1,3,5-Trinitrobenzene hazard class and category
| Hazard class | Category | From code | Pictogram |
|---|---|---|---|
| Explosives GHS chapter 2.1 | Category 1.1 | H201 | GHS01 |
| Acute toxicity - oral GHS chapter 3.1 | Category 1 or 2 | H300 | GHS06 |

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 1,3,5-Trinitrobenzene
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 1,3,5-Trinitrobenzene 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
1,3,5-Trinitrobenzene precautionary statements
CLP Annex VI assigns 15 precautionary statements to 1,3,5-Trinitrobenzene. 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.
Disposal
What has to happen to the contents and the empty container.

05 · Names in the regulation
1,3,5-Trinitrobenzene 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.

1,3,5-Trinitrobenzene fire and explosion behaviour
These are descriptions rather than measured values, so they are kept out of the table above and quoted here with the source that reported them.
Fire and explosion
A severe explosion hazard when shocked or exposed to heat. Trinitrobenzene is considered a powerful high explosive and has more shattering power than TNT. ... It is less sensitive to impact than TNT ... . The complex with potassium trimethyl stannate explodes at room temperature. Forms heat-sensitive explosive complexes with alkyl or aryl metallates (e.g., lithium or potassium salts of trimethyl-, triethyl-, or triphenyl-germanate, -silanate, or -stannate).

1,3,5-Trinitrobenzene storage conditions
Treat as an explosive. ... Store separately from all other flammable materials. Prior to working with this chemical you should be trained on its proper handling and storage. Store in tightly closed containers in a cool, well-ventilated area away from heat, explosives, oxidizable materials. Sources of ignition, such as smoking and open flames, are prohibited where this chemical is used, handled, or stored in a manner that could create a potential fire or explosion hazard. Use only nonsparking tools and equipment, especially when opening and closing containers of this chemical.

1,3,5-Trinitrobenzene reactivity
Aromatic nitro compounds, such as TRINITROBENZENE, range from slight to strong oxidizing agents. If mixed with reducing agents, including hydrides, sulfides and nitrides, they may begin a vigorous reaction that culminates in a detonation. The aromatic nitro compounds may explode in the presence of a base such as sodium hydroxide or potassium hydroxide even in the presence of water or organic solvents. The explosive tendencies of aromatic nitro compounds are increased by the presence of multiple nitro groups.
