3. Hazards Identification
Emergency Overview
--------------------------
POISON! DANGER! CORROSIVE. LIQUID AND MIST CAUSE SEVERE BURNS TO ALL BODY
TISSUE. MAY BE FATAL IF SWALLOWED. HARMFUL IF INHALED. INHALATION MAY CAUSE
LUNG DAMAGE. WATER REACTIVE. STRONG OXIDIZER. CONTACT WITH OTHER
MATERIAL MAY CAUSE FIRE OR EXPLOSION. STRONG INORGANIC ACID MISTS
CONTAINING SULFURIC ACID CAN CAUSE CANCER. Risk of cancer depends on duration and level
of exposure.
Potential Health Effects
----------------------------------
Inhalation:
Corrosive! Fuming sulfuric acid vapors, fumes and mists can burn all surfaces of the respiratory tract chemically
as well as by heat of reaction with water. Coughing, choking and breathing difficulty can be immediate
symptoms; tissue destruction, lung edema, etc. can follow severe exposure.
Ingestion:
Corrosive! Causes very severe often fatal burns in the mouth and esophagus due to tissue destruction and heat.
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. Gastrointestinal upset and
associated secondary symptoms may accompany the ingestion of small amounts.
Skin Contact:
Corrosive! Can destroy skin layers and subsurface tissue on contact. Produces deep, slow healing burns.
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! Vapors, fumes and mists can cause severe irritation. Can destroy eye tissue on contact. A painful
burning sensation and tearing will be the immediate symptoms, scarring or loss of sight are expected.
Chronic Exposure:
Damage to tooth enamel and injury to the respiratory tract may follow prolonged exposure to vapors. 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. Speed in diluting and rinsing with water is extremely
important.
5. Fire Fighting Measures
Fire:
Not combustible, but substance is a strong oxidizer and its heat of reaction with reducing agents or combustibles
may cause ignition.
Explosion:
Contact with most metals causes formation of flammable and explosive hydrogen gas. A violent exothermic
reaction occurs with water. Sufficient heat may be produced to ignite combustible materials.
Fire Extinguishing Media:
Dry chemical, foam or carbon dioxide. DO NOT ADD water or other liquid to the acid.
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. Water spray may be
used to extinguish surrounding fire and cool exposed containers. Water spray will also reduce fume and irritant
gases.
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.
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:
For Sulfuric Acid:
- OSHA Permissible Exposure Limit (PEL) -
1 mg/m3 (TWA)
- ACGIH Threshold Limit Value (TLV) -
0.2 mg/m3(T) (TWA) for sulfuric acid - A2 Suspected Human Carcinogen for sulfuric acid contained in strong
inorganic 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):
For sulfuric acid: 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.
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.
