Potential Health Effects
----------------------------------
Information on the human health effects from exposure to this substance is
limited.
Inhalation:
Corrosive. Extremely destructive to tissues of the mucous membranes and
upper respiratory tract. Symptoms may include burning sensation, coughing,
wheezing, laryngitis, shortness of breath, headache, nausea and vomiting.
Inhalation may be fatal as a result of spasm inflammation and edema of the
larynx and bronchi, chemical pneumonitis and pulmonary edema.
Ingestion:
Extremely destructive to tissues.
Skin Contact:
Extremely destructive to skin.
Eye Contact:
Extremely destructive to eyes.
Chronic Exposure:
No information found.
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. Call a physician.
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:
In case of contact, immediately flush skin with plenty of water for at
least 15 minutes while removing contaminated clothing and shoes. Wash
clothing before reuse. Thoroughly clean shoes before reuse. Get medical
attention immediately.
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.
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. Remove all sources of ignition. Wear
appropriate personal protective equipment as specified in Section 8.
Isolate hazard area. Keep unnecessary and unprotected personnel from
entering. Use water spray to dilute spill to a nonflammable mixture.
Contain and recover liquid when possible. Collect liquid in an appropriate
container or absorb with an inert material (e. g., vermiculite, dry sand,
earth), and place in a chemical waste container. Use non-sparking tools and
equipment. Do not use combustible materials, such as saw dust. Do not flush
to sewer!
J. T. Baker NEUTRASORB(tm) or TEAM(tm) 'Low Na+' acid neutralizers are
recommended for spills of this product.
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 (vapors, liquid); 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, a half-face respirator with an acid gas
cartridge 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 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. 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 a full face shield where splashing is
possible. Maintain eye wash fountain and quick-drench facilities in work
area.
