Which material is included in Houghto-safe composition?

• A. Water
• B. 50-50 water and water-soluble polymers and red dye
• C. Ethylene Glycol
• D. Glycerin

Answer: (B)

The principle being tested is understanding what Houghto-Safe is made of and why those components are chosen. Houghto-Safe is a leak-detection and safety solution used in maintenance, so its signature mix includes water as the solvent, a water-soluble polymer to give a light viscosity that helps the liquid cling to surfaces, and a red dye to make any leaks or damp areas clearly visible.

Choosing a 50-50 blend of water and water-soluble polymers with red dye provides just the right balance: enough viscosity to stay where applied and still flow to reveal leaks, plus a bright color to clearly indicate where fluid is present. Pure water wouldn’t show leaks or stay in place well, and substances like Ethylene Glycol or Glycerin introduce different properties (such as antifreeze characteristics or higher viscosity) that aren’t part of the intended Houghto-Safe formulation.
