Differences in Safety Climate Perception by Health Care Worker, Work Schedule, and Workplace Characteristics.

Safety climate has been associated with patient and health care worker safety and outcomes. However, few studies have examined how perceptions of workplace safety differ by worker, work schedule, and workplace characteristics. Data from 10 168 participants in the National Institute for Occupational Safety and Health's Health and Safety Practices Survey of Healthcare Workers were analyzed.

Advancing Well-Being Through Total Worker Health®.

Total Worker Health® (TWH) is a paradigm-shifting approach to safety, health, and well-being in the workplace. It is defined as policies, programs, and practices that integrate protection from work-related safety and health hazards with promotion of injury and illness prevention efforts to advance worker well-being. The most current TWH concepts are presented, including a description of issues relevant to TWH and introduction of a hierarchy of controls applied to TWH.

Finite element simulations of the head-brain responses to the top impacts of a construction helmet: Effects of the neck and body mass.

Traumatic brain injuries are among the most common severely disabling injuries in the United States. Construction helmets are considered essential personal protective equipment for reducing traumatic brain injury risks at work sites. In this study, we proposed a practical finite element modeling approach that would be suitable for engineers to optimize construction helmet design.

Direct-on-Filter α-Quartz Estimation in Respirable Coal Mine Dust Using Transmission Fourier Transform Infrared Spectrometry and Partial Least Squares Regression.

In order to help reduce silicosis in miners, the National Institute for Occupational Health and Safety (NIOSH) is developing field-portable methods for measuring airborne respirable crystalline silica (RCS), specifically the polymorph α-quartz, in mine dusts. In this study we demonstrate the feasibility of end-of-shift measurement of α-quartz using a direct-on-filter (DoF) method to analyze coal mine dust samples deposited onto polyvinyl chloride filters. The DoF method is potentially amenable for on-site analyses, but deviates from the current regulatory determination of RCS for coal mines by eliminating two sample preparation steps: ashing the sampling filter and redepositing the ash prior to quantification by Fourier transform infrared (FT-IR) spectrometry.

The Perils of Integrating Wellness and Safety and Health and the Possibility of a Worker-Oriented Alternative.

In response to the article by Michael B. Lax, MD entitled "The perils of integrating wellness and safety and health and the possibility of a worker-oriented alternative," the National Institute for Occupational Safety and Health (NIOSH) provides updated information on the current focus and priorities and addresses concerns raised regarding the Total Worker Health® initiative. Many of the concerns and criticisms in the report echo those NIOSH publicly shares on a regular basis.

Emissions from a Diesel Engine using Fe-based Fuel Additives and a Sintered Metal Filtration System.

A series of laboratory tests were conducted to assess the effects of Fe-containing fuel additives on aerosols emitted by a diesel engine retrofitted with a sintered metal filter (SMF) system. Emission measurements performed upstream and downstream of the SMF system were compared, for cases when the engine was fueled with neat ultralow sulfur diesel (ULSD) and with ULSD treated with two formulations of additives containing Fe-based catalysts. The effects were assessed for four steady-state engine operating conditions and one transient cycle.

Measurement of mass-based carbon nanotube penetration through filtering facepiece respirator filtering media.

Recent studies suggest that a wide range of human health effects could result from exposure to carbon nanotubes (CNTs). A National Institute for Occupational Safety and Health survey of the carbonaceous nanomaterial industry found that 77% of the companies used respiratory protection, such as filtering facepiece respirators (FFRs). Despite CNT studies in some occupational settings being reported, the literature for mass-based penetration of CNTs through FFRs is lacking.
