PACKAGING

On packaging containers of industrial methanol products, firm marks should be painted to maintain clean and dry containers that are sealed.

STORAGE & TRANSPORT

Methanol should be stored in a dry, cool and ventilate location away from sunlight, heat and fire.

SAFETY

Methanol is a colorless inflammable liquid with a flash point of 8℃, and a spontaneous ignition temperature of 436℃. The volume fraction of methanol steam within the explosion range in the air is 6-36.5 percent.
