Fall protection experts evaluate whether a worksite provided the fall protection the law and the applicable consensus standards required, whether the systems in use were selected and installed correctly, and whether the worker was trained to use them. This is the single most-cited area in American occupational safety enforcement: OSHA's construction fall protection standard, 29 CFR 1926.501, has held the top position on the agency's list of most frequently cited standards, with fall protection training under 1926.503 and ladders under 1926.1053 also in the top ten 1. That enforcement history matters at trial because it establishes that the hazard is universally recognized in the industry, which cuts against a defense premised on unforeseeability.
The legal framework is unusually concrete. In construction, 29 CFR 1926.501 requires that each employee on a walking or working surface with an unprotected side or edge six feet or more above a lower level be protected from falling, and imposes the same six-foot trigger for hoist areas, holes including skylights, excavation edges, and residential construction activities 2. The standard also carries a presumption that fall protection is feasible, which places the burden on the employer to demonstrate infeasibility before resorting to an alternative fall protection plan 2. In general industry, the parallel duty appears at 29 CFR 1910.28, with a four-foot trigger for most unprotected sides and edges 3.
The performance criteria in 29 CFR 1926.502 are where most technical disputes are actually resolved. Guardrail top rails must sit 42 inches plus or minus 3 inches above the walking level and withstand a 200-pound force applied within two inches of the top edge in any outward or downward direction 4. Personal fall arrest systems must limit maximum arresting force to 1,800 pounds when used with a body harness, limit free fall to no more than six feet and prevent contact with any lower level, and limit deceleration distance to 3.5 feet, with anchorages capable of supporting at least 5,000 pounds per employee attached unless designed by a qualified person as part of a complete system with a safety factor of at least two 4. Fall clearance calculation — lanyard length plus deceleration distance plus harness stretch plus worker height plus a safety margin — is a recurring point of failure in real incidents, because a compliant harness anchored too low will not stop a worker before he reaches the level below.
Training is a separate and independently actionable requirement. Under 29 CFR 1926.503, the employer must provide a training program conducted by a competent person covering the nature of fall hazards, correct erection and use of the systems in place, and the role of each employee in any fall protection plan, with written certification of the training and retraining when there is reason to believe the employee lacks the required understanding 5. Cases frequently turn on whether that certification exists, whether the training addressed the actual system in use rather than a generic overview, and whether a competent person was on site with the authority to correct hazards.
Above the OSHA floor sit the ANSI/ASSP Z359 fall protection and restraint standards, which address equipment design and testing, managed fall protection programs, anchorage connectors, self-retracting devices, and rescue 6. Those consensus standards are important in two ways: they often define what a reasonably prudent contractor or equipment manufacturer should have done where OSHA is silent, and they govern the design side of product cases involving harnesses, lanyards, self-retracting lifelines, horizontal lifeline systems, and anchor points. A complete fall case usually needs an expert who can move between the regulatory duty, the equipment engineering, the multi-employer worksite relationships among general contractor and subcontractors, and the rescue plan that should have existed for a worker left suspended after an arrested fall.
OSHA requires that a personal fall arrest system limit maximum arresting force to 1,800 pounds with a body harness, limit free fall to no more than six feet without contacting a lower level, cap deceleration distance at 3.5 feet, and be tied to an anchorage capable of supporting at least 5,000 pounds per attached employee.
Case Types
Falls from unprotected leading edges, floor openings, and roof perimeters where no guardrail, net, or arrest system was provided
Falls through skylights, roof holes, and unsecured covers
Personal fall arrest system failures involving anchorage adequacy, insufficient fall clearance, or improper connector and lanyard selection
Guardrail and safety net system deficiencies in height, strength, or installation
Inadequate fall protection plans, absence of a competent person, and missing or generic training certification under 1926.503
Product liability claims involving harnesses, lanyards, self-retracting lifelines, horizontal lifelines, and anchor connectors

FAQ
A qualified expert should hold a Professional Engineer license or Certified Safety Professional credential, or an equivalent safety engineering background, and should have served as a competent or qualified person for fall protection on active sites. Command of OSHA Subpart M and the ANSI/ASSP Z359 standards is essential, as is the ability to perform a fall clearance calculation and assess anchorage capacity rather than simply recite the regulation.
These experts are retained in falls from leading edges, roofs, and floor openings; skylight and roof-hole falls; personal fall arrest system failures; guardrail and safety net deficiencies; and training and fall protection plan claims. They also appear in product liability cases involving harnesses, lanyards, self-retracting lifelines, and anchor connectors, and in multi-employer worksite disputes over which contractor owed the duty.
In construction, 29 CFR 1926.501 sets a six-foot trigger for unprotected sides and edges, hoist areas, holes including skylights, excavation edges, and residential construction. In general industry, 29 CFR 1910.28 generally sets a four-foot trigger. The construction standard also carries a presumption that fall protection is feasible, so an employer relying on an alternative fall protection plan bears the burden of demonstrating that conventional systems were infeasible or created a greater hazard.
Most often because of clearance, not equipment failure. OSHA permits up to six feet of free fall and 3.5 feet of deceleration distance, and harness stretch and worker height add more; if the anchorage sits too low or the lanyard is too long, a fully compliant system will arrest the fall only after the worker has already struck the level below. Anchorage adequacy is the other recurring problem, since anchorages must support at least 5,000 pounds per attached employee unless engineered as part of a complete system.
Not by itself. Under 29 CFR 1926.503 the program must be conducted by a competent person and must cover the nature of the fall hazards in the work area, the correct erection and use of the systems actually in place, and each employee's role in the fall protection plan, with written certification and retraining where there is reason to believe the employee lacks the required understanding. A generic certificate that does not match the system the worker was actually using is a common weakness on both sides of these cases.
In general, expert fees are determined by the expert themselves, based on a variety of criteria. Among those criteria are professional experience, forensic and testimony experience, relevant certifications, case-type specialization, and publications. Vident does have some influence over expert fees by comparing experts within a specialty, but ultimately it is a personal decision by the expert.
