BRIDGE WORK

Fall protection challenges:

• When constructing a new bridge, no overhead anchor points are available for the crew to connect a lanyard or self retracting lifeline. The anchorage must be provided through the installation of a horizontal system or fall protection equipment must be specially designed to use the beam itself as an anchorage.

• Most bridge work requires a great deal of horizontal mobility to enable workers to move along the structure and to do decking work in between. If the worker is connected to one fixedpoint, mobility is limited.

• Workers must move along narrow walks. The proper horizontal installation will provide handholds to enhance safety.

• Some horizontal systems are designed to be connected to steel I-beams. Concrete bridge work requires a horizontal system that clamps around rebar or is permanently secured into the concrete itself.

The A, B, C’s of Personal Fall Protection
C. H. Bull Co. offers a complete array of passive and active fall arrest systems.
The basics of every personal fall arrest system can be described as the ABC’s of fall arrest.
ANCHORAGE - Anchorage means a secure point of attachment (structure) for the fall arrest system. The type of anchorage varies with the industry, the job being performed, the type of installation and the structure available. The anchorage connector provides a means of attaching the system to the anchorage (structure).
BODY SUPPORT - Full body harnesses provide a connection point on the worker for the personal fall arrest system. Depending on the application, they can be used as part of a system to protect the worker from falling and to limit the extent of potential injury in case of a fall.
CONNECTORS - Connectors are devices used to connect the worker’s full body harness to the anchorage system. Connectors include lanyards, snap hooks, carabiners, deceleration devices and specialty systems such as self retracting lifelines, ladder climbing systems, vertical lifelines and rope grabs.
DESCENT/RESCUE - Rescue and retrieval of a fallen worker is a required component of any Fall Protection Program.
Recommendations in this section are for general application guidance. Product choices may vary depending on specific performance requirements.

More than 6’ mobility
 Ultra-Lok® Self Retracting Lifeline - Stainless steel working components, 11’ (3.3m) nylon web with reserve lifeline, self-locking swivel hook, swiveling anchorage loop and impact indicator. 3103108
More than 6’ mobility
 Talon® Self Retracting Lifeline - Compact and lightweight design features 8’ (2.4m) nylon webbing lifeline. The brake system incorporates all metal components for durability. A unique quick-connect handle for direct attachment to the anchorage or harness sets this unit apart. It also includes an impact indicator for added safety. 3101001
Less than 6’ mobility required
 ShockWave2™ Shock Absorbing Lanyard - ShockWave2™ shock absorbing lanyards are stretchable for complete freedom of movement. They expand to 6’ (1.8m) & contract to 4-1/2’ (1.4m) in reaction to your movements, reducing trip hazards. The ShockWave2™ incorporates a unique inner core that immediately begins to extend and absorb energy during a fall. 1244306
Tying off at the feet
 Force2™ Shock Absorbing Lanyard - The Force2™ shock absorbing lanyard is used when there is no overhead anchorage, and your only option is to tie off at your feet. Because this creates a much greater free fall distance, standard shock absorbers will bottom out, putting dangerous forces on your body. The Force2™ shock absorbing lanyards allow a 12’ (3.7m) free fall and still keep forces below OSHA’s limits when tying off at your feet. 1245006
