Among the eight precautions for removing corrosion by chemical means, which item is NOT listed?

• A. Consult the SDS to ensure that adequate PPE is used during the entire process.
• B. Use in a well ventilated area.
• C. Do not allow solutions to contact steel or copper surfaces as this can cause severe corrosion or hydrogen embrittlement affecting the metals strength.
• D. Wear gloves made of cotton.

Answer: (D)

The key idea is to protect workers and preserve the metal when removing corrosion with chemicals. Safety Data Sheets guide you to the right PPE, ensuring you have the right protection for the chemicals involved. A well-ventilated area is essential to minimize inhaling fumes and to keep the working environment safer. It’s also crucial to avoid letting cleaning solutions contact steel or copper surfaces because those reactions can cause severe corrosion or hydrogen embrittlement, which weakens the metal’s strength. Gloves made of cotton don’t provide adequate chemical protection—they absorb liquids, can become contaminated, and offer little resistance to the corrosive agents used in these processes. Instead, chemical‑resistant gloves (like nitrile or neoprene) are what's recommended, along with other PPE specified by the SDS. That’s why cotton gloves aren’t listed as a precaution for this task.
