Potential Health Effects
----------------------------------
Inhalation:
Causes irritation to the respiratory tract. Symptoms may include
coughing, shortness of breath.
Ingestion:
Causes irritation to the gastrointestinal tract. Symptoms may
include nausea, vomiting and diarrhea. May have moderate toxic
effects if consumed in large enough quantities. Ingestion of large
amounts may be corrosive to mouth, throat and GI tract and produce
abdominal pains, vomiting, diarrhea, and circulatory collapse.
Skin Contact:
Contact with dry material causes irritation. In aqueous solution
it is a strong caustic and as such may have corrosive effects
on the skin.
Eye Contact:
Causes extreme irritation, redness, pain and possibly corneal
damage.
Chronic Exposure:
A chronic dermatitis may follow repeated contact with this substance.
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 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.
5. Fire Fighting Measures
Fire: Not considered to be a fire hazard.
Explosion:
Not considered to be an explosion hazard. An explosion occurred
after mixing sodium hydrosulfite, aluminum powder, potassium carbonate
and benzaldehyde.
Fire Extinguishing Media:
Use any means suitable for extinguishing surrounding fire.
Special Information:
In the event of a fire, wear full protective clothing and NIOSH-approved
self-contained breathing apparatus with full facepiece operated
in the pressure demand or other positive pressure mode.
6. Accidental Release Measures
Ventilate area of leak or spill. Wear appropriate personal protective
equipment as specified in Section 8. Spills: Pick up and place
in a suitable container for reclamation or disposal, using a method
that does not generate dust.
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 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 positive-pressure,
air-supplied respirator. WARNING: Air-purifying respirators do
not protect workers in oxygen-deficient atmospheres.
Skin Protection:
Wear impervious protective clothing, including boots, gloves,
lab coat, apron or coveralls, as appropriate, to prevent skin
contact.
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.

of carbon dioxide. Thermal decomposition may also form potassium
oxide.

Acids, chlorine trifluoride, magnesium. An explosion occurred
after mixing sodium hydrosulfite, aluminum powder, potassium carbonate
and benzaldehyde.
