Wear proper protective equipment and avoid contact with skin andinhalation of vapor. Conduct operations from upwind and evacuate
people downwind. Remove all sources of ignition. Keep away
personnel except for authorized ones from spillage area by
stretching ropes.

:

Attention should be given to avoid discharge of spilled productinto rivers and resulting environmental damage. When diluting
spill with large amounts of water, discharge of untreatedwastewater into the environment must be avoided.

Prevention Measures for
Secondary Accidents:

Remove nearby sources of ignition and prepare extinguishingmedia.

:

Wear proper protective equipment to avoid contact with skin or
inhalation of vapor. Fire is strictly prohibited.

7. Handling and storage
Handling

11. Toxicological information
Acute toxicity (oral)

Acute toxicity (dermal)
Acute toxicity (inhalation): Harmful if swallowed
rat LD50=6200mg/kghuman LD50=1400mg/kg
As the result of animal experiments, acute oral toxicity was notclassified, however, the toxic effects of methanol in primates ismore pronounced, therefore it was classified into category 4.
: No classification
rabbit LD50=15800mg/kg: No classification (gas)No classification (vapor)
Classification not possible (dust, mist): rat LC50>31500ppm/4h

Acute toxicity (vapor) Description
Skin corrosion/irritation:

Serious eye damage/irritation:

Respiratory sensitization
Skin sensitization::

Germ cell mutagenicity:

Carcinogenicity:

Classification not possible
Although there is an unpublished report that when applied to theskin of rabbits under occlusive conditions for up to 20-hour thesubstance was not irritating, classification was not possible due
to lack of data in a skin irritation test. As relevant information,although there is a report that application to rabbit skin for 24hour under occlusive conditions caused moderate skin irritation,
this irritation was probably a result of the defatting action ofmethanol.
Causes serious eye irritation
In a rabbit Draize test, mean scores of conjunctivitis were judged
to be 2 and higher (2.1) at 24, 48 and 72-hour after installation.
Chemosis (score of 2.00) observed up to 4-hour had decreased
significantly by 72-hour (score of 0.50). Since it is not clear
whether the effects reversed within 7 days, sub-categorization was
not performed. Based on the data, the substance was classified into
category 2A.
Classification not possible
No classification
Based on the description that Methanol has no skin sensitization bymaximization test using guinea pig, it was classified as "Noclassification".
No classification
Methanol is negative in mouse erythrocyte micronucleus tests (invivo somatic cell mutagenicity tests) by inhalation exposure and byintraperitoneal administration.
Classification not possible

Reproductive toxicity:

STOT-single exposure:

STOT-repeated exposure:

Aspiration hazard:

May damage fertility or the unborn childIn a developmental toxicity test by inhalation exposure to mice
during organogenesis period, fetal resorptions and exencephaly wereobserved. Additionally, similar effects including cleft palate werereported in other inhalation and oral exposure tests. For effectsof methanol on reproduction, scientific decisions concerning healthrisks are generally based on what is known as weight-of-evidence
approach. Recognizing the lack of human data and the clear
evidence of laboratory animal effects, it was concluded thatmethanol may adversely affect human development if exposures aresufficiently high. Based on the information, the substance wasconsidered to be a presumed human reproductive toxicant and it wasclassified into category 1B.
Causes damage to organs (central nervous system, visual organs,systemic toxicity)
May cause drowsiness or dizziness
The symptoms of acute poisoning from the substance include CNSdepression. Formate accumulates in the blood during a latency
period which leads to metabolic acidosis, visual impairment or eventotal blindness, headaches, dizziness, nausea, vomiting, Kussmaul
breathing and coma. In some cases death is the final outcome.
Further, CNS disorders, especially parkinsonism-like extrapyramidal
symptoms were reported. Morphological changes, necrosis in thewhite substance of the brain were demonstrated. Based on the human
information, the substance was classified into category 1 (centralnervous system). Additionally, the eye was regarded as a target
organ since visual impairment is a characteristic effect.
Additionally, systemic toxicity is regarded as a target organ basedon the reports of headache, nausea, vomiting, tachypnea and coma as
signs of metabolic acidosis. The effects of single exposures byinhalation include narcosis. As an acute toxicity in humans, anarcotic effect results from central nervous system depression.
Based on the data, the substance was classified into category 3(narcosis).
Causes damage to organs (central nervous system, visual organs)through prolonged or repeated exposure
Based on a report that the most noted health consequence of longerterm exposure to lower levels of methanol is a broad range ofocular effects, and that cases of chronic poisoning fromoccupational exposure to methanol were manifested by bilateralblindness, it was classified into category 1 (visual organs).
Additionally, based on the report that cases of chronic poisoning
from repeated exposure to methanol vapour are manifested byheadache, giddiness, insomnia, and gastric disturbances, it wasclassified into category 1 (central nervous system).
