Basic Computer Skills Understanding of Fire Growth

Learning Objectives:

Evaluate Egress Time Understand Time of Survivability in a fire

Technical Notes:

DOS based, public domain software is available from NIST (www.nist.gov) Building and Fire Research Laboratory. The assignment Word document is at the OSU URL

Text of Learning Exercise:

Computer Models Laboratory Â– Egress Simulation Building Construction In this lab you will use the FPE Tools software to evaluate some egress and tenability conditions for hypothetical situations. You will work in teams of 2 members.

This software is public domain and can be copied freely.

You will need to keep track of your data and write a summary report for 4, 5 and 7 to be turned in __________________________. Procedure:

1. The program you will need is FPE Tools. The file fpetool.exe should be in the directory FPETOOL on the CD or available at http://www.bfrl.nist.gov/866/fmabbs.html#FPETOOL 2. download or install the program 3. Start FPETool 4. Select ASETBX from Fireform on the menu bar and perform the calculations based on a moderate fire in a 12 x 12 room with a 10-foot ceiling. Explain what this shows you in terms of the tenability of the space. Hopw long does a person have to get out of the space. Write a report of your findings.

5. Select egress time calculations. Use defaults values where shown and consider all evacuees able for the first set of calculations.

a. Consider 250 persons in a space with and a horizontal egress distance of 145 feet. 2 door leaves. 18 feet of vertical distance 2 stairs that are 32 inches wide. b. Same pr
oblem but use only 1 door and 1 stair c. Same problem as a. but the stairs are now changed to be 44 inches wide d. Same problem as a. but evacuees are not able and their speed is 50% of an able person. e. Same problem as a. but there are 400 persons.

6. Evaluate the parameters for the 3rd Floor of the Engineering South assuming 180 persons in room 317 for an FPS meeting. (Estimate distance based on pacing off the distance and counting the stairs). Begin at the door to the room. Consider the end of the exit discharge to be the sidewalk bike lane/sidewalk in the mall between Engineering South and the Advanced Technology Research Center

7. Time the length of time it takes a member ofyour group to walk briskly from the door of 317 to the sidewalk area. Compare the timed result with your calculations in the computer program (6).

Write a report (1 report per group) on your findings.
