First Aid Measures

Ingestion
Never give anything by mouth to an unconscious person. Get medical aid. Do NOT induce vomiting. If conscious and alert, rinse mouth and drink 2-4 cupfuls of milk or water.
Inhalation
Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid. DO NOT use mouth-to-mouth respiration.
Skin
Flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. Get medical aid if irritation develops or persists. Wash clothing before reuse.
Eyes
Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid.

Handling and Storage

Storage
Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances.
Handling
Wash thoroughly after handling. Minimize dust generation and accumulation. Avoid contact with eyes, skin, and clothing. Keep container tightly closed. Avoid ingestion and inhalation. Use with adequate ventilation. Wash clothing before reuse.

Hazards Identification

Inhalation

Exposure Controls/Personal Protection

Personal Protection
Eyes: Wear appropriate protective eyeglasses or chemical safety goggles as described by OSHA's eye and face protection regulations in 29 CFR 1910.133 or European Standard EN166. Skin: Wear appropriate protective gloves to prevent skin exposure. Clothing: Wear appropriate protective clothing to prevent skin exposure.
Respirators
A respiratory protection program that meets OSHA's 29 CFR 1910.134 and ANSI Z88.2 requirements or European Standard EN 149 must be followed whenever workplace conditions warrant a respirator's use.
Exposure Effects
Effects may be delayed.
Exposure limit(s)
TLV (as TWA): ppm; 5 mg/m3 (ACGIH 1992-1993) OSHA PEL: TWA 5 mg/m3 NIOSH REL: TWA 5 mg/m3 NIOSH IDLH: 4000 mg/m3
Poison Class
4

Fire Fighting Measures

Flash Point
160
Autoignition
390
Fire Fighting
Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Containers may explode when heated. Combustible material when exposed to heat or flame. Extinguishing media: Water or foam may cause frothing. Cool containers with flooding quantities of water until well after fire is out. In case of fire use water spray, dry chemical, carbon dioxide, or appropriate foam.
Upper exp. limit
2.5
Lower exp. limit
.5
Fire Potential
This material is combustible.

Accidental Release Measures

Small spills/leaks
Vacuum or sweep up material and place into a suitable disposal container. Clean up spills immediately, using the appropriate protective equipment. Avoid generating dusty conditions. Remove all sources of ignition. Provide ventilation.

Stability and Reactivity

Stability
Stable at room temperature in closed containers under normal storage and handling conditions.
Incompatibilities
Strong acids, strong bases, strong oxidizing agents.
Decomposition
Carbon monoxide, carbon dioxide, acrid smoke and fumes.
Combustion Products
The thermal decomposition of dibutyl phthalate was carried out in a flow system @ 250-500 C. The major products were 1-butene, butanol and phthalic anhydride.
