RMS Quality & Compliance Flashcards

Under EPA guidelines, what is the maximum acceptable radon level in a home before mitigation is strongly recommended?

Answer: 4 pCi/L

The EPA recommends mitigation when radon levels are at or above 4 pCi/L.

A post-mitigation test result shows 3.8 pCi/L. What is the most appropriate next step?

Answer: Discuss system optimization options with the homeowner

At 3.8 pCi/L the level is just below the EPA action level but still above the 2 pCi/L goal, so optimization should be discussed.

Which organization administers the most widely recognized RMS certification program in the United States?

Answer: AARST-NRPP

AARST-NRPP (National Radon Proficiency Program) is the primary certifying body for radon mitigators in the U.S.

How often must a certified RMS renew their NRPP certification?

Answer: Every 3 years

NRPP requires certified professionals to renew every 3 years with continuing education credits.

Which document must an RMS provide to a homeowner upon system installation to meet EPA standards of practice?

Answer: A written system description and post-mitigation test protocol

EPA standards require a written system description and guidance on post-mitigation testing to be provided to the homeowner.

What is the primary purpose of the diagnostic assessment performed before designing a radon mitigation system?

Answer: To determine the appropriate sub-slab communication and entry points

Diagnostic testing assesses sub-slab communication and soil conditions to guide effective system design.

A state requires radon contractors to carry general liability insurance with a minimum of $300,000 per occurrence. An RMS carries only $250,000. What is their compliance status?

Answer: Non-compliant with state requirements

State licensing requirements are mandatory and take precedence; carrying less than the required minimum renders the contractor non-compliant.
