Pesticide Safety and your Behavior
Montana State University
Pesticide Safety Education Program
2010
Evolution of Pesticide Safety
DDT!
Biomagnification
Precipitated EPA Civil and Criminal Penalties Punishments for violations.
Fines Loss of license incarceration
Examples Selling a RUP to a person not certified Giving pesticides away Use a pesticide inconsistent with its label Altering a pesticide label Failure to keep records or allow inspection
LAWS versus Safety
Examples of what veteran applicators see in the field
Do you see any problems with this picture?
What is the final and 4th mode of entry of pesticides?
Mode of Entry
Have you smoked or taken a pinch of chew during a pesticide application?

0of5
Compare yourself to previous surveys across Montana. 1/5 applicators surveyed smoked or chewed during application
of pesticides in Montana. Chewing and smoking while applying pesticides increases exposure to pesticides and may result in pesticide poisoning.

Compare yourself to previous surveys across Montana.
Alarmingly, 25% of applicators surveyed ingested food while applying pesticides without washing hands prior! This increases exposure dramatically and may be extremely dangerous. This may lead to acute or chronic pesticide poisoning.

in their career while repairing spray equipment. 9% never wore gloves to begin with.

ABC’s of exposure
Are you being exposed to pesticides by not wearing PPE?
Can you transfer this to your family?
OK, you are contaminated.So what!How toxic is it?
Reading the product label can help you!
*It can minimize risk towards yourself or your family.HOW DO YOU FIND OUT
HOW TOXIC YOUR PESTICIDE PRODUCT IS?
Signal Word
SIGNAL WORD = Acute Toxicity
Acute Toxicity Testing is required by the Environmental Protection Agency for: Each active ingredient For inert ingredients
Usually uses rats over a short period of time Very expensive process
LD50
Lethal dose at which 50% of a given population develops lethal effects Expressed in parts per million
You have an LD50 of 100 parts per million with one chemical and a LD50 of 10,000 parts per million with another.
Which one is more toxic?
100 parts per million; takes less to produce a toxic effect
Signal Words / LD50
Caution (Category IV) You can drink the stuff
Table 2. Signal words found on pesticide labels.
Gordon Shrum – Cochair BC Hydro
Agent White Compound
Agent Orange
4:1 mixture of 2,4-D and picloram
1:1 mixture of 2,4-D and 2,4,5-TProduces dioxins – carcinogen
The National Toxicology Program has classified TCDD to bea human carcinogen, frequently associated with soft-tissue sarcoma, Non-Hodgkin's lymphoma, Hodgkin's disease and chronic lymphocytic leukemia (CLL).
1896 – 1985!
Chronic Toxicity
Long Term Exposure Many repeated low dose exposures
Definition EPA mandates testing for chronic toxicity of:
Active ingredients Usually on rats This is very expensive Chronic toxicity statements are placed on the product label
(carcinogen, mutagen, reproductive damage, etc..)
Some of our “Safest” chemicals
Chronic Affects Evident Immune system problems Sores, Rashes

Compare yourself to previous surveys across Montana. 31% of private applicators surveyed have been at least mildly poisoned
by unnecessary exposure to pesticides. Always minimize bad habits while wearing recommended PPE to minimize exposure.
Do you wear PPE that is required on the product label while applying pesticides?

RespiratorsRead Product Label Particulate masks (dusts, granules)
The one-strap dust mask is not NIOSH approved. When pesticide label recommends a dust filter this is not acceptable. For nuisance-level dusts.
Generally, two-strap respirators with exhale valves are not for pesticide
spraying but are acceptable for application of pesticide dusts and granules.
Always read the pesticide label for product-specific recommendations.
Cartridge Type Respirators (pesticide vapors) Fitted face piece and replaceable filters Not for fumigants Prefix of NIOSH/MSHA “TC” Cartridges should be replaced annually and stored in ziplock bags Cartridges usually labeled for use with ORGANIC VAPORS Follow product label
