Before the fire return all 3 of us were coughing up a lung. I have seen this before due to the fact the 777 has powerful recirculating fans and the dust and impurities can be blown back up through the radio rack below our feet. Once the event began I never thought about it again since there was no obvious external signs. The air felt and looked clear but we were all hacking away. After we landed I realized that we were more than likely breathing the particles from the ensuing smoke event.
B777 Captain reported temporary health symptoms from 'smoke event.'
