Introduction: In 2018, in the Physical Testing Laboratory of the company where the study is carried out, 40% of the Inspectors and Sample Manipulators report discomfort in some part of their body. Of all those reports, 61% report lower back pain. The National Institute of Occupational Safety and Health of the United States (NIOSH) indicates that there is strong evidence that associates the lift, pushing, pulling and vibration of the entire body with lower back pain. Objective: To determine the relationship between the risks associated with manual modifications of loads and musculoskeletal symptoms in the inspectors and sample handlers of the Laboratory of Physical Tests of mineral concentrates. Participants: The application of the Nordic questionnaire was carried out to 14 Inspectors and sample handlers. Results: If there are musculoskeletal symptoms, then there are the causes they cause, these causes are the risks associated with manual handling of loads. Seniority in the position ranges from 8 months to 11 years, 71.43% have more than two years in the position and engineering controls such as the acquisition of 3 metal cars, an elevator, an electric stacker and the installation of arms tires; They have been used frequently since November 2017, that is, less than 2 years. According to the application of the Nordic questionnaire, 78.57% of the Inspectors and Sample Handlers mention that they have had back discomfort, 71.43% respond that they have had it in the last 12 months and 57.14% in the last 7 days; However, only 28.57% have received treatment for these discomforts, the type of treatment received are physical therapies, evaluations by traumatologist and analgesics for back pain. Of all the tasks performed by the Inspectors and Sample Manipulators, 21 tasks are identified where they carry out lifting / lowering or transporting bags / boxes with mineral concentrate. The 21 tasks are evaluated, 5 using the MAC methodology, 11 with the V-MAC methodology and 5 with the RAPP methodology; these methodologies are used by the United Kingdom Health and Safety Executive. Of the 21 tasks where there is manual handling of loads, in 19.05% there is a HIGH RISK, in 52.38% there is a MODERATE RISK and in 28.57% the RISK IS LOW. According to Pinder's action categories, 71.43% ACTION IS REQUIRED and 28.57% NO ACTION REQUIRED. Conclusions: From the risk assessment, it is concluded that in 71.43% of the tasks, the risk is not controlled, that is to say that there are risk factors that can add to generate musculoskeletal discomfort and according to the Nordic questionnaire there are musculoskeletal symptoms in the lumbar back. Recommendations: Finally, the general and specific recommendations to be implemented are detailed, according to the uncontrolled risk factors found in our study, in order to avoid damages and losses, to increase the productivity and workers life quality and their families.
