The fire I have chosen to discuss is the mega warehouse Walmart fire in Plainfield,
Indiana, on March 15, 2022. This fire is interesting because the system itself did not fail,
however it still was unable to stop the fire. It highlights one key problem system designers must
account for but can never truly eliminate.
On this day fire fighters were called to a large warehouse fire containing flammable and
combustible consumer goods. The fire originated on the second level of a four-level racking
system that was loaded with combustible consumer goods. Automatic sprinklers protected each
level of this storage area. The sprinklers on the second level had performed as expected and all
that remained was a mass of burned debris that was saturated with water.” (National Fallen
Firefighters Foundation Firehero) The reports from the fire fighters indicate that after the fire
was “extinguished” the firefighters began to work on your typical issues that would follow a fire.
They claimed there was nothing out of the ordinary. Because of this belief, the fire pump was
shut down, cutting off the supply of water to the system. The firefighters say 10 minutes later,
while on the roof the fire showed signs of life again through the production of smoke. They
claimed that within 90 seconds the fire was ablaze again and devouring the warehouse.
What was the reason this system failed to extinguish the fire? The answer is very simple,
user error and misjudgment. The warehouse was full of highly flammable and combustible
objects stacked on rack storage. To the trained professional, this screams higher probability of
fire spread in case of a fire. When the firefighters entered to extinguish the remnants of the fire
and search for employees, they made two mistakes. The first was too not properly assessing the
fuel load capabilities of the building. The second was turning off the pump too prematurely.
There is no exact time that the pump must be shut off, however it is important to recognize the
hazardous fuel loads and potentially leave the system active and reset until they are ready to
leave. The important lesson is that at the end of the day, a designer, technician, fire marshal, or
even installation individuals can not plan and create a system to protect from human error. This is
why there are stringent requirements on licenses and titles to ensure failures do not happen do
too human error.
