POTENTIAL FIRE OR EXPLOSION HAZARDS - EMERGENCY RESPONSE GUIDEBOOK, GUIDE 129 (ERG, 2004)

tert-Butyl acetate is a flammable liquid, and a moderate fire hazard (Lewis, 1993) NIOSH, 1995).

It is incompatible with strong alkalis, strong acids, nitrates, and strong oxidizers; contact may cause explosion and fire (ACGIH, 1991) NIOSH, 1995).

This compound releases irritating fumes and acrid smoke (including, carbon monoxide and soot) when heated to decomposition (ACGIH, 1991; Lewis, 1992).

tert-Butyl acetate is heavier than air and can flash back along a vapor trail: It will float on water (AAR, 1994; (CHRIS , 1995).

Not Listed

CAUTION: All these products have a very low flash point: Use of water spray when fighting fire may be inefficient.

Dry chemical, CO2, water spray or alcohol-resistant foam.

Do not use dry chemical extinguishers to control fires involving nitromethane or nitroethane.

Water spray, fog or alcohol-resistant foam.

Do not use straight streams.

Move containers from fire area if you can do it without risk.

Fight fire from maximum distance or use unmanned hose holders or monitor nozzles.

Cool containers with flooding quantities of water until well after fire is out.

Withdraw immediately in case of rising sound from venting safety devices or discoloration of tank.

ALWAYS stay away from tanks engulfed in fire.

For massive fire, use unmanned hose holders or monitor nozzles; if this is impossible, withdraw from area and let fire burn.

Not Listed

Water can be used to cool exposed containers as well as to knock down vapor. Apply water from as far a distance as is possible. Avoid using solid streams of water, as this may spread the fire: Use water in a mist or fog (AAR, 1994; (CHRIS , 1995; Lewis, 1992; OHM/TADS , 1995).

Consider initial downwind evacuation for at least 300 meters (1000 feet).

If tank, rail car or tank truck is involved in a fire, ISOLATE for 800 meters (1/2 mile) in all directions; also, consider initial evacuation for 800 meters (1/2 mile) in all directions.

CALL Emergency Response Telephone Number on Shipping Paper first. If Shipping Paper not available or no answer, refer to appropriate telephone number:

For additional details see the section entitled "WHO TO CALL FOR ASSISTANCE" under the ERG Instructions.

As an immediate precautionary measure, isolate spill or leak area for at least 50 meters (150 feet) in all directions.

Keep unauthorized personnel away.

Stay upwind.

Keep out of low areas.

Ventilate closed spaces before entering.

Evacuate people to a minimum distance of 200 feet upwind and 1000 feet downwind (OHM/TADS , 1995).

SPILL OR LEAK PRECAUTIONS - EMERGENCY RESPONSE GUIDEBOOK, GUIDE 129 (ERG, 2004)

RECOMMENDED PROTECTIVE CLOTHING - EMERGENCY RESPONSE GUIDEBOOK, GUIDE 129 (ERG, 2004)

In situ amelioration procedures: If possible, contain the leak and shut off or reduce the flow rate. In water spills, floating booms may be helpful. The partially dissolved material can be adsorbed to activated carbon. Vacuum systems, dredges, and bottom pumps may be employed to remove the sorbent from the bottom (or) the floating portion may be pumped out, transferred to a gravity separation tank, and then passed through a dual media filtration system and an activated carbon filter. If a large amount of unabsorbed material remains, ignition of this remaining material, by the local fire department, may be considered. In this instance, make sure all local public safety, health, water, and air authorities are notified (OHM/TADS , 1995).

LAND SPILL (for butyl acetate): Dig a pit to contain the material (size of pit dependent on the size of the spill). Dike the flow with foamed concrete, sand bags, foamed polyurethane, or soil. Absorb liquid with cement powder or fly ash. Utilize the appropriate foam to lower the vapor and fire risks (AAR, 1994).

WATER SPILL (for butyl acetate): Use spill control booms or/and any natural barriers to contain leak. If approved by the EPA for this agent, use a surface active agent (eg, alcohols, detergents, soaps). Employ a universal gelling agent. If material is dissolved at a concentration of 10 ppm or greater, apply activated charcoal at ten times the spilled amount. Utilize suction hoses to remove trapped material. Use mechanical dredges to remove masses of precipitates and pollutants (AAR, 1994).

AIR SPILL (for butyl acetate): Apply water spray to knock down vapors (AAR, 1994).

LARGE SPILL PRECAUTIONS - EMERGENCY RESPONSE GUIDEBOOK, GUIDE 129 (ERG, 2004)

When diluted, tert-butyl acetate can be treated biologically in a municipal sewage treatment plant (OHM/TADS , 1995).

Waste management activities associated with material disposition are unique to individual situations. Proper waste characterization and decisions regarding waste management should be coordinated with the appropriate local, state, or federal authorities to ensure compliance with all applicable rules and regulations.

Apply a sorbent (straw, sawdust, peat) to the contained material. Remove this contaminated sorbent and place in a sealed, impervious container. Incineration of this material is best; any residue (solid, liquid, or sludge) has to be disposed in accordance with all applicable federal, state, and local regulations. If an approved chemical incinerator is not available, burial in a chemical waste landfill is acceptable (OHM/TADS , 1995).

When released to the atmosphere, tert-butyl acetate will exist largely as vapor. Vapor-phase reaction with photochemically produced hydroxyl radicals is expected to be the most important degradation process; estimated half-life is 26 days. Physical washout, by rain, may be possible (HSDB , 1995).
