Search and Rescue Safety
Contra Costa County CERT - Unit 5 3/31/2017 Search and Rescue Safety Always have a whistle! The following “Emergency Alerting System” is to be used in the event of problems at the site: Evacuate - 3 short blasts (1 second each) Out – Out - Out Drop everything and get out now! Cease Operations - 1 long blast (3 seconds duration) Quiet Stop what you’re doing and wait for instructions Resume Operations -1 long and 1 short blast Oooh - Kay This is the FEMA US&R Standard Rev. 18 August 2011 10

Contra Costa County CERT - Unit 5 3/31/2017 Search and Rescue Safety Earthquakes aftershocks Severe after shocks following a major earthquake are common and can create additional injuries and fatalities Unstable structures including bridges, overpasses, high rises, homes and water towers may suffer further collapse as a result of after shocks First responders must be constantly aware that they may be affected by such events and take necessary precautions while conducting their operations. Many injuries and deaths of first responders could be prevented if more precautions against additional shock waves were taken Rev. 18 August 2011 11

Contra Costa County CERT - Unit 5 3/31/2017 Search and Rescue Safety With the constant threat of terrorist attacks it is essential that response teams pay special attention to a very new and potentially deadly threat Everyone has to heighten their awareness of their surroundings Secondary explosions are becoming common techniques used to cause serious injury and possibly mass death for response teams There are no second chances when explosions are used for this purpose After an explosion it is safe to assume that a secondary devise is involved, unless proven otherwise Rev. 18 August 2011 12

Conducting Search Operations
Pancake Voids: Pancake voids (most common in pre-1933 buildings) are small voids throughout a structure that are created by weakening or destruction of load-bearing walls and the resulting collapse of floors onto each other. Lean-To Voids: Lean-to voids are created when a collapsed wall or floor is resting against an outside wall, creating a pocket of space. “V” Voids: These voids are created by a “V” collapse of a floor or wall: the middle collapses and the ends lean against the outside walls..

3/31/2017 Planning / Staging Conduct a size-up of the scene Have one person in charge and formulate a plan of action Gather necessary materials for leveraging (lifting) and cribbing operations Rev. 18 August 2011 74

Leveraging And Cribbing
When a large object such as a collapsed wall or heavy debris needs to be moved in order to free victims, leverage and cribbing may be used. Leverage is obtained by wedging a lever (pole or other long object) under the object that needs to be moved with a stationary object underneath it to act as a fulcrum. When the lever is forced down over the fulcrum, greater force is obtained to lift the object. A crib is a framework of wooden, plastic or metal bars used for support or strengthening. Box cribbing means arranging pairs of wood pieces alternately to form a stable rectangle. In a disaster situation, debris may be available to use for cribbing.

3/31/2017 Leveraging Lever Defined: A rigid bar, either straight or bent, that is free to move on a fixed point called a fulcrum A lever works by transferring a force from one place to another while at the same time changing the direction of the force Clallam County Technical Rescue Team photo Rev. 18 August 2011 76

3/31/2017 Cribbing Video Rev. 18 August 2011 77

3/31/2017 Leveraging (Lifting) Lift an inch, Crib an inch Stabilize the object to be lifted Initiate the lift using the lever and fulcrum for mechanical advantage Have someone available to handle the victim As the object is lifted, add cribbing as needed; build on the foundation of the box crib When the object is adequately supported, the victim may be removed Rev. 18 August 2011 78

Cribbing 3/31/2017 24,000 lbs. total if load is supported by 4 joints 54,000 lbs. total if load is supported by 9 joints 4” x 4” wood 6,000 lbs. at each joint Rev. 18 August 2011 79

3/31/2017 Cribbing Wood fails at cut ends first Overlap ends by width of member – 4x4 = 3.5” overlap Don’t crib higher than three times the width of the crib Load needs to be supported with wood-to-wood contact all the way to the ground Rev. 18 August 2011 80

Cribbing 3/31/2017 Shims are used to match the angle of a surface Shims balance the load by ensuring even contact Copyright Marin Sheriff’s Search & Rescue Rev. 18 August 2011 81

3/31/2017 Cribbing Wedges are used as variable height crib members Wedges are inserted as Married Pairs Wedges can be used as Inclined Planes to prevent sliding movement Single wedges can be used for temporary stabilization until flat pieces can be inserted Rev. 18 August 2011 82
