Eye:  Eye contact (irritant).  Produces irritation, characterized by a burning sensation, redness, tearing, inflammation, and possible corneal injury.  May cause painful sensitization to light.

Ingestion:  May be fatal or cause blindness if swallowed.  May cause gastrointestinal irritation with nausea, vomiting and diarrhea.  May cause systemic toxicity with acidosis.  May cause central nervous system depression, characterized by excitement, followed by headache, dizziness, drowsiness, and nausea.  Advanced stages may cause collapse, unconsciousness, coma and possible death due to respiratory failure.  May cause visual impairment and possible permanent blindness.  May cause cardiopulmonary system effects.

Inhalation:  Harmful if inhaled.  May cause adverse central nervous system effects including headache, convulsions, and possible death.  May cause visual impairment and possible permanent blindness.  Causes irritation of the mucous membrane.

Potential Chronic Health Effects:

Slightly hazardous in case of skin contact (sensitizer).


MUTAGENIC Effects:  Mutagenic for mammalian somatic cells.  Mutagenic for bacteria and/or yeast.

TERATOGENIC EFFECTS:  Classified POSSIBLE for human.  Chronic exposure may cause reproductive disorders and teratogenic effects


Other Toxic Effects:  The substance is toxic to eyes.  Prolonged or repeated skin contact may cause dermatitis.  Chronic inhalation and ingestion may cause effects similar to those of acute inhalation and ingestion. The substance may be toxic to blood, kidneys, liver, brain, heart, peripheral nervous system, upper respiratory tract, skin, central nervous system (CNS), optic nerve.  Repeated or prolonged exposure to the substance can produce target organs damage.  Repeated exposure to a highly toxic material may produce general deterioration of health by an accumulation in one or many human organs.

Section 4: First Aid Measures

Eye Contact:

Check for and remove any contact lenses.  Immediately flush eyes with running water for at least 15 minutes, keep eyelids open.  Cold water may be used.  Get medical attention.

Skin Contact:

In case of contact, immediately flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes.  Cover the irritated skin with an emollient.  Cold water may be used.  Wash clothing before reuse.  Thoroughly clean shoes before reuse.  Get medical attention immediately.Serious Skin Contact:

Wash with a disinfectant soap and cover the contaminated skin with an anti-bacterial cream.  Seek immediate medical attention.


If inhaled, remove to fresh air.  If not breathing, give artificial respiration.  If breathing is difficult, give oxygen.  Get medical attention immediately.

Serious Inhalation:

Evacuate the victim to a safe area as soon as possible.  Loosen tight clothing such as a collar, tie, belt or waistband.  If breathing is difficult, administer oxygen.  If the victim is not breathing, perform mouth-to-mouth resuscitation.  WARNING:  It may be hazardous to the person providing aid to give mouth-to-mouth resuscitation when the inhaled material is toxic, infectious or corrosive.  Seek immediate medical attention.


If victim is conscious and alert, give 2-4 cupfuls of milk or water.  Do not induce vomiting unless directed to do so by medical personnel.  Never give anything by mouth to an unconscious person.  Loosen tight clothing such as a collar, tie, belt, or waistband.  Get medical attention immediately.

 Special Remarks on the Products of Biodegradation:

Methanol in water is rapidly biodegraded and volatilized.  Aquatic hydrolysis, oxidation, photolysis, adsorption to sediment, and bioconcentration are not significant fate processes.  The half-life of methanol in surface weater ranges from 24 hrs to 168 hrs.  Based on its vapor pressure, methanol exists almost entirely in the vapor phase in the ambient atmosphere.  It is degraded by reaction with photochemically produced hydroxyl radicals and has an estimated half-life of 17.8 days.  Methanol is physically removed from air by rain due to its solubility.  Methanol can react with NO2 in polluted to form methyl nitrate.  The half-life of methanol in air ranges from 71 hrs (3 days) to 713 hrs (29.7 days) based on photooxidation half-life in air.
