Storage conditions
DOT Class A explosive. Initiating explosive. Keep away from fire, heat, flame, spark, static, friction, percussion. Do not store with flammable liquids, solids, gases, oxidizers, acids, corrosive liquids, non-flammable compressed gases. Storage and distribution of explosives is regulated by the U.S. Department of the Treasury, Bureau of Alcohol, Tobacco, and Firearms (BAFT). Procedural requirements are described in 25 CFR 55, "Commerce in Explosives"

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.

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.
