Potential Health Effects
----------------------------------
Inhalation:
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.
Ingestion:
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 death.
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.
4. First Aid Measures
Inhalation:
Remove to fresh air. If not breathing, give
artificial respiration. If breathing is difficult, give oxygen. Get medical
attention.
Ingestion:
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 all
suspected cases of sodium carbonate poisoning. Perform blood analysis to
determine if dehydration, acidosis, or other electrolyte imbalances occurred.
5. Fire Fighting Measures
Fire:
Not considered to be a fire hazard.
Explosion:
Not considered an explosion hazard, but sodium
carbonate may explode when applied to red-hot aluminum.
Fire
Extinguishing Media:
Use any means suitable for extinguishing
surrounding fire.
Special Information:
Use protective clothing
and breathing equipment appropriate for the surrounding fire.
6. Accidental Release Measures
Ventilate area of leak or spill. 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.
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 hazardous when empty since they
retain product residues (dust, solids); observe all warnings and precautions
listed for the product.
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 the dust or mist is apparent, a half-face dust/mist
respirator may be worn. For emergencies or instances where the exposure levels
are not known, use a full-face positive-pressure, 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.
