Risks and prevention — Fire protection
Sprinkler and suppression-system installation involves work at height, heavy pipe handling, and brazing/welding. CSTC 3.14.1 requires fire precautions near combustibles — not a named “hot-work permit” in the Code.
Hydrostatic tests put the system under high pressure. Fittings must be checked, the area barricaded, and workers cleared during pressurization. Water-filled pipes add significant load to the structure, which must be verified by the engineer.
