3. Cast Iron
4. Metals
5. Concrete
6. Gypsum
7. Plaster on lath
8. Glass
9. Plastic

Question 6

What are 4 types of loads? 14/19

Answer 6

1. Fuel load (The amount of potential fuel available for a fire to burn)
2. Structural load ( forces that work against a structure’s ability ton remain standing)
3. Dead load (The weight of the building and any attached fixtures is referred to as the self-weight or dead load.)
4. Live load (Any load on a structure, other than dead load)
   5 Impact, Static and repeated loads

Question 7

Dead or live loads, whether static, impact or repeated will produce internal forces within structural members.
These loads can produce stresses in a number of direction! Name 3? 14/20

Answer 7

1. Compression loads (loads squeeze an shorten a member.
2. Tensile loads (pull apart or lengthen a member)
3. Shear loads ( cause the planes of the member to slide past on another)

Question 8

Three kinds of loads that exert different internal stresses? ? 14/21

Answer 8

1. Axial
2. Eccentric
3. Torsional

Question 9

Define Party-wall? 14/23

Answer 9

A wall that sits on the property line between two buildings and is shared by both is called a party wall.

Question 10

Define Firewall? 14/23

Answer 10

Self supporting interior wall that extends from the foundation through the roof of the building to a height sufficient to keep fire from jumping the wall and is Fire resistant.

Answer 11

1. Party wall
2. Firewall
3. Fire partition wall

5. Shed
6. Lantern

Question 14

Name 4 roof hazards? 14/30

Answer 14

1. Skylights may be hard to see and may become soft under fire conditions
2. Ventilation could speed up a roof collapse by prividing the fire with more air.
3. An excessive live load can cause collapse (water, manpower, ice)
4. The weight of HVAC systems could also contribute to an early collapse.

2. Vee-shaped
3. A-Frame
4. Pancake
5. Cantilever

Question 16

How big should a collapse zone be? 14/33

Answer 16

one and a half times the size of the building.
