Anchor points are critical components of fall protection systems, providing secure attachment points for connecting personal fall arrest equipment like harnesses and lanyards. The type of anchor point used depends on the specific task, work environment, and structure. Here are three common types of anchor points, along with their load requirements and inspection methods:
1. Structural Steel Members:
Description: Structural steel members, such as beams, columns, and trusses, are often used as anchor points in construction, manufacturing, and industrial settings. These members are usually part of the permanent building or structure. They are usually I-beams, wide flange beams, or channel members.
Load Requirements: Anchor points used in fall arrest systems must be capable of supporting a static load of at least 5,000 pounds (22.2 kN) per worker, or designed, installed and used under the supervision of a qualified person as part of a complete personal fall arrest system which maintains a safety factor of at least two. When used for fall restraint, they must withstand 2 times the anticipated static load. The design and load rating must always be done by a qualified person. These load ratings ensure that the anchor point can withstand the forces generated during a fall without failing. Structural steel members are generally rated for this level of load, but their capacity must be confirmed.
Inspection Methods:
Visual Inspection: Before using a steel member as an anchor point, conduct a thorough visual inspection. Look for any signs of deformation such as bending, twisting, or cracks in the steel. Check for corrosion, rust, and excessive wear. Look for any alterations or welds that might compromise the integrity of the member. If any of these are found, the anchor point is unsuitable. For example, a cracked steel beam would not be appropriate, as it might fail under load.
Connection Integrity: Examine how the connection device attaches to the steel member. Check the clamping device for tight connections, and that it’s firmly gripping the steel member. Ensure there is no movement of the connection device and that it’s properly locked. Verify that the beam clamps are properly installed, in line with the manufacturer’s directions, and that the clamp is rated for its required use. Check that all bolts, nuts, or screws are tight and not damaged.
Load Rating Verification: Confirm that the load rating of the steel member is sufficient for the intended application. When using a beam clamp, ensure that the clamp is rated....
