Condensation woes
Warm, humid days and cool nights
are a recipe for condensation.
If left unchecked, condensation
inside a warehouse can lead to:
* Slippery concrete fl oors
* Hazardous working conditions
* Rust
* Mold and mildew
* Damaged products,
equipment and inventory
hile the spring and fall seasons
bring great weather, they also bring
a problem all too familiar to warehouse
facility managers: condensation. More
than simply an annoyance, condensation
has the potential to create dangerous
working conditions for warehouse
employees, and it can ruin expensive
products and inventory.
There are several ways in which airlow
can help to prevent or reduce condensation.
To understand how airlow
mitigates condensation, it's important to
learn how and why condensation forms.
How condensation occurs
Condensation forms when warm, moisture-laden
air contacts a colder surface.
For example, consider a cold can of soda
that " sweats " on a hot summer day. This
happens because air cools next to the
can, and cooler air holds less moisture.
Water is deposited onto the cold surface
when the air cools to the point where it
can no longer hold moisture. This is commonly
known as the dew point.
This same " sweating " scenario can
happen with a concrete loor, a giant coil
of sheet metal or cardboard boxes. But
unlike a soda can, wet loors and products
can be costly.
Spring is the most problematic time for
condensation because large, dense objects
are slow to react to air temperature
changes. A roll of sheet metal might hold
its winter temperature for days or weeks
after the weather warms. And it can take

a month or more of warm weather for the
core temperature of a concrete slab to rise
above the dew point.
During the fall months, it's common
for the dew point to surpass the surface
temperature of loors, products and
equipment. When warmer air moves in
during the day, it brings a rise in dew point
and humidity which causes a slick layer of
condensation to form over colder objects.
During the fall and winter months, it's
common for condensation to form on
products that have been moved from a
cold truck into a heated warehouse.
Condensation can be dangerous
Wet warehouse loors can lead to employee
slips and falls, and they can
prevent forklifts from slowing down.
According to EHS Today, slip and fall accidents
cost approximately $70 billion in
workers' compensation claims and associated
medical costs every year, with an
average of $20,000 in claims per accident.
Condensation also causes rust, mold and
mildew, which can cost businesses billions.
Rust alone costs the production
and manufacturing sectors roughly $17.6
billion each year, and can be damaging to
both products, facilities and equipment.
How proper airfl ow can help
While there are numerous factors that
cause condensation-weather patterns,
heat, humidity and dew point-there
are many ways to combat it, too, such
as through the use of dehumidiiers
