After a number of firefighter deaths at notable fires in the 1990s (Gillender street in Bow, East London [1991] and the Sun Valley poultry factory fire in Hereford [1993]), coupled with the publishing of the Fennell Report into the King's Cross fire of 1987, WYFRS developed an incident command policy that encompassed an at-incident dynamic risk assessment and an organisational structure assessment for major fires. This policy was driven forward by central government and after some refinement was adopted in 1999.
