This study reviewed all work-related burn injuries within the period 1 April 1992 to 31 March 1993 for the purpose of establishing data on occupational burns in Singapore to identify the specific at-risk population and formulate prevention strategies. All 163 patients who were admitted to the Burns Centre, Singapore General Hospital, as a result of burns suffered in the workplace were reviewed using the World Health Organisation Burns Data Protocol. Burns data recorded included demography, industrial sector involved, aetiology, extent of injury and eventual outcome in terms of mortality and morbidity. Occupational burns accounted for 45% of all admissions to the Burns Centre. Male workers in the 20 to 40-year age group predominated with 90% of admissions. The most common aetiology was flame burns and explosions (52.8%) followed by scalds (24.5%) and electrical (10.4%), chemical (6.1%) and contact (6.1%) burns. The average body surface area (BSA) involved was 8% (range 0.25% to 90%). Twenty-seven patients suffered full-thickness burns and the average area of involvement was 2% (range 0.25% to 90%). The most common anatomical regions involved were the upper limbs (46.3%) followed by lower limbs (31.9%). Eighteen patients (11.0%) sustained major burns requiring fluid resuscitation and 39 patients (23.9%) sustained respiratory burns. Seven patients died, giving a mortality rate of 4.3%. The average BSA for these patients was 46.4% and all had respiratory burns. In all, occupational burns accounted for 2011 patient-days of hospitalization, 630,637 lost days at work and inpatient treatment costs amounting to S $1.32 million.(ABSTRACT TRUNCATED AT 250 WORDS)
