Potential Health Effects
----------------------------------
Inhalation:
Severe irritation or burns of respiratory system, headache, nausea,
vomiting, dizziness, loss of balance and coordination, confusion,
unconsciousness, coma, respiratory failure and death. Repeated excessive
exposures may cause blood disorders such as anemia and leukemia. Liver and
kidney effects or damage. central nervous system depression.
Ingestion:
Headache, nausea, vomiting, dizziness, gastrointestinal irritation, blurred
vision, low blood pressure, Harmful or fatal if swallowed.
Skin Contact:
Irritation, prolonged contact may cause dermatitis, May be absorbed through
the skin with possible systemic effects.
Eye Contact:
Irritation, may cause temporary corneal damage.
Chronic Exposure:
Damage to blood forming tissue.
Aggravation of Pre-existing Conditions:
Skin disorders, kidney, liver, or blood disorders, eye disorders, nerve
system disorders, respiratory system disease.
4. First Aid Measures
Inhalation:
If inhaled, remove to fresh air. If not breathing, give artificial
respiration. If breathing is difficult, give oxygen.
Ingestion:
CALL A PHYSICIAN. DO NOT INDUCE VOMITING! Do not give liquids! Small
amounts which accidentally enter mouth should be rinsed out until taste of
it is gone.
Skin Contact:
Wash with soap and water until no odor remains. If redness or swelling
develops, Immediately remove soaked clothing wash clothing before reuse.
Destroy contaminated shoes.
Eye Contact:
Flush with water for at least 15 minutes.
Note to Physician:
Pulmonary aspiration hazard if swallowed and/or vomiting occurs - can enter
lungs and cause damage.
5. Fire Fighting Measures
Fire:
Flash point: -11C (12F) CC
Autoignition temperature: 498C (928F)
Flammable limits in air % by volume:
lel: 1.3; uel: 8.0
Explosion:
Vapors may flow along surfaces to distant ignition sources and flash back.
Closed containers exposed to heat may explode. Contact with strong
oxidizers may cause fire. Vapor forms explosive mixture with air. Sensitive
to static discharge.
Fire Extinguishing Media:
Use alcohol foam, dry chemical or carbon dioxide. (Water may be
ineffective.)
Special Information:
Firefighters should wear proper protective equipment and self-contained
breathing apparatus with full facepiece operated in positive pressure mode.
Move containers from fire area if it can be done without risk. Use water
to keep fire-exposed containers cool.
6. Accidental Release Measures
7. Handling and Storage
Bond and ground containers when transferring liquid. Never siphon by mouth.
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):
1 ppm (TWA) PEL (Ceiling) = 25 ppm.
-ACGIH Threshold Limit Value (TLV):
10 ppm (TWA)
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 conditions of use where exposure to the substance is apparent, consult
an industrial hygienist. 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:
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.
