A facility proposes an electrostatic particle collector to reduce particles leaving a controlled industrial process. Supplied pilot evidence: In one test the particle reading fell from 200 to 40 instrument units, but the test did not measure gases or long-term plate fouling. Collected material still requires disposal, equipment uses energy, and some designs can generate unwanted by-products. Evaluate the proposal for workers, nearby residents and waste handlers. Explain the relevant physics, distinguish evidence from an assumption, discuss a benefit and a cost or ethical issue, and make a conditional recommendation with one further evidence requirement. Treat the supplied figures as a fictional classroom case, not as current product or safety guidance.
Task interpretation
What a complete response should do
Organise the response into a logical argument, linking the physics principle to the evidence and conclusion.
Make assumptions explicit, connect several ideas, and test whether the final result is physically reasonable.
