## Discrepancy

DURING CLIMB FL260, TURNED ON ENGINE ANTI-ICE, TWO MINUTES LATER EXPERIENCED STRONG CHEMICAL ODOR.  DONNED OXYGEN MASKS.  CHECK OF E/E COMPARTMENTS, GALLEYS, AND LAVATORIES SHOW NO ABNORMALITIES.  CHECK OF COCKPIT LIGHTING AND INSTRUMENTS IS GOOD, CREW REPORTED ODOR DISSIPATED AFTER A FEW MINUTES, NO ODOR IN CABIN REPORTED.   NO ABNORMALITIES FOUND.    SUSPECT SOMETHING IN ATMOSPHERE.  OK TO CONTINUE.
