Inhalation: Start flushing while removing contaminated clothing. Wash affected areas thoroughly with soap and water. If irritation, redness, or a burning sensation develops and persists, repeat flushing and obtain medical attention. Skin Contact: Immediately flush eyes with running water for a minimum of 20 minutes. Hold eyelids open during flushing. If irritation persists, repeat flushing. Obtain medical attention IMMEDIATELY. Eye Contact: Do not attempt to give anything by mouth to an unconscious person. If victim is alert and not convulsing, rinse mouth out and give 1/2 to 1 glass of water to dilute material. IMMEDIATELY contact local Poison Control Centre. Vomiting should only be induced under the direction of a physician or a poison control centre. If spontaneous vomiting occurs, have victim lean forward with head down to avoid breathing in of vomitus, rinse mouth and administer more water. IMMEDIATELY transport victim to an emergency facility. Ingestion: Treat symptomatically. This product contains materials that may cause severe pneumonitis if aspirated. If ingestion has occurred less than 2 hours earlier, carry out careful gastric lavage; use endotracheal cuff if available, to prevent aspiration. Observe patient for respiratory difficulty from aspiration pneumonitis. Give artificial resuscitation and appropriate chemotherapy if respiration is depressed. Petroleum Naphtha or Xylene : Vasopressor drugs (e.g. epinephrine, ephedrine etc.) should not be given on their own as there may be danger of cardiac arrhythmia. (7) Medical conditions that may be aggravated by exposure to this product include neurological and cardiovascular disorders, diseases of the skin, eyes or respiratory tract, preexisting liver and kidney disorders. Note to Physicians: 3. HAZARDS IDENTIFICATION Harmful if inhaled, absorbed through skin, or swallowed. Causes skin and eye irritation. High vapour concentrations may cause drowsiness. May cause teratogenic effects. See "Other Health Effects" Section. Combustible liquid and vapour. May cause flash fire or explosion. Can decompose at high temperatures forming toxic gases. Contents may develop pressure on prolonged exposure to heat. EMERGENCY OVERVIEW: POTENTIAL HEALTH EFFECTS Contact with mist or spray may cause irritation of mucous membranes, coughing and difficulty in breathing. See "Other Health Effects" Section. Inhalation: Brief contact causes irritation (itching, local redness or possible swelling). Prolonged and repeated contact may lead to dermatitis. May cause defatting, drying and cracking of the skin. Skin contact can cause irritation, especially under the finger nails (and other confined spaces such as under rings or watch bands). Skin Contact: Prolonged or wide spread skin contact may result in the absorption of potentially harmful amounts of material. Skin Absorption: Splashes to the eye may cause irritation, redness and pain. Vapours from this product are irritating to the eyes. Eye Contact: This product causes irritation, a burning sensation of the mouth and throat and abdominal pain. Ingestion: Effects (irritancy) on the skin and eyes may be delayed, and damage may occur without the sensation or onset of pain. Strict adherence to first aid measures following any exposure is essential. May cause lachrymation (excessive tears), conjunctivitis, central nervous system (CNS) depression, liver damage, kidney damage, cardiac arrhythmia, hearing loss, and death. CNS depression is characterized by headache, dizziness, drowsiness, nausea, vomiting and incoordination. Severe overexposures may lead to coma and possible death due to respiratory failure. Liver damage is characterized by the loss of appetite, jaundice (yellowish skin colour), and occasional pain in the upper left-hand side of the abdomen. Signs and symptoms of kidney damage generally progress from oliguria, to blood in the urine, to total renal failure. Petroleum Naphtha or Xylene may sensitize heart muscle causing cardiac arrhythmia, in rare cases. Aromatic hydrocarbons pose potential human health risks which may vary from person to person. Solvent abusers exposed to high doses of aromatic solvents show signs of hearing loss as well as damage to the brain, liver and kidney.

FIRE-FIGHTING MEASURES Flashpoint (°C) AutoIgnition Temperature (°C) LEL UEL Flammability Limits in Air (%): >30. (Estimated) 224 (Estimated) 1 (3) 6.6. (3) B-3: Combustible Liquid Flammability Class (WHMIS): Thermal decomposition products are toxic and may include oxides of carbon, nitrogen and irritating gases. Hazardous Combustion Products: Vapours from this product are heavier than air, and may "travel" to a source of ignition (eg. pilot lights, heaters, electric motors) some distance away, and then "flash back" to the point of product discharge causing an explosion and fire. Vapours may form explosive mixtures with air. Closed containers exposed to heat may explode. Spilled material may cause floors and contact surfaces to become slippery. Enforce NO SMOKING rules. Unusual Fire or Explosion Hazards: Not expected to be sensitive to mechanical impact. Sensitivity to Mechanical Impact: Not available. Rate of Burning: Not available. Explosive Power: Expected to be sensitive to static discharge when vapours are present between the lower and upper explosive limits. Sensitivity to Static Discharge: EXTINGUISHING MEDIA Use carbon dioxide or dry chemical media for small fires. If only water is available, use it in the form of a fog. This material may produce a floating fire hazard in extreme fire conditions. Fire Extinguishing Media: FIRE FIGHTING INSTRUCTIONS Use water spray to cool fire-exposed containers or structures. Use water spray to disperse vapours; re- ignition is possible. Isolate materials that are not involved in the fire and protect personnel. The heat from a fire can cause a build-up of pressure inside the containers which may rupture. Cool containers with flooding quantities of water until well after the fire is out. (4) Instructions to the Fire Fighters: Use self-contained breathing apparatus and protective clothing. Fire Fighting Protective Equipment: 6. ACCIDENTAL RELEASE MEASURES Information in this section is for responding to spills, leaks or releases in order to prevent or minimize the adverse effects on persons, property and the environment. There may be specific reporting requirements associated with spills, leaks or releases, which change from region to region. In all cases of leak or spill contact vendor at Emergency Number shown on the front page of this MSDS. Utilize a spill kit, if available. Wear protective clothing. Do not use combustible materials such as sawdust as an absorbent. Recover spilled material on non-combustible absorbents, such as sand or vermiculite, and place in covered containers for disposal. Use spark-resistant tools. Eliminate all sources of ignition. Collect product for recovery or disposal. For release to land, or storm water runoff, contain discharge by constructing dykes or applying inert absorbent; for release to water, utilize damming and/or water diversion to minimize the spread of contamination. Ventilate enclosed spaces. Notify applicable government authority if release is reportable or could adversely affect the environment. Containment and Clean-Up Procedures: 7. HANDLING AND STORAGE HANDLING Ground and bond equipment and containers to prevent a static charge buildup. Use spark-resistant tools and avoid "splash-filling" of containers. Use normal "good" industrial hygiene and housekeeping practices. Drums which have been exposed to heat may be under internal pressure. These should be cooled and carefully vented before opening. A face shield and apron should be worn. Vent container frequently, and more often in warm weather, to relieve pressure. Handling Practices: See Section 8, "Engineering Controls". Ventilation Requirements: Unimark CB Petroleum Marker, Liquid Brenntag Canada Inc. Date of Revision: 2007 January 17 WHMIS Number : 00066314 Page 4 of 7 Use only with adequate ventilation and avoid breathing vapours or mists. Avoid contact with eyes, skin or clothing. Wash thoroughly with soap and water after handling. Wash contaminated clothing thoroughly before re-use. Absorption via contact with skin, eyes and mucous membranes can contribute to the overall exposure. Consider measures to prevent absorption by these routes. Store wiping rags and similar material in metal cans with tight fitting lids. Other Precautions: STORAGE See below. Storage Temperature (°C): Ventilation should be explosion proof. Ventilation Requirements: Store in a cool, well-ventilated area. Keep away from heat, sparks and flames. Keep containers closed. Do not expose sealed containers to temperatures above 40° C. Protect from direct sunlight. Protect against physical damage. Minimum pumping temperature: - 25. Storage Requirements: Attacks some types of rubber, plastics and coatings. Confirm suitability of any material before using. Special Materials to be Used for Packaging or Containers: 8. EXPOSURE CONTROLS / PERSONAL PROTECTION Recommendations listed in this section indicate the type of equipment, which will provide protection against overexposure to this product. 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 Local exhaust ventilation required. Ventilation should be explosion proof. Make up air should be supplied to balance air that is removed by local or general exhaust ventilation. Ventilate low lying areas such as sumps or pits where dense vapours may collect. For personnel entry into confined spaces (i.e. bulk storage tanks) a proper procedure must be followed. It must include consideration of, among other things, ventilation, testing of tank atmosphere, provision and maintenance of SCBA, and emergency rescue. Use the "buddy" system. The second person should be in view and trained and equipped to execute a rescue. (4) Engineering Controls: PERSONAL PROTECTIVE EQUIPMENT (PPE) Safety glasses with side shields are recommended to prevent eye contact. Use full face-shield or chemical safety goggles when there is potential for contact. Contact lenses should not be worn when working with this material. Eye Protection: Gloves and protective clothing made from neoprene or nitrile rubber should be impervious under conditions of use. Attacks some types of rubber, plastics and coatings. Prior to use, user should confirm impermeability. Discard contaminated gloves. Skin Protection: No specific guidelines available. Do not use compressed oxygen in hydrocarbon atmospheres. A NIOSH/MSHA-approved air-purifying respirator equipped with organic vapour cartridges for concentrations up to 900 ppm organic vapours. An air-supplied respirator if concentrations are higher or unknown. If while wearing a respiratory protection, you can smell, taste or otherwise detect anything unusual, or in the case of a full facepiece respirator you experience eye irritation, leave the area immediately. Check to make sure the respirator to face seal is still good. If it is, replace the filter, cartridge or canister. If the seal is no longer good, you may need a new respirator. (4) Immediately Dangerous to Life and Health (IDLH) value: 900 ppm. (4) The purpose of establishing an IDLH value is to ensure that the worker can escape from a given contaminated environment in the event of failure of the most protective respiratory equipment. In the event of failure of respiratory protective equipment, every effort should be made to exit immediately. (4) Respiratory Protection: Wear an impermeable apron and boots. Locate safety shower and eyewash station close to chemical handling area. Take all precautions to avoid personal contact. Clothing and footwear that is fire retardant and dissipates static electrical charges should be worn when handling flammable materials. Natural fibers (cotton, wool, leather and linen) should be selected in favour of synthetic materials (rayon, nylon and polyester).

Decomposition or Combustion Products: Unimark CB Petroleum Marker, Liquid Brenntag Canada Inc. Date of Revision: 2007 January 17 WHMIS Number : 00066314 Page 6 of 7 Xylene : Exposure to other solvents, (benzene, toluene and ethanol) slows the rate of clearance of xylenes from the body, thus enhancing its toxic effects. (4) Ethylbenzene : The toxicity of Ethyl Benzene can probably be increased by exposure to alcohols or other chemicals which inhibit its break down in the liver. (4) Synergistic Materials: Xylene : Results of short-term studies on human volunteers indicate that Xylene can cause neurobehavioral effects such as impaired short-term memory and impaired reaction time and alterations on body balance. (4) Application of Xylene caused slight to mild eye irritation when tested in rabbits. A single application of Xylenes caused skin irritation and swelling in rabbits and guinea pigs. Hearing loss, mainly at mid- frequencies, has been observed in rats following short term exposure to Xylene. No harmful reproductive nor mutagenic effects were noted. (4) In three studies, fetotoxic effects (delayed ossification and behavioral effects) were observed in the offspring of rats exposed by inhalation to 500 ppm mixed Xylenes with up to 20 % Ethylbenzene. In another study, fetoxicity (decreased weight) was observed in the female offspring of rats exposed to 500 ppm mixed Xylenes with 12.8 % Ethylbenzene. No signs of maternal toxicity was observed. (4) Other Studies Relevant to Material: 12. ECOLOGICAL INFORMATION Not available. Low acute toxicity to aquatic organisms. Ecotoxicity: This product has low mobility in soil. Volatalizes rapidly.
