SPECIAL HAZARD ALERT: Laboratory accidents involving methyl alcohol occur when vapor in the air ignites and travels back to the source, causing a flash fire. Always cap the bottle of methyl alcohol and remove it from the area prior to performing any demon- stration involving open flames, sparks or heat. Use only a small amount and always perform demonstrations behind a safety shield. Please call or email us to request Flinn Safety Fax Publication No. 10497, Methyl Alcohol Safety, for more detailed safety information and instructions.
Storage: Organic #2 in a dedicated flammables cabinet. If one is not available, store in a Flinn Saf-Stor TM Can.
Disposal: #18a. U-Listed (U154); purchase small amounts for effec- tive inventory control.
Shelf Life: Good if stored safely.
Soluble: Miscible with water and alcohol.
Color and Odor: Colorless liquid with alcohol odor.
CAS No. 67-56-1
Safety Purchase Suggestion: Please consider the use of anhydrous ethyl alcohol (E0012, etc.) as a substitute. Ethyl alcohol is a good substitute for methyl alcohol for most laboratory experiments and as a burner fuel. Avoid purchasing 20-liter cans of this substance unless you have approved, dedicated flammables storage.

Two Vital Questions to Ask Before Use of Any Chemicals
1. How can this substance hurt me?
2. How can I protect myself against this substance?
Those two simple questions should be considered before you undertake the use of any substance either at home or in the lab. Read the label and the Safety Data Sheet (SDS). The answers
to Question 2 will be found in this Flinn Scientific Catalog/ Reference Manual, on our bottle labels and on the SDSs.
