Which safety practices should you follow when mixing chemical solutions?

• A. Read labels, wear PPE, measure accurately, and avoid cross-contamination and spills
• B. Mix in a dirty area
• C. Skip PPE
• D. Use only water

Answer: (A)

When mixing chemical solutions, safety depends on following proper handling steps. Reading labels is essential because they tell you the chemical’s name, hazards, dilution instructions, required PPE, and first-aid actions, so you use it correctly and know what to expect. Wearing appropriate PPE protects your skin, eyes, and clothing from splashes, fumes, or spills. Measuring accurately ensures you achieve the correct concentration; too strong or too weak a solution can cause skin irritation, eye injury, ineffective results, or dangerous reactions. Preventing cross-contamination and spills keeps the workspace safe—using clean tools, labeling containers, and cleaning up promptly prevents unintended chemical reactions and exposure.

Mixing in a dirty area increases contamination and risk of accidental mix-ups. Skipping PPE leaves you unprotected against splashes or fumes. Using only water does not address proper handling, dilution, or safety precautions for the chemicals involved.
