Résumé: | The framework of the present paper was to
evaluate the exposure to dust pollution and aerosols
of the polyurethanes foam intended for the thermal
insulation of refrigerators.
Based upon the worker`s complaints and investigations done in collaboration with occupational
physicians; four testing stations were set up to evaluate the air quality at the gates injection (GI), tanks
injection (TI), tank cleaning (TC), and the workshop
atmosphere (WA). Two sampling techniques were
used. The first was to use the rotary cup individual
sensor flow dust of 10 l/min (CIP 10), with three
fractions selectors; alveolar, thoracic and inhalable
to evaluate the weight concentration. The second
technique was using impregnated filters to sample
and analyze the identified aerosols.
For the samples taken in the (TC) station using
the (CIP10), the results have shown that the air in the
worker`s breathing area contains 2.6 mg/m3 for the
alveolar fraction, 1.33 mg/m3 for the thoracic fraction and 5.33 mg/m3 for the inhalable fractions. In
the (WA) station we have got 3.3 mg/m3 for the alveolar fraction; 8.6 mg/m3 for the thoracic fraction
and 7.33 mg/m3 for the inhalable fraction. The qualitative analysis of the aerosols through the filter sampling has confirmed the presence of the 4,4-Methylene diphenyl diisocyanate (4,4-MDI) in the workshop atmosphere.
This research confirmed through the obtained
results that operators are exposed permanently during their working hours to both pollutions dust and
aerosols of 4,4-MDI |
