Personal exposure to wood dust among workers in NekaChoob factory in 2013

Background and Purpose: Inhalation of hardwood dust may produce a range of adverse health effects in the upper and lower respiratory system, including asthma, along with Sino-nasal cancer and nasopharyngeal cancer. This study was carried out to evaluate personal exposure to wood dust among workers in chipboard and furniture production saloons in Neka Choob factory, Iran. Materials and Methods: Gravimetric method No. 0500 recommended by National Institute for Occupational Safety and Health was used to determine the wood dust concentrations in the workers’ breathing zone. The sampling air was drawn through a polyvinyl chloride filter within the breathing zone, using a calibrated personal sampling pump. Results: The mean workers’ personal exposure to wood dust in furniture production saloon (2.87 ± 1.95 mgm-3) was higher than mean exposure of workers whom were working in chipboard saloon (0.93 ± 0.35 mgm-3). The mean workers’ exposure to wood dust for both saloons was 1.70 ± 1.53 mgm-3. Conclusion: The mean workers’ personal exposure to wood dust in Neka Choob factory was higher than Occupational Exposure Limit (OEL) recommended by national (Iranian Committee for Review and Collection of OEL) and European ::union:: Scientific Committee on OEL committees. All workers in furniture production saloon and three workers in chipboard saloon have a mean exposure higher than OEL.
