Overview

The Frontline Vertical/Horizontal Beam Anchor is a fixed I-beam anchor designed for use as a component in a Personal Fall Arrest System (PFAS). It is engineered to clamp onto either vertical or horizontal I-beams, creating a secure anchor point for fall protection. The device is intended for use by trained personnel in fall protection and is designed to meet or exceed applicable ANSI Z359.18, OSHA 1910, and OSHA 1926 fall protection standards.

Function Description

The primary function of the Beam Anchor is to provide a reliable attachment point for personal fall protection systems. It allows workers to safely tie-off while maintaining mobility and productivity in elevated work environments. The anchor is designed to dissipate energy during a fall, limiting the deceleration forces exerted on a worker. It is crucial that the anchor is used as part of a complete personal fall protection system, which typically includes an anchorage, connectors, a body harness, and may also include a lanyard, deceleration device, or lifeline.

The Beam Anchor facilitates both fall arrest and fall restraint applications. In a fall arrest scenario, it is used to stop a worker's fall from a working level, preventing them from contacting a lower level. For fall restraint, the system limits a worker's movement, preventing them from reaching a fall hazard. The anchor can also be used for work positioning, allowing an employee to be supported on an elevated vertical surface with both hands free.

The design incorporates adjustable beam clamps, a hex bar, nylon bushing, a D-ring, safety pins, and a double locking mechanism. The adjustable clamps allow the anchor to be secured to I-beams of various flange widths. The D-ring serves as the attachment point for connecting devices such as lanyards or self-retracting lifelines. The safety pins and double locking mechanism ensure that the anchor remains securely fastened to the beam during use.

Usage Features

Before using the Beam Anchor, users must read and fully understand the instruction manual. Proper training in fall protection, including rescue programs, is mandatory. The anchor should only be used in workplace applications and not for material handling, recreational, or sports-related activities.

Installation of the Beam Anchor involves several key steps to ensure safety and proper function. First, the I-beam must be clear of obstructions and fully installed as part of the structure. The anchor is primarily designed for overhead applications, but if foot-level tie-off is required, other connecting devices suitable for such applications must be used. It is important to note that the beam anchor is intended for horizontal I-beam applications only, not vertical ones.

To install, the outer and inner retainer nuts are loosened to create an opening large enough for the beam flange to fit between the beam clamps. Once positioned over the beam flange, the locking nuts are turned clockwise to secure the anchor. The beam clamps must be closed symmetrically on the beam. After installation, the stability of the connection must be checked to ensure there is no possibility of self-acting disconnection. Additionally, the ends of the I-beam should be enclosed to prevent the anchor from sliding off.

When connecting to the anchor, only approved snaphooks or carabiners that meet OSHA and ANSI standards should be used. These connectors must be of the locking type to prevent unintentional disengagement. Visual inspection and a pull test are required to ensure the connecting equipment is locked and fully functioning. Only one PFAS should be connected to a Fall Arrest Anchor at a time. It is crucial to avoid inappropriate connections, such as connecting two snaphooks to each other or to a single D-ring, loading the gate, or attaching in a manner that prevents full locking.

Users must be aware of potential hazards, including sharp/abrasive surfaces, moving machinery, thermal, electrical, and chemical hazards. Swing falls must be avoided by installing the anchorage point directly above the work area whenever possible. The total fall clearance distance must be calculated before use, considering factors like lanyard length, deceleration distance, worker height, D-ring shift, and a safety factor.

Maintenance Features

Regular inspection and maintenance are critical for ensuring the safety and integrity of the Beam Anchor. Prior to each use and installation, the authorized user or rescuer must inspect the product. A competent or qualified person, other than the user, is required to conduct thorough safety inspections every 6 months or sooner, as necessary or required by the employer.

Key inspection points include:

  • Safety labels/markings/tags: Ensure they are legible and include appropriate OSHA/ANSI markings, product limitations, and user capacity.
  • Physical condition: Check for any defects such as corrosion, broken or bent components, deformities, excessive wear, or defects in welded areas. Any evidence of damage or alterations affecting the safety functionality of the anchor warrants its removal from service.
  • Functionality: Verify that the nylon bushing is in place and secure, that all locking nuts turn and lock properly, and that safety pins are in place and secured on both sides.
  • Impact events: Any product that has been subjected to a fall or impact must be immediately removed from service.

The product must be kept clean and free of surface contamination such as concrete, stucco, roofing material, or other substances that could impact its safe use. Equipment exposed to rain, dirty water, or construction materials should be cleaned and dried before storage. Chemically exposed equipment that cannot be cleaned with water and soap must be removed from service.

Repairs and maintenance can only be performed by Frontline Fall Protection. End users or other companies are not authorized to repair or maintain Frontline Fall Protection products. If a product fails inspection or its safety is questionable, it must be taken out of service immediately and Frontline Fall Protection must be notified for further action.

For storage, if the products are not permanently installed, they should be stored at room temperature in indoor spaces, lockers, or clean areas, away from sunlight, rain, and other environmental conditions. Storage areas should also be free from chemicals, oils, paint, or other contaminants that could compromise the product's integrity.

During transport, care must be taken to prevent the product from bumping against other items, which could cause damage. The product should also not be transported with harmful substances or chemicals that could compromise its integrity. All inspections must be documented for recordkeeping purposes.
