Q

What is a model code?

A

One that has been written by a group of comprised experts knowledgeable in the field, without reference to any particular geographical area. A primary model code is the International Building Code (IBC) produced by the ICC and first published in 2000.

Q

According to Underwriters Laboratories (UL) what is a classified label?

A

Samples of a product were tested for certain types of uses only. The product must also carry a statement specifying the conditions that were tested for, allowing field inspectors to determine if the product is being used correctly.

Q

66 What is an exit access travel distance?

A

This is the distance an occupant must travel from the most remote point within a building to the entrance of the nearest exit.

28
Q

67 How is minimum exit width calculated?

A

This is calculated by multiplying the occupant load of a space by the appropriate factor given in the building code.

30
Q

69 Within a means of egress system, what are exit access areas?

39
Q

78 Under what conditions would a wood veneer not have to adhere to flame spread requirements?

A

When a wood veneer is less than 0.0036 in (0.9 mm) thick and applied to a noncombustible material, these requirements do not apply.
