Which CSI MasterFormat Division would contain specifications for fire-stopping and firesafing materials?
Correct Answer
B) Division 07 - Thermal and Moisture Protection
Fire-stopping and firesafing materials are typically specified in Division 07 - Thermal and Moisture Protection, as they relate to sealing and protecting building envelope penetrations.
Why This Is the Correct Answer
Division 07 - Thermal and Moisture Protection is the correct classification for fire-stopping and firesafing materials because these products primarily function to seal penetrations in fire-rated assemblies and maintain the building envelope's integrity. Fire-stopping materials prevent the passage of fire, smoke, and gases through openings in walls, floors, and ceilings, which directly relates to thermal protection and moisture barrier functions. While these materials have fire protection properties, their primary specification purpose is sealing and protecting building envelope penetrations, making Division 07 the appropriate classification.
Why the Other Options Are Wrong
Option A: Division 21 - Fire Suppression
Division 21 - Fire Suppression covers active fire protection systems like sprinklers, standpipes, and fire pumps that actively suppress or extinguish fires, not passive fire protection materials that seal penetrations.
Option C: Division 03 - Concrete
Division 03 - Concrete covers concrete materials, reinforcement, and concrete construction methods, which is unrelated to fire-stopping sealants and materials.
Option D: Division 28 - Electronic Safety and Security
Division 28 - Electronic Safety and Security deals with electronic systems such as fire alarm systems, security systems, and access controls, not the physical materials used for fire-stopping.
Memory Technique
Think 'STOP the THERMAL transfer' - fire-STOPping materials prevent THERMAL transfer through penetrations, so they belong in Division 07 Thermal and Moisture Protection.
Reference Hint
CSI MasterFormat Division listings in construction specifications reference materials or Florida Building Code Chapter 7 for fire-resistance requirements
