contact lenses and open eyes wide apart. To hospital or eye specialist.
Ingestion NEVER MAKE AN UNCONSCIOUS PERSON VOMIT OR DRINK FLUIDS! Do
not induce vomiting. Rinse mouth with water. Contact physician if larger
quantity has been consumed. Get medical attention if any discomfort
continues.
4.2. Most important symptoms and effects, both acute and delayed

Methyl ethyl ketone (MEK) Page 3 of 8
5.1. Extinguishing media
Suitable extinguishing media Extinguish with alcohol-resistant foam, carbon dioxide, dry powder or water
fog.
Improper extinguishing media Do not use water jet as an extinguisher, as this will spread the fire.

5.3. Advice for firefighters
Fire fighting procedures No specific fire fighting procedure given.

SECTION 6: Accidental release measures

6.1. Personal precautions, protective equipment and emergency procedures
Personal protection measures Ensure suitable personal protection (including respiratory protection) during
removal of spillages in a confined area. Ventilate well. Stop leak if possible
without risk. Avoid contact with skin and eyes. Do not breathe vapour. For
personal protection, see section 8.
6.2. Environmental precautions
Environmental precautionary Avoid discharge into drains, water courses or onto the ground.
measures
6.3. Methods and material for containment and cleaning up
