The correct answer to this question is:
C) Both A and B
Explanation:
1. Technician A is correct: Compressed air is often recommended for cleaning dust from a work area because it effectively removes dust without the need for additional cleaning agents. It is commonly used in industrial settings to clean machinery, equipment, and workspaces.
2. Technician B is also correct: The solvent used in a parts washer becomes a generated waste because it gets contaminated with dirt, grease, and other residues from the parts being cleaned. This contaminated solvent cannot be reused indefinitely and needs to be disposed of properly as hazardous waste.
Therefore, both Technician A and Technician B are correct in their statements.
