Answer 1

4 hour wall, 3 hour door/frame

Question 2

Fire rating of vertical means of egress

Answer 2

2 hour wall, 90 minute door/frame

Question 3

Fire rating between different occupancies

Answer 3

1 hour wall, 1 hour door/frame

Question 4

Fire rating at corridor

Answer 4

1 hour wall, 45 minute door

Question 5

Fire rating at exterior wall with EXTREME potential for fire exposure

Answer 5

2 hour wall, 90 minute door/frame

Question 6

Fire rating at exterior wall with MODERATE potential for fire exposure

Answer 6

1 hour wall, 45 minute door/frame

Question 7

Fire rating at corridor where smoke and draft control are required

Answer 7

1 hour wall, 20 minute door/frame

Question 8

Max vertical rise of stairs before you need a landing

Answer 8

12’

Question 9

Minimum stair and landing width

Answer 9

44”. 48” required for accessible means of egress in unsprinklered buildng. 36” if less than 50 people. Greater than 48” using multiplier for high occupant load.

Question 10

Area of refuge size

Answer 10

30”x48”

Question 11

How much can doors swing into the path of travel?

Answer 11

No more than 7” into required width when fully open. Can’t reduce width by 1/2 at any time when door is in open position.

Question 12

Max cross slope for an ADA ramp

Answer 12

1:48 or 2%

Question 13

Max ramp rise

Answer 13

30” without landing

Question 14

Ramp landing length x width

Answer 14

36” x 60” unless turning: 60x60

Need landing at bottom, middle and top

Question 15

Fire lane requirements

Answer 15

20' wide
10' away from building overhangs
Outside radius of turns: 54'
Inside radius of turns: 30'
Weight to carry: 35 tons

Question 16

3 parts of egress

Answer 16

Exit Access, Exit, and Exit Discharge

Question 17

When does an exit need to be pressurized?

Answer 17

“smoke proof” If building is 75’ or more above grade and/or an underground building (harder to get out of building)

Question 18

Minimum ceiling height

Answer 18

6’-8” for no more than half the space

Question 19

IBC code section for occupant load factors. Round up or down?

Answer 19

1004. Round up so egress is sized for the fraction of the person.

Question 20

IBC code section for fire separation of occupancies

Answer 20

508

Question 21

IBC code section for fire resistive classifications

Answer 21

601

Question 22

Calculating ramp slopes

Answer 22

1:12 slope so multiply:
Height (ft) you need to climb x 12 = Length (ft) of ramp
Add length of landings (60”). Include one per 30” of rise. Need landing at bottom and top as well.
