Mechanical control methods for ice and snow include which of the following?

• A. Snowplows
• B. De-icers
• C. Salt spreaders
• D. Sand

Answer: (A)

Mechanical control methods rely on physically removing snow and ice from surfaces using equipment that pushes, plows, or scoops material away. Snowplows exemplify this approach by pushing snow off runways, taxiways, and ramps, clearing paths for aircraft and ground vehicles. The other options work by altering the surface conditions rather than removing material: de-icers melt ice chemically, salt spreaders apply chemicals to promote melting, and sand provides traction on icy surfaces without removing the ice. So the action that represents mechanical removal among these is snowplowing.
