Fresh air, rest. Artificial respiration may be needed. Refer for medical attention.
Remove contaminated clothes. Rinse skin with plenty of water or shower.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.

Most important symptoms/effects, acute and delayed
Harmful if inhaled or swallowed. Vapor or mist is irritating to the eyes, mucous membrane and upper respiratory tract and skin. Narcotic effects and dermititis. (USCG, 1999)
Indication of immediate medical attention and special treatment needed, if necessary
Methylcyclohexane is absorbed by inhalation. a small fraction is exhaled, another fraction excreted in urine unchanged ... most that gets into blood is metabolized and excreted in urine as conjugates of glucuronic acid or sulfuric acid.
SECTION 5: Firefighting measures
Suitable extinguishing media
Foam, carbon dioxide, dry chemical
Specific hazards arising from the chemical
Special Hazards of Combustion Products: Vapor may travel considerable distance to a source of ignition and flashback containing explosion may occur during fire conditions. Forms explosive mixtures in air. (USCG, 1999)
Special protective actions for fire-fighters
Use powder, foam, carbon dioxide. In case of fire: keep drums, etc., cool by spraying with water.
SECTION 6: Accidental release measures
Personal precautions, protective equipment and emergency procedures
Personal protection: filter respirator for organic gases and vapours adapted to the airborne concentration of the substance. Ventilation. Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in dry sand or inert absorbent. Then store and dispose of according to local regulations. Do NOT wash away into sewer.
Environmental precautions
Personal protection: filter respirator for organic gases and vapours adapted to the airborne concentration of the substance. Ventilation. Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in dry sand or inert absorbent. Then store and dispose of according to local regulations. Do NOT wash away into sewer.
Methods and materials for containment and cleaning up
Absorb on paper. Evaporate on a glass or iron dish in hood. Burn the paper.
SECTION 7: Handling and storage
Precautions for safe handling
NO open flames, NO sparks and NO smoking. Closed system, ventilation, explosion-proof electrical equipment and lighting. Prevent build-up of electrostatic charges (e.g., by grounding). Do NOT use compressed air for filling, discharging, or handling. Use non-sparking handtools. Handling in a well ventilated place. Wear suitable protective clothing. Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Use non-sparking tools. Prevent fire caused by electrostatic discharge steam.
Conditions for safe storage, including any incompatibilities
Fireproof. Separated from strong oxidants.Storage rooms should be bunded to prevent the spread of escaping liquid & electrical installations should be of flameproof type.

SECTION 10: Stability and reactivity
Reactivity
1200 ppm [Based on 10% of the lower explosion limit for safety considerations even though the relevant toxicological data indicated that irreversible health efects or impairment of escape existed only at higher concentrations.]
Reacts violently with strong oxidants. This generates fire and explosion hazard.
Chemical stability
no data available
Possibility of hazardous reactions
DANGEROUS /FIRE HAZARD/ WHEN EXPOSED TO HEAT, FLAME, OR OXIDIZERSThe vapour is heavier than air and may travel along the ground; distant ignition possible. As a result of flow, agitation, etc., electrostatic charges can be generated.Saturated aliphatic hydrocarbons, such as METHYLCYCLOHEXANE, may be incompatible with strong oxidizing agents like nitric acid. Charring of the hydrocarbon may occur followed by ignition of unreacted hydrocarbon and other nearby combustibles. In other settings, aliphatic saturated hydrocarbons are mostly unreactive. They are not affected by aqueous solutions of acids, alkalis, most oxidizing agents, and most reducing agents.
