This study presents the adaptation of a test press to comply with Regulatory Standard
12 (NR-12) of the Ministry of Labor. During the risk analysis, it was identified that the
operator was exposed to the risk of hand crushing when positioning plates in the
machine's cradle. The objective of the research was to implement technical
modifications to ensure the machine's compliance with NR-12 and improve worker
safety. The adaptation was guided by the NBR ISO 12100 and NBR 14153 standards,
which served as the basis for the risk assessment, while the 5W2H tool was used to
detail the necessary modifications. The process involved the preparation of a
Preliminary Risk Assessment (PRA), machine adaptation with identified safety
components, compliance testing, and the preparation of a technical report certifying
safe operation. After implementing the adjustments, results showed a significant
reduction in accident risks and increased productivity. Furthermore, there was an
improvement in the quality of the plate tests, as the safety peripherals prevented
operator intervention during the validation process. In conclusion, the machine's
adaptation provided benefits for both worker safety and the efficiency and quality of
the production process.
