New York City Site Safety Manager (SSM) Certification Practice Test

During demolition, visibility and protection of the fire water supply are essential. The requirement is to clearly identify non-automatic and Siamese hose connections so crews can find them quickly and avoid accidental damage or misconnection. Marking these connections with a metal sign that reads “Sprinkler Siamese Connection” plus a red-light bulb at night ensures high visibility both day and night, which is crucial when heavy activity and equipment are nearby. Draining the system would remove protection and create downtime, leaving it untouched risks misidentification and tampering, and painting the system red addresses appearance but not the need for explicit identification and illumination.
