Eye problems among the workers in re-rolling mill exposed to high temperature

The aim of the study was to find out the eye problems of the workers exposed to high temperature in re-rolling mill.

A cross sectional study was conducted among 200 workers of selected re-rolling mills in Chittagong of Bangladesh during April to June 2008.

Data was collected through face to face interview of the respondents by using a pre tested questionnaire and check list and physical examinations which were completed by Braun Thermo Scan Ear Thermometer and by Coaxial-plus Ophthalmoscope. Work place temperature and humidity were measured by industrial digital thermometer and hygrometer.

Physical examination revealed that 25.5% of participants had inflammation of conjunctiva, 26% had itching of the eyes, 1.5% had corneal inflammation, 13.5% had partial opacity of the cornea, and 20.5% had hazy corneas. Of the total respondents, a majority had redness of the eyes, itching and blurring of vision. Most of the complaints were found to be associated with longer job duration (≥ 5 years), production workers and high temperature (≥ 40°C).

The current study findings recommended that, the workers should be protected by using safety glasses with side shields and by wearing an apron of impervious cloth. There should be a surveillance system on work environments by appropriate authority for monitoring safety and maintenance of industrial hygiene.
