Both of the technicians A and B are right in their statements.
Why are they both correct?
Compressed air is recommended for cleaning dust from a work area because its helps to effectively blow away dust and debris from surfaces, machinery and other work areas without the need for additional chemicals or solvents.
The solvent currently in use in a parts washer is indeed a generated waste. They are used for cleaning in industrial processes and can become contaminated with oils, grease and other substances. This makes them hazardous waste materials that must be properly disposed of according to environmental regulations.
In summary, both technicians are right in their statements.
