HANDLING & STORAGE
The toxicological properties of Heavy Aromatics are similar to Solvent CIX and
Xylenes . It is not classified as higly inflammable because of higher flash point
and therefore does not come under Explosive Storage Regulations. However , all
necessary precautions should be taken against fire hazard during storage and
use.
