Course Description
Certified Machine Guarding Specialist (CMGS)The Certified Machine Guarding Specialist (CMGS) course is designed to provide safety professionals, maintenance personnel, supervisors, and equipment operators with the knowledge and practical skills needed to identify, evaluate, and control machinery hazards in the workplace. Proper machine guarding is a critical component of workplace safety and plays a vital role in preventing serious injuries while ensuring compliance with OSHA regulations and industry best practices.
Effective safeguarding begins with selecting guards and protective devices that are compatible with a machine's operation and designed to protect operators without interfering with productivity. Factors such as machine type, operation, size and shape of materials, feeding methods, production requirements, and workplace layout all influence the selection of appropriate safeguarding methods. Poorly designed guards can encourage employees to bypass safety devices, increasing the risk of workplace accidents.
Throughout this course, participants will gain a comprehensive understanding of machine guarding principles, hazard recognition, and risk assessment techniques used in industrial and manufacturing environments. The course also covers the ANSI B11.19 Performance Criteria for Safeguarding, including the design, installation, operation, inspection, testing, and maintenance of safeguarding systems used to protect employees from machine-related hazards.
Students will explore OSHA machine guarding requirements, safeguarding methods, hazard control strategies, and the importance of Lockout/Tagout (LOTO) procedures when servicing or maintaining machinery. Real-world examples and practical applications help participants understand how to identify unsafe conditions, implement corrective actions, and improve workplace safety programs.
Upon successful completion of the Certified Machine Guarding Specialist (CMGS) course, participants will have the knowledge and confidence to evaluate machine guarding systems, recommend appropriate safeguarding solutions, support OSHA compliance initiatives, and contribute to creating a safer work environment. This certification is ideal for professionals seeking to strengthen their expertise in machine safety, reduce workplace risks, and advance their careers in occupational health and safety.
