Fire Stops Penetrations Through Membrane (i.e., metal outlet box) Warnings Firestops are tested as an assembly Tested as an assembly If not installed per manufactures specifications the testing is invalid Installers may be held personally liable Substitute materials aren’t part of the assembly Types of Products Mechanical Mortar/Compounds

Fire Stops Types of Products Composite Sheets Collar/devices Blankets Caulks/sealants Putty Wrap strips Pillows/bags Sprays

Fire Stops Fire Stop Material Traits Endothermic This trait allows a fire stopping material to emit water vapor as it burns to cool the material prevent the transfer of heat to the far side of the firewall Intumescent Swells when heated Fills spaces around or in a penetration Ablative Develops a hard covering when heated - important in resisting hose sprays of pressurized water

Fire Stops Selecting Firestop Materials/Systems Selection Criteria Local authorities Qualification Testing Installation efficiency Maintenance convenience Future cable changes Some Electrical Apparatus are Fire-rated i.e., boxes, junction boxes, breaker panels, fixtures, and poke-thrus Firestop all non-rated apparatus

Fire Stops Selecting Firestop Assembly Identify type of barrier to be penetrated Floors, Walls, combinations of walls and floors Construction of barrier Concrete drywall wood etc. Penetrating items Size/shape of Opening Orientation of penetrating items to the opening Water exposure Movement/vibration of the penetrating items Required ratings F, H, and T
