Professional Standards & Competencies Flashcards

NAFA's code of ethics requires that a technician's recommendations be free from bias, which means the technician should:

Answer: Base recommendations solely on the client's application requirements and applicable standards

Ethical recommendations are driven exclusively by technical suitability for the client's application, not financial or personal bias.

A competent NAFA technician uses differential pressure gauges during service visits primarily to:

Answer: Assess filter loading status and determine whether replacement is warranted

Differential pressure across a filter indicates its dust-holding capacity utilization, which is the key trigger for replacement decisions.

Which situation most clearly requires a NAFA technician to escalate to a licensed mechanical engineer before proceeding?

Answer: A high-rise hospital AHU where proposed changes would modify supply air volume by more than 15%

Significant airflow modifications in critical environments exceed typical technician authority and require licensed engineering review for system integrity and code compliance.

The professional standard for handling a filter that is visibly saturated with biological contaminants (e.g., mold) includes all of the following EXCEPT:

Answer: Bagging the filter before removal

Bagging alone is not the initial standard — the filter should be contained before removal, but the primary professional requirement sequence involves notification, proper removal, documentation, and regulated disposal.

A client asks a NAFA-certified technician to certify that their cleanroom meets ISO 14644-1 classification requirements. The technician should:

Answer: Explain that room classification certification requires formal particle count testing by a qualified certification body

ISO 14644-1 room certification requires controlled particle count testing under specific protocols performed by a qualified testing and certification body, not a filter technician alone.

Maintaining an impartial stance when a client challenges a technician's recommended filter specification is best demonstrated by:

Answer: Presenting supporting data from applicable standards and offering to involve an independent third party if needed

Supporting recommendations with objective data and offering independent review upholds professional integrity while respecting the client's right to understand the rationale.

The primary reason NAFA promotes standardized competency frameworks for technicians is to:

Answer: Ensure consistent, high-quality service outcomes regardless of geographic location or employer

Standardized competency frameworks ensure that any NAFA-certified technician delivers a predictable, high-quality standard of service across diverse settings and employers.
