Commodity Fumigation License Practice Exam

Which type of fumigant applicator does not require calibration?

1. Pressurized tanks

2. 1 or 2 lbs seamless cans

3. Gas masks

4. Mechanical foggers

The correct answer is: 1 or 2 lbs seamless cans

The correct answer highlights that 1 or 2 lbs seamless cans of fumigants do not require calibration. This is because these cans are designed for straightforward application without the need for complex measurement adjustments. Each can contains a predetermined amount of fumigant, allowing the applicator to use it directly as it is intended, eliminating the need for calibration instruments or setup processes that are often required for other types of equipment. In contrast, the other options generally involve equipment that either disperses fumigants over a broader area or requires specific adjustments to ensure accurate application rates. For instance, pressurized tanks and mechanical foggers are typically reliant on precise flow rates and pressures, necessitating regular calibration to ensure effective and safe use. Gas masks, while essential for the safety of the applicator, serve as personal protective equipment rather than tools for applying fumigants, making calibration irrelevant to their function. Therefore, the seamless cans stand out as the only option that simplifies the application process by not requiring calibration.
