SECTION 2: Hazards identification

**EMERGENCY OVERVIEW** DANGER Corrosive. May cause tissue damage. Flammable. Toxic by inhalation, in contact with skin and if swallowed. Contains methanol. Methanol may cause central nervous system effects or permanent vision damage if inhaled, swallowed or absorbed through the skin in large amounts. This product contains naphthalene. The International Agency for Research on Cancer (IARC) has evaluated naphthalene and determined it to be possibly carcinogenic to humans (Group 2B, based on sufficient evidence in experimental animals and inadequate evidence in humans). Keep container tightly closed. Keep away from heat. Keep away from sources of ignition - No smoking. Do not get in eyes, on skin, on clothing. Do not take internally. Use with adequate ventilation. Avoid breathing vapor. If respiratory symptoms develop, remove to fresh air, rest, treat symptomatically. Get medical attention. In case of contact with eyes, rinse immediately with plenty of water and seek medical advice. After contact with skin, wash immediately with plenty of water. Use a mild soap if available. Wear a face shield. Wear chemical resistant apron, chemical splash goggles, impervious gloves and boots. Flammable Liquid; may release vapors that form flammable mixtures at or above the flash point. Vapors can travel to a source of ignition and flash back. Empty product containers may contain product residue. Do not pressurize, cut, heat, weld, or expose containers to flame or other sources of ignition. May evolve oxides of carbon (COx) under fire conditions. May evolve oxides of nitrogen (NOx) under fire conditions.

Health hazards

ACUTE EYE CONTACT Corrosive. Will cause eye burns and permanent tissue damage. SKIN CONTACT Corrosive; causes permanent skin damage. Harmful in contact with skin. Methanol may be absorbed through the skin and cause central nervous system effects which may result in permanent visual changes including blindness. INGESTION Corrosive; causes chemical burns to the mouth, throat and stomach. Toxic if swallowed. The main hazard of methyl alcohol arises from its misuse as a drinking substitute for ethyl alcohol. As little as 15 ml of 40% methyl alcohol may cause death. Sublethal doses may cause central nervous system effects and may result in permanent visual changes including blindness. INHALATION Elevated temperatures or mechanical action may form vapors, mists or fumes which may be irritating to the eyes, nose, throat and lungs. Toxic by inhalation. AGGRAVATION OF EXISTING CONDITIONS A review of available data does not identify any worsening of existing conditions. CHRONIC This product contains naphthalene. The International Agency for Research on Cancer (IARC) has evaluated naphthalene and determined it to be possibly carcinogenic to humans (Group 2B, based on sufficient evidence in experimental animals and inadequate evidence in humans).
