FAQ CATEGORY: Indoor Air Quality Compliance

Air quality compliance in industrial facilities typically involves multiple frameworks that serve different functions. 

• OSHA establishes legally enforceable permissible exposure limits (PELs) for workplace contaminants; these are the regulatory floor. 
• ACGIH threshold limit values (TLVs) and NIOSH recommended exposure limits (RELs) are not enforceable regulations but are widely used as benchmarks because they reflect current health-based science and are generally more protective than OSHA PELs. 
• EPA standards govern environmental emissions and ambient air quality rather than worker exposure directly. 

The specific combination of standards that applies to your facility depends on your processes, materials and location.

The most reliable way to determine compliance is through a formal air quality compliance assessment or audit. This process measures current conditions, compares them to applicable standards and identifies any gaps that need to be addressed.

Noncompliance with industrial air quality regulations can lead to fines, enforcement actions, operational disruptions and increased liability, especially if employee health or environmental impact is affected. It can also damage reputation and create long-term operational challenges.

No, industrial air quality compliance is ongoing. As regulations evolve and facility conditions change, regular monitoring and adjustments are necessary to maintain alignment and reduce risk over time.
