7.1 Precautions for safe handling
SMALL SPILLS AND LEAKAGE: Should a spill occur while you are handling this chemical, FIRST REMOVE ALL SOURCES OF IGNITION, then you should dampen the solid spill material with 60-70% ethanol and transfer the dampened material to a suitable container. Use absorbent paper dampened with 60-70% ethanol to pick up any remaining material. Seal the absorbent paper, and any of your clothes, which may be contaminated, in a vapor-tight plastic bag for eventual disposal. Solvent wash all contaminated surfaces with 60-70% ethanol followed by washing with a soap and water solution. Do not reenter the contaminated area until the Safety Officer (or other responsible person) has verified that the area has been properly cleaned.

Sorbic acid's production and use as a preservative and antimicrobial agent for foods, animal feeds, tobacco, cosmetics, and pharmaceuticals may result in its release to the environment through various waste streams. Sorbic acid has been identified in tobacco smoke. It has been detected in Magnolia vine, Rowan berry and mountain ash berry. If released to the atmosphere, sorbic acid is expected to exist solely in the vapor phase in the ambient atmosphere based on a vapor pressure of 3.08X10-4 mm Hg at 25 °C. Vapor-phase sorbic acid is degraded in the atmosphere by reaction with nitrate radicals, ozone and photochemically-produced hydroxyl radicals with estimated half-lives of 1.4, 5.2 and 7.6 hours, respectively. Sorbic acid absorbs at wavelengths >290 nm and, therefore, may be susceptible to direct photolysis by sunlight. If released to soil, sorbic acid is expected to have very high mobility based upon an estimated Koc of 9. The pKa of sorbic acid is 4.76, indicating that this compound will exist almost entirely in the ani
