The actual building sire hof the three floors of the Nest Wing) is approximately i9,600 sq. fit., while the allowable area for a Type H-1hr. building is 72,00d sq. fit. (See. attached capes of computer analysis afWest and East Wings.) The meas of the stairs, rest rooms, etc. can not b e deducted from the area of the building. The number of people that mai be in these accessory areas can he deducted from the total number of people calculated fior the building, but the actual sq. ft. area of these accessary areas cannot be deducted from the total building area. it is my understanding that the installation of a sprinkling system ire the West ming is one of the ,AlLCnic7.tc L31dS in }iC>lu CiJilLTciC:t. With thc Izig1i fuel load m -id largc ntunUcr of people in the building, we. would highly encourage you to made the installation of a sprinkling system your highest pri'ority. Note that Table 9A, kine 5 indicates that the West Wing needs to have a Class II Standpipe and hese if it does not have a sprinkling system. 2 --- All EXITS needemergency exit illumination as required in 94UBC Sec. 1012.2 - Separate Sources of -Power.

It mould be beneficial to enlarge Door E I 46A s it more nearly approximates the width of Hallway 146, The size of t��s southwe�� exit system meds -to more nearly approximate the size of the northerly main exit system. I struggle with what to suggest regarding Doors El 50A and E266A that are a part of -the arca Separation Wall separatilia the East and West Wings of the Library. Technically bath doors should swing out in both directions so that people madly exiting either the East Wing or the- West Wing don't get mashed up against a dosed door that only swings toward the exiting crowd. To find out how others have solved this problem, I called 1CB0 Headquarters to ask their experts how they ustially see this type of situation handled. They said they usually gee two separate doors at such locations, with one door marked EXIT which opens outward handling traffic in one direction and a second door (adjacent to the first) that is marked. EXIT an the other side and which opens outward in the other direction fliereby handling traffic in the opposing direction. I think this is the best solution, if you have the room to do it. If you don't have enough room, the door svving �h� way you .ave �t �s probably the best way to �o. i would sill mark tne ciaor as an EXIT for people going from the West Wing to the Easy Wing. Also, be sure there are large handles an the west side of the doors and that the wards "FIRE DOOR - PULL TO OPEN"' are written (in large letters) on the back (west) side of the doors when they are in the cloyed position.. If you can use the two :E.YZT door salution(one door dor each direction) it would be good to put and F 15 EXIT sign in the corridor near the men's rest xoorri (W 14 8) (and an F 8 at the entrance to Room WI 23) and in Corridor W242 (and an F8 at the entrance to Roam W232). If you don't use this solution, it is probably best to leave the advance EXIT signing the may you have shown ii. S --- Sht. E2.

The flash rate shall not exceed two flashes per second (2 Hz) nor be less than one flash every second (I Hz) throughout the listed voltage rage of the appliance. 64n2ml maximum pulse duration shall be 0.2second with percent. The pulse duration i defined as the time interval between initial and final f nth` �f 1 ,percent of maximum l* The light intensity of a pulsed source may be graphed as a bell-shaped cuzve. The duration of thepulse is measured beginning at the point when the upward side of the curve exceeds 10 percent of the maximum inten- sity to the paint where the downward side of the curve drops below 10 percent of the maximum intensity. 6411 The light source calor shatl be clear or nominal white and shall not exceed 1000 candela (cd) effective intensity). Source Untertsity is a measure of the light output of the appliance. The unit of measure is the candela (cd). ('This unit was formerly called "candlepower." There is a one - to -Dile relationship between candela and candlepow�r. } As you move away from any fight source, its zl�umina.- tiOn decreases. Illumination is measured in units of lumens 0M) per square meter (also called ug"), or lumens per square foot. (Formerly; the unit used to describe illumination was the " foot -can.dl e." One foot- candle equals ozie lumen per square foot, One lumen per square meter equals {x.926 foot-candles.) Because strobe lights flash for a very brief ptriod of time, the perceived brightness can vary depending on the actual peak source strength and duration of the flash. One appliance might r. each a beak intensity of 1(]00 candelas in 0.1 seconds while another might reach 750 candelas in Q.2 seconds. Neverthelessthe human eye IIIight perceive both as being equalIv bri'ght- A mathe- matical relationship is used to relate the perceived brightness of a strobe dight to that of a constan�.ly burn- ing light.
