Regulatory Compliance & Legal Framework Flashcards

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

Answer: Particle size capture efficiency across three particle size ranges

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).

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

Answer: EPA

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

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?

Answer: Mandatory code-adopted standard

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

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

Answer: It sets emission standards for hazardous air pollutants from stationary sources

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

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

Answer: 99.97% efficiency at 0.3 µm

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.

Which OSHA standard most directly governs worker exposure to airborne contaminants and therefore influences industrial filtration system design?

Answer: 29 CFR 1910.1000 (Air Contaminants / PELs)

29 CFR 1910.1000 establishes Permissible Exposure Limits (PELs) for hundreds of airborne substances, directly driving ventilation and filtration requirements.

A technician discovers that a client's nuclear facility air filtration system must comply with 10 CFR Part 50. Which regulatory body issues this standard?

Answer: NRC

10 CFR Part 50 is issued by the Nuclear Regulatory Commission (NRC) and governs domestic licensing of production and utilization facilities including nuclear plants.
