Stair Fall Analysis – Nationwide Expert Witness for Stairway Safety and Liability

Nationwide Expert Witness for Stairway Safety and Liability

Stairways are among the most common locations for slip and fall accidents, and also among the most complex. Our nationwide team of Slip and Fall Expert Witnesses investigates stairway design, construction, lighting, and maintenance to determine how and why an incident occurred. Using scientific analysis and industry standards, we identify whether the stairway met safety codes and maintenance expectations at the time of the fall.

Understanding Stairway Incidents Through Forensic Analysis

Stair fall incidents usually result from a combination of multiple contributing factors, including stair geometry, surface traction, lighting, and handrail placement. When one or more of these elements is out of compliance, the risk of a fall increases dramatically. Our forensic investigations combine measurements, visual documentation, and code comparison to clarify the cause of each event.

Comprehensive Stair Case Investigation

Each stairway investigation begins with a full site inspection, documenting every relevant aspect of the stairs, including riser height, tread depth, surface traction, and lighting. We assess compliance with ADA, IBC, and OSHA standards and identify design or maintenance deviations that could have contributed to the incident. Our goal is to determine if the stairway provided reasonable safety for use and whether property management fulfilled their duty of care.

Common Stairway Factors Evaluated:

• Uneven riser heights or tread depths
• Inconsistent lighting or poor visibility
• Missing or improperly installed handrails
• Slippery surface coatings or finishes
• Excessive slope or irregular stair geometry

Standards, Codes, and Accepted Practices

Our evaluations reference applicable safety standards such as the International Building Code (IBC), ADA Accessibility Guidelines (ADAAG), ASTM F1637 for safe walking surfaces, and ANSI A117.1 accessibility standards. These references establish objective benchmarks to determine whether the stairway design or maintenance met accepted safety expectations.

Forensic Methodology and Evidence Documentation

Our experts document each step of the investigation with calibrated measurement tools and high resolution photography. This data forms the basis of our forensic reports, which detail the geometric and environmental characteristics of the stairway. When appropriate, we perform surface traction tests to assess slip resistance, using ASTM and ANSI testing procedures to quantify the coefficient of friction (COF).

All findings are organized into a structured report that attorneys can rely on for depositions, mediation, or courtroom presentation.

Lighting and Visibility in Stairway Falls

Poor lighting often plays a significant role in stair related falls. Inadequate illumination can obscure tread edges, distort depth perception, or cause glare that prevents proper hazard recognition. Using calibrated light meters, we measure foot candle illumination and compare results to IES and OSHA standards. These measurements determine whether lighting conditions contributed to unsafe navigation of the stairway.

Human Factors and Biomechanics in Stair Falls

Understanding how human perception, movement, and behavior interact with stair design is critical in forensic analysis. Our experts evaluate how visibility, balance, gait, and step timing may have influenced the fall. We also consider environmental factors such as footwear, handrail use, and distractions. These findings help attorneys explain the human and mechanical dynamics of the incident.

Expert Testimony and Litigation Support

Our nationwide experts prepare evidence based testimony that translates technical findings into clear, persuasive explanations for judges and juries. We address how stairway design, lighting, maintenance, or construction defects contributed to the fall, and whether those conditions represented foreseeable hazards under the property owner’s duty of care.
