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. Circulatory collapse with clammy skin, weak and rapid
pulse, shallow respirations, and scanty urine may follow ingestion or skin contact. Circulatory shock
is often the immediate cause of death.
Skin Contact:
Corrosive. Symptoms of redness, pain, and severe burn can occur. Circulatory collapse with
clammy skin, weak and rapid pulse, shallow respirations, and scanty urine may follow skin contact
or ingestion. Circulatory shock is often the immediate cause of death.
Eye Contact:
Corrosive. Contact can cause blurred vision, redness, pain and severe tissue burns. Can cause
blindness.
Chronic Exposure:
Long-term exposure to mist or vapors may cause damage to teeth. Chronic exposure to mists
containing sulfuric acid is a cancer hazard.
Aggravation of Pre-existing Conditions:
Persons with pre-existing skin disorders or eye problems or impaired respiratory function may be
more susceptible to the effects of the substance.

4. First Aid Measures
Inhalation:
Remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen.
Call a physician immediately.
Ingestion:
DO NOT INDUCE VOMITING. Give large quantities of water. Never give anything by mouth to
an unconscious person. Call a physician 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. Excess acid on skin can be
neutralized with a 2% solution of bicarbonate of soda. Call a physician immediately.
Eye Contact:
Immediately flush eyes with gentle but large stream of water for at least 15 minutes, lifting lower and
upper eyelids occasionally. Call a physician immediately.
5. Fire Fighting Measures
Fire:
Concentrated material is a strong dehydrating agent. Reacts with organic materials and may cause
ignition of finely divided materials on contact.
Explosion:
Contact with most metals causes formation of flammable and explosive hydrogen gas.
Fire Extinguishing Media:
Dry chemical, foam or carbon dioxide. Do not use water on material. However, water spray may
be used to keep fire exposed containers cool.
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 this material. Stay away
from sealed containers.
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庐 or TEAM庐 '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, always add the
acid to water; never add water to the acid. 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:
For Sulfuric Acid:
- OSHA Permissible Exposure Limit (PEL) -
1 mg/m3 (TWA)
- ACGIH Threshold Limit Value (TLV) -
1 mg/m3(TWA), 3 mg/m3 (STEL), A2 - suspected human carcinogen for sulfuric acid contained in
strong inorganic acid mists.
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 and engineering controls are not feasible, a full facepiece respirator
with an acid gas cartridge and particulate filter (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 particulate 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. Where respirators are required, you must have a written program
covering the basic requirements in the OSHA respirator standard. These include training, fit testing,
medical approval, cleaning, maintenance, cartridge change schedules, etc. See 29CFR1910.134 for
details.
Skin Protection:
Wear impervious protective clothing, including boots, gloves, lab coat, apron or coveralls, as
appropriate, to prevent skin contact.
