(closed-cup)
FLAMMABLE LIMITS IN AIR; % BY VOL. LOWER: 4%
FLAMMABLE LIMITS IN AIR; % BY VOL. UPPER: 16%
SPECIAL FIRE FIGHTING PROCEDURES & PRECAUTIONS:
Use CO2, dry powder, vapourizing liquids, water spray. The
addition of water will increase the intensity of the flames. Wear protective
clothing and self-contained breathing apparatus to protect against corrosive
vapours.

Section IX - REGULATORY CONTROLS
DEPT. OF TRANSPORTATION: Regulated under the
Transport of Dangerous Goods Act.
DOT CLASSIFICATION: Class 8 (9.2) UN 2789
DOT PROPER SHIPPING NAME: Acetic acid, glacial
OTHER DOT INFORMATION: Packing group II
WHMIS CLASSIFICATION: B3, E
OTHER REGULATORY REQUIREMENT: n. av.
Section X - PRECAUTIONS: HANDLING, STORAGE & USAGE
Handle with extreme caution, always wear protective
clothing. NEVER add water to acid, to dilute, slowly add acid to water.
Adding acetic acid to water produces much heat. Can react vigourously with
oxidising materials (especially chromic acid, sodium peroxide, nitric acid).
Causes vigourous exothermic polymerisation with acetaldehyde. Acetic acid
vapour can ignite with potassium tert-butoxide.
