What safety precaution should insulators take when mixing hydraulic setting cement?

• A. Wear gloves
• B. Wear safety goggles
• C. Use a respirator
• D. No PPE

Answer: (A)

When hydraulic cement is mixed, the wet slurry is highly alkaline and can burn or irritate the skin on contact. Wearing gloves provides a direct barrier between your hands and the cement, making it the most effective single precaution to prevent chemical burns during mixing. Safety goggles protect your eyes from splashes, and a respirator would be useful if there’s dust or fumes, but the primary risk here is skin contact, so gloves are the best choice. No PPE is not acceptable, since exposure can cause harm.
