What is the correct procedure when filling a spray tank with water and agrichemical concentrate?
Answer: Fill the tank half full with water, add the chemical, then top up with water
Filling half with water first ensures the concentrate is immediately diluted, reducing the risk of splashing or reacting with undiluted chemical when topping up.
What is the three-rinse method used for in agrichemical handling?
Answer: Emptying and cleaning agrichemical containers before disposal
The three-rinse method involves rinsing an empty container three times with water and adding the rinse water to the spray tank, ensuring all residue is removed before container disposal.
What is an induction hopper primarily used for when loading agrichemicals?
Answer: Safely adding powders and liquids to the spray tank without direct tank opening contact
An induction hopper allows operators to safely load concentrated agrichemicals into the spray tank via a dedicated inlet, reducing exposure to concentrated product.
Before mixing two different agrichemicals together in a tank mix, what must you always check?
Answer: That the products are compatible with each other
Checking compatibility is essential because incompatible agrichemicals can react together, causing loss of efficacy, physical separation, equipment damage, or hazardous reactions.
What does an anti-siphon device on spray equipment prevent?
Answer: Spray mixture or chemical from flowing back into the clean water source
An anti-siphon device prevents spray mixture from back-flowing into the water supply, protecting dams, tanks, and waterways from agrichemical contamination.
Where is the most appropriate place to mix and load agrichemicals on a NZ farm?
Answer: On a sealed, bunded pad located away from waterways and drains
A sealed, bunded pad captures spills and prevents them from contaminating soil, groundwater, or waterways, which is a requirement under NZ environmental legislation.
What is the correct first response if you accidentally spill agrichemical concentrate during mixing?
Answer: Contain the spill and absorb it with suitable absorbent material, then dispose of safely
Containing and absorbing a spill prevents it from spreading to soil or waterways; using water to wash away a spill simply spreads contamination over a wider area.
