Tri-Sodium Phosphate is described as what in the context of lead dust cleanup?

• A. A special ingredient in some detergents that bonds with lead dust to remove it from surfaces.
• B. A solvent that dissolves lead-based paint.
• C. A drying agent for painted surfaces.
• D. A disinfectant for surfaces.

Answer: (A)

In lead dust cleanup, the goal is to physically remove lead-bearing dust from surfaces, not to dissolve paint or kill germs. Tri-Sodium Phosphate is described as a special ingredient in some detergents because it helps bind or suspend lead dust so it can be washed away more effectively. It acts as a strong cleaning agent, creating an alkaline environment that loosens dirt and dust and allows them to be rinsed off with water. This makes it more about facilitating removal of contaminants than about dissolving paint, drying surfaces, or acting as a disinfectant.
