximum level of exposure that is specified by the FCC. The MPE is based on frequency, as illustrated in Chart 1 below. The Occupational/Controlled MPE applies in areas where exposure is related to employment duties. The General Population/Uncontrolled MPE applies to persons assumed to have no knowledge of or control over their potential exposure to EME energy.

19 | P a g e

FCC Adopted Maximum Permissible Exposure Limits

• Electromagnetic Energy (EME) / Radio Frequency Energy (RF) – RF is a form of EME used for transmitting radio signals. EME/RF is a type of non-ionizing radiation. Other examples of non-ionizing radiation include laser, radar, microwaves, UHF/VHF AM broadcast, paging systems, and infrared. Damage to the body from EME/RF overexposure is dependent upon time, distance, and shielding from the EME/RF source.

• Time-averaging - Maximum Permissible Exposures are expressed as time-averaged exposures (typically 6- minutes for Occupation/Controlled MPE). The use of time averaging to regulate total exposure allows an individual to work in an area with higher energy levels for shorter durations.

20.1. General Work Practices:

• Assume all antennas are active.

• Before working on antennas notify owners and disable appropriate transmitters. Work on a specific antenna should only be accomplished after the attached transmitters have been turned off. This should be attempted only after contacting the owners or operators. Coordination will help ensure that turning off the equipment will not cause serious disruption of the service;

• Maintain safe clearance from all antennas. A small increase in distance from an antenna can have a substantial effect on reducing the EME exposure.

• Do not stop in front of antennas.

• When climbing a tower, workers should select rest points away from antennas. Workers should always try to keep below or behind antennas to minimize their exposure to the main beam of the antenna.

• Use personal EME monitors while working near antennas. When multiple employees are working at an EME site, the “highest risk” employee (the one who will be working closest to the antennas) should be the one wearing the monitor;

• Never operate transmitters without shields during normal operation.

• Do not operate base station antennas inside equipment rooms. Using antennas inside equipment rooms can increase the exposure to EME levels above FCC guidelines and create undesirable radio frequency interference;

• Antenna sites must have physical access control. This is accomplished by fencing around the compound.

• When other transmitters are involved, power reduction, lock-out/tag-out, or other control procedures may be necessary.

20 | P a g e

20.2. Electromagnetic Energy Site Signage

The Federal Communication Commission (FCC) has developed guidance for EME/RF site signage through use of Zones (Blue, Yellow, and Red). To comply with FCC site signage requirements, radio tower and rooftop sites shall be posted in accordance with the following:

• Blue Zone (Notice) The blue zone is an area where the time-weighted exposure is below 20% of the Occupational/Controlled MPE. There is no time limit or special work practices required for this zone and only basic EME awareness is needed.

• Yellow Zone (Caution) The yellow zone is any area where the time-weighted exposure is between 20% - 100% of the Occupational/Controlled MPE. In this zone, the energy fields are within acceptable exposure limits, however areas adjacent may exceed acceptable limits. Only personnel with the appropriate training, knowledge, and understanding of EME procedures should work in this area.

• Red Zone (Warning) The red zone is any area where the time-weighted exposure levels are above 100% of Occupational/Controlled MPE. Areas determined to require red zone classification require special procedures, engineering controls, and restricted access. Examples of the procedures that may be implemented include:

• Restricted site access; • Lockout/tagout of transmitter equipment during maintenance;

• Re-engineering site to reduce EME fields; or

• Control of antenna types used on the site.

20.3. Personal Protective Equipment (for EME/RF)

While SBA does not routinely require the use of PPE for control of EME/RF hazards, a particular site or type of EME/RF hazard may warrant the need for specialized PPE. In this event, the SBA Health and Safety Manager will communicate with field supervision for specific PPE selection. Each employee must inspect the protective clothing to ensure it is in good condition prior to each use.

20.4. Employee Information and Training

All personnel entering an active SBA site that is demarcated as a yellow or red zone shall have EME/RF awareness training. More advanced EME safety training is required for all employees who may work in

fields above the occupational/controlled environment limits (red zone).

21. POWER & HAND TOOLS

21.1. Power Tools

• Tool manufacturer guards shall remain in place and unaltered.

• Point-of-operation guards may require ongoing adjustment to perform correctly (portable grinders) or may be self-adjusting (circular saw blade guard).

• Electric hand tools shall be double insulated;

• All electric hand tools when used in the field, within six feet of water, or in rain shall be plugged into a GFCI receptacle or be equipped with GFCI protection;

21 | P a g e

• Pneumatic power tools shall be secured to the hose by some positive means (i.e. quick connect). Never use air hoses or extension cords for raising or lowering tools and materials to and from the work area;

• All fuel-powered tools shall be in the off position during refueling or while performing maintenance repairs;
