Question 2

What is 'occupancy classification' in building codes?

Accepted Answer

A category that defines the intended use of a building and determines applicable code requirements

Answer

Occupancy classification (e.g., A for Assembly, B for Business, R for Residential) defines a building's use and triggers specific fire safety, egress, and structural requirements.

Question 3

According to ADA standards, the minimum clear width of an accessible route is:

Answer

ADA Standards for Accessible Design require accessible routes to have a minimum clear width of 36 inches, with 60-inch passing spaces where routes are less than 60 inches wide.

Question 4

What does 'fire-resistance rating' of a building element indicate?

Accepted Answer

The duration (in hours) a structural element resists collapse or fire penetration in a standard fire test

Answer

Fire-resistance rating is the time in hours that a building element (wall, column, floor) withstands a standard ASTM E119 fire test before structural failure or heat transmission.

Question 5

The 'means of egress' in building codes consists of how many components?

Accepted Answer

Three: exit access, exit, and exit discharge

Answer

The means of egress system has three parts: exit access (path within the floor to the exit), exit (protected path such as an enclosed stair), and exit discharge (path from exit to public way).
