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

Search and Rescue Safety 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

Search and Rescue Safety 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..

Leveraging and Cribbing Operations Contra Costa County CERT - Unit 5 3/31/2017 Leveraging and Cribbing Operations ICS-US&R-120-1 Rev. 18 August 2011 73

Contra Costa County CERT - Unit 5 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.

Contra Costa County CERT - Unit 5 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
