Methanol

CAS RN: 67-56-1

Storage Conditions

Keep container tightly closed in a dry and well-ventilated place. Containers which are opened must be carefully resealed and kept upright to prevent leakage.
When large amounts of methanol are stored in enclosed 14 Methanol spaces, monitoring by means of lower explosion limit monitors is desirable.
Permanently installed fire-extinguishing equipment should be provided in large storage facilities. Water cannons are generally installed in storage tank farms to cool steel constructions and neighboring tanks in the event of fire. Large tanks should have permanently installed piping systems for alcohol-resistant fire-extinguishing foams.
Small-Scale Storage. Small amounts (
Large-Scale Storage. Large amounts of methanol are stored in tanks that correspond in design and construction to those used for petroleum products; cylindrical tanks with capacities from a few hundred cubic meters to more than 100,000 cubic meters are normally used. With fixed-roof tanks, special measures (e.g., nitrogen blanketing) should be adopted to prevent the formation of an ignitable atmosphere in the space above the liquid surface. Emission of methanol may occur if the level fluctuates. To avoid these problems, large tanks are often equipped with a scrubber system or floating roofs; attention should therefore be paid to guard against entry of rainwater.
Store in a flammable liquid storage area or approved cabinet away from ignition sources and corrosive and reactive materials ... Store in tightly closed containers in a cool, well ventilated area away from heat.
