3. HAZARDS IDENTIFICATION
|
EMERGENCY OVERVIEW
* Clear liquid. Harmful if inhaled. Toxic fumes are released in
fire situations. *
POTENTIAL HEALTH EFFECTS
(See Section 11 for toxicological data.)
EYE:
Essentially nonirritating to eyes..
SKIN: Prolonged contact is essentially nonirritating to skin.
Material may stick to skin causing irritation upon removal. Skin
contact may result in allergic skin reactions or respiratory sensitization
but is not expected to result in absorption of amounts sufficient
to cause other adverse effects. May stain skin.
INGESTION: Single dose oral toxicity is considered to be
low. Ingestion may cause gastrointestinal irritation. Small amounts
swallowed incidental to normal handling operations are not likely
to cause injury; swallowing amounts larger than that may cause injury.
INHALATION: At room temperature, vapors are minimal due to
low vapor pressure. However, certain operations may generate vapor
or aerosol concentrations sufficient to cause irritation or other
adverse effects. Such operations include those in which the material
is heated, sprayed or otherwise mechanically dispersed such as drumming,
venting or pumping. Excessive exposure may cause irritation of eyes,
upper respiratory tract, and lungs. May cause respiratory sensitization
in susceptible individuals. MDI concentrations below the exposure
guidelines may cause allergic respiratory reactions in individuals
already sensitized. Symptoms may include coughing, difficult breathing
and a feeling of tightness in the chest. Effects may be delayed.
Impaired lung function (decreased ventilatory capacity) has been
associated with overexposure to isocyanates.
CHRONIC EFFECTS
SYSTEMIC (OTHER TARGET ORGAN) EFFECTS: Tissue injury in the
upper respiratory tract and lungs has been observed in laboratory
animals after repeated excessive exposures to MDI/polymeric MDI
aerosol 5.
CANCER INFORMATION: Lung tumors have been observed in laboratory
animals exposed to aerosol droplets of MDI/Polymeric MDI (6 mg/m3)
for their lifetime. Tumors occurred concurrently with respiratory
irritation and lung injury. Current exposure guidelines are expected
to protect against these effects. TERATOLOGY (BIRTH DEFECTS):
In laboratory animals, MDI/polymeric MDI did not produce birth defects;
other fetal effects occurred only at high doses which were toxic
to the mother.
EYES:
Flush eyes with plenty of water. Materials containing MDI may react
with the moisture of the eye forming a thick material which may
be difficult to wash from the eye.
SKIN: Wash off in flowing water or shower.
INGESTION: If swallowed, seek medical attention. Do not induce
vomiting unless directed to do so by medical personnel.
INHALATION: Remove to fresh air. If not breathing, give artificial
respiration. If breathing is difficult, oxygen should be administered
by qualified personnel. Call a physician or transport to a medical
facility.
NOTE TO PHYSICIAN: Supportive care. Treatment based on judgment
of the physician in response to reactions of the patient. No specific
antidote. The manifestations of respiratory symptoms, including
pulmonary edema, resulting from acute exposure may be delayed. May
cause respiratory sensitization.

5. FIRE FIGHTING
MEASURES
|
FLAMMABLE PROPERTIES
FLASH POINT: >360F, >182C
METHOD USED: PMCC ASTM D93
AUTOIGNITION TEMPERATURE: Not determined.
FLAMMABILITY LIMITS
LFL: Not determined
UFL: Not determined
HAZARDOUS COMBUSTION PRODUCTS: Isocyanate vapor and mist,
carbon dioxide, carbon monoxide, nitrogen oxides and traces of hydrogen
cyanide.
OTHER FLAMMABILITY INFORMATION: Toxic fumes are released
in fire situations.
EXTINGUISHING MEDIA: Carbon dioxide, dry chemical, or foam.
For large scale fires, alcohol resistant foams are preferred if
available. General purpose synthetic foams or protein foams may
function, but much less effectively. Water may be used as a blanket
for fire extinguishment. If water is used, it should be used in
very large quantity. The reaction between water and isocyanate may
be vigorous. If possible, contain fire run off water.
FIRE FIGHTING INSTRUCTIONS: Down-wind personnel must be evacuated.
Do not reseal contaminated containers. A chemical reaction generating
C02 gas pressure may occur resulting in rupture of the container.
Dense smoke emitted when burned without sufficient oxygen. When
using water spray, boil over may occur when the product temperature
reaches the boiling point of water and the reaction forming C02
will accelerate (tank type scenarios, not spills).
PROTECTIVE EQUIPMENT FOR FIRE FIGHTERS: People who are fighting
isocyanate fires must be protected against nitrogen oxide fumes
and isocyanate vapors by wearing positive pressure self-contained
breathing apparatus and full protective clothing.
|
6. ACCIDENTAL
RELEASE MEASURES (See Section 15 for Regulatory Information)
|
PROTECT PEOPLE:
Evacuate and ventilate spill area, wear full protective equipment
including respiratory equipment during clean up.
PROTECT THE ENVIRONMENT:
Major spill: Call Dow Chemical U.S.A., (409) 238-2112.
If transportation spill involved call CHEMTREC, (800) 424-9300.
If temporary control of isocyanate vapor is required, a blanket
of protein foam (available at most fire departments) may be placed
over the spill. Large quantities may be pumped into closed but not
sealed containers for disposal. Dike spill to prevent entry into
sewers, storm drains, surface waters or soil.
Minor spill: Absorb the isocyanate with sawdust or other
absorbent and shovel into open top containers. Do not make pressure
tight. Transport to a well-ventilated area (outside) and treat with
neutralizing solution consisting of a mixture of water and 3-8%
concentrated ammonium hydroxide or 5-lO% sodium carbonate. Add about
10 parts of neutralizer per part of isocyanate with mixing. Allow
to stand for 48 hours letting evolved carbon dioxide to escape.
CLEANUP: Decontaminate floor using water/ammonia solution
with l-2% added detergent letting stand over affected area for at
least 10 minutes. Cover mops and brooms used for this with plastic
and dispose properly (often by incineration).
HANDLING:
In accordance with good manufacturing practices, good general ventilation
of the processing area is recommended. Spills of organic liquids
on hot fibrous insulation may result in spontaneous combustion and
lead to fire.
The reaction of polyols and isocyanates generate heat. Contact of
the reacting materials with skin or eyes can cause severe burns
and may be difficult to remove from the affected areas. In addition,
such contact increases the risk of exposure to isocyanate vapors.
Seek immediate medical assistance in case of skin or eye contact.
STORAGE: Store indoors at 75-105F in original, unopened containers.
Protect from atmospheric moisture. Replace outage with inert dry
gas nitrogen.
|
8. EXPOSURE CONTROLS/PERSONAL
PROTECTION
|
ENGINEERING CONTROLS:
Provide general and/or local exhaust ventilation to control airborne
levels below the exposure guidelines.
PERSONAL PROTECTIVE EQUIPMENT EYE/FACE PROTECTION: Use safety
glasses.
SKIN PROTECTION: Use protective clothing impervious to this
material. Selection of specific items such as faceshield, gloves,
boots, apron, or full-body suit will depend on operation. Remove
contaminated clothing immediately, wash with soap and water, and
launder clothing before reuse.
RESPIRATORY PROTECTION: Atmospheric levels should be maintained
below the exposure guideline. When respiratory protection is required,
use an approved air-purifying or positive-pressure supplied-air
respirator depending on the potential airborne
EXPOSURE GUIDELINE(S): Methylene bisphenyl isocyanate
(MDI): ACGIH TLV is 0.005 ppm TWA and OSHA PEL is 0.02 ppm Ceiling.
PELs are in accord with
those recommended by OSHA, the 1989 revision of PELs.

10. STABILITY
AND REACTIVITY
|
CHEMICAL STABILITY:
Maintain material at a temperature in the range of 75-lO5F (24-4lC)
CONDITIONS TO AVOID: Avoid prolonged heating over 160F (71C)
or storage below 75F (24C).
Stable when stored under normal conditions.
Decomposition begins at 350F (177C).
INCOMPATIBILITY WITH OTHER MATERIALS: Water, acids, bases1
alcohols, metal compounds, and surface active materials. Avoid water
as it reacts to form heat, C02 and insoluble urea. The combined
effect of the C02 and heat can produce enough pressure to rupture
a closed container. The reaction with water is slow at temperatures
less than 120F (49C) , but accelerated at higher temperatures and
in the presence of the above mentioned materials.
Some reactions are violent.
HAZARDOUS DECOMPOSITION PRODUCTS: Excessive heating can produce
isocyanate vapor, mist and other hazardous organic compounds.
HAZARDOUS POLYMERIZATION: May occur with incompatible reactants,
especially strong bases, water or temperatures over 320F (16oC).
