In the course of evaluating industrial heat exposures, three very hot environments having heat stress indices over 300 have been analysed by the techniques of Haines and Hatch (1952) and Belding and Hatch (1955). In addition, pulse and oral temperature measurements were made on three subjects exposed to these environments. These studies indicate that the methods of Haines and Hatch and Belding ...

BACKGROUND Methylene bis(thiocyanate) (MBT) is a microbiocidal agent mainly used in industrial water cooling systems and paper mills as an inhibitor of algae, fungi, and bacteria. CASE PRESENTATION We describe the first case of severe intoxication following inhalation of powder in an industrial worker. Profound cyanosis and respiratory failure caused by severe methemoglobinemia developed with...

modeling of relationship between ventilation rate of buildings and sick building syndrome symptoms hosseinpoor s , gholamiborujeni f *, mohammadian y received: 22 aug, 2013 accepted: 23 oct , 2013 abstract background & aims: indoor air pollution with microbilal, chemical and physical pollutants lead to sick building syndrome (sbs). suitable ventilation of buildings, is one of the best methods t...

Chlorine is a common agent found worldwide in industrial and household applications. This element is found everywhere and anywhere around the globe. Because of its ubiquitous nature in the world, chlorine-injured patients may be expected at all medical facilities, from large-urban to small-community to austere-tent facilities. Chlorine has been used as a chemical weapon since 1915 and has been ...

Suspension-feeding fishes such as goldfish and whale sharks retain prey without clogging their oral filters, whereas clogging is a major expense in industrial crossflow filtration of beer, dairy foods and biotechnology products. Fishes' abilities to retain particles that are smaller than the pore size of the gill-raker filter, including extraction of particles despite large holes in the filter,...

When storing sugar beets in natural conditions, transformations of the chemical composition occur it, leading to accumulation non-sugars, which reduces processing efficiency and yield. The use technology forced ventilation air environment kagats is aimed at reducing negative impact ongoing processes. This study presents results changes technological properties during industrial storage two type...

welders may suffer from welding fumes generated during the process if the ventilation systems are improperly applied. the objective of the present work was to study the mitigation of air pollutants at welding stations, using different ventilation scenarios. four air pollutants including iron oxide, respirable dust, ozone, and carbon monoxide were measured during four different ventilation scena...

abstract background: occupational exposure studies indicate that formaldehyde exposure causes temporary and consistent effects on industrial workers exposed to formalin. case: the case was a 36-year-old man who had developed intravascular hemolytic anemia caused by formalin after inhalation exposure. formalin is a clear solution of 37% formaldehyde in water. the primary route of exposure to for...
