III. Hazards Identification
A. Emergency Overview:
Physical Appearance and Odor:
-1-
Material Safety Data Sheet
Product: Syntho-Glass
Fiberglass cloth, coated with viscous resin with no odor
B. Potential Health Effects:
Acute Eye:
Liquid, aerosols or vapor are irritating and can cause tearing, reddening and swelling. If left
untreated, corneal damage can occur and injury is slow to heal. Damage, however is usually
reversible.
Acute Skin:
Isocyanates react with skin protein and moisture and can cause irritation which may include the
following symptoms: reddening, swelling, rash, scaling or blistering. Cured material is difficult to
remove.
Acute Inhalation:
Although MDI is low volatility, an inhalation hazard can exist from MDI aerosols or vapors formed
during heating, foaming or spraying. Can irritate mucous membranes, cause runny nose, sore
throat, coughing, and other symptoms.
Acute ingestion:
Irritation and corrosive action can occur in the mouth, stomach tissue and digestive tract.
Symptoms can include: sore throat, abdominal pain, nausea, vomiting and diarrhea.
Chronic effects:
Prolonged skin contact can cause reddening, swelling, rash, scaling or blistering and in some
cases, skin sensitization. Individuals who have skin sensitization can develop these symptoms
from contact with liquid or vapor. Animal tests have indicated that respiratory sensitization can
result from skin contact with MDI. These data reinforce the need to prevent direct skin contact
with MDI.
Medical Conditions Aggravated by Exposure:
Asthma, other respiratory disorders (bronchitis, emphysema, bronchial hyper reactivity), skin
allergies, eczema.
IV. First Aid Measures
First Aid Measures for Accidental:
Eye Exposure:
Flush with copious amount of water. Preferably lukewarm, for at least 15 minutes, holding
eyelids open at all times. Refer individual to a physician or ophthalmologist for immediate follow
up.
Skin Exposure:
-2-
Material Safety Data Sheet
Product: Syntho-Glass
Remove contaminated clothing. Wash affected skin thoroughly with soap and water. Wash
contaminated clothing thoroughly before reuse. For severe exposures, get under safety shower
after removing clothing, then get medical attention. For lesser exposures, seek medical attention
if irritation develops or persists after area is washed.
Inhalation:
Move to an area free from risk of further exposure. Administer oxygen or artificial respiration as
needed. Obtain medical attention. Asthmatic 璽ype symptoms may develop and may be
immediate or delayed up to several hours. Consult physician should this development occur.
Ingestion:
Do not induce vomiting. Give one to two cups of milk or water to drink. Do not give anything by
mouth to an unconscious person, consult a physician.
Notes to Physician:
Eyes: stain for evidence of corneal injury. If cornea is burned, instill antibiotic steroid preparation
frequently. Workplace vapors have produced reversible corneal epithelial edema impairing vision
Skin: This compound is a known skin sensitizer. Treat symptomatically for contact dermatitis or
thermal burns, if burned treat as a thermal burn.
Ingestion: Treat symptomatically. There is no specific antidote. Inducing vomiting is
contraindicated because of the irritating nature of this compound.
Respiratory: This compound is a known pulmonary sensitizer. Treatment is essentially
symptomatic. Remove exposed individual to any isocyanate.
V. Fire Fighting Measures
Fire Hazard Data:
Flash Point: 370癋
Method Used: Pensky-Martens Closed Cup
Flammability Limits (vol/vol%): Lower: N/A Upper: N/A
Extinguishing Media:
Carbon Dioxide, foam, dry chemical. Water spray for large fires.
Special Fire Fighting Procedures:
Full emergency equipment with self-contained breathing apparatus and full protective clothing
should be worn by firefighters. During a fire, MDI vapors and other irritating, highly toxic gases
may be generated by thermal decomposition or combustion. At temperatures greater than 400?br>
F, polymeric MDI can polymerize and decompose which can cause pressure build-up in closed
containers. Explosive rupture is possible. Therefore, use cold water to cool fire-exposed
containers.

Hazardous Decomposition Materials (Under Fire Conditions):
Combustion produces carbon monoxide, oxides of nitrogen, and traces of HCN, MDI vapors or
aerosols.
VI. Accidental Release Measures
Cleanup and Disposal of Spill:
Normal housekeeping practices. Pick up and contain any spilled material.
Dispose of materials according to the applicable Federal, State, or local regulations.
VII. Handling and Storage
Handling:
No special procedures are necessary when handling this product.

Product: Syntho-Glass
Eye / Face Protection:
Wear appropriate safety glasses with side shields or chemical goggles as described by OSHA's eye and
face protection regulations in 29CFR 1910.133 or European Standard EN166.
Skin Protection:
Permeation resistant gloves (butyl rubber, nitrile, and polyvinyl alcohol). However, please note that
polyvinyl alcohol degrades in water. Cover as much of the exposed area as possible, with protective
clothing. If skin creams are used, keep the area covered by the cream to a minimum.

XI. Toxicological Information
For Monomeric and Polymeric Methylene Bisphenyl Isocyanate:
Oral LD50 (rats): >15,800 mg/kg
Dermal LD50 (rabbits): 7,900 mg/kg
Inhalation LC50: ~370-490 mg/m3 for an aerosol of polymeric MDI (Rats four hours). An LC50 (two
hours) of greater 400 mg/m3 was determined on a dust of monomeric MDI (Rats).
Acute Eye Irritation:
Liquid, aerosols or vapor are irritating and can cause tearing, reddening and swelling. If left untreated,
corneal damage can occur and injury is slow to heal. Damage, however is usually reversible.
Acute Skin Irritation:
Isocyanates react with skin protein and moisture and can cause irritation which may include the following
symptoms: reddening, swelling, rash, scaling or blistering. Cured material is difficult to remove.
Acute Dermal Toxicity:
Slight to moderate iritant. Primary dermal irritation scores are tyopically below 3.4/8.0 (Draize).
Acute Respiratory Irritation:
MDI has been shown to produce dermal sensitization in several species (guinea pigs, mice, rabbits, and
dogs). Intradermal or topical application followed by inhalation challenge have resulted in a respiration
sensitization response in guinea pigs. In addition there is some evidence to suggest that cross-
sensitization between different types of diisocyanates may occur.
Acute Ingestion Toxicity:
No hazard in normal industrial use.
Acute Inhalation Toxicity:
Can irritate mucous membranes, cause runny nose, sore throat, coughing, and other symptoms.
Acute Oral Toxicity:
ND
Chronic Toxicity:
Ina chronic inhalation study, rats were exposed to an aerosol of polymeric MDI for six hours per day, five
days per week for a period of two years. The exposure concentrations were 0, 0.2, 1.0 and 6.0 mg/m3.
Microscopic examination of tissues revealed the effects of irritation to the nasal cavity and lungs in
animals exposed to 1.0 and 6.0 mg/m3. The No Observable effect Level (NOEL) was 0.2 mg/m3. In the
same study, the occurrence of pulmonary adenomas (benign tumors) and a single pulmonary
adenocarcinoma (malignant tumor) was considered to be related to exposure. These tumors were
observed only in rats exposed to the high concentration of 6.0 mg/m3. No conclusive evidence has been
developed to indicate that either MDI or a similar product (a solution of MDI and a polyisocyanate

in humans.
