What steps should be taken after handling pesticides?

After handling pesticides, it is crucial to prioritize personal safety and hygiene to minimize any potential health risks. Washing hands and exposed skin thoroughly helps remove any pesticide residues that might have come into contact during application. This step is particularly important as it prevents the absorption of chemicals through the skin, reducing the likelihood of adverse health effects.

Changing clothing is also an important action because any contaminants on clothing can continue to pose a risk of exposure even after the pesticide handling has ceased. By changing into clean attire, you effectively lower the risk of bringing pesticides into other areas, which is essential for ensuring safety in both personal and communal environments.

The other options presented do not align with best practices for safety after handling pesticides. Leaving contaminated clothing on can lead to prolonged exposure, while covering up with protective gear and waiting does not actively remove any residual pesticides. Lastly, only washing hands when irritation is felt disregards the preventive measures that should be taken immediately after handling potentially hazardous substances.
