==============================SECTION 4. FIRE & EXPLOSION DATA ============================================
FLASH POINT: >350 F (180 C)
FLAMMABLE LIMITS IN AIR MY VOLUME:
LOWER: N.E (Non-Volatile Fluid)
UPPER: N.E (Non-Volatile Fluid)
EXTINGUISHING MEDIA: Dry chemical extinguishers such as monoammonium phosphate, potassium sulfate, and potassium chloride. Additionally,
carbon dioxide, high expansion (proteinic) chemical foam, water spray for large fires.
SPECIAL FIRE FIGHTING PROCEDURES: If water is used, use large amounts, as the reaction between hot isocyanates and water
can be vigorous. Use self-contained breathing apparatus and body covering (protective clothing).
UNUSUAL FIRE AND EXPLOSION HAZARDS: Water contamination will produce carbon dioxide. DO NOT re-seal contaminated
containers as pressure buildup may rupture them.
============================== SECTION 5. REACTIVITY DATA ===============================================
STABILITY: Stable under recommended storage conditions
POLYMERIZATION: May occur with incompatible reactants, especially strong bases, water or temperatures over 400/F (204/C) may cause polymerization.
INCOMPATIBILITY (Materials to avoid): Water, acid, bases, metal compounds and surface active materials. Avoid water as it reacts to form CO2. The
combined effect of the CO2 and heat can produce enough pressure to rupture a closed container.
HAZARDOUS DECOMPOSITION PRODUCTS: Isocyanate vapor and mist, carbon dioxide, carbon monoxide, nitrogen oxides and traces of hydrogen
cyanide.
===============================SECTION 6. TOXICOLOGICAL PROPERTIES =======================================
ANIMAL TOXICITY:
ORAL, LD50 (Ingestion): >10,000 mg/kg (Rats)
DERMAL, LD50 (Skin Contact): >6,200 mg/kg (Rabbits)
INHALATION, LC50(4hr): Approx. 370-490 mg/Cubic Meter (Rats)
AQUATIC, LC50 (24 hr.): >500 mg/L (Daphnia, Limnea Invertebrates & Zebra Fish)
EYES: Slight to moderate irritation (Rabbits)
SKIN: Slight to moderate irritation (Rabbits)
OTHER: No conclusive evidence has been developed to indicate that MDI is a carcinogenic however this product may
contain one or more chemicals known to the state of Califonria to cause cancer, teratongenic or that it causes
reproductive effects in animals and humans. However, MDI has been reported by NIOSH to be mutagenic to
Salmonella typhimurium Bacteria. There is not full agreement in the scientific community as to the safety of
human cancer risks.
HUMAN EFFECTS OF OVER-EXPOSURE:
INHALATION: May cause respiratory sensitization in susceptible individuals. At room temperature, vapors are minimal due to low vapor pressure. If heated or
sprayed excessive concentrations are attainable that could be hazardous on single exposure. Excessive exposure may cause irritation of the eyes, upper
respiratory tract and lungs. Effects may be delayed. Decreased ventilator capacity has been associated with exposure to similar isocyanate; it is possible that
exposure to MDI may cause impairment of lung function.
SKIN: May cause allergic skin reaction in susceptible individuals. Prolonged or repeated contact may cause skin irritation. May stain the skin.
INGESTION: This is not considered a common occupation route of exposure and single dose toxicity is low.
TLV is .005 PPM TWA
THRESHOLD LIMIT VALUE (ACGIH):
PEL is .02 PPM
PERMISSIBLE EXPOSURE LIMIT (OSHA):
HTS 7000 SERIES A MATERIAL SAFETY DATA SHEET PAGE 2
============================ SECTION 7 PREVENTATIVE MEASURES ==========================================
EYE PROTECTION: Liquid chemical goggles or full-face shield. No contact lenses should be worn.
SKIN PROTECTION: Chemical resistant gloves, such as natural rubber or polyvinyl alcohol. Cover as much exposed skin as possible with appropriate clothing. If
skin creams are used, keep the area covered by the cream to a minimum.
RESPIRATORY PROTECTION: This product has demonstrated no observable effects at room temperature, however, atmospheric levels should be
maintained. In addition, with any isocyanate in spray, pour, injection , confined applications or emergency situation where airborne particulate or aerosol are
generated a NIOSH app roved, full face mask supplied air resp irator must be provided.
VENTILATION: Natural or mechanical. Local exhaust will keep the TLV below minimum in most cases. Spills or other emergencies may require more forceful
ventilation means.
OTHER: Safety showers and eye wash stations should be provided in all work areas. All employees should be properly trained.
LEAK AND SPILL PROCEDURES
MINOR SPILLS: Contain the spilled material and then cover with a loose, absorbent material such as oil dry, vermiculite, sawdust. Shovel waste material into
proper waste containers. DO NOT make pressure tight. Transport to a well-ventilated area and treat with a neutralizing solution consisting of a mixture of
water and 3-8% concentrated ammonium hydroxide or 5-10% sodium carbonate. Add about 10 parts of neutralizer per part of isocyanate with mixing. Allow to stand
48 hours allowing evolved CO2 to escape.
MAJOR SPILLS: Call Hesterman Technical Services immediately 306-721-1339. If it is a transportation spill, notify CANUTEC @ 613-996-6666.
Evacuate and ventilate spill area. Dike spill to prevent entry into the environment. Wear full protective equipment, including respiratory
protection, during clean up.
IF TEMPORARY CONTROL OF ISOCYANATE VAPOR IS REQUIRED: A blanket of protein may be placed over the spill. Large quantities may be pumped
into closed, but not sealed, containers for disposal. Clean up decontaminate area using water/ammonia solution with 1-2%-added detergent, letting it
stand over affected area for at least 10 minutes. Cover mops, brooms, etc. used for this with plastic and dispose of properly often by incineration.
WASTE DISPOSAL METHODS: Waste material may be incinerated at proper facilities or disposed of under local, provincial, state or federal regulations
controlling environmental protection.
SPECIAL PRECAUTIONS & STORAGE DATA
Storage Temperature (min/max): 65/F (18/C) to 75/F (24/C)
Average Shelf Life: 6 Months from date of manufacturing
Special Sensitivity (heat, light, moisture: This product is reactive with water. Containers should be tightly sealed to prevent moisture contamination.
A nitrogen blanket should be used for bulk storage. Store at 65/F - 75/F. Protect from freezing.
Precautions in handling & Storage: If contamination of the MDI is suspected, DO NOT re-seal container because of possible rupture due to CO2
pressure buildup. Always slowly vent container when opening to relieve any pressure buildup.
