MIL-HDBK-1027/1B
(2) The advanced course is a 2-day course: 16
hours of combined classroom and trainer instruction. Maximum
class size is 12 students.
(3) The team course is a one-day course: 4 hours
of trainer instruction. Maximum class size is 14 students.
3.2
General. Design the training structure to house the
various 19F and 21C12 series devices and provide realistic
training situations. It should be ruggedly constructed to
withstand the temperature cycling from the intense heat of the
flame to a stream of cold water from a hose. It should
withstand the impact of a high velocity hose stream.
3.2.1
Heat Protection. Building structural components
should have sufficient room for thermal expansion. The maximum
flame temperature of the device is 899 degrees C when using
propane fuel. Assume the products of combustion reach 349
degrees C and an individual compartment may reach 204 degrees C.
Any item located in a compartment should be able to withstand
the radiant heat or be shielded from it. It takes about 5
minutes for a small fireplace and about 20 minutes for a large
fireplace, such as a bilge fire, to return to the starting
temperature assuming 2 minutes of cooling water spray.
3.2.2
Personnel Spacing. There will be approximately 1550
mm of spacing between trainees on a hose team.
3.2.3
Weather and Freeze Protection. Weather protection of
the training structure should meet the following criteria:
a) Structures should be sufficiently enclosed and
heated to allow training in subfreezing weather (where this is a
requirement) without adverse effects, such as, ice buildup on
grating or doors. Other than for training and water freeze
protection, there is no low temperature limit on the structure
or associated equipment during off hours.
b) Crawl space should be heated to 4.4 degrees C
during unoccupied hours to maintain the structure above
freezing. Unit heaters should be used to provide heat.
