| Summary: | The preliminary measurement of welding fumes
was conducted by means to get firsthand experience and
understanding the welding fumes issues in automotive assembly
plant in Malaysia. Personal sampling pumps were provided to a
human welder of highest risk in the assembly section. Series of
direct reading measurement for area sampling of particulate
matters 2.5μm or less in diameter size (P.M 2.5), toxic gases and
temperature were also conducted at the same time. The welding
fumes sample were then analyze by scanning electron
microscope with energy dispersive spectroscopy (SEM-EDS).
Questionnaires were distributed to the welders for
questionnaire’s pilot test purpose in order to determine
welder’s knowledge on welding hazards and persistent
symptom experience by each welder. Results of the study show
that welding fumes contains the highest element of cobalt and
nickel. Carbon monoxide (CO), carbon dioxide (CO2) and
ammonia level were well below the standard level. Results
from the mean score questionnaire analysis shows the welders
posses limited knowledge of welding fumes hazard and not sure
of the health effects of welding fumes There are eight persistent
symptoms that had been experience by at least 50% of the
welder. This preliminary study had successfully identified
suggestion and alteration towards the actual measurement that
will be conduct on the next stage. |
