10.3 Possibility of hazardous reactions
Vapors may form explosive mixture with air. May react violently with incompatible materials. Hazardous polymerization will not occur.
10.4 Conditions to avoid
Avoid high temperatures, sources of ignition, hot surfaces and contact with incompatible materials. May be corrosive to lead, aluminum,
magnesium and platinum. Avoid use in confined areas. Avoid impact.
10.5 Incompatible materials
Strong oxidizing agents, strong mineral or organic acids, strong bases, halogenated hydrocarbons, zinc, any reactive metal that will displace
hydrogen, coatings, rubber, some plastics
10.6 Hazardous decomposition products
Thermal decomposition products include oxides of carbon, formic acid, formaldehyde, toxic fumes and gases.

11.2 Further information
Methanol (CAS #67-56-1) is slowly eliminated from the body; therefore, it can have cumulative toxicity effects with repeated exposures. Ingestion
of 100 - 125 ml (3 - 4 oz.) can be fatal or cause serious, irreversible injury such as blindness. May cause liver disorders (e.g. edema, proteinuria)
and damage. Significant exposure to methanol may adversely affect people with chronic disease of the respiratory system, central nervous
system, kidneys, liver, skin and/or eyes.
Methanol is not listed as a carcinogen by ACGIH, IARC, NTP or OSHA. Methanol is a potential hazard to the fetus. Developmental effects have
been observed in the offspring of rats and mice exposed to methanol by inhalation. These included skeletal, cardiovascular, urinary system and
central nervous system (CNS) malformations in rats and increased resorptions and skeletal and CNS malformations in mice.
Handle in accordance with good industrial hygiene and safety practice.
12.1 Toxicity
Methanol is dangerous to aquatic life in high concentrations. A study of methanol's toxic effects on sewage sludge bacteria reported little effect on
digestion at 0.1% while 0.5% methanol retarded digestion. Methanol will be broken down into carbon dioxide and water.

12.2 Persistence and degradability
This substance is readily biodegradable. When released into the air methanol is expected to exist in the aerosol phase and will be degraded from
