Covers 26 jurisdictions across the United States and Canada. --- What This Does -------------- [](#what-this-does) Given a cleaning product's VOC content, a room's geometry, and ventilation parameters, this tool calculates: - **VOC concentration** (mg/m³) at steady state during a cleaning cycle - **OSHA PEL comparison** — what percentage of the Permissible Exposure Limit the concentration represents - **Time to safe reentry** — how long until VOC concentration drops below 10% of PEL - **Annual VOC load** — total VOC released per year at the given cleaning frequency - **Multi-jurisdiction compliance** — whether the product meets VOC limits in each of 26 jurisdictions --- Datasets -------- [](#datasets) Two CSV datasets are included in `datasets/`: ### Dataset A: VOC Regulatory Limits by Jurisdiction (650 rows) [](#dataset-a-voc-regulatory-limits-by-jurisdiction-650-rows) VOC limits (g/L) for 25 cleaning product categories across 26 jurisdictions: - US Federal (EPA 40 CFR Part 59 Subpart C) - California (CARB Consumer Products Regulations) - 12 OTC states (CT, DE, ME, MD, MA, NH, NJ, NY, PA, RI, VA, DC) - 8 states with independent regulations (MI, CO, IL, IN, IA, OH, UT, WA) - Canada Federal (SOR/2021-268) - Ontario, British Columbia, Quebec Each row includes the product category, numeric VOC limit, regulation name, effective date, and healthcare-specific context notes. ### Dataset B: Healthcare Cleaning Product VOC Compliance Matrix (5,000 rows) [](#dataset-b-healthcare-cleaning-product-voc-compliance-matrix-5000-rows) Synthetic product data modeled on real institutional cleaning product categories: - VOC content (g/L concentrate and effective diluted) - Certifications (Green Seal GS-37, UL ECOLOGO, EPA Safer Choice, UL GREENGUARD Gold, LEED v4) - Per-jurisdiction compliance flags (compliant/non-compliant in each of 26 jurisdictions) - Healthcare approval status, IPAC compatibility rating - Pricing (CAD/litre), dilution ratios, coverage rates - Recommended healthcare facility types --- Calculation Model ----------------- [](#calculation-model) ``` effective_voc = product_voc_g_per_L × dilution_ratio product_applied_L = room_sqft / coverage_sqft_per_L total_voc_mg = effective_voc × product_applied_L × 1000 # Single-zone mass balance with ventilation emission_rate = total_voc_mg / cleaning_duration_hr ventilation_rate = air_changes_per_hour × room_volume_m3 steady_state = emission_rate / ventilation_rate osha_pel_percent = (steady_state / 300) × 100 ``` ASHRAE 62.1-2022 minimum ventilation rates for healthcare spaces are built in as reference values: Space TypeMinimum ACHPatient room6ICU12Operating room20Exam room6Corridor4Laboratory12Dietary kitchen10--- Engines ------- [](#engines) The calculation is implemented in seven languages.
