01 · Identification
What Erionite is
Erionite is a hexagonal, cage-like structure composed of a framework of linked (Si,Al)O4 tetrahedra. Its molecular formula is AlCaH60KNaO36Si2+3 and its molecular weight is 821.77 g/mol.
Under the GHS it carries the signal word Danger. It is classed as carcinogens.

03 · GHS classification
Erionite hazard classification
Harmonised classification under CLP Annex VI. This is the legally binding classification in the EU; other jurisdictions may differ.
Erionite pictograms and signal word
Erionite hazard class and category
| Hazard class | Category | From code | Pictogram |
|---|---|---|---|
| Carcinogenicity GHS chapter 3.6 | Category 1A or 1B | H350 | GHS08 |
Where two values are shown with “or”, the hazard statement is shared by more than one category or by more than one class, and the code alone does not say which. H272, for example, belongs to oxidising liquids and to oxidising solids — the physical state decides. The binding answer for a specific entry is in the CLP Annex VI table itself.
Erionite hazard statements (H-codes)
| Code | Hazard statement |
|---|---|
| H350 | May cause cancer <state route of exposure if it is conclusively proven that no other routes of exposure cause the hazard>. |
This page lists only the codes assigned to Erionite. The full reference lives on the hazard statements hub, the precautionary statements hub and the GHS pictograms hub.
Safety Data Sheet
Getting an SDS for Erionite
A Safety Data Sheet is written for a product, not for a substance: the supplier of the grade you actually buy issues it, so two suppliers of Erionite issue two different sheets. That is why there is no single authoritative SDS for a substance to download — what there is, is the job of collecting the sheets for the products you hold and keeping them current as suppliers revise them.
04 · Precautionary statements
Erionite precautionary statements
CLP Annex VI assigns 4 precautionary statements to Erionite. They are grouped the way a label groups them: what to do before handling, what to do when something has already happened, how to store it and how to dispose of it.
Prevention
What to do before and during handling so the hazard never happens.
Response
What to do once exposure, spillage or fire has already happened.

05 · Names in the regulation
Erionite name in 23 EU languages
CLP Annex VI Part 3 is published in every language edition of the regulation, and the identification column is written out in each of them. Nothing below is translated by us: each line is the name as that edition prints it. Under Art. 18(2) the substance name from Annex VI is a lawful product identifier, so this is the wording to put on a label going to that market — and where the cell lists several designations, any one of them qualifies.

All 23 language editions of Annex VI carry this entry. Irish is the twenty-fourth official EU language and has no line here for a different reason: no consolidated CLP text has ever been published in Irish, so there is no Irish edition of Annex VI to quote a name from.

Erionite health hazards and exposure limits
Erionite hazard summary
Natural zeolites include analcite, chabazite, heulandite, natrolite, stilbite, and thomosonite. [Hawley] Erionite is one of about 40 natural zeolites, which are hydrated aluminosilicates of the alkaline and alkaline-earth metals. Studies of Turkish villages with high dust exposures to erionite found increased incidence of mesotheliomas, and erionite fibers were found in lung tissue samples. Erionite causes mesothelioma in experimental mice and rats. [NTP]

Erionite carcinogenicity classification
ERIONITE (Group 1). A. Evidence for carcinogenicity to humans (sufficient). B. Evidence for carcinogenicity to animals (sufficient).
Source: Hazardous Substances Data Bank (HSDB)
Erionite is known to be a human carcinogen based on sufficient evidence of carcinogenicity in humans.
Source: Hazardous Substances Data Bank (HSDB)
An IARC group and a CLP classification answer different questions. IARC judges whether the evidence for cancer in humans is strong enough; CLP Annex VI is the legally binding EU classification. A substance can carry one and not the other.

Erionite properties
Every value is shown with the conditions it was measured under and the source it came from. Where sources disagree, all values are listed rather than one being picked — the difference is usually a different form of the substance, not an error.
