the toxicity of lead. Few workers, however, had still not

had not taken a bath and changed dresses after the work.
Occupational health education and training are fundamental
tools in the prevention of occupational diseases10), but one
occupational health education has the limit. Occupational
health education should be repeated at least every 6 months
or annually for workers.
To make occupational health education more sufficient,
collaboration of managers and/or supervisors with workers
should be continued. Adequate personal hygiene is also
emphasized11, 12). Annual intensive medical supervision is
also recommended for the exposed workers to prevent
occupational diseases13). Motivation program will be
effective to make job safety analysis spontaneously by
oneself14). Finally, we would like to emphasize that
occupational health education and collaboration may be more
important than engineering control of working environment
in the developing countries to reduce the risk of lead
poisoning in battery manufacturing plants
