Fresh air, rest.
Remove contaminated clothes. Rinse skin with plenty of water or shower.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Rinse mouth.
SYMPTOMS: Symptoms of exposure to this compound may include irritation of the skin, eyes and respiratory tract. Ingestion of large amounts may cause gastrointestinal distress and diarrhea. Exposure may also cause the formation of renal calcium oxalate calculi. There have been cases of allergic reaction with eczema, urticaria and asthma. The mucolytic effect of this compound might render the cervical mucus less permeable to spermatozoa. ACUTE/CHRONIC HAZARDS: This compound may cause irritation of the skin, eyes and respiratory tract. When heated to decomposition it emits acrid smoke and irritating fumes. (NTP, 1992)
All sources of vitamin C should be withdrawn and treatment for gastrointestinal symptoms provided, including antiemetics. If significant hemolysis occurs, intravenous hydration to maintain urine output should be administered. Monitoring renal function should be performed, and rarely, transfusion of packed red blood cells is required.
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)
Flash point data for this chemical are not available; however, it is probably combustible. (NTP, 1992)
Use water spray, powder.
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. Wash away remainder with plenty of water.

Collect and arrange disposal. Keep the chemical in suitable and closed containers for disposal. Remove all sources of ignition. Use spark-proof tools and explosion-proof equipment. Adhered or collected material should be promptly disposed of, in accordance with appropriate laws and regulations.
NO open flames. Handling in a well ventilated place. Wear suitable protective clothing. Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Use non-sparking tools. Prevent fire caused by electrostatic discharge steam.
Separated from strong oxidants and strong bases.Solutions of ascorbic acid are rapidly oxidized in air and in alkaline media; the drug should be protected from air and light.

The substance is a strong reducing agent. It reacts violently with oxidants. The solution in water is a medium strong acid.
Stable to air when dry; impure preparation and in many natural products vitamin oxidizes on exposure to air and light. Aqueous solutions are rapidly oxidized by air, accelerated by alkalies, iron, copper
L-ASCORBIC ACID is a lactone. Reacts as a relatively strong reducing agent and decolorizes many dyes. Forms stable metal salts. Incompatible with oxidizers, dyes, alkalis, iron and copper. Also incompatible with ferric salts and salts of heavy metals, particularly copper, zinc and manganese (NTP, 1992).

No indication can be given about the rate at which a harmful concentration of this substance in the air is reached on evaporation at 20°C.
AEROBIC: Using a mixed microbial consortia enriched from untreated sewage samples collected in the vicinity of a primary treatment plant in Delhi, India, L-ascorbic acid exhibited 36.7 mg/L BOD, suggesting moderate susceptibility to biodegradation(1).
An estimated BCF of 3 was calculated in fish for L-ascorbic acid(SRC), using a log Kow of -1.85(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).
The Koc of L-ascorbic acid is estimated as 10(SRC), using a log Kow of -1.85(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that L-ascorbic acid is expected to have very high mobility in soil. The pKa of L-ascorbic acid is 4.70(4), indicating that this compound will exist almost entirely in the anion form in the environment and anions generally do not adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(5).

The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.
Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
