IV†††† FIRE AND EXPLOSION DATA

 

FLASH POINT:†† 151oFPemsky-Martin

EXTINGUISHING MEDIA:†† Dry chemical, carbon dioxide, high expansion (proteinic) chemical foam, 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.Product may float and can be reignited on water surface.Vapors are heavier than air and may travel a distance to a source of ignition and flash back.

UNUSUAL FIRE OR EXPLOSION HAZARDS:Combustible liquid. During fire, MDI vapors and other irritating, highly toxic gases may be generated by thermal decomposition or combustion.At temperatures greater than 400oF, 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.

 

V†††† REACTIVITY DATA

 

STABILITY:†† Stable under normal conditions

INCOMPATIBILITY (MATERIALS TO AVOID):†† Water, amines, strong bases, alcohols, heat, flame and contact with strong oxidizing agents.

HAZARDOUS POLYMERIZATION:†† May occur if in contact with moisture or other materials which react with isocyanates.May occur at high temperatures.

HAZARDOUS DECOMPOSITION PRODUCTS:†† By high heat and fire: carbon monoxide, oxides of nitrogen, traces of HCN, MDI vapors or aerosols, toxic oxides of carbon and sulfur, hydrocarbons and hydrocarbon derivatives.

 

VI†††† HEALTH HAZARD DATA

 

GENERAL:†† No toxicity information is available on this specific preparation; this health hazard assessment is based on information that is available on the properties of its components.

PRIMARY ROUTE(S) OF ENTRY:†† Skin; Inhalation

INHALATION:†† Although MDI is low in volatility, an inhalation hazard can exist from MDI aerosols or vapors formed during heating, foaming or spraying.

†† Acute Exposure.MDI vapors or mist at concentrations above the TLV can irritate the mucous membranes in the respiratory tract causing runny nose, sore throat, coughing, chest discomfort and reduced lung function.Persons with a preexisting, non-specific bronchial hyperactivity can respond to concentrations below the TLV with similar symptoms as well as asthma attack.Exposure well above the TLV may lead to bronchitis, bronchial spasm and pulmonary edema.These effects are usually reversible.Chemical or hypersensitive pneumonitis, with flu-like symptoms (e.g., chills, fever) has also been reported.These symptoms can be delayed up to several hours after exposure.Catalytic reformer distillate mist or vapor may cause respiratory tract irritation.High levels may cause giddiness, headache, dizziness, nausea, vomiting, incoordination and unconsciousness.

†† Chronic Exposure.As a result of previous repeated overexposures or a large single overdose, certain individuals develop isocyanate sensitization which will cause them to react to a later exposure to isocyanate at levels well below the TLV.Similar to many non-specific asthmatic responses, there are reports that once sensitized an individual can experience these symptoms upon exposure to dust, cold air or other irritants.Overexposure to isocyanates has also been reported to cause lung damage which may be permanent.Sensitization can be either temporary or permanent.

SKIN CONTACT:

†† Acute Exposure.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.

†† Chronic Exposure.Individuals in some cases may develop skin sensitization to isocyanate developing the acute exposure symptoms as a result of contact with very small amounts of liquid material or as a result of exposure to vapor.Repeated or prolonged exposure may cause irritation of hair follicles and blockage of sebaceous glands resulting in rash of pimples and spots.

EYE CONTACT:

†† Acute Exposure.Liquid, aerosols or vapors are irritating and can cause tearing, reddening and swelling.Untreated, corneal damage can occur and injury is slow to heal.However, damage is usually reversible.

†† Chronic Exposure.Prolonged or repeated exposure may cause conjunctivitis.

INGESTION:

†† Acute Exposure. Irritation of mucous membranes of throat, esophagus and stomach which may result in nausea and vomiting, depression may occur if absorbed. Central nervous system depression with extreme overexposure; effects may include anesthesia, coma, respiratory arrest and irregular heart rate.

†† Chronic Exposure.None found

CARCINOGENICITY None of the ingredients are listed by NTP, IARC, or regulated by OSHA as a carcinogen.

FIRST AID PROCEDURES:

†† Skin:Wash material off skin with plenty of soap and water.For severe exposures, get under safety shower after removing clothing, then get medical attention.For lesser exposure, seek medical attention if irritation develops or persists after the area is washed.Do not reuse clothing until cleaned.

†† Eyes:Flush with copious amounts of water for at least 15 minutes holding eyelids open.Get medical attention immediately.

†† Ingestion:DO NOT INDUCE VOMITING.Extreme care must be used to prevent aspiration.Do not give anything by mouth to an unconscious personGet medical attention immediately.

†† Inhalation:Move to area free of risk to further exposure.Administer oxygen or artificial respiration as needed.Get medical attention.

 

VII†††† SPILL OR LEAK PROCEDURES

 

STEPS TO BE TAKEN IN CASE MATERIAL IS RELEASED OR SPILLED:†† Remove all possible ignition sources.Evacuate and ventilate spill area; dike spill to prevent entry into water system; wear full protective equipment during cleanup.

Major Spill:If temporary control of isocyanate vapor is required, a blanket of protein foam may be placed over the spill.Large quantities may be pumped into closed, but not sealed container for disposal.

Minor Spill:Absorb material with sawdust or other absorbent, shovel into suitable unsealed containers, transport to well-ventilated area (outside) and treat with neutralizing solution:mixture of water (80%) with non-ionic surfactant Tergitol TMN-10 (20%), or: water (90%), concentrated ammonia (3-8%) and detergent (2%).Add about 10 parts neutralizer per part of spill.Allow to stand uncovered for 48 hours to let CO2 escape.

Clean-up:Decontaminate floor with decontaminating solution, letting stand for at least 15 minutes.

WASTE DISPOSAL METHOD:†† Waste must be disposed of according to federal, state and local environmental control regulations.Decontaminate containers prior to disposal.Empty containers should be crushed to prevent reuse.DO NOT HEAT OR CUT EMPTY CONTAINER WITH ELECTRIC OR GAS TORCH.Vapors and gases may be toxic.

 

VIII†††† SPECIAL PROTECTION

 

TLV OR SUGGESTED CONTROL VALUE:†† No ACGIH TLV or OSHA PEL is assigned to this mixture.Control of exposure to below the TLV for the ingredients (see Section II) may not be sufficient.Minimize exposure in accordance with good hygiene practice.ACGIH TLV for MDI is 0.005 ppm 8 hour TWA.The OSHA PEL for MDI is 0.02 ppm, ceiling.NIOSH recommends 0.005 ppm TWA and 0.02 ppm STEL.These control limits do not apply to previously sensitized individuals or those with existing respiratory disease.ACGIH TLV for catalytic reformer distillate is 5 mg(mineral oil mist)/m3 TWA; 10 mg (mineral oil mist)/m3 STEL.The OSHA PEL is 5 mg (mineral oil mist)/m3 TWA.

EYE PROTECTION:†† Liquid chemical goggles or full face shield.

SKIN PROTECTION:†† Gloves determined to be impervious under conditions of use.Depending on conditions of use, additional protection may be required such as apron, arm covers, or full body suit.Tests indicate that clothing constructed of butyl rubber, nitrile rubber and some neoprene garments have excellent resistance to permeation by MDI.

RESPIRATORY PROTECTION:†† Because of low vapor pressure, ventilation is usually sufficient to keep vapors below the TLV at room temperatures.Exceptions are when the material is heated, sprayed or used in a poorly ventilated area.In such cases or whenever concentrations exceed the TLV, use MSHA/NIOSH approved positive pressure supplied air respirator with a full facepiece or an air supplied hood.Air purifying (cartridge type) respirators are not approved for protection against isocyanates.

VENTILATION:†† Local exhaust should be used to keep airborne concentrations below the TLV whenever MDI is processed, heated or sprayed.

OTHER PROTECTIVE EQUIPMENT:†† Eyewash station and safety shower in work area.

 

IX†††† SPECIAL PRECAUTIONS

 

Store in tightly sealed containers to protect from atmospheric moisture.Temperatures below 55oF will cause a separation of the solution that is reversible by heating to about 75oF and tumbling or rolling container to mix.Material quality will deteriorate if stored at temperatures over 100oF (3-6 months).Educate and train employees in safe use of product.
