Fire Hazard
Flash point data for this chemical are not available; however, it is probably combustible. (NTP, 1992)
Health Hazard
SYMPTOMS: Symptoms of exposure to this compound include impaired liver function, dryness of the skin, anorexia, nausea, vomiting, diarrhea, activation of peptic ulcers, hepatic disease, hyperuricemia and circulatory collapse (after rapid intravenous injection). It may cause temporary flushing and a feeling of warmth, temporary headache, itching, tingling, skin rash and allergies. It may also cause burning of the skin, face and upper trunk and elevation of serum bilirubin. Other symptoms include mild irritation of upper respiratory tract and gastrointestinal disturbances. It may cause dyspepsia, hyperpigmentation, decrease in excretion of bromosulfophthalein, increase of plasma transaminase activities, incidence of acute gouty arthritis, acanthosis nigricans, hyperglycemia, increased vasodilation and cystoid edema of the macula. It may also cause furunculosis and other skin lesions, hypotension, abdominal cramps, mild diabetes and urticaria. Other symptoms include pruritus, toxic amblyopia, jaundice and decreased glucose tolerance.

ACUTE/CHRONIC HAZARDS: This compound may cause mild irritation to the upper respiratory tract. When heated to decomposition it may emit toxic fumes of NOx. (NTP, 1992)
Reactivity Profile
NICOTINIC ACID is incompatible with strong oxidizers. It is also incompatible with sodium nitrite. (NTP, 1992)
Belongs to the Following Reactive Group(s)

Response Recommendations

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 spill this chemical, you should dampen the solid spill material with water, then transfer the dampened material to a suitable container. Use absorbent paper dampened with water to pick up any remaining material. Seal your contaminated clothing and the absorbent paper in a vapor-tight plastic bag for eventual disposal. Wash all contaminated surfaces 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)
