Oil mist particles emitted in industrial buildings are harmful to health. To evaluate the control effect of existing ventilation strategies on oil particles, this work conducts field investigations processing workshops different scales and processes. Through on-site measurements, basic characteristics mass concentration, quantity particle size distribution, technology, emission rate can be lear...

Background: Weaning from mechanical ventilation in the intensive care unit is an important step in the treatment process. More patients in less than 6 hours after cardiac surgery can be separated from mechanical ventilation and extubated. However, 20-40% of patients after cardiac surgery, due to dysfunctional ventilator weaning response (DVWR), still remain under mechanical ventilation. Therefo...

background and objective : a considerable amount of sulfur hexafluoride is applied to evaluate the performance of each laboratory hood according to ashrae–110-95 method. sf 6 is extremely hostile to environment and expensive. in present work, the possibility of conducting this method of hood performance test with less volume of sf 6 was investigated. material and methods : the performance of a ...

OBJECTIVES CO poisoning has been a serious industrial hazard in Japanese workplaces. Although incomplete combustion is the major cause of CO generation, there is a risk of CO poisoning during some welding operations. The aim of the present study was to evaluate the generation rate of CO from CO2 arc welding under controlled laboratory conditions and estimate the ventilation requirements for the...

1. Abstract The only large-scale cost-effective way to exhaust contaminated air from the furnace pot room of an industrial plant is through natural ventilation. The effectiveness of the ventilation depends, amongst others, on the openings of the windows through which the air is allowed to enter and exit the workshop. The ventilation is also directly influenced by the prevailing weather outside ...

The lung function impairment is the most common respiratory problem in industrial plants and their vicinity. Therefore, the purpose was to study the affects of wood dust and its duration of exposure on lung function. This was a matched cross-sectional study of Spirometry in 46 non-smoking wood workers with age range 20 - 60 years, who worked without the benefit of wood dust control ventilation ...
