Productivity increase in the production line in the recharge of fire extinguishers based on industry 4.0

Abstract

Fire extinguisher recharging and fire control using dry chemical powder (DPC) are crucial practices globally, especially in view of the alarming increase in fires and the imperative need for operational and effective fire extinguishers. These devices, essential for safety, have an expiry date that makes their periodic maintenance mandatory. In Peru, the companies responsible for recharging fire extinguishers operate under the Peruvian Technical Standard NTP 350.043-1. However, many of these companies carry out the recharging process manually, exposing workers to the risks of handling PQS, a substance harmful to health. In addition, manual procedures are repetitive and susceptible to human error, highlighting the need and potential for adopting advanced technologies to improve efficiency and safety in these processes. The research work focuses on the improvement of the PQS fire extinguisher recharging production line based on Industry 4.0 of the company "Fumisem S.A. C", for which it was necessary to know the processes that perform through a visit, in which a study of times by means of chronometer was made, then to establish the diagram of route, the Diagram of operations of the Process (DOP), The Analytical Diagram of the Process (DAP), which were key to establish the operations, inspections, inputs for each process, likewise the productivity and the unproductivity was seen, on the basis of it the industry 4. 0 where a plant is simulated to scale of the operation of the recharge of fire extinguishers, which was made based on all the requirements and processes described in this work, likewise this work raises the elimination of manpower which will be replaced by industrial automation, on the other hand this type of approach is efficient because the machines do not perform unnecessary movements which improves productivity and times in the recharge of fire extinguishers.
