Course Description
The IASHEP Certified Machine Guarding Specialist - Trainer (CMGS - Trainer) course is a comprehensive 4-day professional training program designed to equip participants with the knowledge and practical skills needed to recognize, evaluate, and control machine hazards in industrial workplaces. This course prepares safety professionals, compliance officers, technical instructors, maintenance personnel, and training managers to deliver effective machine guarding training and support compliance with OSHA regulations, ANSI standards, and ISO requirements. Participants will learn how to identify machine hazards, conduct risk assessments using ANSI B11.TR3, measure safe opening distances, design and install machine guards, and implement effective safeguarding solutions for a wide range of machinery. The course also covers specific guarding techniques for milling, drilling, boring, metalworking, hydraulic punch presses, bandsaws, spot welders, and more. Practical instruction focuses on guard design, fabrication, installation, and the application of Lockout/Tagout, electrical safety requirements (NFPA 79), and ANSI/ISO standards. Upon successful completion, participants will be certified to train others in machine guarding principles and practices. This is not an OSHA or OSHA Training Institute Education Center (OTIEC) Level Training program.What You'll Learn
