CFA Safety and Environmental Protection 3

Question 1

Which federal agency regulates the labeling and registration of fertilizers that contain pesticide claims in the United States?

Accepted Answer

EPA

Answer

The EPA regulates any product with pesticidal claims under FIFRA, and fertilizer-pesticide combination products must be registered with the EPA before sale.

Question 2

When a worker experiences skin contact with anhydrous ammonia fertilizer, the immediate first aid response is to:

Accepted Answer

Flush with large amounts of water for at least 15–20 minutes

Answer

Anhydrous ammonia causes severe alkali burns; flushing immediately with large amounts of water dilutes and removes the chemical to minimize tissue damage.

Question 3

The nitrogen loss process called volatilization is most significant when urea fertilizer is applied to:

Accepted Answer

Warm, moist soils with a high pH and no incorporation

Answer

Urease enzyme activity is highest on warm, moist, high-pH soils, rapidly converting urea to ammonia gas that escapes to the atmosphere before incorporation.

Question 4

Which type of soil test result would indicate the LOWEST risk of phosphorus runoff loss?

Accepted Answer

Soil phosphorus at 15 ppm on a well-structured silt loam with buffer strips

Answer

Low soil phosphorus levels, good soil structure, and vegetated buffer strips all combine to minimize phosphorus runoff risk to adjacent waterways.

Question 5

OSHA's Hazard Communication Standard (HazCom) requires that workers who handle fertilizers have access to:

Accepted Answer

Safety Data Sheets and receive training on chemical hazards

Answer

HazCom (29 CFR 1910.1200) requires employers to provide SDS for all hazardous chemicals and train employees on how to interpret and use hazard information.
