5. Performance Requirements
5.1 Safety Practices—Safety practices should follow the guidelines of OSHA 29 CFR Part 1926 and other state and local regulations. The installer should refer to OSHA, state, and local regulations before work begins. These guidelines will address confined spaces, a competent person, safety training, structural hazards, trench safety, manhole safety, traffic safety, and equipment safety. 5.1.1 Confined Spaces—Perhaps the most dangerous ele- ment ofsafety risk is exposure to underground confined spaces. In the United States, OSHA requires that confined space entrants, attendant, entry supervisor, and rescue team be trained, provide special equipment, and follow certain proce- dures when entering a manhole or underground sewer. The attendant must be equipped to test the atmosphere, monitor the atmosphere and the crew, control the activities in the confined space, and call an emergency response team for any accident. Besides the air atmosphere, the confined space crew must recognize and protect members from sewage or water in the sewers, which can injure or drown a crew member. 5.1.2 Structural Hazards—When cleaning, inspecting, re- pairing the sewer, or installing and maintaining and changing the fiber and conduit, the crew should inspect entry structures and large diameter sewers for structural deficiencies, and consider possible point collapses, which could flood the pipe with sudden infiltration, or subject the crew to other hazards. Therefore, appropriate judgment and other precautions should be considered. 5.1.3 Trench Safety—Some open trench work or directional drilling is required for interconnections and for final connec- tions to users and other telecommunication companies. A competent person trained to recognize dangerous conditions and to protect the crew must be on site. The most common safety concerns in open trench work are cave-ins and other utility hits. 5.1.4 Traffıc Safety—Crews cleaning, inspecting, repairing, installing optical fiber and conduit, repairing sewers and manholes, and installing new conduit in open trench may be exposed to traffic. U.S. DOT MUTCD Part VI requires that traffic control devices and flaggers must be in place to protect the crew and the public, if there is exposure to traffic. A competent person should be in charge of these activities. N OTE 1—The AGC 4 offers information on Safety, Constructability, Liability and Risk Management, and Partnering through its website. Additional information about constructability issues is available at the website https://www.engr.wisc.edu/cee/, which is the “Constructability Analysis” course at the College of Engineering, University of Wisconsin- Madison. 5.1.5 Equipment Safety—All construction equipment and personal protective gear must meet OSHA regulations, and be in good repair. Crew members should receive proper training in safety for all exposures, and weekly (more frequent if war- ranted) safety meetings should be conducted to identify antici- pated hazards, and plan appropriate processes to protect the crew and public from injury or death. Prior to starting a project, a safety plan should be prepared by the installer or owner’s designated representative. This plan should be implemented and followed during the construction. N OTE 2—Safety videos are available from various vendors, including a variety from the AGC. 5.1.6 Manhole Safety—Whenever optical fiber devices are installed in manholes, certain procedures are used to protect people entering the confined space in the future. Cable bend guards are to be closed to avoid a tripping and entanglement hazard. Where practical, splice enclosures are to be installed next to the manhole steps or ladder so that workers or rescue workers can get into the manholes with self-contained breath- ing apparatuses without hindrance or risk of entrapment.
