2 / 10 PRIMARY ROUTES OF EXPOSURE : Eye, Skin, Inhalation HUMAN HEALTH HAZARDS

- ACUTE : EYE CONTACT : May cause irritation with prolonged contact. SKIN CONTACT : May cause irritation with prolonged contact. Toxic in contact with skin. Methanol may be absorbed through the skin and cause central nerv ous system effects which may result in permanent visual changes including blindness. INGESTION : Not a likely route of exposure. May cause nausea and vomiting. Can cause central nervous s ystem depression. 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 effect s and may result in permanent visual changes including blindness. INHALATION : Toxic by inhalation. AGGRAVATION OF EXISTING CONDITIONS : Skin contact may aggravate an existing dermatitis condition. 

### 4. FIRST AID MEASURES EYE CONTACT : Get medical attention. Immediately flush eye with water for at least 15 minutes while holding eyelids open. SKIN CONTACT : Immediately flush with plenty of water for at least 15 minutes. Use a mild soap if available. For a large splash, flood body u nder a shower. Get medical attention. Contaminated clothing, shoes, and leather goods must be discarded or cleaned before re

- use. INGESTION : Get immediate medical attention. Do not induce vomiting: contains petroleum distillates and/or aromatic sol ve nts. If conscious, washout mouth and give water to drink. INHALATION : Remove to fresh air, treat symptomatically. Get medical attention. NOTE TO PHYSICIAN : Based on the individual reactions of the patient, the physician's judgement should be used to control symptoms and clinical condition.

### 5. FIRE FIGHTING MEASURES FLASH POINT : 52.0 °F / 11.0 °C EXTINGUISHING MEDIA : Foam, Carbon dioxide, Dry powder, Other extinguishing agent suitable for Class B fires, For large fires, use water spray or fog, thoroughly drenching the burning material. Wa ter mist may be used to cool closed containers. UNSUITABLE EXTINGUISHING MEDIA : Do not use water unless flooding amounts are available. FIRE AND EXPLOSION HAZARD : Flammable Liquid; may release v apors that form flammable mixtures at or abov e the flash point. Vapors can trav el to a source of ignitio n and flash back. Em pty 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. SPECIAL PROTECTIVE EQUIPM ENT FOR FIRE FIGHTING : In case of fire, wear a full face positive

- pressure self contained breathing apparatus and protective suit. 

### 6. ACCIDENTAL RELEASE MEASURES PERSONAL PRECAUTIONS : Restrict access to area as appropriate until clean
- up operations are complete. Use personal protective equipment recommended in Section 8 (Exposure Controls/Personal Protection). Stop or reduce any leaks if it is safe to do so. Keep people away from and upwind of spill/leak. Ventilate spill area if possible. Remo ve sources of ignition. Ensure clean
- up is conducted by trained personnel only. Do not touch spilled material. Have emergency equipment (for fires, spills, leaks, etc.) readily available. N otify appropriate gov ernment, occupational health and safety and environmental authorities. METHODS FOR CLEANING UP : SMALL SPILLS: Soak up spill with absorbent material. Place residues in a suitable, covered, properly labeled container. W ash affect ed area. LARGE SPILLS: Contain liquid using absorbent material, by digging trenches or by diking. Reclaim into recovery or salvage drums or tank truck for proper disposal. Clean contaminated surfaces with water or aqueous cleaning agents. Contact an a pproved waste hauler for disposal of contaminated recovered ma terial. Dispose of material in compliance with regulations indicated in Section 13 (Disposal Considerations). ENVIRONMENTAL PRECAUTIONS : Prev ent material from entering sewers or waterways. 

### 7. HANDLING AND STORAGE HANDLING : Do not get in eyes, on skin, on clothing. Do not take internally. Use with adequate v entilation. Do not breathe vapors/gases/dust. Keep the containers closed when not in use. Have emergency equipment (for fire s, spills, leaks,
