Professional Standards & Competencies Flashcards

A NAFA-certified technician should obtain written authorization before performing work that exceeds the original scope because:

Answer: It protects both parties and ensures informed client consent

Written authorization for scope changes protects the technician legally and ensures the client understands and agrees to additional work.

The principle of 'duty of care' in air filtration service means a technician must:

Answer: Act with reasonable skill and caution to prevent harm to the client's system and occupants

Duty of care obligates the technician to perform services competently and safely, protecting building occupants and the client's equipment.

When a technician is uncertain whether a specific application requires HEPA or ULPA filtration, the best professional practice is to:

Answer: Consult NAFA resources, industry standards, or application engineering support

Consulting authoritative sources before recommending high-performance filtration ensures the correct product is specified for the hazard level.

Professionalism in post-service client communication includes:

Answer: Providing a summary of work performed, findings, and recommended next steps

A professional service summary reinforces trust, documents completed work, and sets clear expectations for future maintenance.

Which ethical obligation applies when a NAFA technician identifies a serious indoor air quality hazard unrelated to the current service call?

Answer: Notify the client of the hazard even if resolving it is outside the contracted scope

Professionals have an obligation to disclose known hazards to protect client health and safety, even when outside the contracted scope.

A technician who accepts gifts or incentives from a filter manufacturer in exchange for recommending their products is violating which principle?

Answer: Conflict of interest and professional impartiality

Accepting vendor incentives to influence product recommendations creates a conflict of interest that undermines the technician's independent professional judgment.

Field notes taken during a site survey should be treated as:

Answer: Official records that support work orders, proposals, and compliance documentation
