SECTION 2: Hazards identification

DANGER Polyisocyanurate foam panel. This product does not present an inhalation, ingestion, or contact health hazard unless subjected to operations such as sawing, sanding, or machining that result in the generation of airborne particulates (dusts). Exposure to high dust levels may irritate the skin, eyes, nose, throat, or upper respiratory tract. Inhalation of high amounts of dust over long periods may overload lung clearance mechanisms and make lungs more vulnerable to respiratory diseases. SECTION III: COMPOSITION AND INFORMATION ON HAZARDOUS INGREDIENTS NAME CAS # % WEIGHT EXPOSURE LIMIT (ACGIH) TLV-TWA TLV-STEL Polyisocyanurate Foam1 None 80-100 10 mg/m³ (breathable dust) Not established 1 f/cc for fibres longer than 5 µm Fibreglass1 65997-17-3 7-13 Not established with a diameter less than 3 µm Carbon Black1 1333-86-4 1-5 3 mg/m³ (breathable dust) Not established 1. The exposure to the product above the limits of exposure is not likely to occur considering its form (incorporated in the mixture) and the provided use. The limit of exposure is given for reference only. Effects of Short-Term (Acute) Exposure EYE CONTACT The dust may cause eye irritation. INHALATION Breathing dust from this product may cause a scratchy throat, Polyisocyanurate Foam, Fibreglass: Mechanical irritation, redness, congestion, and slight coughing. tearing, and blurred vision can occur if dusts generated from these products come into contact with eyes. (2) Polyisocyanurate Foam: Dust may cause transient mechanical irritation of the upper respiratory tract. (2) Carbon Black: Carbon black dust is not irritating to the eyes except as a “foreign object”. (1) Fibreglass: Airborne fragments of glass fibres may cause mechanical irritation of the upper respiratory tract, particularly mouth, nose and INGESTION throat; glass dust may cause transient irritation of the upper respiratory It is unlikely that toxic amounts of this product would be ingested with tract.

(1) Carbon Black: Carbon black does not appear to cause significant Effects of Long-Term (Chronic) Exposure harmful effects after a single short-term exposure, except general SKIN CONTACT effects that would be expected with any fine dust (high concentrations Polyisocyanurate Foam, Fibreglass: None known. can cause coughing and mild, temporary irritation). (1) Carbon Black: Fine particles can become embedded in the skin and SKIN CONTACT trapped in hair follicles causing discolouration (carbon black “tattoos”) Frequent or prolonged contacts may cause skin irritation. and follicular blackheads.

Normally the Under certain fire conditions, combustible gases can be generated dust is cleared gradually from the lungs and has no harmful effects. creating rapidly spreading, high intensity flames and dense, black However, high concentrations of dust can overwhelm the clearance smoke. Burning of this product can produce irritating and potentially capacity of the lungs, obstruct the lungs, and interfere with lung toxic fumes and gases, including carbon monoxide and carbon dioxide; function. Symptoms may include coughing, increased phlegm other undetermined hydrocarbon fractions could be released in small production, and shortness of breath.
