SECTION 5: Fire-fighting measures
5.1Suitable extinguishing media
Water in straight hose stream will scatter and spread fire and should not be used.
5.2Specific hazards arising from the chemical
Excerpt from ERG Guide 129 [Flammable Liquids (Water-Miscible / Noxious)]: HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. Those substances designated with a (P) may polymerize explosively when heated or involved in a fire. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water. (ERG, 2016)
5.3Special protective actions for fire-fighters
Use AFFF, alcohol-resistant foam, dry powder, carbon dioxide. In case of fire: keep drums, etc., cool by spraying with water.
SECTION 6: Accidental release measures
6.1Personal precautions, protective equipment and emergency procedures
Personal protection: filter respirator for organic gases and vapours adapted to the airborne concentration of the substance. Ventilation. Remove all ignition sources. Collect leaking and spilled liquid in sealable metal or glass containers as far as possible. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations.
6.2Environmental precautions
Personal protection: filter respirator for organic gases and vapours adapted to the airborne concentration of the substance. Ventilation. Remove all ignition sources. Collect leaking and spilled liquid in sealable metal or glass containers as far as possible. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations.
6.3Methods and materials for containment and cleaning up
1. Remove all ignition sources. 2. Ventilate area of spill or leak. 3. For small quant, absorb on paper towels. Evaporate in a safe place (such as a fume hood). Allow sufficient time for evaporating vapors to completely clear the hood ductwork. Burn the paper in a suitable location away from combustible materials. Large quantities can be collected and atomized in a suitable combustion chamber. Butyl acetate should not be allowed to enter a confined space, such as a sewer, because of the possibility of an explosion.
SECTION 7: Handling and storage
7.1Precautions for safe handling
NO open flames, NO sparks and NO smoking. Above 22°C use a closed system, ventilation and explosion-proof electrical equipment. Handling in a well ventilated place. Wear suitable protective clothing.

SECTION 10: Stability and reactivity
10.1Reactivity
1700 PPM [IDLH based on 10% of the lower explosive limit for safety considerations even though the relevant toxicological data indicated that irreversible health effects or impairment of escape existed only at higher concentrations.]
Reacts with strong oxidants, strong acids and strong bases. This generates fire and explosion hazard. Attacks many plastics and rubber.
10.2Chemical stability
Heat /contributes to instability/.
10.3Possibility of hazardous reactions
Flammable liquid.The vapour is heavier than air and may travel along the ground; distant ignition possible.BUTYL ACETATE is an ester. Esters react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides. Attacks many plastics. [Handling Chemicals Safely 1980. p. 233].
10.4Conditions to avoid
10.5Incompatible materials
Contact with nitrates, strong oxidizers, strong alkalies, and strong acids may cause fires and explosions.
