potential for movement to water
impact on non target
pesticides that accumulate in animal tissue

has a short half-life
What soils would most likely result in ground water contamination
soils with high sand contents
What is not a practice to prevent harm to non-target animals
not disposing of poisoned rodents
What is wrong with filling a spray tank as shown above
pesticide contaminated water could flow backwards through the hose and contaminate water supply
what site condition could lead to concerns of pesticide run-off into water sources
land with high slop and changes in elevation
What are three good practices that reduce spray drift
check weather conditions
avoid using higher spray pressures than recommended
selecting the coarsest nozzle type
What is always true about cartridge respirators
make sure it is approved for the type of pesticide u are using
if a pesticide label does not specify what type of chemical resistant glove to use, what type should u use
butyl rubber
what information should you use to determine the need for a cartridge respirator when applying a pesticide
the pesticides toxicity, exposure, duration of exposure
why should PPE be worn when applying or handling pesticides
prevent penetration through skin
prevent penetration through eyes and respiratory system
prevent pesticide from being spread in the environment
how often should protective gloves and boots be washed with soap and water?
daily
In addition to what is normally worn when applying any pesticide what extra PPE should be worn when performing s spray application for several hours or days over a one month period using a pesticide with the hazard warming words “Danger-poison”
Cartridge respirator
What are three considerations that affect choice of PPE
label warnings and instructions
amount of exposure
application methods
Which level of protection provides the greatest protection for the pesticide applicator
chemical resistant material
Eye protection points to remember include
eye glasses and safety glasses do not provide enough protection
contact lenses do not provide any eye protection
if u wear glasses, use a style of goggles that fit over them
Should one avoid washing PPE?
NO
what are three examples of a safe attitude toward working with pesticides?
consistently applies safe work practices
emphasizes training and knowledge
insists that safe procedures be followed at all times
