B5-4　Personal Protective Equipment Design and Ergonomic Work Analysis: Protecting Farm Pineapple Growers

Abstract

Pineapple growing is one of the most aggressive agricultural activities and worker protection is a considerable technical challenge. Previous studies point to the lack of efficacy of personal protective equipment (PPE) usually used by workers to protect themselves against accidents with poisonous animals and punctures by pointed leaves, particularly on harvesting activities. In view of these results, this study proposes a two-phase approach. First, a set of PPEs commonly used by rural workers was experimentally evaluated for its effectiveness in protecting workers against real venomous snake attacks. Four sets of PPEs were tested, including shoes and protective gloves, leggings and over sleeves, each set with three different models. The PPE that passed the real attack tests were then evaluated by a group of workers in real use situations, according to qualitative criteria, including comfort and usability. The results of the experimental evaluation showed that only 5 models were effective in protecting the workers against snake attacks, including one shoe model, two models of leggings and two models of gloves. The usability analysis of these PPE revealed that some of them were considered uncomfortable, not effective and obstructive. The next phase of this study relies on the results of the first phase and aims the conception, design and fabrication of a PPE set for the activity of growing pineapples. To generate the design parameters, it will be used an approach based on ergonomic work analysis and conventional design methods, with an emphasis on the QFD method. It is expected that the new set of PPEs will effectively protect the workers and facilitate, or at least not interfere adversely with task execution.
