ABSTRACT
Introduction: Studies of the vibrations generated in industrial metal platforms were carried out to prevent danger of risk to the health of exposed workers and to identify the areas and workstations that require special control measures from the design stage. Objectives: To analyze the danger posed by the propagation of general vibrations in industrial metal platforms and to assess the risk distribution according to the motor power installed in them. Methods: Three vibration dosimeters from the Danish firm Brüel & Kjaer (Human Vibration Analyzer Type 4447) were used, with the corresponding triaxial accelerometer of the Sead Pad type. The studies were risk assessments in view of a comparative analysis of these vibrations in the working areas of three different industrial metal platforms that included trial-error procedures for the necessary adjustments in the field measurements. Results: The modified standard ISO 2631-1, -2 applied to the assessment of general vibrations adequately replaced the currently valid Cuban standard NC 19-01-05, and allowed preventing the risk of exposure to nonconstant and impact vibrations, as well as the potential harmful effects generated by shock waves not detected with the methodology estab-lished in the Cuban standard. Conclusion: The propagation of shock waves in these plat-forms depended on the power of the installed machinery; therefore, in order to control the risk, an adequate design for these structures is required.REFERENCES
