Gives you toxicity category
Signal Words
Danger-Poison (I) – Very High Toxicity
•Danger (I) – High Toxicity
•Warning (II) – Moderate Toxicity
•Caution (III) – Low Toxicity
•Caution (IV) – Relatively Nontoxic
CAUTION
What does this mean?
PPE
Chronic Toxicity
•The delayed effects of repeated
exposures over a long period of time.
•Effects evaluated in the lab include
– Potential tumors
– Birth defects
– Reproductive effects
Agricultural
Use
Requirements
Protect Yourself!
4 modes of entry
Oral
Dermal
– Cuts and Abrasions
Respiratory
Eyes
Good Practices
Sound Personal Cleanliness
Dermal Protective Garments
Respiratory Devices (if needed)
– It is LAW to wear minimum PPE stated on
label.
Take it slow and consider:
– Weather (heat, precip.)
– Hazards
PPE
Coveralls
Chemical Resistant Suits, Gloves,
Footwear, Aprons, and Headgear.
Protective Eyewear
Respirators
Coveralls (Types of Fabrics)
Wovens
Unwovens
Coated / Laminate
Wovens
Wovens (Low Toxicity – Granulars, Dusts;
Caution)
– Blue Jeans, Cotton Coveralls
– Absorb Chemicals
For Toxicity Class III or IV–>CAUTION
Cotton (tight weave), Kleenguard®coveralls
Pants or Coveralls
– Beware of rips in garments
Reusable
Nonwovens
•For Toxicity Class (II)–>?? Warning
Nonwovens (Low Toxicity – Liquid,
Granulars, Dusts, Powders) (Warning)
– Synthetic Materials
Tyvek, Comfort-Gard, Kleenguard LP,
Tyvek QC, Saranex
Coated / Laminate Suits
Danger
For Toxicity Class I
PVC, Nitrile, Rubber
Tychem®
– sealed seems.
Non-breathable
Do not use rain suits
with cotton liners
Gloves
Want unlined gloves!
Nitrile, Neoprene, PVC
Do Not Wear Leather
Gloves!
Do Not Wear exam
gloves!
Check for holes often!
Want 14 mils or higher!
Relative Costs - 2002
Nitrile–Good overall protection, $2.39/pr
•Neoprene–Softer, better dexterity-$5.16
•Natural Rubber–Use only on dry or water
based formulations -$11-18.00/pr
•Butyl–For High Toxicity Pesticides-$18.45
•PVC –Anyhydrous ammonia-$4.00/pr
•Viton–Superior Protection but$174.50/pr
Head and Neck Covering
Straw Hat?
Ball Cap?
Hard Hat?
Hoods??
Beware of sweat bands with hats which
cause continuous skin contact
Hoods
Never use permeable materials
If hood is made of non-permeable
materials – Yes (Tychem Hood, Tyvek
Hood)
Hood offers no openings for pesticides to
seep in.
Eyewear
Goggles
Face Shields
Safety Glasses
But never wear
contacts when
spraying
pesticides!!!
Respirators
Read Specimen Label
Cartridge
– Fitted facepiece and replaceable filters
– Not for fumigants
– Prefix of NIOSH/MSHA “TC”
Supplied Air
– Fumigants or life threatening atmospheres
Critical Respiratory Scenario’s?
Pesticides are formulated
Pouring into a sprayer tank
Operators exposed directly to dusts,
sprays, or aerosals.
Fits TEST
(ALWAYS!)
Positive Pressure Test
– Close exhalation valve and exhale
Negative Pressure Test
– Close off the inlet opening of the cartridge by
covering with your palm
Inspect PPE
Make sure you have no smells
– What should you do?
Cartridges expired; renew every year
Is it clean and has it been cleaned?
Decontamination
Always clean your re-usable PPE, this
includes
– Nitrile Gloves
– Goggles
– Laminated Coveralls
– Do not reuse Tyvek coveralls if used on
Category Warning or Danger chemicals.
How
Varies according to what you spray and what your PPE is.
Mix heavy duty soap and hot water in bucket
Throw all contaminated clothing in plastic bag. Keep all gloves on
while taking off clothing.
Dip hands with gloves in bucket, wash eye goggles, and manually
clean respirator.- Put away to dry
With Gloves on take suit off and discard, place in washer, or cleaned
with a brush (coated / laminate).
Dip hands with gloves again then dip foot wear and discard. Then
clean up area (bucket, tailgate). Then clean gloves and discard.
Beware of washing in washer..(separate washer daily and with hot
water and extra rinse cycle)
Storage
Store in a clean dry place away from
pesticides and containers.
Avoid direct sunlight and high
temperatures.
First Aid and Emergency Situations
Speed is the key factor, but consider:
– Is victim breathing?? Artificial Respiration?
– Decontaminate the victim
– Heatstroke or Chemical Contamination
– Call a physician or 911.
First Aid - How
Read Pesticide Label for Special First Aid
Instructions
Always call a physician or 911
Remove victim from contaminated environment.
Clean contaminate from individual if evident
Do not contaminate yourself with mouth to
mouth contact / clean
Save pesticide container
Specific Treatment
Skin
– Drench skin and clothing with water
– Remove clothing
– Clean skin and hair thoroughly with soap and
water
– Dry and wrap in blanket
continued
Eye
– Hold eyelids open, wash eyes with gentle stream of
clean running water immediately. Don’t delay
– Wash for 15 minutes or more.
– Do not use commercial eye washes.
Inhaled Poisons
–
–
–
–
Do not go in without respirator
Carry victim to fresh air
Loosen all tight clothing
If convulsing, protect him/her from falling and striking
head.
continued
Swallowed Poisons
– Call a physician
– Do not induce vomiting unless a noncorrosive
substance has been swallowed (not Lye,
acids, Lysol)
– Initiate gag reflex. Place victim face down.
– Get to hospital
– If corrosive give milk or water
continued
Chemical skin burns
– Remove contaminated clothing
– Wash with large quantities of water
– Cover with clean cloth or blanket
– Get to hospital
Heat Stress
Pesticide users are
at higher risk…
More clothing
Toxic environments
Other stress factors
Hard work
More exposed to
sun
Difficult to drink
water
Heat Stroke
Body's thermoregulatory system stops working.
•Many of the symptoms are the same as for heat
exhaustion.
•But there are additional symptoms
–cessation of sweating
–difficulty walking
–disorientation and fainting or;
–unconsciousness
Heat Stoke Points to Consider
Heat Stroke can permanently damage
your health
If you get heatstroke once, you may be
likely to get it again.
First Aid
Key symptom to look for is disorientation. A person who is
functioning well mentally isn't in danger. Someone who's becoming
"jelly brained“is in trouble.
Stop what you are doing and get out of the sun-preferably into an airconditioned building.
•Pack ice around the patient’s neck, armpit and groin.
•Splash water on the skin, and fan them.
•Elevate the legs.
•If the person is conscious, give plenty of fluids--1 to 2 quarts-preferably a sports beverage, but water's fine.
•The person will probably be nauseated and may not want to drink
anything, but fluids are essential.
•If you don't feel better within 30 minutes, go to a hospital emergency room.
•Heat Stroke is generally not fatal but heat stroke can be!!
