The Alveoli
The alveoli are where the oxygen from the air
enters your blood, and the carbon dioxide from
your body goes into the air. Here contaminants
in the air enter the bloodstream and are rapidly
transported throughout the entire body

Health effects

• Acute inhalation effects
• may burn the entire respiratory tract and lead
  to pulmonary edema
• difficulty in breathing
• may enter blood stream very rapidly upon
  inhalation and have systemic effects

8
Health effects

• Chronic inhalation effects
• Repeated exposure leads to the formation of
  scar tissue.
• This destructs the walls of the alveoli sacs and
  decreases the area for air to be exchanged. Long
  term effects are definite.

Legality

• You are legally required to follow all personal
  protective equipment instructions on the label.
• Pesticide labeling lists the minimum personal
  protective equipment you must wear while handling
  the pesticide.
• Often the labeling lists different requirements
  for different activities. Usually more
  requirements are needed for mixing and loading
  than for application.

Respirators and Physical Fitness

• Medical evaluations
• are required for anyone
• wearing respirators.
• Breathing through a
• respirator is work for the
• body.
• Respirators can be
• hazardous to people
• with heart or lung
• problems.

21
Protect yourself
When used properly, respirators prevent the
inhalation of chemicals and dust and therefore,
offer the best protection.
22
How Respirators Work

• Air movement is
• controlled by
• rubber inhalation
• and exhalation
• valves.
• The adjustable
• straps are used to
• keep the respirator
• snug on the face.

How Respirators Work
When you inhale, air is pulled through the
cartridge, where air contaminants are trapped.

Respirator Use

• Agricultural jobs where respirators are required
• Handling chemicals
• (pesticides, disinfectants)
• Nutrient management
• Cleaning grain bins
• Handling moldy hay or
• silage
• Working in dusty fields

26
Causes of Pesticide Inhalation

• Breathing vapors, dusts, and mists from handling
  pesticides
• Using fumigants and other highly toxic pesticides
• Inhaling mists and vapors from pesticide drift

27
Causes of Pesticide Inhalation

• Working in poorly ventilated spaces
• Using the wrong respirator/cartridge for
  the job
• Using a respirator that fits poorly
• Using cartridges that are spent

28
Typical Applicator Questions

• I must wear a respirator which type is best?
• Arent they all the same?
• Some look differentdoes size matter?
• Are there any significant differences?
• Do I really need a fancy one? Wont a paper dust
  mask work?
