FIS is aware of reports raised through CROSS (Collaborative Reporting for Safer Structures UK) that highlight potential problems that members need to consider regarding passive fire protection implications around cladding and active fire protection implications of sprinklers being deactivated during the construction phase.
The reports can be viewed on the CROSS website using the links below:

Fire barrier requirements in external wall systems | CROSS
Fires involving thermally modified wood | CROSS
Automatic Opening Vents not functional after two cladding remediations | CROSS
Sprinkler system deactivated during construction works | CROSS

CROSS is a confidential reporting system which allows professionals working in the built environment to report on fire and structural safety issues. These are then published anonymously to share lessons learned, create positive change, and improve safety.
