Preventing falls: Choosing compatible Fall Protection Supplementary Devices (FPSD) for bridge maintenance work using virtual prototyping
Apart from struck-by safety incidents, fall-related injuries are a major concern in bridge maintenance work. To protect against falls from bridge decks, maintenance workers largely rely on existing bridge guardrails. However, a large number of bridge guardrails do not comply with the regulatory height requirement of 42 ± 3 in. for sufficient fall protection – although appropriate for vehicular traffic. To address this fall protection issue, a few departments of transportation (DOTs) have adopted Fall Protection Supplementary Devices (FPSDs). These devices are temporarily installed...

A Pilot Study of Nanoparticle Levels and Field Evaluation of N95 Filtering Facepiece Respirators on Construction Sites
Little attention has been paid to the generated submicron ultrafine and nanoparticles and their exposure levels on construction jobsites. This information is needed because cytotoxicity of nanoparticles is well known now. In addition, the performance of particulate respirators generally used by construction workers has never been evaluated in field conditions against ultrafine and nano-sized particles. We hypothesized that workers on construction jobsites are exposed to high levels of nanoparticles and current NIOSH-recommended N95 respirators may not provide them adequate protection against aerosolized...

The purpose of this article is to present developed new ergonomic modular cold protective clothing, which allows for easy adaptation of the thermal insulation of clothing to a worker's individual needs. This clothing was compared in a laboratory study with the clothing having so far been used by workers in a cold environment using physiological and physical measurements...
Predictive multiscale computational model of shoe-floor coefficient of friction
Understanding the frictional interactions between the shoe and floor during walking is critical to prevention of slips and falls, particularly when contaminants are present. A multiscale finite element model of shoe-floor-contaminant friction was developed that takes into account the surface and material characteristics of the shoe and flooring in microscopic and macroscopic scales. The model calculates shoe-floor coefficient of friction (COF) in boundary lubrication regime where effects of adhesion friction and hydrodynamic pressures are negligible. The validity of model outputs was assessed by...
