Module ID 04404 - Fume and Exhaust System Design
Exhaust systems are primarily used to move air
from inside a structure to the environment outside.
There are many reasons to exhaust air from
a building, with the removal of airborne fumes
and contaminants being a common goal. Several
categories of filtration and exhaust systems are
introduced here. Each type is effective or preferred
in one or more applications. Sheet metal
craftworkers should be familiar with the equipment
and duct systems used in exhaust and ventilation
applications. Depending on the application,
the duct fabrication and installation requirements
can be significantly different from those related
to conditioned-air distribution. (25 hours)
Module ID 04403 - Welding and Brazing
Welding and brazing are important skills for sheet
metal workers to learn. They are tasks that require
special training, practice, and a keen awareness
of the hazards involved. As a sheet metal trainee,
it is important to learn how to safely and properly
operate the equipment used for welding and
brazing as well as how to produce quality results.
Although it is unlikely that these tasks will be
performed continuously without a great deal of
additional training and practice, they are skills
that are essential when the need arises. (20 hours)
Module ID 29102 - Oxyfuel Cutting
Oxyfuel cutting is a method for cutting metal that
uses an intense flame produced by burning a mixture
of a fuel gas and pure oxygen. It is a versatile
metal cutting method that has many uses on job
sites. Because of the flammable gases and open
flame involved, there is a danger of fire and explosion
when oxyfuel equipment is used. However,
these risks can be minimized when the operator
is well-trained and knowledgeable about the
function and operation of each part of an oxyfuel
cutting outfit. (17.5 hours)
Module ID 04307 - Architectural Sheet Metal
This module introduces a variety of basic roofing
components, including flashing, gutters, and
downspouts, as well as the standing seam system
used for many metal roofs. All these components
work together to move water off a roof and
keep it from penetrating into vulnerable areas.
The included projects provide trainees an opportunity
to practice their lay out, fabrication, and
installation skills. Components such as roof decking
panels, wall cap flashing, roof edge flashing,
scuppers, and gutters are introduced, along with
basic guidance for their fabrication and installation.

Module ID 04401 - Shop Production and Organization
To remain competitive in the construction industry,
a sheet metal shop must continually strive
to optimize the processes used to fabricate and
prepare materials for field installation. Optimization
includes attention to the physical layout of
the shop, planning sessions related to the unique
needs of current jobs, and the way that paperwork
and digital documentation is accomplished. This
module examines common production practices
used in sheet metal shops and the importance of
careful planning to best support the field installation
activities. (25 hours)
Module ID 04407 - Sheet Metal Business and Technology
The sheet metal and HVAC industries continue to
become increasingly competitive. Today’s client
expects projects to be finished faster and delivered
at a lower cost. This highly competitive market
is forcing the industry to find new ways to live
up to those expectations. One way that many companies
are doing so is by incorporating advancements
in software and technology into their
workflows. There are now various software tools
and platforms that HVAC companies are using to
enhance processes including design, estimation,
fabrication, installation and project documentation.
Since technology has become commonplace
in the industry, understanding its importance and
what it can do is important for all craftworkers.

Module ID 46101 - Fundamentals of Crew Leadership
When a crew is assembled to complete a job, one
person is appointed the leader. This person is usually
an experienced craft professional who has
demonstrated leadership qualities. While having
natural leadership qualities helps in becoming an
effective leader, it is more true that “leaders are
made, not born.” Whether you are a crew leader
or want to become one, this module will help
you learn more about the requirements and skills
needed to succeed. (22.5 hours)
