        1.    One of the most important attributes a search and rescue specialist can have is a ____________ attitude toward safety.

                       a.   Disinterested

                        b.   Positive    

            c.      Non-committal

            d.      Cautious

         2.   Brittle types of material behavior can be best described as

            a.   Bend but don't break

                        b.   Sudden failure

            c.   Very high strength

            e.      All of the above

         3.   Ductile type material behavior can best be described as

                  a.   Bend but don't break

            b.   Sudden failure

            c.   Very high strength

            d.      All of the above

        4.    Based on damage and collapse patterns seen in previous earthquakes, buildings can usually be divided into which of the following five general categories:

            a.   Wood, tilt‑up, steel, concrete, URM

                  b.   Light frame, heavy wall, heavy floor, precast concrete, diagonally braced  steel frame

            c.   URM, Tilt‑up, concrete, precast concrete, Post-tensioned concrete

            d.   Light frame, light steel, mobile homes, unengineered       building

        5.    A Structure/Hazard marking on a building showing a box with one diagonal line means that

            a.   Searchers have entered the building

            b.   Structure is safe for occupancy

                  c.   Structure is significantly damaged, some areas may be relatively safe, but other areas may need shoring, bracing, or removals of hazards

            d.      Structure is not safe for rescue operations

        6.        You come across a structure with a paint marking made (by a US&R Task Force member or other qualified agent) showing an X inside a two-foot square box.  What does that mean to you?

            a.   The structure is safe to enter for search and rescue

                  b.   The structure is currently not safe to enter for search and rescue

            c.   The structure is significantly damaged, some areas may be safe with others areas may require shoring and bracing.

            d.      There are Hazardous Materials (HAZMAT) in the structure

       7.    How can a structural hazard be safely mitigated?

                        a.   Avoid it

            b.   Remove it

            c.   Shore it

            d.      All the above

       8.    Signs of possible imminent secondary collapse are

                        a.   Shifting debris

            b.   Sliding plaster

            c.   Creaking, cracking and groaning sounds

            d.      All of the above

       9.    Cement and concrete are the same thing?

                        a.   True

                  b.   False

       10.  Cast in place concrete can best be described as                

                  a.   Concrete which is molded in the location in which is expected to remain.

            b.   High tensile strength steel strands or bars are encased in tubing or wrapped to prevent any adhesion between steel and concrete.  Steel is stretched and anchored.

            c.   Concrete that has been cast at a location other than the place it is to remain.

            d.      A composite material of steel and concrete.

       11.  Precast concrete can best be described as        

                        a.   Concrete which is molded in the location in which is expected to remain.

            b.   High tensile strength steel strands or bars are encased in tubing or wrapped to prevent any adhesion between steel and concrete.  Steel is stretched and anchored.

                  c.   Concrete that has been cast at a location other than the place it is to remain.

            d.      A composite material of steel and concrete.

       12.  Reinforced concrete can best be described as             

            a.   Concrete which is molded in the location in which is expected to remain.

            b.   High tensile strength steel strands or bars are encased in tubing or wrapped to prevent any adhesion between steel and concrete.  Steel is stretched and anchored.

            c.   Concrete that has been cast at a location other than the place it is to remain.

            d.     A composite material of steel and concrete.

       13.  Post tensioned concrete can best be described as      

            a.   Concrete which is molded in the location in which is expected to remain.

                  b.   High tensile strength steel strands or bars are encased in a casing or wrapped to prevent any adhesion between steel and concrete.  After concrete is sufficiently cured, steel is stretched and anchored.

            c.   Concrete that has been cast at a location other than the place it is to remain.

            d.      A composite material of steel and concrete.

       14. The three basic forces that rescue team members must understand and manipulate when breaching and breaking concrete are.

            a.      , compression and gravity

            b.     Tension, shear and compression

            c.      Tension, shear and pressure

            d.      Tension, compression and vector

       15.  Tension stress is best described as:

                        a.       Stretching or pulling force

            b.       Pressure applied to an object; smashing force

            c.        Cutting or lateral force

            d.       Bending or pushing force
