Pesticide Classifications


Restricted Use – may cause unreasonable adverse
effects to the environment or humans, even if used as
directed.
Unclassified – usually no adverse effects if used as
directed.
Commercial Applicator License
Formulations
Pesticide Toxicity

Refers to the ability of a pesticide to cause acute or
chronic injury

Hazard = Toxicity X Exposure

Ex. Gasoline and Aspirin
Types of Toxicity



Acute – usually immediate, obvious,
reversible
Delayed – “chronic”, usually from repeated
doses
Allergic – immune system response to
chemicals
Acute Effects

Oral – examples: burned mouth, sore throat,
upset stomach

Inhalation – examples: pain or tightness in chest

Dermal (skin) – examples: itching, blisters, rash

Ocular (eyes) – examples: irritation, temporary
or permanent blindness
Chronic (delayed) Effects
May appear long after exposure:
Tumors
Gene effects
Miscarriage
Impotence
Birth defects
Infertility
Sterility
Nervous system disorders
Types of Allergic Effects

Systemic – as asthma, shock

Skin irritation – rash, blisters, sores

Eye and nose – itchy/watery eyes, sneezing

Will occur with every exposure to the offending
chemical
How Pesticides Enter the Body
Dermal Exposure:
1.
not wearing protective clothing
2.
not washing hands
3.
spilling or splashing
4.
spray or dust drift
5.
windy applications
6.
touching treated plants, soil, livestock
Eye Exposure
1.
Rubbing eyes after use
2.
Splashes
3.
Not wearing eye protection
Oral Exposure
1.
Splashes
2.
Eating, drinking, smoking before washing up carefully
Inhalation Exposure
1.
Working in poorly ventilated areas
2.
Handling dusts or powders
3.
Exposure to drift
Areas of Absorption
Absorption is not
equal over the body
so make sure to
protect yourself!
Poisoning Signs and Symptoms



Mild = fatigue, headache, dizziness, blurred vision, excessive
sweating, nausea, vomiting, stomach cramps
Moderate = inability to walk, weakness, chest discomfort, pupil
constriction, all of the above, just more severe
Severe = unconsciousness, severe pupil constriction, muscle
twitching, running nose, breathing difficulty, coma, death
Prevention and Preparation







Read the label and follow it to the very last word!
Always keep a change of clothes nearby
Always keep soap nearby
Make sure a water source is present whenever contact with pesticides is possible
Check containers for leaks or cracks before handling.
Don’t work alone if possible in case of accident
Keep emergency phone numbers close by.
Emergency Procedures
Depending on the type and degree of exposure:






Call poison control center, 911, or take victim to a hospital WITH
THE LABEL OF THE PESTICIDE!
Look at the label for emergency directions
Remove any contaminated clothing
Wash (with soap) any affected areas of your body immediately
If pesticide gets in eyes, rinse eyes out thoroughly
If possible remove the victim from the contaminated area
Alabama Poison Center


Calling the
Alabama Poison Center
is as easy as dialing
1-800-222-1222

Storage





Choose somewhere away from sensitive areas, that’s not
prone to flooding and accessible only to authorized
personnel.
The site should be cool, dry, fire-resistant, have
preventative measures in place, and have absorptive
materials (clay, cat litter, activated charcoal..) and tools
to clean up spills.
Signs should be in place on or around the structure saying
“Danger, Pesticides”.
Pesticides should be arranged in an organized way so they
don’t cross contaminate, or be confused for another type.
The labels should always be visible.
Disposal

Labels will indicate how to best dispose of the
product you have.

Remember the label is the law!

Triple – rinse

Depending on what type
of pesticide you used,
containers can be
burned, taken to a
landfill, or returned
to the manufacturer
In Case of Spills……..








Give first aid if needed
Block off the area and put up a warning sign
Use absorbent material to soak up the spill
Shovel material into a leak-proof container
Dispose of it as you would excess pesticides
(you may have to call the manufacturer)
Do not hose down the area, it will cause the chemical to spread.
You may be able to use bleach, ammonia or lye on it to stop the
chemical action.
If it’s a major spill, call the manufacturer for help, the National
Agricultural Chemicals Association Pesticide Safety Team Network,
and even local authorities if the spill happened on or near a public
highway.
