COMPOSITION/INFORMATION ON INGREDIENTS INGREDIENT NAMECAS NUMBERWEIGHT %Dichloromethane 75-09-2 100 Component Information/Information on Non-Hazardous Components This product is considered to be hazardous according to the criteria specified in 29 CFR (Hazard Communication Standard) and the Canadian Controlled Product Regulations.

3 Trace impurities and additional Material names not listed above may also appear in Section 15 toward the end of the MSDS. These materials may be listed for local "Right-To-Know" compliance and for other reasons. 3. HAZARDS IDENTIFICATION EMERGENCY OVERVIEW: This product is a clear liquid. Has a sweet, mild odor. Not flammable. The product causes irritation of eyes, skin and mucous membranes. Harmful by inhalation, in contact with skin and if swallowed. May be fatal if inhaled. Causes headache, drowsiness or other effects to the central nervous system.

4 Limited evidence of a carcinogenic effect. Do not allow product to contact skin, eyes and clothing. Do not breathe vapours. Current Issue Date: January 9, 2006 Material Safety data Sheet Dichloromethane MSDS Number: BDH-120 Page 2 of 9 POTENTIAL HEALTH HAZARDS SKIN: Irritating to skin. If liquid remains on skin, can cause skin burns. Skin absorption may cause toxic effects similar to those described for inhalation. Repeated or extended contact may cause erythema (reddening of the skin) or dermatitis, resulting from a defatting action on tissue.

5 EYES: Irritating to eyes. Symptoms include itching, burning, redness and tearing. Corneal injury may occur. INHALATION: Harmful by inhalation. Vapours may cause drowsiness and dizziness. Inhalation of high vapour concentrations can cause CNS-depression and narcosis. Severe overexposure may produce more serious symptoms, including coma and risk of kidney damage. Exposure to high concentrations may result in central nervous system depression and respiratory failure and death possibly due to increased carboxyhemoglobin levels in the blood.

6 INGESTION: Harmful if swallowed. Ingestion may cause burning sensation in the mouth, throat and stomach and gastrointestinal disturbances. Ingestion of this product may result in central nervous system effects including headache, sleepiness, dizziness, slurred speech and blurred vision. DELAYED EFFECTS: Repeated or prolonged exposure may cause damage to the blood, heart, liver and kidney. Chronic exposure may cause headache, mental confusion, depression, bronchitis, loss of appetite, nausea, lack of balance, and visual disturbances.

7 Exposure to high concentrations may result in increased carboxyhemoglobin levels in the blood, which can lead to central nervous system depression and respiratory failure and death. MEDICAL CONDITIONS AGGRAVATED BY EXPOSURE: Pre-existing respiratory diseases, eye, blood, liver or kidney dysfunctions, or central nervous system disorders may be aggravated by exposure. Ingredients found on one of the OSHA designated carcinogen lists are listed below. INGREDIENT NAMENTP STATUSIARC STATUSOSHA LISTD ichloromethane (75-09-2) Reasonably Anticipated To Be A Carcinogen (Possible Select Carcinogen) Group 2B (possibly carcinogenic to humans) Carcinogen 4.

8 FIRST AID MEASURES SKIN: Wash off immediately with soap and plenty of water. Take off contaminated clothing and shoes immediately. Wash contaminated clothing before re-use. Obtain medical attention. EYES: Rinse immediately with plenty of water, also under the eyelids, for at least 15 minutes. Obtain medical attention. INHALATION: Move to fresh air in case of accidental inhalation of vapours. If not breathing, give artificial respiration. If breathing is difficult, give oxygen, provided a qualified operator is available. Call a physician immediately.

9 Current Issue Date: January 9, 2006 Material Safety data Sheet Dichloromethane MSDS Number: BDH-120 Page 3 of 9 INGESTION: DO NOT induce vomiting. Immediate medical attention is required. ADVICE TO PHYSICIAN: Treat symptomatically. 5. fire FIGHTING MEASURES FLAMMABLE PROPERTIES FLASH POINT: Would not flash FLASH POINT METHOD: Closed Cup AUTOIGNITION TEMPERATURE: 1033 F (556 C) UPPER FLAME LIMIT (volume % in air): 19 LOWER FLAME LIMIT (volume % in air): 12 FLAME PROPAGATION RATE (solids): Not applicable OSHA FLAMMABILITY CLASS: Not applicable EXTINGUISHING MEDIA: Use alcohol-resistant foam, carbon dioxide (CO2) or dry chemical.

10 UNUSUAL fire AND EXPLOSION HAZARDS: Not flammable. Irritating and/or toxic gases may be emitted upon the product's decomposition. Hazardous combustion products may include carbon monoxide, carbon dioxide (CO2) phosgene, hydrogen chloride gas and chlorine gas. SPECIAL fire FIGHTING PRECAUTIONS/INSTRUCTIONS: Water may be ineffective. fire -fighters should wear self-contained, NIOSH-approved breathing apparatus and full protective clothing. fire or intense heat may cause violent rupture of packages. In the event of fire , cool tanks with water spray. Do not use a solid water stream as it may scatter and spread fire .
