J2 Engineering provides a full range of investigation, testing and analysis in the area of slip, trip and fall accidents. Our slip and fall investigations include an evaluation of the walking surface, the effect of the presence of any contaminants and the nature and condition of the shoe sole material. We conduct scene testing to determine the slip resistance of walkway materials and walkway surfaces as they are utilized under differing conditions. When testing a walkway surface, we use ASTM approved test equipment and procedures, as well as protocols developed during ASTM sponsored research.

J2 Engineering has worked with major shoe manufacturers in the development, testing and analysis of tread patterns and shoe soling materials. We have completed testing for tile and under-floor lighting manufacturers in the evaluation of glazing types and patterns. J2 Engineering also consults with the manufacturers of decking in the analysis of the slip resistant properties of composite materials and wood patterns.

J2 Engineering is involved in state of the art research in walkway safety and the development of national standards for the analysis of slip resistance. As members of ASTM International Committee F-13 (Safety and Traction for Footwear), we investigate the relationship between utilized and required friction and work to develop standards for the measurement of walkway slip resistance. As members of the Research Subcommittee of F-13, we help design and direct research in fall protection.

As a Collaborative Researcher at the Musculoskeletal Biomechanics Research Laboratory of the University of Southern California, we investigate gait biomechanics with respect to slip and fall, and evaluate the biofidelity of slip meters.

J2 Engineering also inspects walkways and stairways for the presence of hazards including discontinuities and deficiencies in illumination which can lead to a slip/trip and fall. Stairs and walkways are evaluated for compliance with the appropriate building codes, Life Safety Codes and ASTM and ANSI standards. Walkway safety and facilities access are examined for compliance with the American’s with Disabilities Act (ADA).
