Which hazard pair is most associated with handling activated carbon?

Which hazard pair is most associated with handling activated carbon?

• A. Dust and fire
• B. An explosive atmosphere and respiratory problems
• C. Desiccation of other chemicals
• D. A slowing of processes

Answer: (A)

Activated carbon is a very fine, dry powder. Handling it creates respirable dust that can irritate the lungs and airways, making respiratory protection and good ventilation important. It’s also a combustible material—carbon dust can ignite or form explosive mixtures if dispersed in air and exposed to an ignition source. These twin risks of dust inhalation and fire/explosion potential are the hazards most associated with handling activated carbon, which is why this pairing fits best. The other options don’t align as closely with the usual hazards of this material: desiccating other chemicals isn’t a primary concern, and a general slowing of processes isn’t a typical hazard, while an explosive atmosphere could be related but is encompassed by the dust-and-fire risk already noted.
