First Aid Measures

Ingestion
DO NOT INDUCE VOMITING. If the victim is conscious and not convulsing, give 1 or 2 glasses of water to dilute the chemical and IMMEDIATELY call a hospital or poison control center. Be prepared to transport the victim to a hospital if advised by a physician.
Inhalation
IMMEDIATELY leave the contaminated area; take deep breaths of fresh air. If symptoms (such as wheezing, coughing, shortness of breath, or burning in the mouth, throat, or chest) develop, call a physician and be prepared to transport the victim to a hospital. Provide proper respiratory protection to rescuers entering an unknown atmosphere. Whenever possible, Self-Contained Breathing Apparatus (SCBA) should be used.
Skin
IMMEDIATELY flood affected skin with water while removing and isolating all contaminated clothing. Gently wash all affected skin areas thoroughly with soap and water. If symptoms such as redness or irritation develop, IMMEDIATELY call a physician and be prepared to transport the victim to a hospital for treatment.
Eyes
First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop.

Handling and Storage

Storage
Keep tightly closed in a cool place in a tightly closed container.
Handling
All chemicals should be considered hazardous. Avoid direct physical contact. Use appropriate, approved safety equipment. Untrained individuals should not handle this chemical or its container. Handling should occur in a chemical fume hood.

Hazards Identification

Inhalation
Respiratory irritation is uncommon, but possible.
Skin
Dermal irritation may sometimes develop.
Eyes
Can cause eye irritation. Symptoms include stinging, tearing, redness, and swelling of eyes.
Ingestion
Gi tract or esophageal irritation may occur.

Exposure Controls/Personal Protection

Personal Protection
May be some need for skin protection. Protection of workers in operations where phthalates are used is usually determined by precautions prompted by presence of more toxic chemicals.
Respirators
If overexposure has been determined or documented, a NIOSH/MSHA jointly approved air supplied respirator is advised in absence of proper environmental control. OSHA regulations also permit other NIOSH/MSHA respirators under specified conditions.
Exposure Effects
Central nervous system depression may occur with ingestion of large amounts.
Poison Class
-

Fire Fighting Measures

Flash Point
224
Fire Fighting
Fires involving this material should be controlled using a dry chemical, carbon dioxide or Halon extinguisher.
Fire Potential
This chemical is combustible.

Accidental Release Measures

Small spills/leaks
If you spill this chemical, use absorbent paper to pick up all liquid spill material. Your contaminated clothing and absorbent paper should be sealed in a vapor-tight plastic bag for eventual disposal. Solvent wash all contaminated surfaces with alcohol followed by washing with a strong 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.

Stability and Reactivity

Incompatibilities
Reacts exothermically with acids to generate isononyl alcohol and phthalic acid Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products Interaction with caustic solutions.
Stability
Stable.
Decomposition
Carbon dioxide and carbon monoxide.
