Analysis and remediation of risks in industrial machines according to the standards ISO 12100 - ISO13849-1
This working Paper presents the general process to carry out the risk analysis of industrial machines, indicating the main characteristics and definitions of the preventive measures of the security functions implemented through the ISO 13849-1:2015 standard, made up of the logic subsystems, input and output. The methodology proposed in ISO 12100:2010, allows to establish the limits of a machine, the dangers related to the operation. Establishing five levels of PL benefit, from the lowest PLa to the highest Ple. Through probabilities of dangerous failure, with which the reduction of the risk of the machine and the operator.
