Ground, Weather and Light Guidance

Have you carried out an inspection of the whole playing area, at no faster than a walking pace, including the area immediately beyond the boundary where fielders may field or catch the ball?
Do the bowlers have reasonable footholds – i.e., are they able to bowl without slipping – this must include the full run up, to the point after delivery of the ball?
Do all of the fielders have the power of free movement around the ground – can they can move, turn and run at full pace, without slipping?
Do the batsmen have the ability to play their shots and run freely between the wickets without slipping, both when they set off and in the action of turning?
Are you satisfied that there is no surface water and no standing water (water visible around the feet when pressed into the ground) in the playing area within 30 yards of the pitch, or on the square? If further away, would they be so slippery as to be a danger?
In your opinion is there sufficiently good visibility to enable you to conclude that you, the batsmen, and fielders will be able to see the ball (taking into account its pace) clearly enough to be safe?
Are you satisfied that after pitching the ball does not bounce unpredictably or steeply or in a way that poses a danger to the striker or the wicket-keeper standing up?
Are you satisfied that none of the conditions pose an actual and foreseeable risk to the safety of any player or umpire?
Does the other umpire (if present) agree with your answers?

If either umpire believe that conditions are not acceptable or safe then match must be suspended
