| Shoring | General term used for lengths of timber, screw jacks, hydraulic and pneumatic jacks, and other devices that can be used as temporary support for formwork or structural components or used to hold sheeting against trench walls. Individual supports are called shores, cross braces, and struts. (Page 338) |
| Cribbing | Varying lengths of hardwood, usually 4x4 inch or larger, used to stabilize vehicles and collapsed buildings during extrication incidents. (Page 339) |
| Block & Tackle | Series of pulleys (sheaves) contained within a wood or metal frame. They are used with rope to provide a mechanical advantage for pulling operations. (Page 346) |
| Triage | System used for sorting and classifying accident casualties to determine the priority for medical treatment and transportation. (Page 350) |
| Stabilization | Process of providing additional support to key places between an object of entrapment and the ground or other solid anchor points to prevent unwanted movement. (Page 350) |

Useful for nailing wedges and other wooden components of shoring systems into place. (Page 340-341) |
| List four safety rules when using pneumatic lifting bags. | Any 4 of the following: -Plan operation before starting -Be familiar with the equipment, its operation principles and methods, and its capabilities and limitations. -Follow the manufacturer's recommendations for the specific systems used -All components should be kept in good operation condition with all sagety seals in place -Have available an adequate air supply and sufficient cribbing before beginning operations -Bags should be positioned on or against a solid surface -Bags should be protected from sharp objects during inflation. -Bags should be inflated slowly and monitored continually for any shifting. -Never work under a load supported only by airbags. -Continuously shore up with enough cribbing to adequately support the load in case of bag failure. Lift an inch, crib an inch. -When box cribbing is used, the top layer should be solid -Bags should not contact materials hotter than 220 degrees F. -Bags should never be stacked more than 2 high. Place the smaller bag on top, and inflate the bottom bag first. (Page 344-345) |

| Discuss maintaining emergency power equipment | -Review the manufacturer's service manual for specific directions. Gather the tools and service parts needed to perform the service and maintenance items. -Carefully inspect the spark plug for damage, any visible corrosion, carbon accumulation or cracks in the porcelain. Check to make sure the spark plug wire is tight. -If needed, replace the spark plug, ensuring proper gap prior to installation. -Check equipment carburetor and identify any signs of leaks -Check fuel level and fill with fuel as necessary -Discard old fuel (older than 3 weeks) and replace with new fuel. May not be necessary if fuel stabilizer is used. -Check oil level and replenish oil as needed -Start the generator and run any test identified in the users manual (Page 334) |

| Discuss stabilizing vehicles involved in a vehicle incident | -Vehicles need to be stabilized vertically and horizontally, preventing movement in any direction. -After vehicle is stabilized, shut down the electrical power within the vehicle. Before killing the power, roll down any power windows, unlock power doors, and move power seats if needed. -Use extra caution when disconnecting the power supply on hybrid vehicles. -Never place any body part under the vehicle while stabilization is in progress. (Page 350-353) |

| Describe basic actions taken for patient management | -Choose the easiest route to gain access -At least one rescuer with appropriate training should enter the vehicle to begin patient stabilization, assessment, and treatment and to protect the patient while extrication is in progress. (Page 355-356) |
| Describe patient removal | -Vehicle is removed from around the patient. The patient is not removed from the vehicle. -Cover any sharp edges -Make sure openings are big enough to safely extricate the patient (Page 356) |
| Discuss removing glass from vehicles | Laminated glass: the best method to remove laminated glass is with a saw. Common tools used are: air chisel, axe, reciprocating saw, handsaw with a coarse blade, hay hook, windshield saw Tempered glass: can easily be broken by either striking them with a sharp, pointed object in the lower corner of the window or by using a spring-loaded center punch. Applying a layer of spray adhesive or duct tape can ease in the removal of the glass. (Page 357-358) |
| Explain considerations when removing vehicle roof and doors | -Roof removal can either be done by cutting the A, B, and C posts and removing the roof entirely or by cutting only the front posts, cutting relief notches and folding the roof back over the trunk. -Vehicles should be well supported before removing the roof -Doors can be opened from the handle side or be removed completely by inserting the spreader into the crack on the hinge side -Cutting hinges, breaking the latch mechanism (Nader pin) or compromising door locks are other methods to gain access through a door (Page 359-360) |
| Describe common patterns of structural collapse | Pancake collapse: Occurs when simultaneous failure of exterior walls results in the upper floors and the rood collapsing on top of each other such as in a stack of pancakes V-shaped collapse: Occurs when the outer walls remain intact and the upper floors and/or roof structure fail in the middle Lean-to collapse: Occurs when one outer wall fails while the opposite wall remains intact A-frame collapse: Occurs when the floor and/or roof assemblies on both sides of a center wall collapse into what might be seen as opposing lean-to collapses Cantilever collapse: Occurs when one or more walls of a multistory building collapse, leaving the floors attached to and supported by the remaining walls. (Page 362-364) |
