WPS Worker Safety Training
Agriculture
Kristine Schaefer, Iowa State University
What does the Worker Protection Standard
cover?• Pesticides used in production of
agricultural plants
Forests
Farms
Nurseries
Greenhouses
Who does the Worker
Protection Standard
protect?1. Agricultural Workers
2. Early-entry workers
3. Pesticide Handlers
Agricultural workers
• Do hand labor, such as weeding, planting, cultivating, harvesting
Early-entry workers
• Perform special tasks involving anything that has been treated with a pesticide
Pesticide handlers
• Mix, load, apply, clean, or repair equipment
• Perform other tasks in direct contact with pesticides
Joyce Hornstein, Iowa State University
Worker training requirements
• Basic pesticide safety information before entering a pesticide treated area
• Full training before 6th day of work• Training required
every 5 years
WPS safety concept: pesticides
• Where and in what form pesticides may be encountered during work activities
What is a pesticide?
• Substances used to control:
Insects – insecticidesFungi – fungicidesWeeds – herbicides
Betsy Buffington, Iowa State University
Where can pesticides be encountered during work
activity?
What forms of pesticides can be encountered during work
activity?
WPS safety concept: pesticide hazards
• Hazards of pesticides resulting from toxicity and exposure, including:
– Acute effects– Chronic effects– Delayed effects– Sensitization
RISK =RISK = TOXICITYTOXICITY
EXPOSUREEXPOSURE
Toxicity
• The degree or extent to which a chemical is poisonous
Acute toxicity
• Effects from a single exposure over a short period of time
Chronic toxicity
• Effects are not seen until much later
• Result of repeated exposures
Sensitization
• Certain people develop allergic reactions or sensitization to some types of pesticides
WPS safety concept: routes of entry
• Routes by which pesticides can enter the body
Exposure
Pesticides absorbed through
skin
Breathe in vapors or
dusts
Swallowing pesticides;
wiping mouth
Pesticides in eyes; rubbing
eyes
WPS safety concept: signs and symptoms
• Signs and symptoms of common types of pesticide poisonings
Signs and symptoms
• Skin rashes, irritation to nose, throat or eyes
• Nausea, sweating, headache, dizziness, muscle pains, cramps
• Trouble breathing, blurred vision
WPS safety concept: first aid & medical care
• Emergency first aid for pesticide injuries or poisonings
Pesticide on skin
• Rinse with water• Take off clothing
that has pesticide on it
• Wash with plenty of soap and water
Swallowed pesticide
• 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
Breathing in pesticide
• Remove to fresh air• Loosen tight clothing • Keep air passages
clear• Perform artificial
respiration if necessary
Pesticide in eyes
• 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
– EPA safety poster
Safety poster
If you suspect poisoning
1. Contact a doctor immediately
2. Tell what pesticides were being used and the EPA registration number
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: decontamination
• Routine and emergency decontamination procedures
Decontamination supplies
Everyday decontamination
Everyday decontamination
Joyce Hornstein, Iowa State University
Emergency decontamination
• Stop work and leave work area• Remove contaminated clothing• Rinse exposed skin with water right
away• Wash with soap and water ASAP• Provide assistance if necessary• Medical attention may be necessary
Eye flushing technique
• Use eye-wash fountain or pour water in eyes
• Hold eye open while flushing• Move eye ball and eye lid• Flush for minimum of
15 minutes• Seek medical attention ASAP
Betsy Buffington, Iowa State University
WPS safety concept: chemigation and drift
• Hazards from chemigation and drift
Chemigation
• Uses irrigation water to apply pesticides to soils and crops
• Never use irrigation water for drinking or washing
Fws.gov
Pesticide drift
• Leave the area immediately if pesticides are being applied or pesticide drift from a nearby application is moving towards you
WPS safety concept: pesticides on clothing
• Hazards from pesticide residues on clothing
Pesticide residues on clothing
• From brushing up against:– Plants– Equipment– Pesticides
Jim Oleson, Iowa State University
WPS safety concept: taking pesticides home
• Warnings about taking pesticides or pesticide containers home
Do not take pesticides home
WPS safety concept: explanation of WPS requirements that
workers must follow• Notification of application and entry
restrictions• Availability of information about
applications• Protection against retaliatory
acts

Care and maintenance
• Inspect before each use• Replace damaged or worn parts• Properly dispose
of damaged, contaminated or worn out PPE to prevent reuse
Rich McColley, Iowa State University
WPS safety concept: the label
• Format and meaning of information contained on pesticide labels and in labeling, including safety information such as precautionary statements about human health hazards
Early-entry workers only!
Precautionary statements
• Hazards to humans and domestic animals
• Environmental hazards
• Physical or chemical hazards
