3. Hazards Identification
Emergency Overview
--------------------------
DANGER! MAY BE FATAL IF SWALLOWED, INHALED OR ABSORBED THROUGH
SKIN. CAUSES IRRITATION TO SKIN, EYES AND RESPIRATORY TRACT.
COMBUSTIBLE LIQUID AND VAPOR. AFFECTS BLOOD, KIDNEYS, LIVER,
CARDIOVASCULAR SYSTEM.
-----------------------------------------------------------------------------------------------------------
Potential Health Effects
----------------------------------
Inhalation:
May be fatal if excessively inhaled. Inhalation of vapors may cause systemic poisoning, symptom
may parallel those from ingestion exposure.
Ingestion:
May be fatal if excessively ingested. Can cause methemoglobinemia. May cause bluish skin,
headache, nausea, vomiting, and dry throat. Prominent central nervous system depression can occur,
with confusion, ataxia, vertigo, tinnitus, weakness, disorientation, lethargy, drowsiness, convulsions,
and coma. Death may occur from cardiovascular collapse. May cause kidney and liver damage and
blood disorders.
Skin Contact:
May cause irritation, redness, and pain. Readily absorbed through the skin. Symptoms may parallel
those from ingestion exposure.
Eye Contact:
May cause irritation, redness, pain, and corneal damage.
Chronic Exposure:
Repeated or prolonged exposure through any route of exposure may cause decreased appetite, with
anemia, weight loss, nervous system effects, and kidney, liver, and bone marrow damage.
Aggravation of Pre-existing Conditions:
Persons with impaired kidney, liver, or cardiovascular function or pre-existing blood disorders may
be more susceptible to the effects of this material.
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:
Induce vomiting immediately as directed by medical personnel. 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 while removing contaminated
clothing and shoes. Get medical attention immediately. Wash clothing before reuse. Thoroughly
clean shoes before reuse.
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:
Flash point: 63C (145F) CC
Autoignition temperature: 371C (700F)
Flammable limits in air % by volume:
lel: 1.0; uel: 7.0
Combustible Liquid and Vapor! Contact with strong oxidizers may cause fire.
Explosion:
Above flash point, vapor-air mixtures are explosive within flammable limits noted above.
Fire Extinguishing Media:
Water spray, dry chemical, alcohol foam, or carbon dioxide. 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. Fight
fire from maximum distance.
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! 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. 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.
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. 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:
-OSHA Permissible Exposure Limit (PEL):
5 ppm (TWA)
-ACGIH Threshold Limit Value (TLV):
5 ppm (TWA), 10 ppm (STEL) skin
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 half-face organic vapor
respirator 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 organic vapor respirator 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-face piece
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.
