Page "Pole vault" Paragraph 15
from
Wikipedia
If the pole used by the athlete dislodges the bar from the uprights, a foul attempt is ruled, even if the athlete themselves has cleared the height.
The exception to this rule if the vaulter is vaulting outdoors and has made a clear effort to throw the pole back, but the wind has blown the pole into the bar ; this counts as a clearance.
If the pole breaks during the execution of a vault, it is considered an equipment failure and is ruled a non-jump, neither a make nor a miss.
Other types of equipment failure include the standards slipping down or the wind dislodging the bar when no contact was made by the vaulter.
