EMERGENCY OVERVIEW
Appearance: white to beige powder.
Danger! Causes severe eye irritation and possible
eye injury. Harmful if swallowed, inhaled, or absorbed through the
skin. Causes skin and respiratory tract irritation. Possible risk of
harm to the unborn child. Severe marine pollutant. Moisture
sensitive.
Target Organs: Central nervous system,
respiratory system, eyes, immune system, reproductive system, skin.
Potential Health Effects
Eye:
Causes severe eye irritation and possible injury.
One instance of eye injury is reported in a worker who accidentally
splashed the liquid in his face and eyes. Despite immediate washing
with water, lacrimation and conjunctival hyperemia appeared within
minutes and persisted for four days. At the end of a week the skin
was still erythematous, but the eyes appeared normal. (Witco)
Skin:
Causes severe skin irritation. May be absorbed through the skin in
harmful amounts.
Ingestion:
Harmful if swallowed. May cause severe gastrointestinal tract
irritation with nausea, vomiting and possible burns.
Inhalation:
Harmful if inhaled. Causes respiratory tract irritation.
Chronic:
This substance has caused adverse reproductive and fetal effects in
laboratory animals. 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:
In case of contact, immediately flush eyes with plenty of water for a
t least 15 minutes. Get medical aid immediately.
Skin:
In case of contact, immediately flush skin with plenty of water.
Remove contaminated clothing and shoes. Get medical aid. Wash
clothing before reuse.
Ingestion:
If swallowed, do NOT induce vomiting. Get medical aid immediately.
If victim is fully conscious, give a cupful of water. Never give
anything by mouth to an unconscious person.
Inhalation:
If inhaled, remove to fresh air. 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.
Extinguishing Media:
Use water spray, dry chemical, carbon dioxide, or appropriate foam.
Solid streams of water or high volume water jet may spread fire.

NFPA Rating:
(estimated) Health: 3; Flammability: 1; Instability: 0
|
Section 6 - Accidental Release Measures
|
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Clean up spills immediately, observing precautions in the Protective
Equipment section. Sweep up, then place into a suitable container for
disposal. Avoid generating dusty conditions. Provide ventilation. Do
not let this chemical enter the environment.
|
Section 7 - Handling and Storage
|
Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Minimize dust generation and accumulation. Do not
breathe dust, mist, or vapor. Keep container tightly closed. Use
only with adequate ventilation. Do not get in eyes. Avoid contact
with skin and clothing.
Storage:
Keep container closed when not in use. Store in a cool, dry,
well-ventilated area away from incompatible substances. Store
protected from moisture. Store protected from heat and direct
sunlight.
|
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.

intubation with dibutyltin dichloride at doses of 10 or 15
mg/kg on day 7 and 8 of pregnancy. A significantly and
markedly increased incidence of fetuses with malformations

No data available.
Environmental:
Terrestrial: May adsorb to soil and biodegrade. Significant
adsorption to soil may limit leaching. Aquatic: If dibutyltin
dichloride is released to water, it will behave like a simple protic
acid due to the resulting formation of hydronium ion and either
dibutyltin dihydroxide or other dibutyltin-hydroxide species.
Atmospheric: May be present in both the vapor and particulate
phases. The compound may be susceptible to direct photolysis and may
be susceptible to the gas-phase reaction with photochemically
produced hydroxyl radicals.
