Safety Data Sheet
Getting an SDS for Lead 2,4,6-trinitro-m-phen…
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 Lead 2,4,6-trinitro-m… 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
Lead 2,4,6-trinitro-m-phenylen… precautionary statements
CLP Annex VI assigns 12 precautionary statements to Lead 2,4,6-trinitro-m-phen…. 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
Lead 2,4,6-trinitro-m-phenylen… 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.

Lead 2,4,6-trinitro-m-phenylen… reactivity
LEAD STYPHNATE is a weak but highly sensitive explosive. An employee removing a beaker of lead styphnate from a laboratory oven caused a detonation when he bumped the beaker on the side of the oven [MCA Case History 957, 1966]. Three kilograms of lead styphnate exploded from an unknown cause. Wet material in two adjacent dry rooms did not detonate [Chem. Abs. 26:5210. 1932]. May react vigorously with reducing agents.
