Title Morbidity patterns among employees at a petroleum refinery
Bibliographic information Oct. 1991, Vol.33, No.10, p.1076-1080. 11 ref.
Abstract The morbidity experience of a prospective cohort of 2132 petroleum refinery workers (working from 1981 to 1988) was studied. Standardised morbidity ratios (SMRs) of disease prevalence were calculated using data from all manufacturing employees of the company as an internal comparison group. Morbidity for all causes combined was virtually the same as that for the comparison group with 2,311 observed and 2,318 expected disease prevalence events. However, there was a statistically increased prevalence of musculoskeletal system disorders (SMR=136) and of injuries (SMR=125) among staff employees and of skin and subcutaneous tissue disorders (SMR=138) among production employees. A review of the original morbidity reports for these skin conditions showed that none were due to exposure to chemical products or solvents. The SMR for neoplasms of the lymphatic and haematopoietic tissue among production employees was slightly elevated but was based on only 3 cases. Of the 3 cases, none was due to leukaemia.
