Key Summary: DOHSBase Compare is the risk assessment and prioritisation layer within DOHSBase Online. Rather than assessing substances one by one, Compare ranks them with a reproducible Risk Assessment Score (RAS), built from a toxicity score (TOX) and an exposure index (TIX). In a mixed substance inventory you can see at a glance which substances deserve the most attention. The articles below explain the underlying methodology, how measurements are tested against exposure limits under EN 689, and the scientific validation the approach rests on. The methodology supports a risk-first approach: first determine which substances pose the greatest risk, then measure and control where it matters.
This cluster goes deeper into the methodology behind the DOHSBase Compare module. The product page describes what the module does; the articles below explain how and why.
Articles in this cluster
- TOX, TIX and RAS score: the methodology — how toxicity and exposure combine into a single risk score.
- EN 689 compliance assessment — testing TWA measurements against OELs with UTL statistics.
- DOHSBase methodology: validation and recognition — the scientific basis and regulatory recognition.
- Risk-first vs disease-first — where OELs, DNELs and kick-off values fit in proactive screening.
Related: kick-off values provide an exposure benchmark for substances without a formal OEL, a common case in risk prioritisation.
In DOHSBase Online, Compare calculates the RAS for every substance in your list, based on reviewed exposure limits, kick-off values and H-statements.
