Setting Up a Qualified Electrical Worker Program At Your Facility

OSHA and NFPA talk about setting up a qualified electrical worker program but what exactly does that mean? How do we get there? And what training is needed? TPC Trainco Electrical Instructor Mike Leitzel will guide you through setting up your own QEW program at your facility and answer your questions to keep your employees safe.

Heating System Equipment

Heating System Equipment

Covers the hardware associated with heating systems, including gas and oil furnaces, electric systems, solid-fuel and hydronic systems, and finally some alternative systems–solar heating, heat pumps, and fuel cells. Includes a discussion of furnace performance criteria, return air systems, and the importance of filters.

TPC Training Systems is authorized by IACET to offer 0.6 CEUs for this program.

– Describe the main parts of the furnace system, both those that produce the heat and those that distribute the heated air, and describe the four basic
   furnace configurations.
– Discuss the differences between natural gas and liquefied petroleum gas (LPG), the hazards associated with each fuel, and the heating rates of each
– Discuss the purposes of the primary and secondary air supplies to the combustion chamber and compare the characteristics of category I, III, and IV
   gas furnaces.
– Describe how the gas is introduced, mixed with the air, and burned in the heat-producing components of the furnace.
– Describe several burner ignition methods and safety shutdown measures in case of flame failure.
– Discuss the basic sequence of furnace operation and the controls required.
– Describe common service procedures for gas heating systems and discuss safety.

Lesson 2 - Oil Heating Equipment
