[Application criteria of the OCRA method in the evaluation of the structural assembly of aircraft: preliminary data]
Abstract
In the aircraft productive sector, the risk assessment of repetitive occupational activities through the OCRA method presents some major obstacles: high number of different tasks (more than 20) carried out during the work shift; definite identification of the number of technical actions per cycle.
Risk assessment through the traditional OCRA method provides in this sector a index which varies according to the sampling of the occupational tasks, rather than reflecting the effective risk level. The study raises an OCRA-based method which is applicable in the aircraft production sector and defines the overall ergonomic load for homogeneous groups of exposed workers, based on production data specified for each aircraft model.
