Consideration of Protection for Horizontal Fire-Resistance Rated Enclosures

Life safety systems inside a building are the most important part of that building’s design. They need to be protected as such, and as required by the Code. The method of protection, especially horizontal duct runs, should not be deferred during the design because the protection is very difficult. The protection needs to consider the appropriate fire and structural impacts. This is something that should not be left up to the contractor.
