All of the above
There are four classes of fires. Class C fires are:
Fires in wiring, fuse boxes, energized electrical equipment, computers, and other electrical sources.
MIG and TIG welding incorporate a gas in the welding process. The gas introduces what hazard to the
work?
Ashpyxiation
Hazard determination in welding is accomplished by evaluating the:
Welding method and materials to be welded along with the physical location.
The potential difference between two points in an electrical circuit is measured in:
Volts
The unit of measure of electrical current is:
Amps
A unit of measure of power is:
Watts
The method commonly used for control of hazardous energy sources is referred to as:
LOTO (Lock out/Tag out)
A supported scaffold consisting of a platform(s) resting on bearers, the outside ends of which are
supported on
runners secured to a single row of posts or uprights, and the inner ends of which are supported on or in
a structure or building wall is a:
Pole Scaffold
A rooftop supported scaffold consisting of a platform resting on angular-shaped supports is a:
,Roof Bracket Scaffold
A supported or suspended scaffold consisting of a platform(s) supported by tubing, erected with
coupling devices
connecting uprights, braces, bearers, and runners is a:
Tube and Coupler Scaffold
A supported scaffold consisting of a platform supported by vertical poles and movable support brackets
is a:
Pump Jack Scaffold
A supported scaffold consisting of a platform resting on brackets attached to ladders is a:
Ladder Jack Scaffold
A scaffold consisting of a platform(s) supported on fabricated end frames with integral posts, horizontal
bearers, and intermediate members is a:
Fabricated Frame Scaffold
Construction workers who will work with and on scaffolds must be trained. Retraining is required when:
Changes at the work site create conditions that change the hazards and risks
Cranes require frequent and periodic inspections. Frequent inspections required for cranes include:
Daily pre-operational site and crane inspection, pre-start-up inspection and crane operation inspection.
A total system of support for freshly placed or partially cured concrete, including the mold or sheeting
that is in contact with the concrete as well as all supporting members including shores, hardware,
braces, and related hardware is a:
Formwork
Lifting vertically a slab (or group of slabs) from one location to another during a lift-slab construction
operation is a:
Jacking operation
A method of concrete construction in which floor and roof slabs are cast on or at ground level and, using
jacks, are moved into position is a:
Lift Slab Method
Concrete members (such as walls, panels, slabs, columns, and beams) that have been formed, cast, and
cured prior to final placement in a structure are:
Precast Concrete
The construction operation in which shoring equipment is placed, as the original forms and shores are
removed in order to support partially cured concrete and construction loads is called:
, Reshoring
Crossed bridging that is bolted to a steel joist or joists is:
Bolted Diagonal Bridging
Steel joist bridging connected to a bridging terminus point is:
Anchored Bridging
An entity that has the overall responsibility for the construction of the project-its planning, quality, and
completion is the:
Controlling Contractor
The individual responsible for the design of structural steel framing and whose seal appears on the
structural contract documents in the:
Project Structural Engineer
Members pre-stressed before the application of the superimposed loads and having all cables or
tendons fully bonded to the concrete or grouted within ducts.
Category 1
As Category 1, but having the tendons left ungrouted. This type of construction can sometimes be
recognized from the access points which may have been provided for inspection of the cables and
anchors. More
recently, unbonded tendons have been used in the construction of beams, slabs, and other member;
these tendons are protected by grease and surrounded by plastic sheathing, instead of the usual metal
duct.
Category 2
Members that are pre-stressed progressively as the building construction proceeds and the dead load
increases, using bonded tendons, as Category 1.
Category 3
As Category 3, but using unbonded tendons, as Category 2.
Category 4
The action taken to free equipment from any electric connection and/or electric charge is called:
De-energize.
The blasting operation by which the rock formation is dislodged from its natural location is called:
Primary Blasting
The reduction of oversize material by the use of explosives to the dimension required for handling is
called:
