Monitoring air quality during the application of 2-part spray foam products presents a unique challenge, especially when isocyanates are involved. Unfortunately, particle counters and VOC monitors cannot reliably detect isocyanates, making laboratory analysis the only viable solution for accurate measurement.
Isocyanates, used in spray foam insulation and other industrial applications, are hazardous to health and require precise monitoring to ensure workplace safety. Misinterpreting air quality data or relying on inappropriate instruments can lead to significant risks for workers. At LCS Laboratory Inc., we specialize in isocyanate testing and provide detailed, lab-based analysis tailored to industrial hygienists and safety professionals.
Why Common Air Quality Instruments Fall Short
- Particle Counters:
Particle counters measure airborne particulate matter but fail to detect isocyanates in their volatile gaseous form. Furthermore, the mist from the foam application contains a relatively small fraction of isocyanate thus, the particle counting of nonvolatile isocyanates may lead to overestimation, giving a false sense of the actual exposure levels. - VOC Monitors:
VOC monitors detect a wide range of volatile organic compounds (VOCs), which are abundant on construction sites. However, they cannot differentiate isocyanates from other VOCs. Additionally, isocyanates are regulated at extremely low thresholds (e.g., 2 ppb), far below the detection capability of most VOC devices, which are often set to measure in the 50–500 ppb range. - Direct-Reading Instruments:
Historically, instruments capable of detecting isocyanates existed but became obsolete as regulatory limits tightened. Current thresholds require extremely sensitive methods, which are not met by any commercially available direct-reading device.
The Benefits of Using a Canadian Testing Laboratory
As a Canadian laboratory with ISO 17025 accreditation, LCS Laboratory Inc. provides expert analytical services to meet the stringent health and safety standards of Canadian industries. Collaborating with us ensures:
- Compliance with Canadian Regulations: We use advanced methods to detect isocyanates at regulatory levels, protecting your workforce and keeping you compliant.
- Quick Domestic Access: Avoid delays and complexities associated with cross-border shipping or international labs.
- Expert Consultation: Our team provides clear guidance on sample collection, testing, and interpreting results.
Conclusion: Lab Testing Remains the Gold Standard
Currently, laboratory testing is the only reliable method for measuring isocyanates in workplace environments. Instruments such as particle counters or VOC monitors cannot provide the accuracy or specificity needed for this critical task.
