 You have picked me out.
Through a distant shot of a building burning
you have noticed now
that a white cotton shirt is twirling, turning.
In fact I am waving, waving.
The speaker is trapped in the burning building— he is figuratively described as a “distant shot” to emphasize how he is perceived to be very far away. It also reflects the way the disaster was seen by more people through media “shots” than in real life. 
 Note that the second and fourth lines of this stanza end with repeated identical words or  alliterative  related words. Therefore we have ‘burning, burning’ in this line, followed by ‘twirling, turning’ two lines later. This repetitive device is used throughout the poem. These similarly constructed lines are known as  syntactic parallels .The double present participles e.g. ‘bullying, driving’; etc work as a  refrain , providing a hypnotic rhythm and emphasis
