• Yellow: Non-critical issues identified that should be corrected, when possible, but is not an immediate concern.

• Red: Critical issues identified that may affect personnel safety, cause a system outage, or damage to equipment. These issues require immediate attention or should be condemned. A Do Not Climb sign is installed if the structural integrity of the tower is compromised.

Life-Safety Compliance

PRIORITY LEVEL: 2 DEFICIENCY DESCRIPTION WITH RECOMMENDED CORRECTIVE ACTION (RCA):

-No lightning protection system (including down conductors and air terminals) has been installed on the tower. RCA:

Install an LPS to include an air terminal, down conductors, and tie into an earth electrode system in accordance with NFPA 780 Section 4.

-Structural bonding is detached from leg B and not properly grounding the tower to an earth electrode system. RCA:

Ensure all legs of the tower are properly bonded to an EES in accordance with NFPA 780 Section 4.

Reference: OSHA Deficiencies (OSHA Standards), Electrical Safety Deficiencies (NEC and NFPA 780) industry best practices), and Hazardous Conditions (issues of concern, life threatening).

Mission Capability

PRIORITY LEVEL: 2 DEFICIENCY DESCRIPTION WITH RECOMMENDED CORRECTIVE ACTION (RCA):

-The FAA tower mapping/structural analysis is adhering to the current version TIA-222 which stipulates that guyed towers are analyzed once every three years and self-supporting structures analyzed once every five years. It is recommended that subsequent inspections follow the TIA-222 standard.

-The sleeve inside the eye loop for guy wire leg C at 40 feet has started to work its way out. RCA: Replace the sleeve and ensure the connection is compatible.

-Transmission lines are unsupported between the tower and the adjacent building. RCA: Install an ice bridge for proper transmission line support and protection.

-The weatherproofing around the connectors has degraded at 45 and 130 feet. RCA: Use industry standard weatherproofing materials to seal the transmission line connection.
