Why repeat backs when instructions are being given? To ensure that there are no misunderstandings, no mistakes. To ensure that everyone is on the same page and everyone knows what needs to be done. Here is an excerpt from Dr. Richard Gasaway’s book Situational Awareness for Emergency Response
COMMAND: “Engine 1, I want you to advance an inch-and-three quarter line through the back door to the second floor and conduct a search and attack.”
ENGINE 1: “Copy. An inch-and-three quarter line, through the front door to the second floor for attack and search.”
Do you know notice the error there? What might have happened if the crew of Engine 1 did not repeat back the message from command and continued with what they thought to be the proper course of action? The excerpt continues….
COMMAND: “Negative. I want the line through the back door.”
ENGINE 1: Copy. Line through the back door.
Proper communication in an emergency situation, heck any situation, is key to a good and safe outcome.
Remember: Stay Alert & Stay Safe. Never stop learning and Never stop training.
