Introduction: Despite the advances in occupational safety, many accidents occur in the workplace. The most of these accidents caused by poor workers safety performance. Knowing the factors that affect safety performance is a suitable guide to planning for occupational accident prevention. This study was conducted to assess workers safety performance and determine its associated demographic fact...

In the event of an emergency due to a fire or other crisis, a necessary but time consuming pre-requisite, that could delay the real rescue operation, is to establish whether the ground or area can be entered safely by human emergency workers. The objective of the VIEW-FINDER project is to develop robots which have the primary task of gathering data. The robots are equipped with sensors that det...

Changes in ventilatory capacity during the work shift were studied in workers exposed to tea dust in tea-packing plants, wood dust in two furniture factories, and virtually no dust in an inoperational power station. The FEV1 and FVC in workers exposed to dust were found to decline during the work shift by a small but significant volume. The MMFR, Vmax 50% and Vmax 75% were to variable to displa...

BACKGROUND U.S. natural gas production increased 40% from 2000 to 2015. This growth is largely related to technological advances in horizontal drilling and high-volume hydraulic fracturing. Environmental exposures upon impacted communities are a significant public health concern. Noise associated with natural gas compressor stations has been identified as a major concern for nearby residents, t...

Introduction: Gasoline is a complex mixture of more than 500 various hydrocarbons. The elimination of lead from petrol has been associated with the production of significant amounts of hepatotoxic and nephrotoxic monocyclic aromatic hydrocarbons such as benzene, toluene and xylene (BTX). The main purpose of this study was to ascertain whether or not exposure to unleaded petrol, under normal wor...

We study the problem of dynamically allocating flexible workers to stations in tandem or serial manufacturing systems. Workers are trained to do a subset of consecutive tasks. We show that the optimal policy is often LBFS (last buffer first-served) or FBFS (first buffer first-served). These results generalize earlier results on the optimality of the pickand-run, expedite, and bucket brigade-typ...

Consider a production system that consists of m assembly stations arranged in series. All jobs enter the assembly line at station 1 and proceed with subsequent stations in the same order as in a ßow shop. Each job spends a Þxed amount of time c in each station, known as the production cycle. This production system is synchronous or paced because jobs move one station forward synchronously, ever...
