4. FIRST AID MEASURES
General: If exposed or concerned, get medical attention or advice and show this safety data
sheet to doctor in attendance.
Eye contact: Check for and remove any contact lenses. Immediately flush eyes with running water
for at least 5 minutes, keeping eyelids open. Get medical attention if redness or
irritation persists.
Skin contact: Remove contaminated clothing and shoes. Wash skin with soap and water. Get
medical attention if irritation symptoms occur. High pressure injection under skin is a
medical emergency.
Inhalation: Move exposed person to fresh air. If breathing is irregular or stopped, give artificial
respiration. Get medical attention if irritation develops and persists.
Ingestion: Do not induce vomiting and give large quantities of water. Get medical attention.
Special treatment:
Notes to physician: Treat symptomatically.
5. FIRE-FIGHTING MEASURES
Suitable media: Use dry chemical, CO2, water spray (fog) or foam.
Not suitable: Do not use water jet.
Combustion products: Carbon monoxide, carbon dioxide, products of incomplete
hydrocarbon combustion, nitrogen oxides (NOx).
Special protective equipment Fire-fighters should wear appropriate protective equipment and self-
for fire-fighters: contained breathing apparatus with a full face-piece operated in
positive pressure mode.
