Consideraciones metrológicas en los requerimientos de exposición a vibraciones en la normativa de Seguridad y Salud en el Trabajo

Abstract

The regulations on health and safety at work are one of the pillars of occupational risk prevention. Many aspects are evaluated by different regulations to ensure the safety of personnel in different sectors. In order to establish the acceptable parameters at each case, the standards establish reference values that ensure the safety of personnel. In order to determine whether a certain parameter remains within the established limits, reliable measurements of the levels measured in the working area are necessary. Thus, measurement procedures are established for various aspects and sectors: mechanical resistance of safety nets in temporary work on construction sites, resistance of telescopic ladders, or the vibration meters used in various industries and applications, etc. Although in all cases the available standards propose measurement procedures and reference values, sometimes the reliability of the measurements is not evaluated in detail, and more exhaustive studies of the measurement processes, the repeatability of the values obtained and the uncertainty associated to the final measurements are necessary. By increasing the reliability of those measurements it would be possible to improve safety at work.
