What does vacuum blasting utilize?

  1. A mixture of air and water

  2. A vacuum system attached to the blast head

  3. Only solid materials for blasting

  4. Compressed air systems

The correct answer is: A vacuum system attached to the blast head

Vacuum blasting utilizes a vacuum system attached to the blast head, which effectively combines the abrasive blasting process with a method for debris control. This system is designed to contain and remove the particles released during the blasting operation. By maintaining a vacuum at the blast head, it ensures that dust, debris, and other contaminants are captured immediately, preventing them from being released into the surrounding environment. This not only improves visibility for the operator but also enhances workplace safety and compliance with environmental regulations. The efficiency of the vacuum system in collecting the abrasive material can help minimize cleanup time and reduce the hazards associated with airborne debris.
