IARC Cancer Evaluations in DOHSBase: Monographs 117-130 Added

Tracking which substances are classified as carcinogenic is one of the most important tasks in occupational hygiene. Multiple authoritative bodies publish cancer evaluations, and keeping up with all of them is a challenge. DOHSBase brings these sources together in one place, and the latest update adds IARC monographs volumes 117 through 130 as linked PDF references.

Why Carcinogen Tracking Matters

Under EU and national regulations, employers have specific obligations when workers are exposed to carcinogenic substances. These obligations include substitution requirements, exposure minimisation, registration and health surveillance. Identifying whether a substance is classified as carcinogenic — and by which authority — is therefore the starting point for any exposure assessment involving potential carcinogens.

Sources of Carcinogenic Classifications in DOHSBase

DOHSBase consolidates carcinogenic substance data from multiple authoritative sources:

• IARC evaluations — the International Agency for Research on Cancer classifies substances into Groups 1, 2A, 2B and 3 based on the strength of evidence for carcinogenicity in humans
• ECHA harmonised classifications (CLH) — legally binding EU classifications under CLP Annex VI, including Carc. 1A, Carc. 1B and Carc. 2
• ECHA notifications — self-classifications notified by manufacturers and importers
• ACGIH — the American Conference of Governmental Industrial Hygienists assigns H350 and H351 designations
• Dutch Health Council — provides advisory evaluations on carcinogenicity for Dutch regulatory purposes

By presenting these sources side by side, DOHSBase allows users to see the complete carcinogenicity picture for any given substance.

What Is New: IARC Monographs 117-130

The latest DOHSBase update adds references to IARC monographs volumes 117 through 130 as downloadable PDFs linked from the substance records. These monographs cover evaluations conducted in recent years and include both new substance evaluations and re-evaluations of previously assessed agents.

Each substance record in DOHSBase that has an IARC evaluation now links directly to the relevant monograph volume, making it straightforward to access the underlying scientific assessment.

How to Find IARC Data in DOHSBase Online

Follow these steps to look up IARC cancer evaluations for a substance in DOHSBase Online:

1. Search for the substance by name, CAS number or EC number
2. Open the substance record
3. Navigate to the classification section
4. Locate the IARC evaluation — the IARC group (1, 2A, 2B or 3) is displayed alongside other classifications
5. Click the monograph reference to access the PDF of the relevant IARC monograph volume

The classification section also shows harmonised CLP classifications, ECHA notifications and other carcinogenicity data sources, giving you a complete overview in one view.
