FIRST AID MEASURES Description of first aid measures General advice: First Aid responders should pay attention to self-protection and use the recommended protective clothing (chemical resistant gloves, splash protection). lf potential for exposure exists refer to Section 8 for specific personal protective equipment. lnhalation: Move person to fresh air. lf not breathing, give artificial respiration; if by mouth to mouth use rescuer protection (pocket mask, etc). lf breathing is difficult, oxygen should be administered by qualified personnel. Call a physician or transport to a medicalfacility. lf breathing has stopped, apply artifical respiration. Skin contact: Remove materialfrom skin immediately by washing with soap and plenty of water. Remove contaminated clothing and shoes while washing. Seek medical attention if irritation persists. Wash clothing before reuse. An MDI skin decontamination study demonstrated that cleaning very soon after exposure is important, and that a polyglycol-based skin cleanser or corn oil may be more effective than soap and water. Discard items which cannot be decontaminated, including leather articles such as shoes, belts and watchbands. Suitable emergency safety shower facility should be available in work area. Eye contact: lmmediately flush eyes with water; remove contact lenses, if present, after the first 5 minutes, then continue flushing eyes for at least 15 minutes. Obtain medicalattention without delay, preferably from an ophthalmologist. Suitable emergency eye wash facility should be immediately available. lngestion: lf swallowed, seek medical attention. Do not induce vomiting unless directed to do so by medical personnel. Most important symptoms and effects, both acute and delayed: Page 3 of 17 Product name: FROTH-PAKTM AF 60gal REF1.75 HFO ISO Spray Foam Sealant lssue Date: 0212312021 Aside from the information found under Description of first aid measures (above) and lndication of immediate medicalattention and specialtreatment needed (below), any additional important symptoms and effects are described in Section 11: Toxicology lnformation. lndication of any immediate medical attention and special treatment needed Notes to physician: Maintain adequate ventilation and oxygenation of the patient. May cause respiratory sensitization or asthma-like symptoms. Bronchodilators, expectorants and antitussives may be of help. Treat bronchospasm with inhaled beta2 agonist and oral or parenteral corticosteroids. Respiratory symptoms, including pulmonary edema, may be delayed. Persons receiving significant exposure should be observed 24-48 hours for signs of respiratory distress. lf you are sensitized to diisocyanates, consult your physician regarding working with other respiratory irritants or sensitizers. Exposure may increase "myocardial irritability". Do not administer sympathomimetic drugs such as epinephrine unless absolutely necessary. Treatment of exposure should be directed at the control of symptoms and the clinical condition of the patient. Excessive exposure may aggravate preexisting asthma and other respiratory disorders (e.9. emphysema, bronchitis, reactive ainrvays dysfunction syndrome). 5. FIREFIGHTING MEASURES Suitable extinguishing media: Water fog or fine spray. Dry chemical fire extinguishers. Carbon dioxide fire extinguishers. Foam. Alcohol resistant foams (ATC type) are preferred. General purpose synthetic foams (including AFFF) or protein foams may function, but will be less effective. Unsuitable extinguishing media: Do not use direct water stream. May spread fire. Special hazards arising from the substance or mixture Hazardous combustion products: During a fire, smoke may contain the original material in addition to combustion products of varying composition which may be toxic and/or irritating. Combustion products may include and are not limited to: Nitrogen oxides. lsocyanates. Hydrogen cyanide. Carbon monoxide. Carbon dioxide. Hydrogen halides. Halogenated hydrocarbons. Unusual Fire and Explosion Hazards: Some components of this product will burn in a fire situation. Product reacts with water. Reaction may produce heat and/or gases. This reaction may be violent. Container may rupture from gas generation in a fire situation. Blowing agent vaporizes quickly at room temperature. Violent steam generation or eruption may occur upon application of direct water stream to hot liquids. Dense smoke is produced when product burns. Advice for firefighters Fire Fighting Procedures: Keep people away. lsolate fire 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 large quantities as a fine spray when other extinguishing agents are not available. Do not use direct water stream. May spread fire. Fight fire from protected location or safe distance. Consider the use of unmanned hose holders or monitor nozzles. lmmediately withdraw all personnel from the 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. Use water spray to cool fire-exposed containers and fire-affected zone until fire is out. Contain fire water run-off if possible. Fire water run- off, if not contained, may cause environmental damage. Review the "Accidental Release Measures" and the "Ecological lnformation" sections of this (M)SDS. Special protective equipment for firefighters: Wear positive-pressure self-contained breathing apparatus (SCBA) and protective fire fighting clothing (includes fire fighting helmet, coat, trousers, boots, and gloves). Avoid contact with this material during fire fighting operations. lf contact is likely, Page 4 of 17 Product name: FROTH-PAKTM AF 60gal REF1.75 HFO ISO Spray Foam Sealant lssue Date: 0212312021 change to full chemical resistant fire fighting clothing with self-contained breathing apparatus. lf this is not available, wear full chemical resistant clothing with self-contained breathing apparatus and fight fire from a remote location. For protective equipment in post-fire or non-fire clean-up situations, refer to the relevant sections. 6. ACCIDENTAT RETEASE MEASURES Personal precautions, protective equipment and emergency procedures: lsolate area. Keep unnecessary and unprotected personnel from entering the area. Refer to section 7, Handling, for additional precautionary measures. Keep personnel out of low areas. Keep personnel out of confined or poorly ventilated areas. Keep upwind of spill. Ventilate area of leak or spill. Confined space entry procedures must be followed before entering the area. See Section 10 for more specific information. Spilled material may cause a slipping hazard. Use appropriate safety equipment. For additional information, refer to Section 8, Exposure Controls and Personal Protection.

Local exhaust ventilation may be necessary for some operations. Provide general and/or local exhaust ventilation to control airborne levels below the exposure guidelines. Exhaust systems should be designed to move the air away from the source of vapor/aerosol generation and people working at this point. The odor and irritancy of this material are inadequate to warn of excessive exposure, Lethal concentrations may exist in areas with poor ventilation. lndividual protection measures Eye/face protection: Use chemical goggles. Skin protection Hand protection: Use gloves chemically resistant to this material. Examples of preferred glove barrier materials include: Butyl rubber. Chlorinated polyethylene. Polyethylene. Ethylvinyl alcohol laminate ("EVAL"). Examples of acceptable glove barrier materials include: Neoprene. Nitrile/butadiene rubber ("nitrile" or "NBR"). Polyvinyl chloride ("PVC" or "vinyl"). Viton. NOTICE: The selection of a specific glove for a particular application and duration of use in a workplace should also take into account all relevant workplace factors such as, but not limited to: Other chemicals which may be handled, physical requirements (cuUpuncture protection, dexterity, thermal protection), potential body reactions to glove materials, as well as the instructions/specifications provided by the glove supplier. Other protection: Use protective clothing chemically resistant to this material. Selection of specific items such as face shield, boots, apron, or full body suit will depend on the task. Respiratory protection: Atmospheric levels should be maintained below the exposure guideline. When atmospheric levels may exceed the exposure guideline, use an approved air-purifying respirator equipped with an organic vapor sorbent and a particle filter. For situations where the atmospheric levels may exceed the level for which an air-purifying respirator is effective, use a positive-pressure air-supplying respirator (air line or self-contained breathing apparatus). For emergency response or for situations where the atmospheric level is unknown, use an approved positive-pressure self- contained breathing apparatus or positive-pressure air line with auxiliary self-contained air supply. ln confined or poorly ventilated areas, use an approved self-contained breathing apparatus or positive pressure air line with auxiliary self-contained air supply. For escape purposes, carry an approved air- purifying respirator on person at all times. The following should be effective types of air-purifying respirators: Organic vapor cartridge with a particu late pre-filter. 9.

STABITITY AND REACTIVITY
Reactivity: No data available
Chemical stability: Stable under recommended storage conditions. See Storage, Section 7.
Possibility of hazardous reactions: Can occur. Elevated temperatures can cause hazardous
polymerization. Polymerization can be catalyzed by: Strong bases. Water.
Gonditions to avoid: Exposure to elevated temperatures can cause product to decompose. Elevated
temperatures can cause pressure buildup in closed containers due to the release of blowing agents.
Generation of gas during decomposition can cause pressure in closed systems. Pressure build-up
can be rapid. Avoid moisture. Material reacts slowly with water, releasing carbon dioxide which can
cause pressure buildup and rupture of closed containers. Elevated temperatures accelerate this
reaction.

lncompatible materials: Avoid contact with: Acids. Alcohols. Amines. Water. Ammonia. Bases.
Metal compounds. Moist air. Strong oxidizers. Diisocyanates react with many materials and the rate
of reaction increases with temperature as well as increased contact; these reactions can become
violent. Contact is increased by stirring or if the other material mixes with the diisocyanate.
Diisocyanates are not soluble in water and sink to the bottom, but react slowly at the interface. The
reaction forms carbon dioxide gas and a layer of solid polyurea. Reaction with water will generate
carbon dioxide and heat. Avoid contact with metals such as: Aluminum. Zinc. Brass. Tin. Copper.
Galvanized metals. Avoid contact with absorbent materials such as: Moist organic absorbents. Avoid
unintended contact with polyols. The reaction of polyols and isocyanates generate heat.
Hazardous decomposition products: Decomposition products depend upon temperature, air supply
and the presence of other materials. Gases are released during decomposition.
