Why is it important for learners to wash their hands with soap and water after applying fertilizer?

Here is the answer for question 3:

Teacher Daniel's practice of reminding learners to wash their hands with soap and clean water after carrying out top dressing is important for the following reasons:

• Preventing chemical exposure: Inorganic fertilizers contain chemicals that can irritate the skin or be harmful if absorbed through cuts or ingested. Washing hands removes these residues.
• Maintaining hygiene: It prevents the accidental transfer of fertilizer chemicals to the mouth, eyes, or other parts of the body, reducing the risk of illness or discomfort.
