spreading wood particles and attached colored materials in work places can cause many problems for woodwork industry workers. the aim of this study is to design and implement a local exhaust ventilation system to control wood dust and isocyanates simultaneously. the study was conducted on 18 workers in the paint workroom of a wood door industry. at first, an overview of the workplace indoor air...

According to the Machinery Directive 2006/42/EC, one of the essential requirements relating to occupational safety and health hazards is to prevent dust pollution emitted by machinery during the implementation processes. Research on evaluation of emissions from machinery, according to the method of test bench using tracer gases, are currently being conducted in CIOP-PIB. This article presents s...

and Implications Odor control for swine facilities has focussed on storage and the land application phases of manure handling. A third component, ventilation exhaust air, has received little attention. This research was targeted at reducing odor emitted from ventilation exhaust air by filtering odor carrying dust particles. The ultimate objective is to develop a system that could be implemented...

A method of determining dust emission and efficiency of its removal by means of local exhaust ventilation from machinery has been described. It complies with Standard No. EN 1093-3:1996 (European Committee for Standardization, 1996) and consists in determining air pollution concentrations in the measurement duct used for air removal from the chamber incorporating devices to be tested. The air v...

The present thesis aims to study the effect of human movements on local exhaust ventilation. In its simplest terms, local exhaust ventilation is a system which has the function of extracting contaminated air situated close to the contaminant source, protecting a working person from exposure to hazardous substances by containing or capturing them locally, at the emission point. As an important s...

Inadequately performed hand hygiene and non-disinfected surfaces are two reasons why the keys and mouse-buttons of laptops could be sources of microbial contamination resulting consequently in indirect transmission of potential pathogens and nosocomial infections. Until now the question has not been addressed whether the ventilation-blowers in laptops are actually responsible for the spreading ...

Because of the need to safely vent exhaust gases, most engine dynamometer facilities are not well suited to measuring engine exhaust orifice noise. Depending on the location of the dyno facility within the building, the exhaust system may need to be extended in order to properly vent the exhaust fumes. This additional ducting changes the acoustic modes of the exhaust system which will change th...
