Evolution 34 KO Cutain Deployment Flashcards
How many % decrease in temperatures when the KO curtain is deployed?
1.1
Testing conducted by the FDNY and NIST showed an immediate 50% decrease in temperatures and significant flame reduction when the KO Curtain is deployed. However, there will be an increase in the smoke condition produced by the fire.
What 2 people can order the KO curtain to be deployed?
1.2 Note:
The KO Curtain will ONLY be deployed on orders of the Officer of the first arriving ladder company and/or the Incident Commander.
The firefighters assigned to the floor above will be in a position to provide an accurate description of the effect the wind may have when the door to the fire apartment is opened. These firefighters SOP shall be?
3.2.1
-Force entry to the apartment above the fire.
-Chock open the entrance door to the apartment above.
-Survey and size-up the layout of the apartment above and communicate this information to the officers in the fire apartment.
-Check for any fire venting from the fire apartment and auto-exposing the apartment above.
-A pressurized water extinguisher may be required at the place of deployment in the case of auto exposure. A handline may be required for severe auto exposure.
-If auto exposure is not a problem, open the apartment window in the room over the fire room. Evaluate the wind condition and relay this information to the officers on the fire floor and the IC.
-Prepare the KO Curtain for deployment, and remove any window gates, child guards, blinds, curtains or other obstructions.
-Do not remove or break the deployment window unless absolutely necessary. An intact window will provide protection from auto-exposure, which may
occur due to shifting or gusty winds, allowing fire to intermittently vent from the fire apartment. Once the KO Curtain is deployed, members can expect
that fire will vent from the target window and auto expose the deployment window via the space between the KO Curtain and the building wall.

5.2
The Deployment firefighter must have their facepiece on and full PPE donned when deploying the KO Curtain. This will protect the Deployment firefighter from unexpected auto-exposure which will subject them to fire, smoke and superheated gases.
Should the KO Curtain be deployed from the horizontal or vertical position?
5.4
