**** SECTION 3 - HAZARDS IDENTIFICATION ****

EMERGENCY OVERVIEW
Toxic if swallowed. Irritating to eyes and skin.Light
sensitive.Moisture sensitive.

Potential Health Effects
Eye:
Causes eye irritation.
Skin:
Causes skin irritation. Harmful if absorbed through the skin.
Ingestion:
May be fatal if swallowed. May cause gastrointestinal irritation
with nausea, vomiting and diarrhea. May cause central nervous system
effects and/or neurological effects.
Inhalation:
Harmful if inhaled. Causes respiratory tract irritation.
Chronic:
Exposure limits have been recommended for organotin compounds to
minimize the potential for adverse effects on immune function and the
CNS.

**** SECTION 4 - FIRST AID MEASURES ****

Eyes:
Flush eyes with plenty of water for at least 15 minutes,
occasionally lifting the upper and lower eyelids. Immediately flush
eyes with plenty of water for at least 15 minutes, occasionally
lifting the upper and lower eyelids. Get medical aid. Get medical aid
immediately.
Skin:
Get medical aid. Flush skin with plenty of water for at least 15
minutes while removing contaminated clothing and shoes. Wash clothing
before reuse. Remove contaminated clothing and shoes.
Ingestion:
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. 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 not breathing, give artificial respiration. If
breathing is difficult, give oxygen. Get medical aid.
Notes to Physician:
Treat symptomatically and supportively.

**** 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. Use water
spray to keep fire-exposed containers cool. Vapors may be heavier
than air. They can spread along the ground and collect in low or
confined areas. May polymerize explosively when involved in a fire.
Contact with metals may evolve flammable hydrogen gas. Containers may
explode when heated. Combustible material; may burn but does not
ignite readily.
Extinguishing Media:
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.
Cool containers with flooding quantities of water until well after
fire is out.

**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****

General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
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. Absorb spill using
an absorbent, non-combustible material such as earth, sand, or
vermiculite. Do not use combustible materials such as sawdust.
Provide ventilation. Do not get water inside containers.

**** SECTION 7 - HANDLING and STORAGE ****

Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Avoid contact with eyes, skin, and clothing. Keep
container tightly closed. Avoid ingestion and inhalation. Use with
adequate ventilation. Store protected from light. Do not allow
contact with water. Keep from contact with moist air and steam.
Storage:
Store in a tightly closed container. Store in a cool, dry,
well-ventilated area away from incompatible substances. Do not store
in metal containers. Store protected from moisture. Store protected
from light.

**** 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 general or
local exhaust ventilation to keep airborne concentrations below the
permissible exposure limits.
