TWA(ppm)OSHA PELACGIH TLVM ethanol200 ppm200 ppmWaterNot EstablishedNot IDENTIFICATION / EMERGENCY OVERVIEWR outes of entry for methanol are primarily absorption through the skin, eye contact,inhalation, or ingestion. Industrial exposures are primarily vapor exposures and skin contact. Initial symptoms from ingestion or inhalation may be only mild intoxication, but may becomesevere after 12-18 hours. Toxic effects from repeated over exposure to methanol have anaccumulative affect the central nervous system, especially the optic nerve. These symptomsmay linger for several days after exposure. Methanol can seriously impair vision and maycause name : MethanolPAGE 2 OF 7 REVISION DATE: 05/23/2001 POTENTIAL HEALTH EFFECTS:EYE CONTACT: Methanol can seriously impair vision and may cause blindness.

3 Immediatesigns and symptoms include the following: vapors are slightly uncomfortableand splashes very irritating; irritation with painful burning or stingingsensation; watering of eyes; inflammation of the eyelids; eyes are sensitiveto and painful in the CONTACT: Direct skin contact with methanol may cause irritation, dermatitis, erythema,and scaling. Methanol is highly volatile and will produce a feeling of cold. Alcohols remove oils form the skin, which becomes dry and eventuallydevelops cracks or dermatitis. Methanol which can be absorbed by the skin,causes headache, fatigue, and reduction of visual : Sign and symptoms of acute poisoning include the following: slight irritationof the nose and eyes; head feels hot and face is flushed; excitability andtalkativeness; drunken behavior; staggering and lack of coordination;headache; mental confusion and visual disturbance; : Signs and symptoms of acute poisoning are gastrointestinal irritation; headfeels hot and face is flushed; excitability and talkativeness; drunkenbehavior; staggering and lack of coordination; headache; mental confusionand visual disturbance; AID MEASURESEYES: Remove the victim from the source of contamination and take him to thenearest eye wash, shower, or other source of clean water.

4 Gently rinse theaffected eye(s) with clean, lukewarm water for at least 15 minutes. Have thevictim lie or sit down and tilt his head back. Hold the eyelid(s) open and pourwater slowly over the eyeball(s) at the inner corners, letting the water run outof the outer corners. Ask the victim to look up, down and side to side as yourinse in order to better reach all parts of the eye(s). If the victim cannottolerate light, protect his eye(s) with a clean, loosely tied handkerchief orstrip of clean, soft cloth or bandage. Seek medical attention : Remove the victim from the source of contamination. Remove clothing,shoes, socks, and jewelry from the affected areas. Be careful not to get anyof the CHEMICAL on your skin or clothing. Wash the affected area with tepidwater. Dry the skin gently with a clean, soft towel.

5 Seek medical : Remove the victim from the contaminated area while protecting yourself fromexposure by wearing an appropriate respirator. Put a similar respirator onthe victim. Remove contaminated clothing and equipment, while wearinggloves, being careful not to contaminate yourself. Administer CPR ifnecessary. Seek medical attention : Remove the victim from the contaminated area to a quiet, well ventilatedarea. Call a poison control center, inform them of the CHEMICAL swallowedand follow their advice.

6 Water may beineffective in in-depth methanol fires . Fire fightersshould use self-contained breathing apparatus andprotective RELEASE MEASURESSPILL OR LEAK PROCEDURES: Eliminate all ignition sources. Stop spill source. Ifspill is small use absorbent material to soak up spill. Dike large spill areas. Recover large spills byrecovering the methanol or by diluting with water toreduce the fire hazard. Salvage the liquid by using arecommended absorbent material. Prevent methanolfrom entering sewers, drains, or waterways. Alwaysnotify proper authorities of DISPOSAL METHOD: Dispose of material in accordance with your local,state, federal or other applicable AND STORAGESTORAGE TEMPERATURE: Keep LIFE: SENSITIVITY: Methanol is a flammable / STORAGEPRECAUTIONS:Store containers in well-ventilated place.

7 Large volumestorage should be remote from inhabited buildings orstructures. Keep away from all sources of ignition.

9 Poison experimentally by skin contact. Moderately toxic experimentally by intravenous and intraperitoneal routes. Mildlly toxic by OFACUTE EXPOSURE:The main toxic effect is exerted upon the nervous system, particularly theoptic nerves and possible the retina which can progress to permanentblindness. Once absorbed, methanol is only very slowly resulting from massive exposures may last as long as 2-4 days. Inthe body, the products formed by its oxidation are formaldehyde and formicacid, both of which are toxic. Because of the slow elimination, methanolshould be regarded as a cumulative poison. Though single exposures tovapors may cause no harmful effect, daily exposure may result in theaccumulation of sufficient methanol in the body to cause : Gastrointestinal irritation; slight irritation of nose and eyes; head feels hotand face is flushed; excitability and talkativeness; drunken behavior;staggering and lack of coordination; headache; mental confusion and visualdisturbance; EFFECTS: Methanol can seriously impair vision.

10 It may cause blurred vision,constricted visual fields, blindness, changes in color perception, doublevision, and general visual disturbances. Eye examinations have shownsluggish pupils, pallid optic discs, retinal edema, papilledema, hyperemia tothe optic discs with blurred edges and dilated veins. 1200 ppm to 8300 ppm: visual disturbances, dilated unreactive pupils and dim EFFECTS: Skin exposure may cause irritation and dermatitis. Poison experimentally byskin contact. Skin - rabbit: LD50: 15,800 mg/kgACUTE ORALEFFECTS:Ingestion of methanol may cause acidosis, headache, visual disturbances,dizziness, nausea and vomiting, severe upper abdominal pain, dilatednonreactive pupils and death.
