Isolate fire area and deny unnecessary entry. Stay upwind. Keep out of low areas where gases (fumes) can accumulate. Water is not recommended but may be applied in very large quantities as a fine spray when other extinguishing agents are not available. Contain fire water run-off if possible. Do not use direct water stream. May spread fire. Fight fire from protected location or safe distance. Consider use of unmanned hose holder or monitor nozzles. Use water spray to cool fire exposed containers and fire affected zone until fire is out. Immediately withdraw all personnel from area in case of rising sound from venting safety device or discoloration of the container. Move container from fire area if this is possible without hazard. Protective Equipment for Fire Fighters: Wear positive-pressure Self-Contained Breathing Apparatus, “SCBA” and protective fire fighting clothing (includes fire fighting helmet, coat, pants, boots, and gloves). Avoid contact with this material during fire fighting operations. If contact is likely, change to full chemical resistant clothing with SCBA. This will not provide sufficient fire protection; consider fighting fire from a remote location. For protective equipment in post-fire or non-fire clean-up situations, refer to the relevant sections. Products of Combustion: Carbon Monoxide, Carbon Dioxide, Nitrogen Oxides of the form NOx and HCN. Protective Clothing (Fire): Splash goggles. Full suit. Boots. Gloves. Self-Contained Breathing Apparatus, “SCBA”, should be used to avoid inhalation of the product. Special Remarks on Fire Hazards: Reacts slowly with water to produce carbon dioxide which may rupture closed containers. This reaction accelerates at higher temperatures. Section 6: Accidental Release Measures SEE MATERIAL SAFETY DATA SHEET Section 8. Exposure controls, personal protection Small Spill and Leak: Clean-up should only be performed by trained personnel. People dealing with major spillages should wear full protective clothing including appropriate respiratory protection. Evacuate the area. Prevent further leakage, spillage or entry into drains. Large Spill and Leak: Contain and absorb large spillages onto an inert, non-flammable adsorbent carrier (such as earth or sand). Shovel into open-top drums or plastic bags for further decontamination, if necessary. Wash the spillage area clean with liquid decontaminant. Test atmosphere for MDI. Neutralize small spillages with decontaminant. Remove and properly dispose of residues. (See Section 13 for disposal considerations). Notify applicable government authorities if release is reportable. The CERCLA RQ for 4,4-MDI is 5,000 lbs. (see CERCLA in Section 15). Decontaminant: Preparation of Decontamination Solution: Prepare a decontamination solution of 0.2 – 0.5% liquid detergent and 3-8% concentrated ammonium hydroxide in water (5-10% sodium bicarbonate may be substituted for the ammonium hydroxide). Follow the precautions on the supplier’s material safety data sheets when preparing and using solution. Use of Decontamination Solution: Allow deactivated material SAFETY DATA SHEET Product Name: Base Seal® (Component ‘A’, Isocyanate) MSDS-A004 Page 4 of 9 to stand for at least 30 minutes before shoveling into drums. Do not tighten the bungs. Mixing with wet earth is also effective, but slower. Section 7: Handling and Storage Handling: Avoid contact with the product or reaction mixture. Use only with adequate ventilation to ensure that the occupational exposure limit is not exceeded. The efficiency of the ventilation system must be monitored regularly because of the possibility of blockage. Avoid breathing aerosols, mists and vapours. (See Section 8 – Exposure Control for details). Storage: Keep containers properly sealed and when stored indoors, in a well- ventilated area. Keep contents away from moisture. Due to reaction with water, and producing CO2 gas, a hazardous buildup of pressure could result if contaminated containers are re-sealed. Do not reseal contaminated containers. Uncontaminated containers, free of moisture, may be resealed only after placing under a nitrogen blanket. Do not store in containers made of copper, copper alloy or galvanized surfaces. Ideal storage temperature is 16-38°C (60-100°F). Keep stocks of decontaminant (See Section 6) readily available. Section 8: Exposure Controls and Personal Protection Ingredient: ACGIH TLV (8-hr. TWA) ppm U.S. OSHA PEL (8 hr. TWA) mg/m3 Methylene bisphenyl isocyanate (MDI): 0.005 ppm TWA 0.02 ppm Ceiling PEL’s are in accord with those recommended by OSHA. Preventive Measures: Conditions of use, adequacy of engineering or other control measures, and actual exposures will dictate the need for specific protective devices at your workplace. Engineering Controls: Use local exhaust ventilation to maintain airborne concentrations below the TLV. Suitable respiratory equipment should be used in cases of insufficient ventilation or where operational procedures demand it. For guidance on engineering control measures, refer to publications such as the ACGIH current edition of ‘Industrial Ventilation, a manual of Recommended Practice.” Personal Protection: Eyes: Chemical Safety goggles. If there is a potential for splashing, use a full face shield. Body and Hands: The following protective materials are recommended: Gloves (neoprene, nitril rubber or butyl rubber).

SAFETY DATA SHEET Product Name: Base Seal® (Component ‘A’, Isocyanate) MSDS-A004 Page 6 of 9 Section 11: Toxicological Information Toxicity to Animals: LD50 Rat Oral: >5000 mg/kg LD50 Rabbit Dermal: >5000 mg/kg LC50 Rat Respirable aerosol: 2240 mg/m3 1 hours LC50 Rat Respirable aerosol: 490 mg/m3 4 hours Inhalation: This product is a respiratory irritant and potential respiratory sensitizer. Repeated inhalation of vapor or aerosol at levels above the occupational exposure limit could cause respiratory sensitization. Symptoms may include irritation to the eyes, nose, throat, and lungs, possibly combined with dryness of the throat, tightness of chest and difficulty in breathing. The onset of the respiratory symptoms may be delayed for several hours after exposure. A hyper-reactive response to even minimal concentrations of MDI may develop in sensitized persons. Skin Contact: Moderate irritant. Repeated and/or prolonged contact may cause skin sensitization. There is limited evidence from animal studies that skin contact may play a role in respiratory sensitization. These results emphasize the need for protective clothing including gloves to be worn at all times when handling these chemicals or in maintenance work. Eye Contact: The vapour, aerosol, and liquid are irritants. Ingestion: Ingestion may cause irritation of the gastrointestinal tract. Based on the acute oral LD50, this product is considered practically non-toxic by ingestion. Carcinogenic Effects: The ingredients of this product are not classified as carcinogenic by ACGIH or IARC, not regulated as carcinogens by OSHA, and not listed as carcinogens by NTP. Mutagenic Effects: There is no substantial evidence of mutagenic potential. Reproductive Effects: No adverse reproductive effects are anticipated. Teratogenic Effects: No birth defects were seen in two independent (rat) studies. Fetotoxicity was observed at doses that were extremely toxic (including lethal) to the mother. Fetotoxicity was not observed at doses that were not maternally toxic. The doses used in these studies were maximal respirable concentrations well in excess of the defined occupational limits. Remark: A study was conducted where groups of rats were exposed for 6 hours/day, 5 days/week for a lifetime to atmospheres of respirable polymeric MDI aerosol at concentrations of 0. 0.2, 1 or 6 mg/m3. No adverse effects were observed at 0.2 mg/m3. At the 1 mg/m3 concentration, minimal nasal and lung irritant effects were seen. Only at the top concentration (6.0 mg/m3) was there an increased incidence of a benign tumor of the lung (adenoma). One malignant pulmonary tumor (adenocarcinoma) was seen in the 6.0 mg/m3 group. MDI administration to rats in this study did not change the distribution and SAFETY DATA SHEET Product Name: Base Seal® (Component ‘A’, Isocyanate) MSDS-A004 Page 7 of 9 incidence of tumors from those seen in control animals. The increased incidence of lung tumors is associated with prolonged respiratory irritation and the concurrent accumulation of yellow material in the lung. In the absence of prolonged exposure to high concentrations leading to chronic irritation and lung damage, it is highly unlikely that tumor formation will occur. (MDI). There are reports that chronic exposure to diisocyanates by inhalation may result in permanent decreases in lung function. Section 12: Ecological Information/Environmental Fate Ecotoxicity: Polymeric MDI. LC50 (Zebra Fish) >1000 mg/l. EC50 (Daphnia Magna) (24 hour) >1000 mg/l EC50 (E. Coli) >100 mg/l Environmental Fate and Distribution: It is unlikely that significant environmental exposure in the air or water will arise based on consideration of the production and use of the substance. Degradation & Persistence: Immiscible with water, but will react with water to produce inert and non-biodegradable solids.

Revision Date: July.1 , 2015 Prepared By: Icynene Telephone: 1.800.758.7325 Icynene spray foam insulation products have an excellent health and safety record spanning more than 350,000 projects over more than 25 years. Nonetheless, safe handling practices during and immediately following installation are required to eliminate the possibility of health effects from exposure to isocyanates. Asthma, other lung problems, and irritation of the nose and throat can result from inhalation of isocyanates. Direct contact with the skin and eyes can result in irritation. Different individuals will react differently to the same exposures; some will be more sensitive than others. Severe asthma attacks have been reported in some sensitized workers exposed repeatedly to isocyanates while not wearing proper protective equipment. Some reports indicate a reaction and sensitization can occur following a single, sustained occupational exposure to isocyanates without proper protective equipment above the OSHA permissible exposure limit. But sensitization might not occur immediately in some individuals. Consistent use of personal proper protective equipment to prevent exposure during spraying and within the 4 hour*-period after spraying is completed is critical to eliminating the health hazard. Once sensitization has occurred, a worker might not be able work safely with spray foam insulation again. Sprayers, sprayer helpers, and anyone else present during spraying or within 4 hours* after spraying is complete: You must wear proper Personal Protective Equipment (PPE) at all times during spray, including full-body-coverage, chemical-protective clothing and a NIOSH-certified respirator with fresh air supply. While spraying and for 4 hours* after spraying is completed, no one must be allowed within 50 feet of the sprayed foam without wearing this type of PPE at all times. Adequate active, negative pressure ventilation (exhaust fans) of the job site must be in place during spray and for 4 hours* after spray is complete. For installations of low VOC products Icynene Classic Max and Icynene ProSeal in the United States only, re-entry and re-occupancy of the job site is permitted after 4 hours* provided that ventilation rates are followed as recommended on this page. Independent studies and third party toxicologist verification indicates that when the prescribed ventilation rates and periods are followed, Icynene spray foam insulation is safely cured.
