Safety Data Sheet
Getting an SDS for Thiocarbonyl chloride
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 Thiocarbonyl chloride 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
Thiocarbonyl chloride precautionary statements
CLP Annex VI assigns 17 precautionary statements to Thiocarbonyl chloride. 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
Thiocarbonyl chloride 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.

09 · Handling and storage
Thiocarbonyl chloride storage and handling
Thiocarbonyl chloride incompatible materials
Reactivity with water: Evolves hydrogen chloride, carbon disulfide, & carbon dioxide. Reaction is slow unless water is hot.
Source: Hazardous Substances Data Bank (HSDB)
Thiocarbonyl chloride reactivity
THIOPHOSGENE is incompatible with acids, diazo and azo compounds, halocarbons, isocyanates, aldehydes, alkali metals, nitrides, hydrides, and other strong reducing agents. Reactions with these materials generate heat and in many cases hydrogen gas. Liberates hydrogen sulfide upon reaction with acids.

What does a Thiocarbonyl chloride label have to show?
Under CLP Annex VI the label for Thiocarbonyl chloride carries the pictogram Skull and crossbones and the signal word is Danger.
Is Thiocarbonyl chloride flammable?
CLP Annex VI assigns Thiocarbonyl chloride 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 Thiocarbonyl chloride a carcinogen?
CLP Annex VI records no harmonised carcinogenicity classification for Thiocarbonyl chloride. Annex VI is a list of agreed classifications, not a list of substances found safe, so this is an absence of a classification rather than a clean bill of health.
