Resumen
Occupational exposure to cement and crystalline silica has been studied for years in countries like US and Canada, when cement dust is inhaled during different work related activities, it can cause respiratory problems to the exposed workers. The study “Occupational exposure to cement and crystalline Silica in cementing and fracturing services lines for Oil & Gas Industry in Colombia: a retrospective study (2009 – 2013)”. allows identify role activities with potential risk of exposure for the presence of airborne particles, analyze a database including 18929 records for hygiene measurements in Oil and Gas industry, then calculate the portion of particulate matter in the respirable crystalline silica fraction and process the data statistically, confront these statistical estimators with permissible exposure values defined by the national government, results included the characterization of occupational exposure profiles for functional activities in cementing process, identifying workers at risk according to their exposure conditions and which of these profiles exceeded the maximum permissible limits for a work shift of 12 hours, this information will allow health professionals to establish surveillance programs to control these specific groups. For hydraulic fracturing process the data found was not statistically significant.
