"The Future of Industrial Training: the New Digital Classroom"



About the Webinar:
At TPC Training Systems, we’ve been on the hunt for ways that our industrial skills training solutions can evolve to meet the needs of all of our customers, and we’ve learned some things in the process. In this webinar, we’ll share what we’ve learned and give you a preview of the future of industrial training.

You’ll learn about:
  • The best uses of webcast and simulcast training formats
  • The advantages of blended online and live training
  • Virtual reality (VR) training environments, including an exclusive sneak peek inside a VR simulation

    Purging, Piping, and Safety

    Purging, Piping, and Safety

    Explains the effects of noncondensables on an ammonia system and the importance of their removal. Covers a wide range of piping considerations-sizing, flow rate, pressure drop, and others. Concludes with a thorough coverage of safety codes and programs, including ANSI/ASHRAE, IIAR, OSHA, and EPA information.

    TPC Training Systems is authorized by IACET to offer 0.5 CEUs for this program.

    Lesson 1 - Purging Air and Noncondensables

    Topics:

    Materials to be purged; Effects of noncondensables; Power penalty; Purge point locations; Automatic purging; Economics of purging

    Learning Objectives:
    – List common noncondensable vapors and discuss their effects in a refrigeration system.
    – Discuss the power penalty resulting from noncondensable gases in terms of compression and loss of refrigeration capacity.
    – Explain how to determine the presence of noncondensables.
    – Explain how to minimize the entrance of noncondensables and describe common entry points.
    – Compare the features and operation of manual and automatic purging equipment and name the best connection points for the purge unit.
    – Discuss the economic benefits of the purge unit in terms of typical payback times.


    Lesson 2 - Ammonia System Piping

    Topics:

    Pressure drop in pipes; Laminar and turbulent flow; Line sizing, flow rate, suction line pressure drop, discharge line pressure charts; Special piping situations

    Learning Objectives:
    – Discuss the relationship between pressure drop requirements and pipe sizing.
    – Discuss the factors that affect the pressure drop in a pipe.
    – Explain the significance of the Reynolds number and the distinction between laminar and turbulent flow.
    – Discuss the use of various kinds of line sizing charts including flow rate tables, equivalence tables for fittings and valves, and pressure drop charts.
    – Explain how to select the proper suction line, discharge line, and liquid line sizing for an ammonia system.
    – Discuss special piping situations that require alternative sizing or installation.


    Lesson 3 - Ammonia System Safety Codes and Guidelines

    Topics:

    Codes for ammonia refrigeration systems; ANSI/ASHRAE 15-1994; ASMEB 31.5; IIAR2; IIAR bulletin 111; IIAR bulletin 112

    Learning Objectives:
    – Describe the basic differences between ASHRAE and ASME codes and IIAR standards and guidelines.
    – Discuss several main points in the ASHRAE 15-1994 safety code for mechanical refrigeration.
    – Describe code requirements based on the occupancy classifications, leak probability classifications, and refrigerant characteristic classifications.
    – Describe several requirements in the ASME B 31.5 refrigeration piping code concerning the materials and fabrication of refrigeration piping systems.
    – Name several safety requirements specified by IIAR 2 for ammonia refrigeration equipment.
    – Describe the kinds of information provided by IIAR bulletins.


    Lesson 4 - OSHA Process Safety Management

    Topics:

    OSHA regulations; PSM requirements; Estimation of ammonia inventory; PSM plan development; Process safety information, hazard analysis; Standard operating procedures; Contractor procedures

    Learning Objectives:
    – Discuss the purposes of Process Safety Management and describe the thirteen elements that make up PSM.
    – Describe the process for estimating a plant's ammonia inventory and establishing a plant ammonia library and explain why each is needed.
    – Discuss the personnel and steps involved in developing a PSM plan for a specific refrigeration plant.
    – Describe the process hazard analysis (PHA) and explain how it can reduce the likelihood of ammonia accidents and spills.
    – Describe the requirements for preparing standard operating procedures (SOPs) for all normal plant service, repair, and maintenance.
    – Discuss contractor responsibilities for PSM.
    – Discuss the importance of management-of-change procedures in keeping paperwork up to date.


    Lesson 5 - EPA Regulations and Ammonia Safety

    Topics:

    40 CFR 68; Worst case/alternate ammonia release scenario; Elements in common with OSHA PSM; Penalties for nonconformance

    Learning Objectives:
    – Describe the purposes of the EPA Risk Management Plan and compare it to the OSHA Process Safety Management program.
    – Explain the reasoning behind the dual hazard assessment requirements of a worst-case ammonia release and the more practical alternative ammonia
       release.
    – Discuss the toxic end point criteria for an ammonia release and distinguish between rural and urban end points and differences in requirements.
    – Discuss the importance and difficulties of presenting the required release data and plan to the community.
    – Discuss the hazards of working with ammonia and the importance of using personal protective equipment to avoid or minimize the effects of an
       ammonia release.
    – Describe correct first aid procedures pertaining to contact with ammonia vapor and liquid.
