What precaution should be taken during routine nozzle changes and switching spray configurations?

Wearing proper personal protective equipment (PPE) is crucial during routine nozzle changes and switching spray configurations because these tasks may expose the operator to harmful chemicals or biological agents. PPE, which may include gloves, goggles, masks, and protective clothing, helps minimize the risk of direct contact with pesticides or other substances that could be hazardous to health.

During nozzle changes, the operator is often in close proximity to the spray system, which is why proper protection is necessary to prevent exposure. Additionally, the physical act of changing nozzles can lead to splashes or spills, thereby increasing the need for adequate safeguards.

In contrast, performing these tasks without gloves or not ensuring that equipment is off could increase the risk of exposure to chemicals. Changing nozzles during high winds can lead to drift, which not only poses environmental risks but also increases the risk of inhalation or contact with the chemicals being handled.
