Retail facilities in the part where cured meat products and cheeses are sold have a need to organize queues where only the environment where the QMS is installed is so as to cause a high risk of mechanical failures caused by contact with water and oil or falls. For that reason, the best prevention of frequent mechanical failures is to call from weighing scales installed in the department where dried meat products and cheeses are sold, which also ensure the mobility of workers by enabling roll calls from each of the installed scales.
