Tip Over Post Single Point Anchors

Tip Over Post Single Point Anchors are designed for rooftop applications with pitches of 4:12 and less.  When engaged during a slip or fall, the post tips over, dispersing the energy and preserving the structural integrity of the roof.  Tip Over Post Single Point Anchors can be utilized with a wide variety of roofing substrates including single ply membrane, built-up asphalt, metal, and standing seam metal roofs.  Single point anchors are cost effective and easy to use, making them an ideal fall protection solution for clearly designated work areas in which a wide range of motion is not required.  If the work area is larger than what we term “the 30 degree cone of safety,” we recommend a horizontal lifeline for maximum worker mobility.  If you have questions about the suitability of a fixed anchor point for your application, please contact the safety experts at Diversified Fall Protection for additional information.

Design Considerations

Tip Over Post Single Point Anchors are designed for pitches of 4:12 and less.  Tip Over Post SPA systems include an integral base plate, post, and D-ring anchor designed for attachment of a self retracting lifeline (SRL), lanyard, or a lifeline. The base allows for installation to a variety of roof designs and materials. When subjected to fall arrest forces, the post will tip over to reduce uplifting loads on the roof decking. Unlike Rigid Post Single Point Anchors which are are commonly attached structural steel members beneath the roof deck, Tip Over Post Anchors may be installed with minimal or no penetration of the roof in the case of metal deck, concrete or standing seam metal applications.  The minimum required thickness for standing seam metal roofs is 24 gauge. Non-engineered single point anchors must be rated rated at 5,000 for one user or 10,000lbs for two users.  Engineered systems must be designed for 2 times the applied load in the event of a fall by a qualified person.  A single point anchor may be designed for single or dual tie-off as long as each user attaches to a designated D-Ring.  Multiple users should never tie off to the same D-Ring under any circumstances. Special care must be taken to train personnel in the proper use of single point anchors.  An SPA is designed to protect workers within a 30 degree conical cone; moving outside the intended coverage area increases the likelihood of coming into contact with structure below the work area in the event of a swing fall.

OSHA Regulations

  • Tip Over Post Single Point Anchor OSHA Regulations
    • 1926.502(d)(15) Anchorages used for attachment of personal fall arrest equipment shall be independent of any anchorage being used to support or suspend platforms and capable of supporting at least 5,000 pounds (22.2 kN) per employee attached, or shall be designed, installed, and used as follows:
    • 1926.502(d)(15)(i) as part of a complete personal fall arrest system which maintains a safety factor of at least two; and
    • 1926.502(d)(15)(ii) under the supervision of a qualified person.

Personal Fall Protection System This section is applicable if the personal fall protection system is being used by an employee having a combined body and tool weight of LESS THAN 310 pounds (140 kg). NOTE: Additional requirements for personal fall arrest systems and positioning systems for an employee having a combined body and tool weight of MORE THAN  310 pounds are contained in paragraphs (d) and (e) of OSHA 1910.140. The employer must ensure that personal fall protection systems meet the following requirements:

  • Connectors must be drop forged, pressed or formed steel, or made of equivalent materials. 1910.140(c)(2)
  • Connectors must have a corrosion-resistant finish, and all surfaces and edges must be smooth to prevent damage to interfacing parts of the system. 1910.140(c)(3)
  • When vertical lifelines are used, each employee must be attached to a separate lifeline. 1910.140(c)(4)
  • Lanyards and vertical lifelines must have a minimum breaking strength of 5,000 pounds (22.2 kN). 1910.140(c)(5)
  • Self-retracting lifelines and lanyards that automatically limit free fall distance to 2 feet (0.61 m) or less must have components capable of sustaining a minimum tensile load of 3,000 pounds (13.3 kN) applied to the device with the lifeline or lanyard in the fully extended position. 1910.140(c)(6)
  • A competent person or qualified person must inspect each knot in a lanyard or vertical lifeline to ensure that it meets the requirements of paragraphs (c)(4) and (5) of this section before any employee uses the lanyard or lifeline. 1910.140(c)(7)
  • D-rings, snaphooks, and carabiners must be capable of sustaining a minimum tensile load of 5,000 pounds (22.2 kN). 1910.140(c)(8)
  • D-rings, snaphooks, and carabiners must be proof tested to a minimum tensile load of 3,600 pounds (16 kN) without cracking, breaking, or incurring permanent deformation. The gate strength of snaphooks and carabiners, must be proof tested to 3,600 lbs. (16 kN) in all directions. 1910.140(c)(9)
  • Snaphooks and carabiners must be the automatic locking type that require at least two separate, consecutive movements to open. 1910.140(c)(10)

Snaphooks and carabiners must not be connected to any of the following unless they are designed for such connections: 1910.140(c)(10)(i)

  • Directly to webbing, rope, or wire rope; 1910.140(c)(10)(ii)
  • To each other; 1910.140(c)(10)(iii)
  • To a D-ring to which another snaphook, carabiner, or connector is attached; 1910.140(c)(10)(iv)
  • To a horizontal life line; or 1910.140(c)(10)(v)
  • To any object that is incompatibly shaped or dimensioned in relation to the snaphook or carabiner such that unintentional disengagement could occur when the connected object depresses the snaphook or carabiner gate, allowing the components to separate. 1910.140(c)(11)
