Section
6: Accidental Release Measures
Small
Spill:Use appropriate
tools to put the spilled solid in a convenient waste disposal container. If
necessary: Neutralize the residue with a dilute solution of acetic acid. Finish
cleaning by spreading water on the contaminated surface and dispose of according
to local and regional authority requirements.
Large
Spill:Use a shovel to put
the material into a convenient waste disposal container. Neutralize the residue
with a dilute solution of acetic acid. Finish cleaning by spreading water on the
contaminated surface and allow to evacuate through the sanitary system.
Section
7: Handling and Storage
Precautions:Do
not ingest. Do not breathe dust. Wear suitable protective clothing. In case of
insufficient ventilation, wear suitable respiratory equipment. If ingested, seek
medical advice immediately and show the container or the label. Avoid contact
with skin and eyes. Keep away from incompatibles such as acids.
Storage:Hygroscopic.
Keep container tightly closed. Keep container in a cool, well-ventilated area.
Do not store above 24°C (75.2°F). Hygroscopic
Section
8: Exposure Controls/Personal Protection
Engineering
Controls:Use process
enclosures, local exhaust ventilation, or other engineering controls to keep
airborne levels below recommended exposure limits. If user operations generate
dust, fume or mist, use ventilation to keep exposure to airborne contaminants
below the exposure limit.
Personal
Protection:Splash goggles.
Lab coat. Dust respirator. Be sure to use an approved/certified respirator or
equivalent. Gloves.
Personal
Protection in Case of a Large Spill:Splash
goggles. Full suit. Dust respirator. Boots. Gloves. A self contained breathing
apparatus should be used to avoid inhalation of the product. Suggested
protective clothing might not be sufficient; consult a specialist BEFORE
handling this product.

Conditions
of Instability: Incompatible
materials, moisture
Incompatibility
with various substances:
Reactive
with acids. Slightly reactive to reactive with moisture.

(Lowest Published Lethal Dose) [Man] - Route: Oral; Dose: 714 mg/kg
Special
Remarks on Chronic Effects on Humans: May
cause adverse reproductive effects based on animal test data
Special
Remarks on other Toxic Effects on Humans:
Acute
Potential Health Effects: Skin: Causes skin irritation with possible burns
depending on the concentration, site (abraded or intact skin), and duration of
exposure. Eyes: Causes eye irritation and possible burns. Concentrated solutions
may cause permanent corneal injury (permanent corneal opacity). Ingestion:
Sodium carbonate ingestion may cause irritation of the digestive tract resulting
in nausea, vomiting, diarrhea, thirst, abdominal pain depending on concentration
and amount ingested.
May
also affect the cardiovascular system . Inhalation: Dust may cause respiratory
tract and mucous membrane irritation with coughing and shortness of breath
(dyspnea), pulmonary edema. Chronic Potential Health Effects: Chronic inhalation
may result in decreased pulmonary function, nasal congestion, nosebleeds,
perforation of the nasal septum. Other effects of chronic exposure are skin
(dermatitis and ulceration), and gastrointestinal complaints. However, the
effects of chronic exposure seem to be reversible if exposure is decreased.
