Data Sources

The chemical hazard information contained in ChemHAT comes from the Chemical and Material Library (CML) created by the Healthy Building Network for its Pharos database of chemicals and materials in building products. The CML is a first-of-its-kind database that checks a library of over 180,000 chemicals and materials against 77 authoritative chemical hazard lists (see description below) and 50 restricted substances lists developed by state, national, and international governmental agencies, retailers, brands, manufacturers, and other reputable, science-based non-governmental organizations.

When you look up a chemical in ChemHAT, you’ll find icons indicating the health effects the chemical can cause, as well as information about how you’re likely to be exposed to the chemical (e.g., by breathing it, or having it touch your skin or eyes.) If you’re interested in knowing where we got the information about that particular health effect, click on the “How We Know” link to the right of the hazard icon you’re interested in. Chemicals that have health effects icons in ChemHAT are verified by scientists as having specific effects on health or the environment (see below for an explanation of Authoritative Lists.)

Hazard Information and Authoritative Lists

There are two main types of lists associated with chemical hazards in the information we draw from Pharos: chemical hazard lists and restricted substance lists (RSLs). Here’s how Pharos describes their data sources:

Pharos provides resources to assess human and environmental health hazards of chemicals plus tools to collaborate to find safer alternatives. The goal of this effort is to reduce the use of hazardous chemicals and improve the inherent safety of materials and products. Pharos aggregates hazard lists to make associations between chemicals and 26 specific human and environmental health endpoints, assigning a high, moderate or low concern for each endpoint whenever possible. The Pharos team constantly monitors data sources to keep up to date.

Many organizations rely on these same authoritative lists to evaluate chemical hazards when looking for safer chemicals, materials and products, including companies, institutional purchasers, and governments. ChemHAT now makes this information available for workers.
