Evaluación en la manipulación de carga en la empresa CCC LOGISTICOL SAS mediante la ecuación NIOSH

Abstract

In this work, the level of ergonomic risk with musculoskeletal disorders present in manual lifting of loads in the C.C.C company is analyzed. LOGISTICOL S.A.S. through the evaluation of the risk associated with the task of loading and unloading merchandise in the Cota-Funza warehouse with a total of 45 workers at risk of very high exposure to biomechanical risks. For this, 3 objectives were developed; First, the difficulty in manually lifting loads was estimated through assessment of the physical load following the NTP 177 guide and it was concluded that the thermal load has a total value of 373 Kcal/hour, which shows that the unloading of merchandise in the undertaking may be considered a heavy physically demanding job; Second, the assessment of the risk of thermal stress was carried out: WBGT index in the loading and unloading area, which resulted in 16.79°C. Based on this value and according to NTP 322, it is concluded that there is no thermal stress, on the contrary, there is thermal discomfort and finally the level of ergonomic risk was determined according to the NIOSH equation, for which the analysis was carried out. with the highest frequency and weight products; The factors of height, asymmetry, frequency and grip were determined. Based on the above, it was determined that among the factors that most affect the health of workers is the 45° turn with the trunk that they perform repetitively to carry a significant weight, the low recovery times between tasks, adding to a poor grip factor due to the poor design of the boxes since it does not have perforated handles or handles for greater grip and not all products come with optimal designs and in some cases they are bulky. In general, it is advisable to study the job and make modifications. The work ends with some recommendations that the company can put into practice, among which the elimination of horizontal distances, the reduction of load sizes, improvements in the arrangement of the load at a height that avoids discharges above the of the shoulders and lifts close to the ground, using load management techniques that allow the use of the leg muscles more than the back muscles. This requires joint work between the workers and the management of the company since a training process, modification of tasks, work times and frequencies, as well as job rotation, periodic medical evaluation and improvements to the training program will be necessary. Epidemiological surveillance against musculoskeletal disorders, to follow up on all cases that occur. Given that the company has several offices in the country, it is proposed that the study be carried out on all platforms to provide a broader scope with activities in favor of the worker.
