Cadmium cyanide hazard class and category

GHS hazard classes Cadmium cyanide falls into
Hazard class Category From code Pictogram
Acute toxicity - oral GHS chapter 3.1 Category 1 or 2 H300 GHS06
Acute toxicity - dermal GHS chapter 3.1 Category 1 or 2 H310 GHS06
Acute toxicity - inhalation GHS chapter 3.1 Category 1 or 2 H330 GHS06
Carcinogenicity GHS chapter 3.6 Category 2 H351 GHS08

Hazardous to the aquatic environment - acute GHS chapter 4.1 Category 1 H400 GHS09
Hazardous to the aquatic environment - chronic GHS chapter 4.1 Category 1 H410 GHS09

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.

Safety Data Sheet

Getting an SDS for Cadmium cyanide

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 Cadmium cyanide 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

Cadmium cyanide precautionary statements

CLP Annex VI assigns 17 precautionary statements to Cadmium cyanide. 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.

05 · Names in the regulation

Cadmium cyanide 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.

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.

Cadmium cyanide occupational exposure limits

US occupational exposure limits reported for Cadmium cyanide. PEL is enforceable (OSHA), REL is a recommendation (NIOSH), IDLH is the concentration at which escape becomes impossible without injury.
Limit Value Source
PEL 0.005 [mg/m3], as Cd, see 29 CFR 1910.1027, (5 mg/m3, as CN) Haz-Map, Information on Hazardous Chemicals and Occupational Diseases
IDLH 9.0 [mg/m3], as Cd (25 mg/m3, as CN) Haz-Map, Information on Hazardous Chemicals and Occupational Diseases

These are United States values. The European Union sets its own indicative and binding limits, and the figure that applies at a given workplace is the one in the local regulation — not the one shown here.

08 · Questions

Cadmium cyanide — frequently asked questions

What is the CAS number of Cadmium cyanide?

The CAS number of Cadmium cyanide is 542-83-6. Its EC number is 208-829-1.

The molecular formula of Cadmium cyanide is C2CdN2 and its molecular weight is 164.45 g/mol.

What does a Cadmium cyanide label have to show?

Under CLP Annex VI the label for Cadmium cyanide carries the pictograms Skull and crossbones, Health hazard and Environment and the signal word is Danger.

Is Cadmium cyanide flammable?

CLP Annex VI assigns Cadmium cyanide no flammability hazard class. That is not a statement that it cannot burn: the harmonised list only records the hazards that were assessed for it.

Is Cadmium cyanide a carcinogen?

CLP Annex VI assigns Cadmium cyanide H351 — suspected of causing cancer. That is category 2: the evidence points that way but is not conclusive.

What is the exposure limit for Cadmium cyanide?

The US occupational exposure limit reported for Cadmium cyanide is 0.005 [mg/m3], as Cd, see 29 CFR 1910.1027, (5 mg/m3, as CN) (Haz-Map, Information on Hazardous Chemicals and Occupational Diseases). Limits differ by country: the EU sets its own indicative and binding values, and the figure that applies at a given workplace is the one in the local regulation.
