background: for its toxicity, benzene exposure is one of the main health concerns for high risk occupations like gasoline station workers. however, there is little knowledge about the effect of benzene metabolites on hematological parameters. objective: to evaluate the correlation between the urinary level of trans, trans-muconic acid (t, t-ma), a benzene metabolite, and some hematological para...

BACKGROUND The present study was conducted to investigate the probable changes in blood pressure of workers in coal mines. METHODS In this study 91 workers, who worked in forwarding, preparation and exploitation units of coal mines and were in direct contact with carbon dioxide gas (from fireworks), have been selected as the case group, and 70 workers, who did not have direct contact with thi...

During 2003-2010, the U.S. oil and gas extraction industry (onshore and offshore, combined) had a collective fatality rate seven times higher than for all U.S. workers (27.1 versus 3.8 deaths per 100,000 workers). The 11 lives lost in the 2010 Deepwater Horizon explosion provide a reminder of the hazards involved in offshore drilling. To identify risk factors to offshore oil and gas extraction ...

Robot automation systems are rapidly taking the place of the human work force. One of the benefits is that this change provides the human work force with the time to spend on more creative tasks. The highest population of robots is in spot welding, spray painting, material handling, and arc welding. Spot welding and spray painting applications are mostly in the automotive industry. However, arc...

LPG storage tanks may be seriously threatened by a fire coming from nearby fuels or leakage appearance. The aim of the study was to prepare three-dimensional model release on car gas station under different environmental conditions. CFD simulations liquid and phase tank localized performed. First, ALOHA software applied determine mass flow rate, while Ansys used shape size hazardous zone. To re...

Santa likes to run a lean and efficient toy-making operation. He also likes to keep up with the latest math developments. So naturally, when Santa was building a new factory a few years back, he designed an interesting factory and method for assigning workers to toys that was based on a recent article he read in the Monthly ??. Here were some of Santa’s constraints. As it turns out, each toy re...

Introduction: Occupational nature, strenuous physical activity, shift work, spatial and geographical location, as well as support facilities and equipment, pose greater risks to individuals in the oil and gas industry, especially those engaged in offshore oil exploration and production activities. The purpose of this article is to explain the issue of health and well-being of oil and gas indust...
