Background: Colombian brake mechanics perform manipulation activities of Asbestos Containing Brake Products (ACBP), which release asbestos fibers exposing workers. Sampling campaigns are the most accurate method to determine exposure, but are expensive and time consuming. This study applies a different methodological approach to estimate current asbestos exposures among brake mechanics in large metropolitan areas, which can also be used for the reconstruction of their historical exposures. Aims: Identify both Bake Repair Shops (BRS) and brake mechanics that manipulate ACBP in selected zones of Bogotá (Colombia), and estimate current and historical asbestos personal exposures. Methods: Two areas with a large number of BRS in Bogotá (Colombia) were selected, and BRS located in these areas were visited. Structured questionnaires based on the OSHA Medical Questionnaire were culturally adapted and used for data collection. Annual personal exposures to asbestos were estimated based on: 1- the activities reported by workers and 2- the range of PCM-Equivalent personal exposures to asbestos previously determined by our research team in studies conducted in this occupational group. Estimations were compared against an annual standard of 25f/cm3. Results: A total of 90 workers' occupational histories from 37 BRS were collected. Theoretical estimates of annual personal exposures to asbestos ranged from 1,2 to 297,4 f/cm3 per year. The percentage of workers exceeding annual exposures of 25 f/cm3 ranged from 59% (i.e., using the lower concentration of the exposure range) to 88% (i.e., using the higher concentration of the exposure range). Conclusions: Manipulation processes of ACBP are still common in most of the BRS visited, although the number of ACBP manipulated has declined over time. Estimates suggest that an important number of brake mechanics may have been exposed to asbestos concentrations above the annual standard.
