Extension of the Lean 5S Methodology to 6S with An Additional Layer to Ensure Occupational Safety and Health Levels

Abstract

En este trabajo se propone una ampliación de la metodología Lean 5S, en la cual se incluye como 6S el concepto Safety-Security. La implantación se realiza con un proceso estandarizado y testeado en un área piloto, incluida en el Laboratorio Industrial de Sistemas Integrados de Fabricación de Escuela Técnica Superior de Ingeniería - ICAI. El objetivo principal ha sido aumentar el alcance de la metodología 5S para dar respuesta a las necesidades de prevención de riesgos laborales y seguridad de máquinas requeridas en la optimización de los procesos de producción.

This paper proposes an expansion of the Lean 5S methodology, which includes the concept of Safety Security as 6S. Implementation was done by a standardized process tested in a pilot area that is part of the Integrated Industrial Manufacturing System Laboratory at the Higher Technical School of Engineering (ICAI). The additional 6S phase (Safety-Security) thoroughly reviews all areas of an industrial plant by analyzing the risks at each workstation, which let employees be fitted out with protection resources depending on each of their personal characteristics and to guarantee the safety of the workstation by strictly complying with occupational safety and health and machinery use standards, which must hold a CE certificate of compliance.
