The present work will deal with the application of the Regulatory norm 12
focused on the case study of an interlocking safety barrier system for an unwinder,
reel carriage and reel tipper system of a one-piece aluminum cap forming press.
factory located at the Manaus Industrial Pole using programmable controllers and
safety devices in accordance with the rules set forth in Regulatory norm 12. The
scope of this paper is formed by a brief history of the emergence of occupational
safety standards, machine safety system types, safety guards, sensors, valves,
safety blocks, Programmable Logical Controller, interlocking devices, emergency
stop, lifting. and understanding of the process and each equipment that makes up the
system, process risk analysis and measures taken to carry out the project
implementation. Such approaches aim to show the regulatory norm 12 and its
applications in the safety system that will be presented as object of study of the
safety barrier implantation system obeying the items established in the regulatory
norm 12 whose purpose is to avoid work accidents, improving the safety of the
workers. production technicians and mechanics who are part of the equipment
preventive, corrective maintenance and operation process. At the end will be
presented a table with the before and after the result of the implementation of this
work to verify the improvements presented.
