What Is an Anchorage Point?

An anchorage point is a designated attachment point for fall protection equipment, forming a crucial part of any personal fall arrest system (PFAS). These points are strategically selected or installed to provide a safe and secure connection for workers using fall protection gear, such as safety harnesses, lanyards, or lifelines. Anchor points are designed to bear the tremendous forces exerted during a fall, preventing the worker from hitting the ground or a lower level.

Anchor points consist of several key components that ensure their ability to support significant weight and forces:

• Anchor Connector: This is the link between the worker’s fall protection equipment and the structure. It could be a D-ring, hook, cable, or other connecting device that ensures the safety harness, lanyard, or lifeline is securely fastened to the anchor point.
• Structural Base: The structural base is the surface or part of the building, scaffold, or other construction to which the anchor point is affixed. It must be capable of withstanding the weight and forces generated during a fall.
• Fasteners and Bolts: In permanent anchor systems, the anchor is often secured with industrial-grade bolts, welds, or fasteners to ensure it remains firmly in place under heavy loads.

Importance of Anchor Points

Anchor points are critical in ensuring the safety and security of workers operating at heights by offering a stable, secure connection for fall arrest and fall restraint systems. The purpose of fall protection anchor points includes:

• Prevention of Severe Injury or Death: Anchor points prevent life-threatening accidents by safely stopping falls before a worker reaches a lower surface or the ground.
• Supporting Fall Protection Systems: Anchor points provide secure attachment points for fall arrest and fall restraint systems, ensuring workers remain safely tethered.
• Mitigation of Fall Forces: Anchor points absorb and distribute fall forces, protecting both workers and the structure from damage during a fall.
• Protection of Workers in Multiple Industries: Anchor points are essential across various industries, offering reliable protection for workers operating at heights.
• Flexibility in Fall Protection Solutions: Anchor points can be customized for different environments, offering flexible solutions for temporary, permanent, or engineered systems.
• Promoting a Safety Culture: Properly maintained anchor points demonstrate a commitment to worker safety, encouraging adherence to safety protocols and fostering a safety-first mindset.

 

How Much Weight Does An Anchorage Point Need to Be Able to Support?

The strength of an anchorage point is one of the most critical aspects of a fall protection system. Without a properly rated anchor point, the entire fall protection system is compromised, putting workers at serious risk. With that, here is an in-depth discussion of the anchor point requirements for fall protection systems.

OSHA Anchor Point Requirements: An Overview

OSHA’s regulations on anchorage points are set forth in 29 CFR 1926.502(d)(15), which requires that each anchor point in a personal fall arrest system must support at least 5,000 pounds (22.2 kN) per worker. This ensures the system can absorb the impact of a fall and stop it safely. However, in certain circumstances, OSHA allows the use of anchorage points that are part of an engineered system designed by a qualified person.

These systems may use anchor points that support less than 5,000 pounds if they are designed to maintain a safety factor of at least two and effectively protect against falls. To comply with OSHA’s fall protection requirements, an effective anchorage point must include several key components:

• Strength: The anchor point must meet or exceed the 5,000-pound load-bearing capacity per attached worker. This applies whether the anchor is permanent or temporary.
• Proper Installation: It must be installed by a qualified individual who understands the forces involved in fall protection and ensures the anchor point is placed in a secure, load-bearing location.
• Compatibility with Equipment: The anchor point must be compatible with the worker's fall arrest system, including the safety harness, lanyard, or lifeline, ensuring seamless integration.
• Accessibility: Workers must be able to reach the anchor point without putting themselves at further risk. Anchor points should be positioned strategically so that workers can easily tether themselves before entering hazardous areas.
• Durability: Whether the anchor point is temporary or permanent, it must withstand the elements, heavy use, and any other environmental factors that could affect its performance. Regular inspection and maintenance are crucial to ensuring the anchor point remains reliable.

Other Standards and Regulations on Fall Protection Anchor Points

Aside from OSHA’s requirements, other organizations have developed standards for fall protection and anchorage points to promote worker safety, such as:

• ANSI/ASSP Z359.1 – Safety Requirements for Fall Protection Systems: Provides additional guidelines for the design, installation, and testing of anchor points in fall protection systems.
• ANSI/ASSP Z359.2 – Minimum Requirements for a Comprehensive Managed Fall Protection Program: Outlines the minimum requirements for developing and implementing a comprehensive fall protection program, including the selection and use of anchor points.
• ANSI/ASSP Z359.18 – Specifications and Design Requirements for Anchorage Connectors: Offers specific design and performance requirements for anchorage connectors, which are the devices used to secure the fall protection equipment to the anchor point.
• ASTM F887 – Standard Specifications for Personal Climbing Equipment: Sets specifications for personal climbing equipment, including anchor points used in specialized industries such as utility and telecommunications.
• NFPA 1983 – Standard on Life Safety Rope and Equipment for Emergency Services: Establishes regulations for anchor points in industries like firefighting and emergency services, where workers frequently operate at dangerous heights.

 

Choosing an Anchor Point

Selecting the right anchor point is a crucial step in ensuring the effectiveness of any fall protection system. The anchor point must be capable of safely supporting the weight and forces generated during a fall, while also being suitable for the specific job environment. 

4 Types of Anchor Points

There are primarily four types of anchorage points used for fall protection. These are:

Permanent Anchor Points

Permanent anchor points are installed as a long-term solution and are typically fixed into the structure of a building, tower, or other sturdy surface. They are often used on rooftops, industrial facilities, or in locations where workers regularly perform tasks at height. 

Temporary Anchor Points

Temporary anchor points are portable and can be set up and removed as needed, making them ideal for short-term or project-based work environments. Common in construction, scaffolding, and maintenance, temporary anchors are designed to be easily attached to structures such as steel beams or concrete surfaces. 

Mobile Anchor Points

Mobile anchor points are designed to move with the worker. These include devices such as mobile lifeline systems or trolley systems that allow the worker to travel along a path while remaining securely attached. Mobile anchor points are commonly used in industries such as window cleaning, telecommunication, and bridge construction, where workers need freedom of movement while working at heights.

Engineered Anchor Points

Engineered anchor points are custom-designed for specific job sites and unique work environments. These anchor points are often created by safety engineers who evaluate the specific needs of the site, the forces involved, and any other factors that might impact the fall protection system. Engineered anchors are commonly used in industries where traditional anchor points are not feasible or where additional safety considerations must be addressed.

Certified vs Non-Certified Anchor Point

These two types of anchors differ in terms of testing, approval, and usage, and the choice between them largely depends on the specific requirements of the job site and the regulatory environment.

Certified anchors have undergone formal testing and certification by a qualified engineer or safety professional to meet specific safety standards. These anchors are evaluated to ensure they can withstand the forces generated during a fall and are designed to meet the load-bearing requirements outlined by these safety regulations.

Certified anchors are most commonly used in permanent installations, such as on rooftops or industrial facilities, where safety standards are more stringent and regulatory compliance is mandatory.

On the other hand, non-certified anchors, while not formally tested or certified by a professional, can still be used in fall protection systems under certain conditions. These anchors are typically selected by a competent person on-site who evaluates the anchor point based on its strength and suitability for the job.

Non-certified anchors are often used in temporary installations, such as during construction work, scaffolding setups, or short-term maintenance jobs, where flexibility and ease of use are prioritized.

Factors to Consider When Choosing an Anchor Point

When selecting an anchor point, several factors must be taken into account to ensure the system is safe and effective:

• Load Capacity: The anchor point must support at least 5,000 pounds per worker or be part of a system with a safety factor of two, and load capacity must be verified before use.
• Location: Anchor points should be positioned for easy attachment and detachment, ensuring safe access without exposing workers to fall hazards.
• Environmental Conditions: Permanent anchor points must resist corrosion and weathering, while temporary anchors should be checked for environmental factors like surface stability or extreme temperatures.
• Duration of Use: Choose permanent anchors for long-term jobs and temporary or mobile anchors for short-term or project-based work.
• Qualified or Competent Person Evaluation: A qualified person (for certified anchors) or competent person (for non-certified anchors) must evaluate the anchor point for strength and proper installation.
• Type of Work Being Performed: The anchor point should suit the type of work; for example, mobile anchors are best for high-mobility jobs, while permanent anchors are ideal for static tasks.

 

How to Install Fall Protection Anchor

Non-certified anchors should be inspected and evaluated by a competent person to ensure they meet the necessary safety requirements.
6. Attach Fall Protection Equipment: Once the anchor point is installed and tested, attach the fall protection equipment to the anchor point. Ensure that all components are compatible with one another and secure the connections before work begins.
7. Recheck the Installation: Before using the anchor point, recheck the entire installation. Verify that the anchor point is properly secured, all equipment is attached correctly, and the system is functioning as intended. 

Safety Tips and Guidelines for Anchor Points

When installing anchor points, it's crucial to always follow the manufacturer's instructions. Each product comes with specific guidelines regarding proper installation, use, and load capacity, which are essential for ensuring the anchor point's effectiveness and safety. Additionally, it's important to use the correct tools and fasteners suited for anchor point installation. Using improper tools can lead to faulty installation, which compromises the anchor point’s strength and increases the risk of failure.

When positioning anchor points, avoid placing them near sharp edges that could damage lifelines or lanyards. If sharp edges are unavoidable, protective measures, such as edge guards, should be used to prevent fraying or cutting of the fall protection equipment. Lastly, anchor points should be installed directly above the worker whenever possible. This minimizes the swing fall effect, reducing the distance of a fall and allowing the fall arrest system to activate more quickly, enhancing worker safety.

Anchor Point Inspection and Maintenance

Regular inspection and maintenance of anchor points are necessary to ensure the long-term safety and functionality of fall protection systems. Here are some points to remember when conducting anchor point inspection and maintenance:

• Initial Inspection: After installation, a qualified person must inspect the anchor point to ensure it meets all safety requirements, and the inspection should be documented.
• Routine Inspections: Permanent anchor points should be inspected regularly as part of maintenance, while temporary anchor points need inspection before each use.
• Check for Environmental Damage: Inspect anchor points for environmental wear, such as corrosion or UV damage, and apply protective coatings or take corrective actions as needed.
• Fastener Integrity: Ensure all fasteners are tight and free from cracking or deterioration, replacing any worn or damaged fasteners during inspections.
• Documentation: Keep detailed records of all inspections, including dates, issues, corrective actions, and the inspector’s name, for compliance purposes.
• Replace Worn or Damaged Anchor Points: Replace any anchor point that shows signs of significant wear, corrosion, or damage, as they may no longer be safe for use.
• Re-certification of Anchor Points: Periodically re-certify certified anchor points by re-testing them to verify they still meet load-bearing and safety standards.

Selecting and properly installing fall protection anchors is a critical component of any fall arrest system to ensure the safety of every employee attached. Whether you're using a non engineered anchor point or an anchor capable of withstanding the maximum arresting force, it is essential to provide a secure point for workers.
