The (S) factor relates to the quality of safety management at a ground. (P) and (S) factors and indicative questions should be reviewed annually. They should also take place whenever there is any physical alteration to the ground or a change in the nature of the sport or event being staged. Where a safety certificate is in force any reassessment should be ratified by the local authority.
