How frequently should fumigation equipment be calibrated?

Regular calibration of fumigation equipment is essential for ensuring accurate delivery of chemicals and the safety of both the applicator and the environment. The manufacturer's recommendations and safety standards are designed to optimize the equipment's performance and accuracy. Depending on the complexity of the equipment and the specific chemicals used, these guidelines ensure that the equipment functions effectively and maintains compliance with safety regulations.

Calibrating according to these recommendations helps to prevent issues that can arise from under- or over-application of fumigants, which could lead to ineffective treatment or potential hazards. Regular calibration also aligns with best practices in pest management, ensuring that the equipment is always ready for safe and effective use when needed.

Addressing the other options, calibrating every month regardless of use can lead to unnecessary downtime and costs if the equipment is not used frequently. Calibration only when malfunctioning can result in undetected inaccuracies in chemical application, posing safety risks. Lastly, calibrating once a year may not be sufficient depending on the usage frequency and type of equipment, as issues can arise more quickly than an annual check allows for.
