Signals Passed at Danger Reports and Data

Over the past 20 years, SPAD risk has reduced by well over 90%. However there is no room for complacency and industry continues to monitor and investigate SPADs to ensure the risk is managed.

SPAD Risk Reduction Strategy - Phase 1

In September 2017, RSSB published the first phase of a new SPAD Risk Reduction Strategy which outlines current industry good practice to focus on those areas where the biggest gains can be made to continue to bring the risk down. This is available below to RSSB members and is shared via relevant events, cross-industry groups and local operational interest groups.
