Move the victim into fresh air. If breathing is difficult, give oxygen. If not breathing, give artificial respiration and consult a doctor immediately. Do not use mouth to mouth resuscitation if the victim ingested or inhaled the chemical.
Take off contaminated clothing immediately. Wash off with soap and plenty of water. Consult a doctor.
Rinse with pure water for at least 15 minutes. Consult a doctor.
Rinse mouth with water. Do not induce vomiting. Never give anything by mouth to an unconscious person. Call a doctor or Poison Control Center immediately.
SYMPTOMS: Large oral doses in humans have provoked burning sensation, facial pressure, chest pains, dyspnea, somnolence, hallucinations, distorted perceptions, nause and vomiting. Susceptible individuals may experience an allergic response. ACUTE/CHRONIC HAZARDS: This compound emits toxic fumes when heated to decomposition. (NTP, 1992)
SRP Idiosyncratic reaction/: No decontamination measures have been reported. No antidotes exist. Supportive measures: Follow with ECG and cardiac evaluation if chest pain persists. Alert patient to avoid foods with MSG.
Fires involving this compound should be controlled with a dry chemical, carbon dioxide or Halon extinguisher. (NTP, 1992)
Flash point data are not available for this chemical, but it is probably combustible. (NTP, 1992)
Wear self-contained breathing apparatus for firefighting if necessary.
Avoid dust formation. Avoid breathing mist, gas or vapours.Avoid contacting with skin and eye. Use personal protective equipment.Wear chemical impermeable gloves. Ensure adequate ventilation.Remove all sources of ignition. Evacuate personnel to safe areas.Keep people away from and upwind of spill/leak.
Prevent further spillage or leakage if it is safe to do so. Do not let the chemical enter drains. Discharge into the environment must be avoided.
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.
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.
Store in airtight containers.

Ensure adequate ventilation. Handle in accordance with good industrial hygiene and safety practice. Set up emergency exits and the risk-elimination area.
Wear tightly fitting safety goggles with side-shields conforming to EN 166(EU) or NIOSH (US).
Wear fire/flame resistant and impervious clothing. Handle with gloves. Gloves must be inspected prior to use. Wash and dry hands. The selected protective gloves have to satisfy the specifications of EU Directive 89/686/EEC and the standard EN 374 derived from it.
If the exposure limits are exceeded, irritation or other symptoms are experienced, use a full-face respirator.

Acidic salts, such as MONOSODIUM GLUTAMATE, are generally soluble in water. The resulting solutions contain moderate concentrations of hydrogen ions and have pH's of less than 7.0. They react as acids to neutralize bases. These neutralizations generate heat, but less or far less than is generated by neutralization of inorganic acids, inorganic oxoacids, and carboxylic acid. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible. Many of these compounds catalyze organic reactions.

The following genera of bacteria have the enzymatic capability to degrade L-glutamic acid: Micrococcus, Brevibacterium, Corynebacterium, Arthrobacter and Microbacterium(1). Grab sample data, using radiolabeled monosodium glutamate and deep sea water and coastal estuarine water with their respective sediments, demonstrated that the glutamate ion should biodegrade rapidly in the environment(2). Samples were incubated for 19 days at temperatures from -1.5 to 1.5 deg C. Rates of uptake were measured with overall utilization of the substrate. At a concentration of 240 ug/120 mL, 5.46 ug monosodium glutamate/day was incorporated into the microbial population while a total of 16.07 ug/day were metabolized. At a concentration of 600 ug/120 mL, 12.0 ug monosodium glutamate/day was incorporated into the microbial population while a total of 40.15 ug/day were metabolized. At a concentration of 1200 ug/120 mL, 23.19 ug monosodium glutamate/day was incorporated into the microbial population while a total of 84.46 ug/day were metabolized. At a concentration of 3600 ug/120 mL, 36.76 ug monosodium glutamate/day was incorporated into the microbial population while a total of 123.46 ug/day was metabolized(2).
An estimated BCF of 1 was calculated in fish for monosodium glutamate(SRC), using a water solubility of 3.85X10+5 mg/L(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 monosodium glutamate is estimated as 4(SRC), using a water solubility of 3.85X10+5 mg/L(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that monosodium glutamate is expected to have very high mobility in soil.

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.
