Warnings: DANGER! Flammable Gas. Vapors may cause flash fire. This product is extremely FLAMMABLE during dispensing. DO NOT SMOKE WHILE DISPENSING OR USE NEAR OPEN FLAME. Shut off pilot lights and sources of ignition until foam is tack free. KEEP AWAY FROM CHILDREN.Do not breathe vapors. Inhalation and skin exposure may cause sensitization. Ensure good ventilation. Open all windows and doors in the room. If no ventilation is available, wear a NIOSH approved respirator with an organic vapor and particulate filter (P-100). Contents under pressure. Do not puncture or incinerate. Do not store above 120F (49C) or in areas of high heat. The cured foam is combustible. Do not expose to temperatures above 240F (116C). Extremely sticky and very difficult to remove from skin and other surfaces. Prevent skin and eye contact. Wear gloves and protective eyewear. Protect work area with a drop cloth or newspaper. Shake vigorously for 30 seconds. SCREW threaded end of straw assembly securely onto valve. Dispense slowly. If product does not flow easily, do not force product from can. Familiarize yourself with foam by practicing on newspaper.CLEAN UP: If you get GREAT STUFF on your skin, remove excess carefully with a dry cloth, being careful not smear the foam to other unexposed areas. Wash with soap and water. Frequent application of petroleum jelly or vegetable oil may help sooth the skin. Cured foam must be mechanically removed or allowed to wear off in time. There are no solvents or cleansers that will dissolve the cured foam; using such solvents may cause harm and chemical burns. On solid surfaces, uncured foam dissolves with acetone. Test a hidden area before applying to the exposed area. Cured foam will discolor if exposed to ultraviolet light. Paint or coat foam for best results in outdoor applications.DO NOT OVERFILL. Fill openings less than 50 percent full. For large voids, mist water between foam applications to speed cure. Overfilling can buckle substrates. Overfilling the gap is common, but easy to remedy. Once dry, trim excess foam with any sharp knife or serrated blade.
Acute Health Effects: From MSDS:Hazards IdentificationEmergency OverviewColor: YellowPhysical State: FoamOdor: MildHazards of product:DANGER! Flammable gas - May cause flash fire. May cause allergic skin reaction. May cause allergic respiratory reaction. May cause eye irritation. May cause skin irritation. Vapor reduces oxygen available for breathing. May cause anesthetic effects. May cause respiratory tract irritation. Vapors may travel a long distance; ignition and/or flash back may occur. Evacuate area. Keep upwind of spill. Stay out of low areas. Aerosol cans exposed to fire can rupture becoming flaming projectiles. Elevated temperatures can cause hazardous polymerization. Toxic fumes may be released in fire situations. Containers are under high pressure. Avoid temperatures above 49 deg. C (120 deg. F).This product is a ***Hazardous Chemical*** as defined by the OSHA Hazard Communication Standard, 29 CFR 1910.1200.Potential Health EffectsEye Contact: May cause eye irritation. May cause slight temporary corneal injury.Skin Contact: Prolonged contact may cause moderate skin irritation with local redness. Material may stick to skin causing irritation upon removal. May stain skin.Skin Absorption: Prolonged skin contact is unlikely to result in absorption of harmful amounts.Skin Sensitization: Skin contact may cause an allergic skin reaction. Animal studies have shown that skin contact with isocyanates may play a role in respiratory sensitization.Inhalation: In confined or poorly ventilated areas, vapor can easily accumulate and can cause unconsciousness and death due to displacement of oxygen. Excessive exposure may cause irritation to upper respiratory tract (nose and throat) and lungs. May cause pulmonary edema (fluid in the lungs.) Effects may be delayed. May cause central nervous system depression. Symptoms of excessive exposure may be anesthetic or narcotic effects; dizziness and drowsiness may be observed. Excessive exposure may increase sensitivity to epinephrine and increase myocardial irritability (irregular heartbeats). Decreased lung function has been associated with overexposure to isocyanates.Respiratory Sensitization: May cause allergic respiratory response. MDI concentrations below the exposure guidelines may cause allergic respiratory reactions in individuals already sensitized. Asthma-like symptoms may include coughing, difficult breathing and a feeling of tightness in the chest.Occasionally, breathing difficulties may be life threatening.Ingestion: Low toxicity if swallowed. Small amounts swallowed incidentally as a result of normal handling operations are not likely to cause injury; however, swallowing larger amounts may cause injury. Observations in animals include: Gastrointestinal irritation.Medical Conditions Aggravated by Exposure: Excessive exposure may aggravate preexisting asthma and other respiratory disorders (e.g. emphysema, bronchitis, reactive airways dysfunction syndrome).
Chronic Health Effects: From MSDS:Tissue injury in the upper respiratory tract and lungs has been observed in laboratory animals after repeated excessive exposures to MDI/polymeric MDI aerosols. Contains component(s) which have been reported to cause effects on the following org
Carcinogenicity: Lung tumors have been observed in laboratory animals exposed to respirable aerosol droplets of MDI/Polymeric MDI (6 mg/m3) for their lifetime. Tumors occurred concurrently with respiratory irritation and lung injury. Current exposure guidelines are expect
First Aid: Eye Contact: Immediately flush eyes with water; remove contact lenses, if present, after the first 5 minutes, then continue flushing eyes for at least 15 minutes. Obtain medical attention without delay, preferably from an ophthalmologist.Skin Contact: Remove material from 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.Inhalation: Move person to fresh air. If not breathing, give artificial respiration; if by mouth to mouth use rescuer protection (pocket mask, etc). If breathing is difficult, oxygen should be administered by qualified personnel. Call a physician or transport to a medical facility.Ingestion: If swallowed, seek medical attention. Do not induce vomiting unless directed to do so by medical personnel.Notes to Physician: Maintain adequate ventilation and oxygenation of the patient. May cause asthma-like (reactive airways) symptoms. Bronchodilators, expectorants, antitussives and corticosteroids may be of help. 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. Exposure may increase ***myocardial irritability***. Do not administer sympathomimetic drugs such as epinephrine unless absolutely necessary. If you are sensitized to diisocyanates, consult your physician regarding working with other respiratory irritants or sensitizers. Although cholinesterase depression has been reported with this material, it is not of benefit in determining exposure and need not be considered in the treatment of persons exposed to the material. No specific antidote. Treatment of exposure should be directed at the control of symptoms and the clinical condition of the patient.
