This Standard contains requirements for the protection of agricultural workers on farms, forests, nurseries and greenhouses, and handlers of agricultural pesticides. It contains requirements for training, decontamination, notification, and emergency assistance. It also contains specific instructions and exceptions pertaining to the statements on this label about personal protective equipment (PPE), and restricted entry interval. The requirements in this box only apply to uses of this product that are covered by the Worker Protection Standard.
Do not enter or allow entry into treated areas during the restricted entry interval (REI) of 12 hours.
PPE required for early entry to treated areas that is permitted under the Worker Protection Standard and that involves contact with anything that has been treated such as plants, soil or water is : coveralls, chemical-resistant gloves such as barrier laminate or butyl rubber or nitrile rubber or viton, shoes plus socks and protective eye wear.

Non-agricultural use requirements
• If WPS does not apply, then follow these instructions
Storage and disposal• How to best store
and dispose of product and/or product container
WPS safety concept: pesticide hazards
• Hazards of pesticides resulting from toxicity and exposure, including:
– Acute effects– Chronic effects– Delayed effects– Sensitization
Hazard = Exposure x Toxicity
• High exposure90% = 100% x
90
• No exposure0% = 0% x 90
How can pesticide exposure occur?

ApplicationPlant residues
Mike White, Iowa State University
Three farm workers gave birth to infants with birth defects. Environmental Health Perspectives, 2007, ehponline.org
Insecticide: farm worker applied a carbamate insecticide for several days. He became nauseous, dizzy, weak, and had a headache. Michigan pesticide surveillance report, 2005
Herbicide: a worker was spraying glyphosate, the end of the hose came off and some sprayed on his mouth. He became nauseous and vomited. Michigan pesticide surveillance report, 2005
Fungicide: farm worker mixing fungicide rested his arm on a spill, it became red, irritated, and very itchy.
Michigan pesticide Surveillance report, 2005
Toxicity is…..
• The potential of a chemical to be poisonous
• Expressed as LD50
– Lethal dose for 50% of the population
Signal wordsSignal Word Toxicity Oral Lethal Dose
(Human, 150 lbs.)Caution Low toxicity 1 ounce to more than
a pint
Warning Moderately toxic 1 teaspoon to 1 tablespoon
Danger Highly toxic Few drops to 1 teaspoon
Danger-Poison
Highly toxic to humans
Few drops to 1 teaspoon
Acute toxicity
• High level, one time exposure
Chronic toxicity
• Effects are not seen until much later
• Result of repeated exposures
Chronic toxicity can cause• Cancer• Tumors• Birth defects• Infertility or sterility• Impotence• Blood disorders• Brain damage• Paralysis• Emphysema,
asthma• Kidney problems
Sensitization
• Gradual development of allergic reaction to pesticide
WPS safety concept: routes of entry
• Routes by which pesticides can enter the body

• Most common route that children are poisoned
• Mixing and loading in a confined area
Inhalation exposure
Ocular exposure
• Rubbing eyes with contaminated hands or clothing
• Immediate absorption

Oral exposure
• Rinse mouth with water• Do not induce vomiting
if– victim is unconscious– having convulsions– petroleum based product– corrosive pesticide– label specifies NOT to
induce vomiting
PE
STIC
IDE
Inhalation exposure
• Remove to fresh air• Loosen tight clothing • Keep air passages
clear• Perform artificial
respiration if necessary
Eye exposure
• Wash eye with a gentle stream of clean water for 15+ minutes
• Get medical attention if there is pain or reddening of the eye
Obtaining medical care
WPS safety concept: obtaining emergency
medical care• How to obtain emergency medical
care
If you suspect poisoning
1. Contact a doctor immediately
2. Tell what pesticides were being used and the EPA registration number
3. Take labels along if medical care is needed

WPS safety concept: handling pesticides
• Safety requirements for handling, transporting, storing and disposing of pesticides, including general procedures for spill cleanup
Transporting pesticides
• Not inside closed vehicle with people
• Not with food or feed• Tied down and secured
Joyce Hornstein, Iowa State University
Protect sensitive areas from pesticides
• Avoid spraying near:– Beehives, water bodies, houses,
urban areas, sensitive crops
• When spraying:– Not on windy days– Downwind from sensitive areas– Early morning when people & pets
are not present
Cleaning instructions• Refer to pesticide labels and
sprayer manual on how to properly clean sprayer
• Check the label for special cleaning instructions and warnings of sensitive crops affected by tank contamination
Disposal of excess mixed pesticide and rinsate
• Apply on an area listed on the label
• May be applied to sprayed area as long as the total of both applications doesn’t exceed label rate
Storage of pesticides
• Store separately in a locked, labeled, vented cabinet, room, or building
• Inform others of pesticide hazards
• Maintain a list of your pesticides
Storage area safety equipment
• Water supply• Soap• Eyewash bottle• Fire
extinguisher• Absorbent
material
• Shovel• Broom• Dustpan• Trash can
Store pesticides in their original containers
• If a container is broken, leaking, or torn, put the contents into a similar bottle, jug, or bag
• Transfer the old container’s label onto the new one or get a replacement label from your dealer
• Applies only to end user applicators
Pesticide containers
• It is unlawful in Iowa to sell or distribute a pesticide except in the registrant’s or manufacturer’s unbroken immediate container that contains the pesticide product label
Disposing of surplus pesticides
• Contact other possible users– Do not give RUPs to person that is not
certified to apply them
• If legal, use product up according to label directions
Cleaning empty containers
• Triple rinse• Pressure rinse: Rinse with
specialized nozzle for 30 seconds• Gently tap bags and other dry
formulation containers to dislodge remaining product
