All members have additional fire rated coding/cover such as she rock, or spray on fireproofing. Extends the fire resistance rating of structure members by at least an hour.

Answer 5

Group a

Tripled at multistory.

Question 9

If more than___of a building perimeter walls face public way/open space, and increase in area is granted her a formula

Answer 9

1/4 faces open space

Question 10

If a building is divided by firewalls and to me it’s required fire resistance rating’s, each portion of the building that is separated from the remainder of the building by firewalls can be considered:

Answer 10

Separate building, for purposes of calculating allowable area.

Basically at a building can be a lot bigger than the IBC table would normally allow.

Question 11

Exit
Exit discharge

Answer 11

Building egress

Question 12

Answer 13

Exit

Question 14

The portion of the means of egress system between the exit and a public right-of-way.

Answer 14

Exit Discharge

Question 15

Are no longer permitted or usually permitted because smoke rising from lower floors eliminates the safety of using them

Answer 16

Horizontal exits

Question 17

Similar to an exit, but horizontal, and leads to the exit discharge

Answer 17

Exit passageway

Question 18

Egress is regulated by:

Answer 18

Number of occupants,

Function of space

Question 19

Aisles, stairs, and doors are sized by multiplying the occupant load by :

Answer 19

The Egress Widths per Occupant Table per the IBC

Question 20

The minimum exit with in inches is determined by multiplying the total flow in the passage (total occupant load) by:

Answer 20

0. 2 in sprinkler buildings
1. 3 in non-sprinklers.

Can’t be less than 44 inches.

Question 21

Generally at least two means of egress are required unless:

Answer 21

There are more than 500 occupants,

Then more required.

Also number of exits may be influenced by travel distance, or length of the common path of travel to an exit.
