SUCCINIC ANHYDRIDE reacts exothermically with water. Reactions are usually slow, but might become violent if local heating accelerates their rate. Acids accelerate the reaction with water. Incompatible with acids, strong oxidizing agents, alcohols, amines, and bases.
Decomposes on heating. This produces irritating fumes.
Reacts slowly with water. Insoluble in water.
Evaporation at 20 °C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed.
SAFETY
Fires involving this compound should be controlled using a Halon, carbon dioxide, or dry chemical extinguisher. A water spray may also be used. (NTP, 1992)
Use water spray, powder, alcohol-resistant foam, carbon dioxide.
Fresh air, rest.
Rinse and then wash skin with water and soap.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Rinse mouth. Give one or two glasses of water to drink.
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.;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.;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; if not available, use a level of protection greater than or equal to that advised under Protective Clothing.;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. If the victim is convulsing or unconscious, do not give anything by mouth, ensure that the victim's airway is open and lay the victim on his/her side with the head lower than the body. DO NOT INDUCE VOMITING. IMMEDIATELY transport the victim to a hospital. (NTP, 1992)
Remove all ignition sources. Sweep spilled substance into covered containers; if appropriate, moisten first to prevent dusting.
SMALL SPILLS AND LEAKAGE: If a spill of this chemical occurs, FIRST REMOVE ALL SOURCES OF IGNITION, then you should dampen the solid spill material with acetone and transfer the dampened material to a suitable container. Use absorbent paper dampened with acetone to pick up any remaining material. Seal your contaminated clothing and the absorbent paper in a vapor-tight plastic bag for eventual disposal. Solvent wash all contaminated surfaces with acetone followed by washing with a 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.;STORAGE PRECAUTIONS: You should store this material at ambient temperatures, and protect it from moisture. (NTP, 1992)
SRP: The most favorable course of action is to use an alternative chemical product with less inherent propensity for occupational exposure or environmental contamination. Recycle any unused portion of the material for its approved use or return it to the manufacturer or supplier. Ultimate disposal of the chemical must consider: the material's impact on air quality; potential migration in soil or water; effects on animal, aquatic, and plant life; and conformance with environmental and public health regulations.
Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting.
Prevent dispersion of dust!
Inhalation /exposure can be prevented by/ local exhaust or breathing protection. Skin /exposure can be prevented by/ protective gloves. Eye /exposure can be prevented by/ safety goggles, or eye protection in combination with breathing protection if powder. /from table/
Do not eat, drink, or smoke during work. /from table/
Wear safety goggles or eye protection in combination with breathing protection if powder.

A harmful concentration of airborne particles can be reached quickly when dispersed, especially if powdered.
Protective gloves.
TOXICITY
TERRESTRIAL FATE: The half-life for the hydrolysis of succinic anhydride is 4.3 minutes(SRC), based on a rate constant of 0.0027 1/sec at 25 °C(1). The major fate of succinic anhydride in soil is expected to be hydrolysis (SRC). Succinic anhydride is not expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 1.5X10-3 mm Hg(2).
AQUATIC FATE: The half-life for the hydrolysis of succinic anhydride is 4.3 minutes(SRC), based on a rate constant of 0.0027 1/sec at 25 °C(1). The major fate of succinic anhydride in aquatic environments is expected to be hydrolysis(SRC). Bioconcentration of succinic anhydride in aquatic organisms is unlikely due its rapid hydrolysis(SRC). Approximately 78% of the succinic anhydride added to activated sewage sludge was biodegraded within five days(2,3); however, hydrolysis is expected to be the principal fate of succinic anhydride in water(SRC).
ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), succinic anhydride, which has a vapor pressure of 1.5X10-3 mm Hg at 25 °C(2) is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase succinic anhydride is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals(SRC); the half-life for this reaction in air is estimated to be 70 days (SRC), calculated from its rate constant of 4.56X10-13 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3).
Dermatotoxin - Skin burns.
The substance can be absorbed into the body by inhalation and by ingestion.
Cough. Shortness of breath. Sore throat.
Redness. Pain.
Diarrhoea. Nausea. Vomiting.

Clicking on the "Testing Status" link will take the user to the status (i.e., in review, in progress, in preparation, on test, completed, etc.) and results of all the studies that the NTP has done on this chemical. [http://ntp-apps.niehs.nih.gov/ntp_tox/index.cfm?fuseaction=ntpsearch.searchresults&searchterm=108-30-5]
Adsorption of succinic anhydride in soil is unlikely due its rapid hydrolysis(1).
/SIGNS AND SYMPTOMS/ The substance irritates the eyes, the skin and the respiratory tract.
/SIGNS AND SYMPTOMS/ Inhalation /may cause/ cough, shortness of breath, sore throat. Skin or eye /exposure may cause/ redness, pain. Ingestion /may cause/ diarrhea, nausea, vomiting. /from table/
Succinic anhydride's production and use as a chemical reactant and intermediate, in the manufacture of pharmaceuticals and esters, as a hardener for resin(1), and as an acidulant in foods(2) may result in its release to the environment through various waste streams(SRC).
AEROBIC: Approximately 78% of the succinic anhydride added to activated sewage sludge at 50 ug/L was biodegraded within five days at 25 °C (1,2); however, hydrolysis is expected to be the principal fate of succinic anhydride in water and these results are probably for succinic acid, the hydrolysis product(SRC).
