Applied study and case report of comparison and application of two occupational health risk assessment methods in chair furniture manufacturing enterprises / 预防医学

ABSTRACT

Objective To apply and compare two occupational health risk assessment methods of Singapore occupational semi-quantitative risk assessment technique and occupational health risk assessment model provided by the International Council on Mining and Metal (ICMM) in chair furniture manufacturing enterprises. Methods Three chair furniture manufacturing enterprises were selected and investigated by occupational health. Singapore occupational semi-quantitative risk assessment technique and occupational health risk assessment model provided by the ICMM were used to evaluate the exposure risk in workers and compared. Results The result from the Singapore model indicated that there were extremely high risk for wood dust exposure at word-drilled workshop in factory C, high risk for wood dust exposure at word-drilled workshop in factory B and C, high risk for benzene exposure at glue-sprayed workshop in factory B and C, medium risk for wood dust exposure at wood-drilled workshop in factory A, toluene, xylene, dichloromethane, formaldehyde in factory B, toluene, xylene in factory C. There were inconsistent evaluation results using the ICMM tools of standard-based matrix and calculated risk rating. There were unacceptable risks for methylene chloride exposure at glue-sprayed workshop and word dust exposure at word-drilled workshop in factory A, B, C. There were unacceptable risks for benzene exposure at glue-sprayed workshop in factory B and C, toluene exposure at glue-sprayed workshop in factory A and C, ethyl acetate exposure at glue-sprayed workshop in factory B and C. The consistency of risk levels evaluated by Singapore occupational semi-quantitative risk assessment technique and rating evaluated mothod of risk assessment model provided by the ICMM was 58.33％ (weighted kappa value 0.25) . The consistencies of risk levels evaluated by Singapore occupational semi-quantitative risk assessment technique and risk assessment model provided by the ICMM were low (weighted kappa value 0.00) . Conclusion Singapore occupational semi-quantitative risk assessment technique and risk assessment model provided by the ICMM were both suitable for the chair furniture manufacturing enterprises, but the outcome of the two methods is inconsistent.
