The manual transport of load and the commercial aviation in Brazil

The Brazilian commercial aviation industry has grown strongly in the last decades, increasing passenger capacity and operational safety. While several studies focus on flight safety and passenger comfort, few are dedicated to the manual transport of loads. Although apparently this sector has low relevance, every year nearly 9% of their workers are injured. It is estimated that these injuries cost more than 10 million dollars a year to the companies involved. This study assesses quantitatively the risk of injury on employees. NIOSH method was used to evaluated the possibility of injury in different tasks. Factors such as the pace of activity, horizontal and vertical displacement, and asymmetries were evaluated during loading and unloading of luggage. This study showed that the frequency of repetitions of loading was excessive in all cases analyzed. However, the use of conveyors reduced the risk of employee injury, reducing this possibility to acceptable levels. The study shows that simple measures can help reduce the number of injuries and hence the cost that this entails.
