- Waking WatchGeneral Fire SafetyA waking watch is a temporary fire safety measure involving trained personnel patrolling a building continuously to detect fire and alert residents — typically imposed on multi-occupied residential buildings where cladding or passive fire protection defects pose an unacceptable life risk. It is an interim measure pending permanent remediation and can be replaced by a common fire alarm system once BS 5839-1 compliance is confirmed.View definition
- Evacuation Alert SystemGeneral Fire SafetyAn evacuation alert system (EAS) is an electronic system installed in higher-risk residential buildings that enables the fire and rescue service to issue targeted floor-by-floor evacuation alerts, directing residents to evacuate when the stay-put strategy is no longer safe. Required under the Fire Safety (England) Regulations 2022 for all residential buildings above 18 metres, EAS must comply with BS 8629 and be regularly tested and maintained.View definition
