General Description
PHYSICAL DESCRIPTION: Clear colorless to amber liquid with a sweet aromatic odor. (NTP, 1992)
Hazards
Reactivity Alerts
Air & Water Reactions
Highly flammable. Water soluble.
Fire Hazard
This chemical is combustible. (NTP, 1992)
Health Hazard
SYMPTOMS: This compound may cause irritation of the skin and eyes. It may also cause irritation of the mucous membranes and upper respiratory tract. Exposure to high concentrations of this compound may cause narcosis. It is neurotoxic. It may cause peripheral neuropathy. Discoloration of the skin has been reported. Chronic exposure may produce severe neurologic damage and testicular germinal cell damage. It may affect formed elements of blood after prolonged exposure. Chronic exposure may also cause severe impairment of the central and peripheral nervous systems, the testes and circulating elements in the blood.
ACUTE/CHRONIC HAZARDS: This compound is highly toxic by inhalation. It may be harmful by ingestion or skin absorption. The vapor or mist is irritating to the eyes, skin, mucous membranes and upper respiratory tract. High concentrations may cause narcosis. When heated to decomposition it emits toxic fumes of carbon monoxide and carbon dioxide. (NTP, 1992)
Reactivity Profile
2,5-HEXANEDIONE is incompatible with oxidizing agents. It is also incompatible with strong bases and strong reducing agents. (NTP, 1992)
Belongs to the Following Reactive Group(s)
Potentially Incompatible Absorbents

Response Recommendations
Isolation and Evacuation
Excerpt from 127
[Flammable Liquids (Water-Miscible)]:
IMMEDIATE PRECAUTIONARY MEASURE: Isolate spill or leak area for at least 50 meters (150 feet) in all directions.
LARGE SPILL: Consider initial downwind evacuation for at least 300 meters (1000 feet).
FIRE: 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. (ERG, 2020)
Firefighting
Fires involving this material can be controlled with a dry chemical, carbon dioxide or Halon extinguisher. A water spray may also be used. (NTP, 1992)
Non-Fire Response
SMALL SPILLS AND LEAKAGE: If you should spill this chemical, use absorbent paper to pick up all liquid spill material. Seal the absorbent paper, as well as any of your clothing which may be contaminated, in a vapor-tight plastic bag for eventual disposal. Wash any surfaces you may have contaminated 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 under ambient temperatures. (NTP, 1992)
Protective Clothing
RECOMMENDED RESPIRATOR: Where the neat test chemical is weighed and diluted, wear a NIOSH-approved half face respirator equipped with an organic vapor/acid gas cartridge (specific for organic vapors, HCl, acid gas and SO2) with a dust/mist filter. (NTP, 1992)

First Aid
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)
