Just to add, in our OC, the Essential Services we maintain includes:
Fire sprinklers, Remote Monitoring, Smoke Detectors, Fire Extinguishers, Fire Hoses, Fire Hydrants, Fire Alarm system, Fire Doors, Exit Lighting, Exit Doors, Exit Pathways, Emergency Lighting. And more.
It’s quite a long list, but most of it is simple to test and maintain. Most modern buildings would have similar maintenance obligations today. Even smallish OCs like ours (12 lots).
