What kind of monitoring is essential during the fumigation process?

Gas concentration monitoring is essential during the fumigation process because it ensures the safety and effectiveness of the fumigation operation. Monitoring the concentration of the fumigant in the air helps to verify that the correct dosage is maintained throughout the treatment area, ensuring that the targeted pests are adequately controlled. It also helps prevent hazardous situations for workers and the surrounding environment by ensuring that gas levels do not exceed safe thresholds.

Other monitoring types, such as air pressure, humidity, and temperature, can play supportive roles in the overall fumigation process, but they do not directly measure the critical factor of fumigant efficacy and safety as gas concentration does. Ensuring that the correct gas concentration is maintained is paramount, as inadequate levels may result in ineffective pest control, while excessive levels may pose health risks.
