CFA Safety and Environmental Protection Questions and Answers

Question 1

An applicator is loading liquid UAN (28-0-0) into a sprayer tank when a hose ruptures, causing a significant spill onto a concrete containment pad.
What is the IMMEDIATE first priority for the applicator?

Accepted Answer

Stop the flow of the fertilizer from the source.

Answer

Use absorbent materials to clean up the spill.

Answer

Notify the state environmental agency.

Answer

Wash down the pad with water to dilute the spill.

Question 2

When handling anhydrous ammonia (82-0-0), which piece of Personal Protective Equipment (PPE) is most critical for protecting the applicator from severe chemical burns and respiratory damage?

Accepted Answer

Non-vented chemical splash goggles and ammonia-rated rubber gloves.

Answer

Leather gloves and standard safety glasses.

Answer

A disposable dust mask and cloth coveralls.

Answer

Steel-toed boots and a hard hat.

Question 3

To protect surface water quality from nutrient contamination, which of the following is a critical best management practice when applying fertilizer near a river?

Accepted Answer

Establish and observe a mandatory no-application setback or buffer zone.

Answer

Apply fertilizer directly up to the riverbank to treat the riparian zone.

Answer

Increase the application rate to ensure rapid crop uptake.

Answer

Ensure the spreader is turned off when crossing the river on a bridge.

Question 4

A facility stores liquid fertilizer in multiple large above-ground tanks. To comply with environmental regulations and prevent groundwater contamination in case of a tank failure, what structural feature is required?

Accepted Answer

Secondary containment capable of holding at least 110-125% of the largest tank's volume.

Answer

A chain-link fence with a locked gate for security.

Answer

An overhead roof to prevent rainwater from contacting the tanks.

Answer

A concrete foundation pad sloped away from all tanks.

Question 5

Certain fertilizer materials, such as ammonium nitrate, are regulated by the Department of Homeland Security. Why is this specific fertilizer of particular concern from a safety and security standpoint?

Accepted Answer

It can be misused as a component in the manufacturing of illegal explosives.

Answer

It has an extremely high salt index that can burn crops.

Answer

It is highly corrosive to all metal application equipment.

Answer

It readily leaches into groundwater as nitrate.

Question 6

Which of the following environmental conditions creates the HIGHEST risk for significant nitrate (NO3-) leaching into groundwater following a nitrogen fertilizer application?

Accepted Answer

Sandy soil with low organic matter followed by heavy rainfall.

Answer

Heavy clay soil with poor drainage during a dry period.

Answer

Silt loam soil with high organic matter during a period of warm, windy weather.

Answer

Frozen, sloped ground with a significant snowpack.
