Activated Carbon - Low Density Skeleton
Substance description: A porous, amorphous, high surface area adsorbent material composed of largely elemental carbon, with a low skeletal density.
(Activated carbon with a low density skeleton is produced by activation with chemical activation agents such as phosphoric acid, of various raw materials such as wood and synthetic sources.)

Classification: Either one of the following classifications may apply:
- not classified
- classified as Self-heating (corresponding to transport class 4.2)
The producer/importer shall determine for his products which of these two possibilities apply, by testing the material and considering the packaging size.
CLP Classification:
Selfheating, Category 2
Signal word:
Warning
Hazard statement:
H252: Self heating in large quantities, may catch fire.
Precautionary statements:
P235+ 410: Keep cool. Protect from sunlight.
P280: Wear protective gloves/protective clothing/ eye protection/ face protection.
P413: Store bulk masses greater than 50.000 kg / 110.000 lbs at temperatures not exceeding 50 °C.
