When making decisions regarding
starting, continuing or resuming play,
the umpires must err on the side of
caution and must prioritise safety over
and above the optimisation of play,
irrespective of the state of the match.
If there is any doubt as to the likely
threat of lightning, the umpires should •
not start or should suspend play; if
play is already suspended, they should
not resume play until they have agreed
that the threat has passed.
•
The following 40/30 protocol should
be considered by the umpires:
•
Play should not start or resume,
or should be suspended and
shelter immediately sought,
when there are 40 seconds
or less between the flash of
lightning and the associated
thunder clap.
It is generally safe to return to
the field of play a minimum of
30 minutes after the final flash
of lightning or clap of thunder
has been seen or heard.
It might be possible to start
or resume play earlier than 30
minutes
