Corridor Separation

In this case study we will examine the requirements of the R-2 occupancy (congregate living facility with more than 16 occupants) pertaining to corridor rating and vertical space allowances. All corridors are required to be constructed of fire rated walls with a minimum rating of 30 minutes (1020.1). Also, these “R” occupancies cannot have unprotected 2-story openings (712.1.9, #4). These requirements can be challenging when spacious open designs are desired. Because the opening protectives for these walls can be rated 20-minutes (716.5.3), the McKEON FireFighter® D200 is the perfect solution. Take a look, too, at CASE 9. It is right across the hall!
