Title Case study - Airborne hexamethylene diisocyanate and particulate matter exposures during fire/rescue ladder finishing operations
Bibliographic information Mar. 2006, Vol.3, No.3, p.D28-D32. 11 ref.
Abstract In 2004, the National Institute for Occupational Safety and Health (NIOSH) received a request from the management of a steel ladder fabrication plant to evaluate employee exposures to hexamethylene diisocyanate (HDI) during spray painting operations. Management representatives were also concerned about exposures to particulate matter and crystalline silica during spray painting and sanding operations. Personal breathing zone and general area samples were collected and analysed. Findings are discussed. All samples were within the NIOSH and ACGIH threshold limit values, although some exceeded the United Kingdom HSE limit values. Particulate matter was well within limits and crystalline silica was not detected. Recommendations were made for further reduction of exposures to HDI.
