Which non-governmental organization publishes consensus standards for allowable concentrations of chemicals and physical agents?

Which non-governmental organization publishes consensus standards for allowable concentrations of chemicals and physical agents?

• A. Acgih
• B. Ansi
• C. Nrc
• D. Epa

Answer: (B)

The key idea is who publishes consensus exposure guidance used by professionals to judge safe levels for chemicals and physical agents. The American Conference of Governmental Industrial Hygienists is a private, non-governmental organization that issues Threshold Limit Values (TLVs) and Biological Exposure Indices (BEIs), which define recommended allowable concentrations. These TLVs are widely used as exposure guidelines, though they’re not binding laws—that role belongs to regulatory agencies. ANSI also publishes standards, but not specifically the exposure limits for chemicals and physical agents. NRC and EPA are government agencies, not non-governmental organizations. So the organization that fits the description is ACGIH, known for its consensus exposure guidelines.
