Which technique is NOT typically used for environmental monitoring during production operations? Response:

Question

Options

• AActive air sampling
• BUsing social media polls
• CNonviable particle counting
• DSwab sampling

• A
  9% (3)
• B
  83% (29)
• C
  6% (2)
• D
  3% (1)

Explanation

Using social media polls (B) is not a legitimate environmental monitoring technique because production environments - particularly in pharmaceutical, biotech, or cleanroom manufacturing - require scientifically validated, standardized methods to detect contamination and ensure product safety. Social media polls provide no objective, quantifiable data about air quality, particulates, or microbial presence.

The distractors are all real, established methods: Active air sampling (A) draws a measured volume of air through a collection medium to capture viable microorganisms; Nonviable particle counting (C) uses optical sensors to measure airborne particles by size, ensuring cleanroom classification compliance; and Swab sampling (D) recovers microorganisms from surfaces to detect potential product contamination.

Memory tip: Think "SANS" - Swab, Air sampling, Nonviable particle counting, and Surface monitoring are the four pillars of environmental monitoring. Anything outside objective, instrument- or culture-based data collection doesn't belong in a regulated production environment.
