First Aid MeasuresBack to Contents

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.

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.

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.

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. If symptoms (such as redness or irritation) develop, immediately transport the victim to a hospital.

Accidental Release MeasuresBack to Contents
【Small spills/leaks】

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.
Stability and ReactivityBack to Contents

Aq solution are unstable and subject to quick oxidation by air @ pH greater than 6.0 Relatively stable in air on exposure to light it gradually darkens ascorbic acid gradually darkens upon exposure to light; however, slight coloration does not impair the therapeutic activity of ascorbic acid injection. Solutions of ascorbic acid are rapidly oxidized in air and in alkaline media; the drug should be protected from air and light. In concentrations greater than 100 mgml ascorbic acid may undergo decomposition with the production of carbon dioxide. Since increased pressure may develop after prolonged storage, ampuls containing ascorbic acid injection should be opened carefully. Ascorbic acid.

Reacts as bases to neutralize acids.

Carbon dioxide and carbon monoxide, nitrogen oxides, various hydrocarbons.
