However, the required illumination level is typically only 1 ft-cd, other than "new stairs during conditions of use", which is 10 fc, and only where "continuous illumination" at 1 fc is otherwise required under NFPA 101 (2009, 2015): 7.8. retrieved 8/29/2012, [34] Jinjin Li, Yuhong Liu, Jianbin Luo, Pengxiao Liu, and Chenhui Zhang, "Excellent Lubricating Behavior of Brasenia schreberi Mucilage" Langmuir 2012 28 (20), 7797-7802, [35] Jason R.
