Several sources of dust exist in
most poultry houses, including
bird feathers and dander, dried
urine and feces, insect parts and
feed grains. Dust particles can be
particularly threatening during
winter months, when poultry
houses are likely to be closed more
tightly and workers spend more
Harmful molds, bacteria, pro
teins, and endotoxins may attach
themselves to tiny, invisible dust
particles. Very small particles of
dust are often referred to as
As this term implies, respirable
dust is breathed in during normal
breathing. Harmful dust breathed
deeply into the lungs is also
referred to as “toxic dust.”

Toxic dust can cause an abrasive
irritation to the inside of the lungs,
a condition known as “pneumon
coniosis.” As more dust is inhaled,
irritating an already severe condi
tion, the lung’s efficiency is
reduced. This becomes a chronic
or long-term disability, which
adversely affects energy and exer
tion levels. Farmers of any age
with this condition may not have
the ability to accomplish farm
tasks that require an increased
level of strength and endurance.
More serious effects from brea
thing in toxic dust over several
years includes organic dust toxic
syndrome, or ODTS. This illness
has flu-like symptoms such as fev
er, headache, and muscular pains.
The symptoms usually appear four
to six hours after exposure to the
dust, and may lead to hospitaliza
tion for severe respiratory distress.
Studies have revealed that many
poultry farmers have excessive
dust inhalation symptoms, includ
ing burning eyes, runny nose,
scratchy throat, abnormal produc
tion of sputum and phlegm, and

All farmers and farm workers
should use personal protective
equipment when working in dusty
buildings. Use respirators
approved by the National Institute
of Occupational Safety and Health
(NIOSH). If a respirator is
approved by NIOSH, you will be
able to find a registration number
preceded by the prefix “TC” some
where on the respirator. An easy
way to quickly verify that a respir
ator is approved is to count its
straps. All approved respirators
have two straps. The single-strap
dust mask commonly found in
many stores is not approved by
NlOSH—nor is it effective at pro
tecting the wearer from respirable
It is always better to prevent
respiratory problems than to try
and minimize their effects after
some damage has been done. Even
if you have not experienced symp
toms of respirable dust inhalation,
you should always use personal
protective equipment when work
ing in poultry houses.
Use a properly fitted and main
tained respirator. Farmers who
have beards or wear glasses should
be particularly careful to fit respir-

One type of respirator that
appears to be increasingly popular
in poultry houses is the powered
air-purifying respirator (PAPR). A
PAPR is simply an air-purifying
respirator with a motorized blower
that forces air through a filtering
device. It makes breathing easier
for the wearer, so this type of
respirator may be recommended
by a doctor for someone with a
minor respiratory or cardiovascu
lar ailment. They tend to be cooler,
too, because they provide a con
stant stream of air over the wear
er’s face and head. Many PAPRs
have a hard helmet and rigid visor
under which the air is blown.
There are also half-mask and full

face models, as well as models
with non-rigid helmets.
A PAPR can protect you from
dusts, mists, gases, and vapors
provided you equip it with the right
filters. The blower is powered by a
battery pack strapped onto the
wearer’s waist or back. Recharge
able or disposable D-cell batteries
can be used, and most batteries last
6-8 hours. You also can use a 12V
or 24V DC adapter, which will run
the blower from a vehicle battery.
Respirator prices vary consider
ably depending on the type you
need. Disposable mechanical filter
respirators can be bought for under
$lO. Many non-disposable models
cost less than $5O. A PAPR may
range in price from $lOO to $5OO.
No matter which type of respira
tor is most appropriate for you, the
cost of the respirator is insignific
ant compared to the cost of medi
