Potential Health Effects
----------------------------------
Inhalation: Vapors can produce CNS depression, eye and upper respiratory tract irritation. Mist may be corrosive
to mucous membranes. Symptoms may include burning sensation, headache, dizziness, tremors, nausea and other
symptoms similar to ingestion.
Ingestion: Toxic. Corrosive. Symptoms parallel inhalation. May be fatal; May cause blindness if swallowed.
Central nervous system depression occurs, ranging from inebriation to anesthesia, narcosis, coma, respiratory
failure, and death in significant exposures. Corrosive to mucous membranes. Symptoms include headaches,
tremors, fatigue, hallucinations, distorted perceptions, and convulsions.
Skin Contact: Harmful if absorbed through skin. May cause defatting of skin and irritation with redness.
Eye Contact: Vapors irritate the eyes. Splashes cause burning and stinging sensation with watering of the eyes and
reflex closure of the lids.
Chronic Exposure: Chronic exposure may affect the central nervous system, liver, blood and reproductive system.
Examples of chronic effects include physical dependence, malnutrition, neurological effects (e.g., amnesia,
dementia, prolonged sleepiness). Chronic ingestion has been associated with cancers of the esophagus and liver.
Repeated or prolonged skin contact may result in drying of the skin and dermatitis. Combined exposure to ethanol
and certain other chemicals may result in increased toxic effects. Prolonged exposure may affect the kidneys.
Aggravation of Pre-existing Conditions: Persons with pre-existing skin disorders, eye problems, liver disease,
central nervous system disorders, 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.
Get medical attention.
Ingestion: Give 2-3 glasses of water to dilute. Do not induce vomiting. 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. Remove contaminated clothing
and shoes. Get medical attention. Wash clothing before reuse. Destroy contaminated shoes.
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
Flash point (TCC): No information available for mixture.
Autoignition temperature: No information available for mixture.
Flammable limits in air % by volume: LEL: 3.3 Listed values are for pure ethanol. Flammable Liquid and Vapor!
Explosion: Sealed containers may rupture when heated. Above the flash point, explosive vapor-air mixtures may be
formed. Vapor may explode if ignited in an enclosed area. Vapors can flow along surfaces to distant ignition source
and flash back.
REAGENTS, INC.--MSDS鈥擭ITAL ETCHANT PAGE 3
Fire Extinguishing Media: Most appropriate extinguishers are carbon dioxide and alcohol-resistant foam. Use
water in flooding quantities as fog. Water spray may be used to keep fire exposed containers cool. Do not allow
water runoff to enter sewers or waterways.
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. Contain
and recover liquid when possible. Use non-sparking tools and equipment. 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. Do not use combustible materials, such as saw dust. Do not flush to sewer! If a leak or spill has not
ignited, use water spray to disperse the vapors, to protect personnel attempting to stop leak, and to flush spills
away from exposures. 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
Protect against physical damage. Store in a cool, dry well-ventilated location, away from any area where the fire
hazard may be acute. Outside or detached storage is preferred. Separate from incompatibles. Containers should be
bonded and grounded for transfers to avoid static sparks. Storage and use areas should be No Smoking areas. Use
non-sparking type tools and equipment, including explosion proof ventilation. 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. Do Not attempt to clean empty containers since residue is difficult to remove. Do not
pressurize, cut, weld, braze, solder, drill, grind or expose such containers to heat, sparks, flame, static electricity or
other sources of ignition: they may explode and cause injury or death.
8. Exposure Controls/Personal Protection
Airborne Exposure Limits:
For Ethyl Alcohol: - OSHA Permissible Exposure Limit (PEL): 1,000 ppm (TWA)
- ACGIH Threshold Limit Value (TLV): 1,000 ppm (TWA), A4 (Not Classifiable as a Human Carcinogen)
For Methyl Alcohol:- OSHA Permissible Exposure Limit (PEL): 200 ppm (TWA)
- ACGIH Threshold Limit Value (TLV): 200 ppm (TWA), 250 ppm (STEL) skin
For Methyl Isobutyl Ketone: -OSHA Permissible Exposure Limit (PEL): 100 ppm (TLV) TWA 50 ppm
-ACGIH Threshold Limit Value (TLV STEL): 75 ppm
For Nitric Acid:-OSHA Permissible Exposure Limit (PEL):2 ppm (TWA), 4 ppm (STEL)
-ACGIH Threshold Limit Value (TLV):2 ppm (TWA); 4 ppm (STEL)
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, wear a supplied air, full-facepiece
respirator, airlined hood, or full-facepiece self-contained breathing apparatus.
Skin Protection: Wear impervious protective clothing, including boots, gloves, lab coat, apron or coveralls, as
appropriate, to prevent skin contact.
REAGENTS, INC.--MSDS鈥擭ITAL ETCHANT PAGE 4
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.
