ECETOC is the European Centre for Ecotoxicology and Toxicology of Chemicals. It's Targeted Risk Assessment (TRA) tool calculates the risk of exposure from chemicals to workers, consumers and the environment. It's a preferred approach for evaluating consumer and worker health risks in the European Union.

Let's use Hydrogen Sulfide as example. Search for it by typing in the search box.
Pick the product from the list.

This is the profile page of Hydrogen Sulfide. Notice its hazards and recommended precautions

Now scroll down to the RCR table© and its Risk Characterization Ratios.

Hazard is a function of a chemical’s inherent properties. Risk, however, is a function of exposure. The combined view of a chemical's inherent hazard and its quantity in a specific exposure scenario, is a useful representation of risk.

The red values (>1) indicate unacceptable risk, whereas the green values (<1) represent tolerable risk for each of the given exposure scenarios.

Scenario parameters can be set to a specify usage context, otherwise defaults are used.

We currently support ECETOC TRA 3.1. Other calculation methods are available.
