Cumulative Solvent Mixture & Multi-Chemical Calculator
Under OSHA regulations, when employees are exposed to two or more airborne contaminants, their combined toxicity is evaluated cumulatively. Even if every chemical is individually below its PEL, if the Cumulative Exposure Index exceeds 1.0, the facility is in non-compliance.
Configure Workplace Atmospheric Sample
Select work shift duration and add all airborne substances detected in the sampling area.
| Substance Name | CAS Number | Baseline PEL | Adjusted Shift PEL (Li) | Measured Air Conc (Ci) | Exposure Fraction (Ci/Li) | Action |

Recommended Multi-Substance Respiratory Protection
When workers handle solvent combinations, standard single-gas cartridges are often insufficient. OSHA 29 CFR 1910.134 mandates continuous protection against the most volatile component in the chemical mixture.
Protects against Organic Vapors, Chlorine, Hydrogen Chloride, Sulfur Dioxide, Ammonia, and Formaldehyde simultaneously.
