The Machinery Safety Applications program applies to personnel involved in the implementation of safety-related systems in Machinery Applications.

This exam is for the Process Safety Engineer, Process Engineer, Control Engineer, Control Engineer, Maintenance / Instrumentation Technician, Project Engineer, Reliability Engineer, Machinery Engineer, Electrical Engineer, Engineering/Operations Management Operator.

The CFSE Advisory Board, in conjunction with industry experts, determines curricula based on the competencies required by international standards and industry best practice. As industries evolve through the application of improved or different technology, the Advisory Board reserves the right to revise curricula to reflect these changes.

The CFSE Advisory Board highly recommends that you study at least 40-50 self-study hours for preparation of the CFSE/CFSP exam.

Recommended Standards:

  • IEC 61508
  • IEC 62061
  • EN ISO 12100
  • EN 13849

Recommended Course:

Sample Exam:

Questions related to configuration of Management, Functional Safety Management, and Safety Architecture may be asked. These are all areas that must be understood by both hardware and software engineers to avoid safety design errors. Engineers should have a good understanding of diagnostic techniques that often require a combination of hardware and software.
The curriculum for this program consists of general knowledge plus the knowledge in the applicable field of expertise:
