**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Flammable. Harmful by inhalation. Toxic to aquatic organisms, may
cause long-term adverse effects in the aquatic environment.
Potential Health Effects
Eye:
Contact produces irritation, tearing, and burning pain.
Skin:
Causes skin irritation. Prolonged and/or repeated contact may cause
defatting of the skin and dermatitis. Produces acneiform eruptions.
Ingestion:
May cause liver and kidney damage. May cause central nervous system
depression, characterized by excitement, followed by headache,
dizziness, drowsiness, and nausea. Advanced stages may cause
collapse, unconsciousness, coma and possible death due to respiratory
failure. May be harmful if swallowed. May cause hemolysis.
Inhalation:
Inhalation of high concentrations may cause central nervous system
effects characterized by nausea, headache, dizziness, unconsciousness
and coma. Causes respiratory tract irritation. May cause effects
similar to those described for ingestion. Exposure may cause bone
marrow changes. Exposure may cause blood abnormalities.
Chronic:
Chronic inhalation and ingestion may cause effects similar to those
of acute inhalation and ingestion. Repeated contact may result in
skin burns.
**** SECTION 4 - FIRST AID MEASURES ****
Eyes:
Immediately flush eyes with plenty of water for at least 15 minutes,
occasionally lifting the upper and lower eyelids. Get medical aid.
Skin:
Flush skin with plenty of water for at least 15 minutes while
removing contaminated clothing and shoes. Get medical aid if
irritation develops or persists. Wash clothing before reuse.
Ingestion:
Do not induce vomiting. If victim is conscious and alert, give 2-4
cupfuls of milk or water. Never give anything by mouth to an
unconscious person. Get medical aid immediately.
Inhalation:
Remove from exposure and move to fresh air immediately. If not
breathing, give artificial respiration. If breathing is difficult,
give oxygen. Get medical aid. Do NOT use mouth-to-mouth
resuscitation.
Notes to Physician:
**** SECTION 5 - FIRE FIGHTING MEASURES ****
General Information:
As in any fire, wear a self-contained breathing apparatus in
pressure-demand, MSHA/NIOSH (approved or equivalent), and full
protective gear. Vapors may form an explosive mixture with air.
Vapors can travel to a source of ignition and flash back. During a
fire, irritating and highly toxic gases may be generated by thermal
decomposition or combustion. Use water spray to keep fire-exposed
containers cool. Flammable liquid and vapor. Vapors may be heavier
than air. They can spread along the ground and collect in low or
confined areas. Containers may explode when heated.
Extinguishing Media:
Use water spray to cool fire-exposed containers. Water may be
ineffective. Do NOT use straight streams of water. For small fires,
use dry chemical, carbon dioxide, water spray or regular foam. Cool
containers with flooding quantities of water until well after fire
is out. For large fires, use water spray, fog or regular foam.
**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Absorb spill with inert material (e.g. vermiculite, sand or earth),
then place in suitable container. Avoid runoff into storm sewers and
ditches which lead to waterways. Clean up spills immediately,
observing precautions in the Protective Equipment section. Remove all
sources of ignition. A vapor suppressing foam may be used to reduce
vapors. Water spray may reduce vapor but may not prevent ignition in
closed spaces.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Use with adequate ventilation.
Ground and bond containers when transferring material. Avoid contact
with eyes, skin, and clothing. Empty containers retain product
residue, (liquid and/or vapor), and can be dangerous. Keep container
tightly closed. Keep away from heat, sparks and flame. Avoid
ingestion and inhalation. Do not pressurize, cut, weld, braze,
solder, drill, grind, or expose empty containers to heat, sparks or
open flames.
Storage:
Keep away from heat and flame. Keep away from sources of ignition.
Store in a tightly closed container. Keep from contact with oxidizing
materials. Store in a cool, dry, well-ventilated area away from
incompatible substances.
**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****
Engineering Controls:
Use process enclosure, local exhaust ventilation, or other
engineering controls to control airborne levels below recommended
exposure limits. Facilities storing or utilizing this material should
be equipped with an eyewash facility and a safety shower.
