Since category III chemicals are included in this law
and category IV are not, it is essential that you know
which is which.
The CFL web site is your best source of information
on the categories.

Pesticide Toxicity: Routes of Exposure
Eye
 Dermal – skin
 Oral - by mouth,
ingestion
 Inhalation breathe in

13
PPE = Personal Protective Equipment
Follow label
instructions
14
To Reduce Exposure, Do Not:




15
Have contact with pesticides in closed or poorly
ventilated areas or breathe vapors, dust or mist
without PPE Be especially aware of fumigant vapors
Inhale vapors from drift or reenter area too soon
Splash or spray pesticides in eyes or mouth
Rub eyes or forehead with contaminated gloves or
hands
 Mistake pesticide for food or drink
 Apply pesticides in windy weather
 Touch pesticide treated surfaces
To Reduce Exposure, Do:




16
Use PPE as indicated on label when
preparing or applying pesticides
Wash contaminated clothing--check
pesticide label directions
Avoid accidentally applying
pesticides to food
Wash hands after handling
pesticides or containers
To Reduce Pesticide Exposure to
Others, when possible





17
Consider alternatives to pesticides
Use baits, traps and pest strips
Spot treat or use crack and crevice treatments
Make applications at times when staff and
students are less likely to contact pesticides
Promote good sanitation and hand washing
HEALTH RISK =
EXPOSURE X TOXICITY
Reduce risk by reducing either
or both of those factors


18
Exposure -- find non chemical pest
controls, improve pesticide handling
procedures and safety practices
Toxicity – select products with lower
toxicity
Measuring Toxicity




19
Toxicity rating LD50 (inhalation LC50)
Lethal dose that killed 50 percent of
test population (animals exposed to
pesticide)
LD50 expressed in milligrams product
per kilogram weight of animal
Lower number, the higher the
toxicity
