NCT Regulatory Compliance & Legal Framework 2

Question 1

Under ASHRAE 52.2, what does the Minimum Efficiency Reporting Value (MERV) rating system primarily measure?

Accepted Answer

Particle size capture efficiency across three particle size ranges

Answer

MERV rates filters by their ability to capture particles in three size ranges: E1 (0.3–1.0 µm), E2 (1.0–3.0 µm), and E3 (3.0–10.0 µm).

Question 2

Which federal agency enforces the National Emission Standards for Hazardous Air Pollutants (NESHAP) that may affect industrial air filtration systems?

Accepted Answer

EPA

Answer

The Environmental Protection Agency (EPA) is responsible for enforcing NESHAP regulations under the Clean Air Act.

Question 3

A facility manager installs MERV 8 filters in a hospital critical care area that requires MERV 14 per ASHRAE 170. This is a violation of which type of standard?

Accepted Answer

Mandatory code-adopted standard

Answer

ASHRAE 170 is adopted by many state and local codes as mandatory for healthcare facilities, making non-compliance a code violation.

Question 4

What is the primary purpose of the EPA's Clean Air Act Section 112 as it relates to air filtration?

Accepted Answer

It sets emission standards for hazardous air pollutants from stationary sources

Answer

Section 112 of the Clean Air Act establishes NESHAP, controlling hazardous air pollutant emissions from stationary industrial sources.

Question 5

When a filter manufacturer claims a product is 'HEPA,' what minimum efficiency must it demonstrate per U.S. DOE standards?

Accepted Answer

99.97% efficiency at 0.3 µm

Answer

DOE defines a HEPA filter as one that captures at least 99.97% of particles at the most penetrating particle size of 0.3 µm.
