Health Rating : 1 - Slight
Flammability Rating : 1 - Slight
Reactivity Rating : 2 - Moderate
Contact Rating : 3 - Severe (Life)
Storage Color Code : Green (General Storage)
Potential Health Effects
Inhalation of dust may cause irritation to the respiratory tract. Symptoms from excessive
inhalation of dust may include coughing and difficult breathing. Excessive contact is known to
cause damage to the nasal septum.
Sodium carbonate is only slightly toxic, but large doses may be corrosive to the gastro-intestinal
tract where symptoms may include severe abdominal pain, vomiting, diarrhea, collapse and
Skin Contact:
Excessive contact may cause irritation with blistering and redness. Solutions may cause severe
irritation or burns.

Eye Contact:
Contact may be corrosive to eyes and cause conjuctival edema and corneal destruction. Risk
of serious injury increases if eyes are kept tightly closed. Other symptoms may appear from
absorption of sodium carbonate into the bloodstream via the eyes.
Chronic Exposure:
Prolonged or repeated skin exposure may cause sensitization.
Aggravation of Pre-existing Conditions:
No information found.

Section 4 : First Aid Measures

Remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give
oxygen. Get medical attention.
If swallowed, DO NOT INDUCE VOMITING. Give large quantities of water. Never give anything by
mouth to an unconscious person. Get medical attention immediately.
Skin Contact:
Immediately flush skin with plenty of soap and water for at least 15 minutes. Remove
contaminated clothing and shoes. Get medical attention. Wash clothing before reuse.
Thoroughly clean shoes before reuse.
Eye Contact:
Immediately flush eyes with plenty of water for at least 15 minutes, lifting lower and upper eyelids
occasionally. Get medical attention immediately.
Note to Physician:
Consider endoscopy in al suspected cases of sodium carbonate poisoning. Perform blood
analysis to determine if dehydration, acidosis, or other electrolyte imbalances occurred.

Section 5: Fire Fighting Measures

Not considered to be a fire hazard.
Not considered an explosion hazard, but sodium carbonate may explode when applied to
Fire Extinguishing Media:
Use any means suitable for extinguishing surrounding fire.
Special Information:
Use protective clothing and breathing equipment appropriate for the surrounding fire.

Section 6 : Accidental Release Measures
Ventilate area of leak or spil . Wear appropriate personal protective equipment as specified in
Section 8. Spills: Sweep up and containerize for reclamation or disposal. Vacuuming or wet
sweeping may be used to avoid dust dispersal.

Section 7 : Handling and Storage
Keep in a tightly closed container, stored in a cool, dry, ventilated area. Protect against physical
damage. Isolate from incompatible substances. Containers of this material may be
hazardouswhen empty since they retain product residues (dust, solids); observe all warnings and
precautions listed for the product.

Section 8 : Exposure Controls/Personal Protection
Airborne Exposure Limits:
None established.
Ventilation System:
A system of local and/or general exhaust is recommended to keep employee exposures as low
as possible. Local exhaust ventilation is generally preferred because it can control the emissions
of the contaminant at its source, preventing dispersion of it into the general work area. Please
refer to the ACGIH document, Industrial Ventilation, A Manual of Recommended Practices, most
recent edition, for details.
Personal Respirators (NIOSH Approved):
For conditions of use where exposure to dust or mist is apparent and engineering controls are
not feasible, a particulate respirator (NIOSH type N95 or better filters) may be worn. If oil particles
(e.g. lubricants, cutting fluids, glycerine, etc.) are present, use a NIOSH type R or P filter. For
emergencies or instances where the exposure levels are not known, use a full-face
air-supplied respirator. WARNING: Air-purifying respirators do not protect workers in
oxygen-deficient atmospheres.
Skin Protection:
Wear protective gloves and clean body-covering clothing.
Eye Protection:
Use chemical safety goggles and/or full face shield where dusting or splashing of solutions is
possible. Maintain eye wash fountain and quick-drench facilities in work area.
