Section 4. First-Aid Measures

INHALATION: Move to fresh air. If breathing has stopped, give artificial respiration. If breathing is difficult, give oxygen.

EYES OR SKIN: Flush with running water for at least 15 min.; hold eyelids open if necessary. Remove and isolate contaminated clothing and shoes at the site.

INGESTION: DO NOT INDUCE VOMITING. If victim is unconscious or having convulsions, do nothing except keep victim warm. (USCG, 1999)

Section 5. Fire-Fighting Measures

Fire Extinguishing Agents: Dry chemical, CO2, or foam (USCG, 1999)

Section 6. Accidental Release Measures

Excerpt from ERG Guide 130 [Flammable Liquids (Water-Immiscible / Noxious)]:

IMMEDIATE PRECAUTIONARY MEASURE: Isolate spill or leak area for at least 50 meters (150 feet) in all directions.

LARGE SPILL: Consider initial downwind evacuation for at least 300 meters (1000 feet).

FIRE: If tank, rail tank car or highway tank is involved in a fire, ISOLATE for 800 meters (1/2 mile) in all directions; also, consider initial evacuation for 800 meters (1/2 mile) in all directions. (ERG, 2024)

Section 7. Handling and Storage

Excerpt from ERG Guide 130 [Flammable Liquids (Water-Immiscible / Noxious)]:

ELIMINATE all ignition sources (no smoking, flares, sparks or flames) from immediate area. All equipment used when handling the product must be grounded. Do not touch or walk through spilled material. Stop leak if you can do it without risk. Prevent entry into waterways, sewers, basements or confined areas. A vapor-suppressing foam may be used to reduce vapors. Absorb or cover with dry earth, sand or other non-combustible material and transfer to containers. Use clean, non-sparking tools to collect absorbed material.

LARGE SPILL: Dike far ahead of liquid spill for later disposal. Water spray may reduce vapor, but may not prevent ignition in closed spaces. (ERG, 2024)

Section 8. Exposure Controls / Personal Protection

Wear self-contained positive pressure breathing apparatus and full protective clothing. (USCG, 1999)

Section 9. Physical and Chemical Properties

2-fluorotoluene appears as a colorless liquid with an aromatic odor. May sink or float on water. (USCG, 1999)
