Hazards and Protection.
Storage
Keep in a cool, dry, dark location in a tightly sealed container or cylinder. Keep away from incompatible materials, ignition sources and untrained individuals. Secure and label area. Protect containers/cylinders from physical damage.
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.
Protection
Use of garments to protect workmen from irritation due to contact with phthalic anhydride which is used in the manufacturing process of phthalic acid esters; gloves should be used to prevent contamination of the hand and lower arm. Synth of phthalates require good ventilation in order to minimize contamination of air with phthalic anhydride or alcohols. There may be also some need for skin protection. Handling mineral acids used as catalysts requires ordinary precautions.
Respirators
Use NIOSH/MSHA approved respirator appropriate for exposure of concern.
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
No data.
Incompatibilities
Reacts 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 Interaction with caustic solutions.

Fire.
Flash Point,°C
235
Fire fighting
Do not use water to extinguish fire. .Fire Extinguishing Agents: Dry chemical, alcohol foam, or carbon dioxide.
Hazards
Irritating vapors and toxic gases, such as carbon dioxide and carbon monoxide, may be formed when involved in fire.
Combustion products
Irritating vapors and toxic gases, such as carbon dioxide and carbon monoxide, may be formed when involved in fire.

Poison_Class
4
Exposure effects
Central nervous system depression may occur with ingestion of large amounts.
   Ingestion
Gi tract or esophageal irritation may occur.
   Inhalation
Respiratory irritation is uncommon, but possible.
   Skin
Dermal irritation may sometimes develop.

First aid
 
   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.
