BACKGROUND Many unintentional injuries that occur in and around the home can be prevented through the use of safety equipment and by consistently following existing safety recommendations. Unfortunately, uptake of these safety behaviors is unacceptably low. This paper describes the design of the Make Safe Happen® smartphone application evaluation study, which aims to evaluate a mobile technolog...

AIMS AND OBJECTIVES To identify and compare hearing protection interventions for youth working and living on farms. BACKGROUND Noise-induced hearing loss represents a significant risk factor for injury, disability and death in agricultural populations due to an inability to receive sensory information that can indicate dangerous situations. Despite the availability of hearing protection devic...

OBJECTIVE The purpose of this study was to examine diffusion of and predictors of helmet use among skiers and snowboarders in the Western United States and Canada. DESIGN 6400 skiers and snowboarders at 29 ski resorts in the Western United States and Canada were interviewed on chair lifts and observed for helmet use during two consecutive ski seasons (winters 2001 and 2002). SETTING Skiers ...

The British Standards Institution 'Guide to implementing an effective respiratory protective device programme' (BS 4275) lists assigned protection factors (APFs) for various types of respiratory protective equipment (RPE). The APFs were allocated either on the basis of available workplace studies data which met set criteria or on the basis of professional judgement that there is equivalence bet...

The basic aim of this research was to establish the efficiency of filtering materials widely used in respiratory protection devices with particular interest in their porosity, degree of electric and changeable process parameters, such as the flow rate of the test nanoaerosol and the size range of nanoparticles. Tests were carried out with an NaCl solid aerosol of 3.2 × 105 particles/cm3 for the...

Thyroid hormone has pleiotropic effects on cochlear development, and genomic variation influences the severity of associated hearing deficits. DW/J-Pou1f1dw/dw mutant mice lack pituitary thyrotropin, which causes severe thyroid hormone deficiency and profound hearing impairment. To assess the genetic complexity of protective effects on hypothyroidism-induced hearing impairment, an F1 intercross...

background: there are inconsistencies about the effects of farmworker housing and workplace conditions and use of self-protective behavior practices and personal protective equipment (ppe). objective: to investigate the association between workplace and housing conditions and farmworker use of pesticide safety practices and ppe. methods: this study was conducted in 4 counties in north carolina,...

aim: the purpose of this study was to compare the difference in the output intensity of light emitting diode (led) light cure (lc) devices with and without a protective sleeve and its clinical significance.  materials and methods: the output intensity of 152 lc units in dental offices across the state of odisha were examined. the collection of related information included an average number of e...
