Do Awnings Need Fire Rating Ibc

The international code council icc is a non profit organization dedicated to developing model codes and standards used in the design build and compliance process.

Building codes define requirements for fire ratings fire protection egress and accessibility. A building s use and occupancy classification is the category in the ibc that is assigned to each building or portion thereof that reflects unique hazards sanitation egress and other code related parameters associated with that category. This means that wall assemblies including those containing sprayfoam insulation must be tested in accordance with astm e 119 to determine its hourly fire resistance rating to determine if it can be used within a specific building type. These fire resistance requirements range from no required rating to 3 hours.

Then the ibc adjusts the hourly fire resistance ratings depending on the occupancy of the building. The international codes i codes are the widely accepted comprehensive set of model codes used in the us and abroad to help ensure the engineering of safe sustainable affordable and resilient structures. The two main building codes which dictate this are the ibc international building code and the nfpa national fire protection association s codes nfpa 5000 building construction and safety code and nfpa 101 life safety code. Just because certain code verbiage or annex material exists does not mean you as a designer engineer or review authority should forfeit good judgment or common sense.

The room could require a 2 hour rating a 1 hour rating or no fire rating. The fire resistance rating for exterior walls is based on construction type occupancy and fire separation distance as defined in section 6 of the ibc. The best way to answer the question is to review what type of equipment is being installed in the mechanical room then go to the various nfpa or icc standards for the equipment.
