Potential Health Effects
----------------------------------
Inhalation:
Corrosive! Inhalation of vapors can cause coughing, choking, inflammation
of the nose, throat, and upper respiratory tract, and in severe cases,
pulmonary edema, circulatory failure, and death.
Ingestion:
Corrosive! Swallowing hydrochloric acid can cause immediate pain and burns
of the mouth, throat, esophagus and gastrointestinal tract. May cause
nausea, vomiting, and diarrhea. Swallowing may be fatal.
Skin Contact:
Corrosive! Can cause redness, pain, and severe skin burns. Concentrated
solutions cause deep ulcers and discolor skin.
Eye Contact:
Corrosive! Vapors are irritating and may cause damage to the eyes. Contact
may cause severe burns and permanent eye damage.
Chronic Exposure:
Long-term exposure to concentrated vapors may cause erosion of teeth. Long
term exposures seldom occur due to the corrosive properties of the acid.
Aggravation of Pre-existing Conditions:
Persons with pre-existing skin disorders or eye disease may be more
susceptible to the effects of this substance.
4. First Aid Measures
Inhalation:
Remove to fresh air. If not breathing, give artificial respiration. If
breathing is difficult, give oxygen. Get medical attention immediately.
Ingestion:
DO NOT INDUCE VOMITING! Give large quantities of water or milk if
available. 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:
Extreme heat or contact with metals can release flammable hydrogen gas.
Explosion:
Not considered to be an explosion hazard.
Fire Extinguishing Media:
If involved in a fire, use water spray. Neutralize with soda ash or slaked
lime.
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. Structural firefighter's
protective clothing is ineffective for fires involving hydrochloric acid.
Stay away from ends of tanks. Cool tanks with water spray until well after
fire is out.
6. Accidental Release Measures
Ventilate area of leak or spill. Wear appropriate personal protective
equipment as specified in Section 8. Isolate hazard area. Keep unnecessary
and unprotected personnel from entering. Contain and recover liquid when
possible. Neutralize with alkaline material (soda ash, lime), then absorb
with an inert material (e. g., vermiculite, dry sand, earth), and place in
a chemical waste container. Do not use combustible materials, such as saw
dust. Do not flush to sewer! US Regulations (CERCLA) require reporting
spills and releases to soil, water and air in excess of reportable
quantities. The toll free number for the US Coast Guard National Response
Center is (800) 424-8802.
J. T. Baker NEUTRASORB(R) or TEAM(R) 'Low Na+' acid neutralizers
are recommended for spills of this product.
7. Handling and Storage
Store in a cool, dry, ventilated storage area with acid resistant floors
and good drainage. Protect from physical damage. Keep out of direct
sunlight and away from heat, water, and incompatible materials. Do not wash
out container and use it for other purposes. When diluting, the acid should
always be added slowly to water and in small amounts. Never use hot water
and never add water to the acid. Water added to acid can cause uncontrolled
boiling and splashing. When opening metal containers, use non-sparking
tools because of the possibility of hydrogen gas being present. 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:
-OSHA Permissible Exposure Limit (PEL):
5 ppm Ceiling
-ACGIH Threshold Limit Value (TLV):
5 ppm Ceiling
Ventilation System:
A system of local and/or general exhaust is recommended to keep employee
exposures below the Airborne Exposure Limits. 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 full facepiece 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:
Rubber or neoprene gloves and additional protection including impervious
boots, apron, or coveralls, as needed in areas of unusual exposure 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.
