Course Description
The Certified Respiratory Train the Trainer (CRTT) course is a comprehensive professional certification program designed for safety professionals, Environmental Health and Safety (EHS) managers, occupational health specialists, industrial hygienists, supervisors, compliance officers, and workplace trainers responsible for developing, implementing, and managing OSHA-compliant respiratory protection programs. This course provides participants with the knowledge and instructional skills required to train employees, perform respirator fit testing, and administer effective respiratory protection programs in accordance with OSHA 29 CFR 1910.134.Respiratory hazards are present in numerous industries including manufacturing, construction, healthcare, mining, oil and gas, chemical processing, pharmaceuticals, utilities, and emergency response. Employees may be exposed to airborne contaminants such as dust, fumes, mists, vapors, gases, biological hazards, and oxygen-deficient atmospheres. This certification prepares participants to recognize respiratory hazards, select appropriate respirators, conduct employee training, and maintain OSHA regulatory compliance.
Participants will gain an in-depth understanding of OSHA Respiratory Protection Standards, respirator selection, air-purifying and atmosphere-supplying respirators, respiratory hazard assessments, written respiratory protection programs, medical evaluations, qualitative and quantitative fit testing, respirator maintenance, cleaning, inspection, storage, recordkeeping, and program evaluation. The curriculum also covers adult learning principles, instructor development, effective training delivery, competency assessments, and best practices for managing respiratory protection programs.
Through practical demonstrations and hands-on training, students will learn how to conduct fit testing, perform seal checks, inspect respirators, train employees on proper respirator use, evaluate respiratory protection program effectiveness, and ensure compliance with OSHA regulations. The course emphasizes hazard recognition, worker protection, instructor competency, regulatory compliance, and continuous improvement in respiratory safety.
Upon successful completion of the Certified Respiratory Train the Trainer (CRTT) course, participants will have the expertise to lead respiratory protection training programs, administer fit testing, manage OSHA-compliant respiratory protection programs, and improve workplace safety across a wide range of industries. This certification is ideal for professionals responsible for respiratory protection, occupational health, industrial hygiene, OSHA compliance, and employee safety training.
