New AIHA Fact Sheets: Respiratory Protection for Health Care Workers, General Public

The AIHA Respiratory Protection Committee recently developed fact sheets on respiratory protection for reducing disease transmission among health care workers and the general public. Health care workers in particular can be exposed to a variety of infectious agents while performing their duties, and respirators are frequently used to provide protection from exposure to these airborne infectious agents.

Ladder Safety: There’s an App for That

NIOSH recently released its first smart phone application (app) for mobile devices. This free app is aimed at improving extension ladder safety by providing real-time safety information delivered via the latest technology. Falls are a persistent source of injury in many occupations and in home use. Falls are the number one cause of construction-worker fatalities with falls from ladders a common yet preventable construction injury. Health services and the wholesale and retail industries experience the largest number of non-fatal fall-related injuries. Ladders are also used in home maintenance and repair and to access higher places at home.
Misjudging the ladder angle is a significant risk factor for a fall. If the ladder is set too steeply, it is more likely to fall back or slide away during use, and if it is set too shallow then the bottom can slide out. The NIOSH Ladder Safety phone app has an angle of inclination indicator which uses visual and audible signals making it easier for workers and other users to set an extension ladder at the proper angle of 75.5 degrees. The app can help workers prevent falls and is also a tool for employers who want to ensure a safe workplace. The app is available through the NIOSH website, the Apple App-store, and Android Apps on Google Play.

Cold protective clothing with reflective nano-fibrous interlayers for improved comfort

Purpose - The purpose of this paper is to develop multi-layer clothing assemblies consisting of fibrous battings and reflective nano-fibrous thin layers for cold protective clothing for improved thermal insulation. Design/methodology/approach - Thermal insulation values of totally twenty assemblies made of varying layers of a thick polyester batting and four different types of thin interlayers were measured using a guarded hot-plate to investigate the effect of the properties of thin interlayers and construction of multi-layer assemblies on thermal insulation. Cold protective jackets filled with polyester battings sandwiched with or without interlayers were also made and tested on the sweating fabric manikin-Walter. Findings - Results show that the Rosseland mean extinction coefficients of the thin interlayer and the associated radiative thermal conductivity of the interlayers have significant influence on thermal insulation of the assembly when more than one reflective nano-fibrous interlayers are sandwiched in the assembly. The cold protective jacket filled with multilayer polyester battings and reflective nano-fibrous interlayers have better thermal insulation and moisture permeability index (im) than those filled with the same multilayer polyester battings, but with non-reflective nonwoven interlayers or without interlayers. Originality/value - This paper clearly demonstrates the advantages of reflective nano-fibrous thin material for interlayers in the cold projective jacket.
