Chapter 2 - CORRECT ANSWERSChapter 2
Ways you may be exposed to pesticide - CORRECT ANSWERS-Dermal -Eye -Respiratory
When is a formal respiratory program needed - CORRECT ANSWERS-When respirators are used -Must
include all requirements outlined in OSHA respiratory protection standard
Problems caused by lateral movement of soil-active herbicides - CORRECT ANSWERS-Particularly bare-
ground treatment -Lateral movement may cause excessive destruction of vegetation and result in soil
erosion or cause injury to desirable vegetation -On sloped areas = erosion -Injury to adjacent areas
Precautions to consider when treating aquatic sites - CORRECT ANSWERS-Use herbicides labeled for that
purpose -Avoid drift -Keep spray out of water -Keep buffer adjacent to aquatic site -Be alert to lateral
movement or runoff -Need special permit
List concerns of livestock owners when ROW crosses pasture land - CORRECT ANSWERS-Herbicide
residue will poison livestock -Active ingredient could appear in meat or milk making commodities
unsellable -Overspray and drift -Make sure pesticide is labeled for use in pasture -Do no apply if labeled
for non-crop areas -Be aware of re-entry times -Wild cherry becomes poisonous after spraying, needs to
be fully removed
Recognize proper methods of preventing back-siphoning of pesticide into water - CORRECT ANSWERS-
Use separate pump with check valves -Don't let filler hose dip into tank -Use back flow devices -Don't
use water source used for domestic purposes or watering livestock
Recognize features of sprayer filling station selected to minimize spills and contamination - CORRECT
ANSWERS-Designed to minimize problems -Not located on pond or stream -Area slopped away from
surface water -Triple rinse containers
Identify who is responsible for cleaning up pesticide spill - CORRECT ANSWERSThe applicator
, Methods for cleaning a spill and decontaminating spill area - CORRECT ANSWERS-PPE -Contain spill -
Isolate area -Call appropriate emergency response -If pest. in soil, remove upper layer -Can use activated
charcoal
Chapter 3 - CORRECT ANSWERSChapter 3
Overspray - CORRECT ANSWERSWhen pesticide is applied directly outside of target area
Problems that arise because of drift - CORRECT ANSWERS-Damage to non-target plants -Contaminate
surface waters -Harm wild or domestic animals or people -Legal matters -Reputation -Costs
Particle Drift - CORRECT ANSWERS-At time of application, small particles move from target area
Vapor Drift - CORRECT ANSWERS-Spray turns to gas and fumes and move from target area
5 Factors that increase particle drift - CORRECT ANSWERS-Droplet size decrease -Wind speed increase -
Nozzle height increase -Temp increase -Humidity decrease
Most important factor affecting particle drift - CORRECT ANSWERS-Spray droplet size
Discuss effects of air stability and temp inversions on particle drift - CORRECT ANSWERS-Don't affect
drift directly but provide conditions where it is more likely to occur -Air stability is warmed at the plant
surface and rises causing currents to move droplets upward. Wind then moves them off site. -Layer of
warm air is sandwiched between layers of cold caused by rapid cooling of plant surface. Lost heat
radiates upward causing air to be warmer above surface. Inversion indicated by fog or smoke at ground
level
Clues that suggest temperature inversion - CORRECT ANSWERS-Ground fog or smoke that move laterally
in concentrated cloud instead of moving upward and dissapating. -Common on clear, calm nights, and
last into the morning
