[Objective] To analyze the occupational health and safety management conditions of the workers exposed to le ad in a flash memory manufacturer, to study and evaluate the effective ways and measures to prevent lead poisoning in the lead contamination manufacturers.

[Methods] We investigated the manufacturer's educational program for the occupational health, and the technical measures for occupational disease prevention taken by the manufacturer, and collected the annual test data of le ad smoke concentration in the soldering workshop. 122 workers exposed to lead in the soldering workshop underwent pre-job and on post occupational health examination from 2000 through 2008. Then we evaluated the health status of those exposed to lead, assessed the effect of health protection and lead poisoning prevention by measures of health promotion.

[Results] As a result of the management of occupational disease prevention and the implementation of a variety of occupational disease prevention measures by the manufacturer, the time-weighted average concentration (TWA) of the lead smoke in the soldering workshop was no longer greater than 0.001 mg/m3. The blood lead and blood zinc protoporphyrin values of those who underwent pre-job examination were in the normal range. The blood lead and blood zinc protoporphyrin values of the workers who had worked for 0.5 year to 5.5 years in the workshop showed a statistically different from their pre-job examination values. However, the workers still had no obvious symptoms and signs, and those values were within the normal range and with no clinical significance.

[Conclusion] Carrying out health promotion initiatively, establishing occupational health and safety management system, and taking measures such as staff training & education, raw materials & process methods optimization and improvement of facilities, environmental protection & personal protection, and monitoring, supervision etc., can effectively reduce lead hazard to workers. Therefore it is of important reference and guiding significance to the lead poisoning prevention efforts by the related enterprises. At the same time, even in low concentration cases, it is very imperative to keep surveillance on the occupational health of the workers exposed to lead.
