Which guides are used for design parameters and reference for local exhaust ventilation?

• A. OSHA General Industry Handbook
• B. The local building code only
• C. Manufacturer Guide, ACGIH, Pre-Survey Form, DOEHRS
• D. EPA Regulation 40 CFR Part 60

Answer: (C)

Designing local exhaust ventilation relies on authoritative references that translate a process into a safe, effective capture system. Manufacturer guides provide the exact design parameters for the equipment itself—hood shapes, duct diameters, fan curves, filter types, and installation specifics—so you know how the system will actually perform in your setup. ACGIH offers established exposure guidance, translating contaminant properties and process details into target ventilation rates and capture velocities to keep worker exposures below recommended limits. A Pre-Survey Form helps gather all the necessary site-specific information before you design, ensuring the system is tailored to the particular processes, contaminants, and constraints. DOEHRS brings historical exposure data and risk context, helping you benchmark the design against prior measurements and health risk considerations in DOE facilities. Together, these sources give a practical, standards-aligned basis for both the parameters you design around and the references you cite during LEV design. Relying on other sources like a general OSHA handbook or local building codes alone misses the process-specific performance guidance and exposure targets, while EPA 40 CFR Part 60 focuses on emission standards for certain sources rather than providing a framework for local exhaust design parameters.
