Authoritative Frameworks for Chemical Hazard Screening
The Chemical Data Commons by Healthy Building Network unifies authoritative chemical hazard assessments into a single open platform. Built on cross-referenced chemical lists, it translates complex hazard traits into transparent benchmarks, enabling specifiers and manufacturers to identify toxic substances across building products and evaluate safer chemical alternatives.
Evaluation Standards and Hazard Benchmarks Comparison
| Benchmark / Standard | Governing Body / Source | Primary Scope | Screening Threshold |
|---|---|---|---|
| GreenScreen for Safer Chemicals | Clean Production Action | Comprehensive hazard profiling (Benchmark 1-4) | 100 ppm |
| Living Building Challenge Red List | International Living Future Institute | Banned high-priority toxic chemicals | 100 ppm or 1000 ppm depending on chemical |
| Pharos Hazard Framework | Healthy Building Network | Aggregated hazard scoring across 70 authoritative lists | 100 ppm |
| Cradle to Cradle Certified (C2C) | Cradle to Cradle Products Innovation Institute | Material health and restricted substances list | 100 ppm for basic evaluation |
Chemical Hazard Assessment and Evaluation Workflow
- Identify Chemical Identifiers: Verify CAS numbers, EC numbers, and synonyms against registry standards.
- Map Against Authoritative Lists: Screen substances against 70 global regulatory and restricted lists.
- Determine Endpoint Hazard Scores: Evaluate endpoints including carcinogenicity, reproductive toxicity, and persistence.
- Assign Overall Benchmark Tier: Calculate composite hazard tier to guide informed substitution and safer material specification.
Complex Assessment Boundaries and Data Limitations
Evaluation results must account for data gaps where substances lack authoritative testing records. Incomplete hazard data does not equate to proven safety, requiring conservative hazard tiering and precautionary substitution rules.
