OBJECTIVES This article presented four anthropometric theories (univariate, bivariate/probability distribution, multivariate, and shape-based methods) for protective equipment design decisions. BACKGROUND While the significance of anthropometric information for product design is well recognized, designers continue to face challenges in selecting efficient anthropometric data processing method...
In this study a composite of activated carbon and carbon nanofiber (AC/CNF) was prepared to improve the performance of activated carbon (AC) for adsorption of volatile organic compounds (VOCs) and its utilization for respirator cartridges. Activated carbon was impregnated with a nickel nitrate catalyst precursor and carbon nanofibers (CNF) were deposited directly on the AC surface using catalyt...
Evaluation of a pandemic preparedness training intervention of emergency medical services personnel.
INTRODUCTION Emergency medical services (EMS) personnel play an integral role during the national response to a pandemic event. To help ensure their health and safety, especially during the early stages of an outbreak, knowledge and adherence with personal protective equipment (PPE) and infection control strategies will be essential. OBJECTIVES The objective of this study was to assess the ef...
A three phase laboratory and clinical evaluation of a new fluidically controlled volume ventilator (Ohio 550) was undertaken to determine if this more compact, less complex and less costly unit retained the multiple advantages which have been established for volume ventilators in the continuous ventilatory support of patients in respiratory failure. Inspired volume, peak pressure, and flow rate...
Commercially available controls for reducing worker exposure to paint overspray were evaluated in six autobody shops and a spray-painting equipment manufacturer's test facility. Engineering control measures included spray-painting booths, vehicle preparation stations, and spray-painting guns. The controls were evaluated by measuring particulate overspray concentrations in the worker's breathing...
Environmental and biological monitoring of lead, cadmium and chromium levels in spray painters is reported. All of the study subjects worked in automobile body repair shops that had no standard spraying room. They were divided into 2 groups, those who wore an aerosol-removing respirator while spraying (n=20) and those who did not wear the respirator (n=50). Air in the breathing zone of each sub...
The results are reported of domiciliary cuirass respirator treatment, using tailor-made shells, in four patients with severe thoracic scoliosis. Three of the patients had suffered from poliomyelitis. All complained of increasing dyspnoea on exertion, ultimately interfering with almost every activity of daily life; three patients had severe acute respiratory failure necessitating urgent admissio...
