In terms IAQ, how useful is an MSDS?

• A. May be of limited help in identifying some products that could pose IAQ concerns
• B. Very comprehensive for all IAQ concerns
• C. Not relevant to IAQ
• D. Provides exact hazard details for every product

Answer: (A)

MSDSs (Safety Data Sheets) provide hazard information about products and can help you spot substances that might affect indoor air quality, such as solvents or VOCs, and they offer guidance on ventilation, handling, and personal protection. That makes them useful as a starting point for identifying potential IAQ concerns. But they aren’t a complete IAQ tool: they don’t give emission rates, real-world indoor concentrations, or comprehensive exposure data for every product, and formulations can change without immediate updates. They may also present occupational exposure limits rather than indoor-air-specific guidance. So, their usefulness is limited to flagging some products that could pose IAQ issues, rather than delivering full IAQ assessments.
