Which of the following is the CORRECT procedure for triple-rinsing a pesticide container?
Answer: Fill 1/4 full with water, shake, drain into mix tank; repeat 3 times
Triple rinsing requires filling the container about 1/4 full with water, shaking or rolling it, then draining the rinse water into the spray tank — repeated three times.
When storing pesticides on shelving, which containers should be placed on the lowest shelves?
Answer: The heaviest and largest containers to reduce fall risk
Heavy and large containers should be stored on lower shelves to reduce the risk of them falling and breaking, which could cause a dangerous spill.
What action should be taken if a pesticide is ingested accidentally?
Answer: Call Poison Control (1-800-222-1222) and follow label first aid instructions
Immediately call Poison Control and follow the label's first aid instructions, as some pesticides cause more harm if vomiting is induced (e.g., petroleum-based products).
Which pesticide storage practice helps prevent vapor buildup that could create fire or health hazards?
Answer: Providing adequate cross-ventilation with vents near the floor and ceiling
Cross-ventilation with vents at floor and ceiling levels allows heavier-than-air vapors to exit at floor level and lighter vapors at ceiling level, preventing dangerous accumulation.
A pesticide label lists the pre-harvest interval (PHI) as 14 days. What does this mean?
Answer: The crop cannot be harvested until at least 14 days after the last application
The pre-harvest interval (PHI) is the minimum number of days that must pass between the last pesticide application and crop harvest to ensure residues decline to safe levels.
Which statement about storing herbicides with insecticides or fungicides is TRUE?
Answer: They should be stored separately to prevent cross-contamination from leaks or vapors
Herbicides should be stored separately from other pesticides because even trace cross-contamination or vapor transfer can damage non-target crops when the contaminated product is applied.
What is the MOST appropriate action when a pesticide spill occurs on skin?
Answer: Immediately remove contaminated clothing and rinse skin with large amounts of water
Immediately remove contaminated clothing and flush the affected skin with large amounts of water for at least 15 minutes to minimize dermal absorption of the pesticide.
