**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Harmful in contact with skin. Toxic if swallowed. Irritating to eyes
and skin. Toxic : danger of serious damage to health by prolonged
exposure through inhalation and if swallowed. Very toxic to aquatic
organisms, may cause long-term adverse effects in the aquatic
environment.The toxicological properties of this material have not
been fully investigated.Moisture sensitive.
Potential Health Effects
Eye:
Causes eye irritation.
Skin:
Causes skin irritation.
Ingestion:
May cause irritation of the digestive tract. May cause liver and
kidney damage. May cause cardiac disturbances. The toxicological
properties of this substance have not been fully investigated. May
cause central nervous system effects.
Inhalation:
May cause respiratory tract irritation. May cause liver and kidney
damage. The toxicological properties of this substance have not been
fully investigated. Central nervous system effects may include
confusion, ataxia (failure of muscular coordination), vertigo,
tinnitus, weakness, disorientation, lethargy, drowsiness, and
finally coma. May cause cardiac abnormalities.
Chronic:
Chronic inhalation and ingestion may cause effects similar to those
of acute inhalation and ingestion. May cause liver and kidney
damage. The critical effect of tributyltin compounds in rats is on
the immune system (ACGIH 7th Edition Documentation of the TLVs).
**** 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
immediately.
Skin:
Get medical aid immediately. Immediately flush skin with plenty of
water for at least 15 minutes while removing contaminated clothing
and shoes. Wash clothing before reuse.
Ingestion:
Never give anything by mouth to an unconscious person. Get medical
aid immediately. Do NOT induce vomiting. If conscious and alert,
rinse mouth and drink 2-4 cupfuls of milk or water.
Inhalation:
Get medical aid immediately. Remove from exposure and move to fresh
air immediately. If breathing is difficult, give oxygen. Do NOT use
mouth-to-mouth resuscitation. If breathing has ceased apply
artificial respiration using oxygen and a suitable mechanical device
such as a bag and a mask.
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. During a fire, irritating and highly toxic gases
may be generated by thermal decomposition or combustion. Will burn
if involved in a fire. Vapors may be heavier than air. They can
spread along the ground and collect in low or confined areas. Vapors
may form an explosive mixture with air. Containers may explode when
heated. Combustible material; may burn but does not ignite readily.
Runoff from fire control or dilution water may cause pollution.
Extinguishing Media:
Use water spray to cool fire-exposed containers. Do NOT get water
inside containers. For small fires, use dry chemical, carbon
dioxide, or water spray. For large fires, use dry chemical, carbon
dioxide, alcohol-resistant foam, or water spray.
**** 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. Provide
ventilation. Do not get water inside containers.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Do not breathe dust, vapor, mist, or
gas. Do not get in eyes, on skin, or on clothing. Keep container
tightly closed. Avoid ingestion and inhalation. Do not allow contact
with water. Use only in a chemical fume hood. Keep from contact with
moist air and steam.
Storage:
Keep away from sources of ignition. Store in a tightly closed
container. Keep under a nitrogen blanket. Store in a cool, dry,
well-ventilated area away from incompatible substances. Store
protected from moisture.
**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****
Engineering Controls:
Facilities storing or utilizing this material should be equipped
with an eyewash facility and a safety shower. Use adequate
ventilation to keep airborne concentrations low.
