Gas Pressure Systems Technician

Compressed, liquefied, and dissolved gases present a combination of stored-energy, toxic, flammable, and oxidizing hazards that demand rigorous technical control. This course prepares technicians to work safely with gas pressure systems, covering legislation and standards, system management, cylinder bundles and valves, low-pressure storage vessels, and safe filling operations. Participants develop the inspection and maintenance competence needed to identify defects, verify safety devices, and keep systems within their safe operating limits. The course reflects United States regulatory requirements while drawing on the ISO standards widely used in gas equipment design and testing.

Who Should Attend

• Gas filling plant operators and technicians
• Maintenance technicians responsible for compressed air and industrial gas systems
• Welding and fabrication supervisors managing oxygen and fuel-gas systems
• HSE officers overseeing gas storage and distribution areas

Learning Outcomes

• Identify the physical and chemical hazards of compressed, liquefied, and cryogenic gases
• Apply OSHA, NFPA 55, and NFPA 58 requirements to storage, handling, and use
• Describe the components and safe operating limits of a pressure system
• Carry out pre-fill inspection and safe filling of cylinders and cylinder bundles
• Inspect and maintain cylinder valves, regulators, and pressure-relief devices
• Specify compressed-air purity classes using ISO 8573-1
• Prepare inspection and maintenance records that demonstrate compliance

Assessment & Certification

Candidate competence is evaluated through a written examination and a practical assessment covering system inspection, valve and regulator checks, and a simulated filling operation. Successful candidates receive an IIME Certificate of Training bearing a unique verification code that can be confirmed online. The program comprises 40 contact hours (5 days).
