Inventory of the chemicals and the exposure of the workers' skin to these at two leather factories in Indonesia

PURPOSE

Tannery workers are exposed to hazardous chemicals. Tannery work is outsourced to newly industrialized countries (NICs) where attention into occupational health hazards is limited. In this study, we investigated the skin exposure to hazardous chemicals in tannery workers and determined the prevalence of occupational skin diseases (OSDs) at tanneries in a NIC.

METHODS

A cross-sectional study on the observation of the working process and an inventory and risk assessment of the chemicals used. Classification of chemicals as potential sensitizers/irritants and a qualitative assessment of exposure to these chemicals. Workers were examined and interviewed using Nordic Occupational Skin Questionnaire-2002/LONG.

RESULTS

The risk of OSDs at the investigated tanneries was mainly related to the exposure of the workers' skin to chemicals in hot and humid environmental conditions. In 472 workers, 12% reported a current OSD and 9% reported a history of OSD. In 10% of all cases, an OSD was confirmed by a dermatologist and 7.4% had an occupational contact dermatitis (OCD). We observed that personal protective equipment (PPE) used was mainly because of skin problems in the past and not as a primary protection against OSD.

CONCLUSION

We observed a high frequency and prolonged exposure to many skin hazardous factors in tannery work although PPE was relatively easily available and which was generally used as a secondary preventative measure. The observed point-prevalence in this study was at the same level as that reported for other high-risk OSDs in Western countries and other tanneries in NICs. However, the observed point-prevalence in this study was lower than that reported in India and Korea. The results of our study and those of other studies at tanneries from other NICs were probably influenced by Healthy Worker Survivor Effect (HWSE).

Health and safety in the Lesotho Highlands Dam and Tunnel Construction Program

To review health and safety practices and to determine the occupational health status of dam workers in the Lesotho Highlands, a health and safety audit and a health study of 258 workers was undertaken. The workers were administered respiratory health questionnaires and underwent chest x-rays and lung function and audiometric testing. The audit revealed a low level of awareness of health and safety issues at all levels of management and a lack of occupational medicine and industrial hygiene systems. Noise-induced hearing loss occurred among 92% of the study subjects. Among the 158 dam construction workers, 5.4% had pneumoconiosis. With poorly developed laws and regulatory bodies, unsophisticated trade unions, and little client supervision, health and safety had a low priority in this construction project. Recommendations are made that are pertinent to health and safety management where international companies are operating in developing countries.
