Single Point Anchor Fall Protection Design Considerations
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.

Rooftop single point anchors can be used in conjunction with a variety of deck substrates including metal standing seam, rubber membrane, or concrete.  Single point anchors can be mechanically attached to structural steel members overhead, or mounted to walls and rooftops.

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.

Single Point Anchor Applications

• Rooftop Maintenance and Roofing
• HVAC Maintenance
• Aircraft Hangars
• Window Washing
• Construction and Steel Erection
• Trains
• Trucks and Buses

AT DFP, we recognize that each fall protection scenario is unique, requiring a comprehensive hazard assessment and customized solution. From indoor overhead installations to rooftop applications at foot level, our safety engineers have a complete range of single point anchor solutions to ensure personnel safety and complete compliance with all OSHA fall protection regulations.

Single Point Anchors
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 Arrest Systems
1926.502(d)(16)
Personal fall arrest systems, when stopping a fall, shall:
1926.502(d)(16)(ii)
limit maximum arresting force on an employee to 1,800 pounds (8 kN) when used with a body harness;
1926.502(d)(16)(iii)
be rigged such that an employee can neither free fall more than 6 feet (1.8 m), nor contact any lower level;
1926.502(d)(16)(iv)
bring an employee to a complete stop and limit maximum deceleration distance an employee travels to 3.5 feet (1.07 m); and,
1926.502(d)(16)(v)
have sufficient strength to withstand twice the potential impact energy of an employee free falling a distance of 6 feet (1.8 m), or the free fall distance permitted by the system, whichever is less.
