✔✔Regulated and unregulated - ✔✔One of the classifications of pesticides under
FIFRA.
✔✔Unclassified use and restricted-use - ✔✔One of the classifications of pesticides
under FIFRA.
✔✔Tolerance as set by the EPA - ✔✔The maximum amount of pesticide residue that
may legally remain on or in a commodity at the time of harvest or slaughter.
✔✔Section 18 under FIFRA - ✔✔Allows the use of an unregistered pesticide to control
an 'emergency' pest problem.
✔✔Microencapsulates - ✔✔A type of formulation that covers either a liquid or dry
pesticide particle with plastic.
✔✔Adjuvants - ✔✔Substances that are either premixed in the pesticide formulation or
added to the spray tank mixture.
✔✔Stickers - ✔✔A type of adjuvant that increases the adhesion of solid particles to
target surfaces.
✔✔Hazard = toxicity x exposure - ✔✔The equation that reflects the relationship
between pesticide safety concerns.
✔✔LD50 and LC50 - ✔✔Measures acute toxicity.
✔✔Hazard Class II - ✔✔Associated with the signal word that indicates a small to
medium dose could cause death, illness, or skin, eye, or respiratory damage.
✔✔DANGER—POISON - ✔✔A signal word associated with Hazard Class II.
✔✔DANGER - ✔✔A signal word associated with Hazard Class II.
✔✔WARNING - ✔✔A signal word associated with Hazard Class II.
✔✔CAUTION - ✔✔A signal word associated with Hazard Class II.
✔✔Maximum pesticide residue - ✔✔The legal limit of pesticide residue allowed on or in
a commodity.
, ✔✔Emergency pest problem - ✔✔A situation that may allow the use of an unregistered
pesticide under Section 18 of FIFRA.
✔✔Pesticidal activity - ✔✔The ability of a substance to act as a pesticide.
✔✔Spray application problems - ✔✔Issues that may arise during the application of
pesticides.
✔✔Compatibility agents - ✔✔A type of adjuvant that helps improve the mixing of
different pesticide formulations.
✔✔Cholinesterase levels - ✔✔If cholinesterase levels fall significantly below baseline,
remove the pesticide handler from pesticide exposure until such time as the
cholinesterase level builds back up again to normal levels.
✔✔Dermal exposure to pesticide - ✔✔The first objective if dermal exposure to a
pesticide has occurred is to rinse the pesticide off to prevent absorption.
✔✔Inducing vomiting for oral pesticide exposure - ✔✔Before inducing vomiting, first
give the victim at least 2 glasses of water to dilute the product.
✔✔PPE for pesticide application - ✔✔During an application if large amounts of a
pesticide could be deposited on your clothing over an extended period of time, wear a
chemical-resistant suit made of rubber or plastic.
✔✔Wearing gloves and footwear - ✔✔The appropriate way to wear gloves and footwear
for a job in which you will be working with your arms raised some of the time and
lowered some of the time is to wear gloves with a cuff closed tightly outside the sleeve
and wear your pant legs outside your boots.
✔✔Respiratory protection - ✔✔Filters are classified on the basis of oil degradation
resistance and filter efficiency.
✔✔Filters - ✔✔Classified on the basis of oil degradation resistance and filter efficiency.
✔✔Reusable PPE Replacement - ✔✔Glove replacement is a high priority.
✔✔Contaminated Clothing Disposal - ✔✔Discard such items in a hazardous waste
collection site.
✔✔Preventing Water Contamination - ✔✔Select pesticides that tightly adsorb to soil
and are not persistent.
