Which of the following practices is essential in the air-monitoring plan for fumigation?

Taking air samples at set intervals is essential in the air-monitoring plan for fumigation because it allows for consistent and reliable data collection regarding the concentration of fumigants in the environment. Regular sampling helps ensure that exposure levels are maintained within safety thresholds, providing critical information about the effectiveness of fumigation and the safety of workers. By adhering to a schedule, it is possible to identify trends, detect any potential spikes in fumigant levels, and respond more quickly to any hazardous situations that may arise. This systematic approach is vital in ensuring that safety protocols are actively monitored and enforced during fumigation operations.
