About Me
I’m Humberto Vargas, founder of Benchmark SCG and a
Certified Machinery Safety Expert (CMSE® – TÜV NORD). My background includes hands‑on
experience with industrial machinery, functional safety, and compliance engineering across
multiple manufacturing sectors.
I started Benchmark SCG to provide manufacturers
with clear, practical, and standards‑based safety guidance — without the complexity or
overhead of large consulting firms. When you work with me, you work directly with the
expert.
My Approach
My work is grounded in international standards and real‑world manufacturing needs. Every
project follows a structured methodology:
• ISO 12100 hazard identification and risk assessment
• ISO 13849 PLr determination and PL verification using SISTEMA
• Conceptual safety design and device selection
• Validation of safety functions (ISO 13849‑2)
• Clear, audit‑ready documentation and recommendations
The goal is always the same: reduce risk, improve compliance, and support safe, reliable
production.
Tools & Standards
