Potential Health Effects
----------------------------------

Inhalation:
Inhalation produces damaging effects on the
mucous membranes and upper respiratory tract. Symptoms may include irritation
of the nose and throat, and labored breathing. May cause lung edema, a medical
emergency.
Ingestion:
Corrosive. Swallowing can cause severe
burns of the mouth, throat, and stomach, leading to death. Can cause sore
throat, vomiting, diarrhea.
Skin Contact:
Corrosive. Symptoms
of redness, pain, and severe burn can occur.
Eye Contact:

Acidic irritant. Pain, tearing and redness can occur. Crystalline dust may
also be abrasive. Solutions are acidic and splashes may cause eye damage.

Chronic Exposure:
Lung irritation, tracheal bronchitis,
persistent coughing, and corrosion of teeth are possible effects from long
term exposure to dust, mist or fumes from wet or moist sodium bisulfate.

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 while
removing contaminated clothing and shoes. Get medical attention immediately.
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.

Fire Extinguishing Media:
Use any means suitable for
extinguishing surrounding fire. Water may be used to cool containers and to
knock down vapors in a fire situation. Do not use water on material itself or
allow water to get inside container.
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. Keep unnecessary and unprotected
people away from area of 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):
If the exposure limit is
exceeded and engineering controls are not feasible, a half-face respirator
with an acid gas cartridge and particulate (NIOSH type N95 or better) filter
may be worn for up to ten times the exposure limit or the maximum use
concentration specified by the appropriate regulatory agency or respirator
supplier, whichever is lowest. A full-face piece respirator with an acid gas
cartridge and particulate (NIOSH type N100) filter may be worn up to 50 times
the exposure limit, or the maximum use concentration specified by the
appropriate regulatory agency, or respirator supplier, whichever is lowest. 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-facepiece 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.

13. Disposal Considerations

Whatever cannot be saved for recovery or recycling should be
managed in an appropriate and approved waste facility. Although not a listed
RCRA hazardous waste, this material may exhibit one or more characteristics of
a hazardous waste and require appropriate analysis to determine specific
disposal requirements. Processing, use or contamination of this product may
change the waste management options. State and local disposal regulations may
differ from federal disposal regulations. Dispose of container and unused
contents in accordance with federal, state and local requirements.
