COMMUNICATIONS is CRITICAL when relaying information….. We responded on an EMS run at 0315 hrs this past Sunday morning on an exit ramp of the New York State Thruway. Our dispatcher informed us that the Police on the scene wanted us to enter the exit ramp driving against traffic to expedite our response. They would stop traffic when we were ready to enter. As we arrived at the ramp, we advised our dispatcher, who in turn told us that he had verified that it was safe for us to proceed. We then slowly began our entry onto the ramp. The ramp in question is t-shaped with a totally blind curve and two off ramps. The Close Call: The incident was not where it was reported to be. The ramp was closed by Police, but not where it was reportedly closed. We did not experience any near miss, but could have very easily. This ramp is heavily traveled by all types of vehicles, including 18-wheelers, which we could have met head-on. Fortunately, the time and day of the week lessened the traffic flow. Communication was the big problem here. Our dispatcher received his information from County Fire Control, who received their information from the PD dispatcher, who had received his information from the Police on the scene. Like the children’s game, “Telephone,” whispering around a circle. By the time we received the information it was incorrect; and we had no way to contact the on scene Police directly. No common frequency between Police and Fire. The Police Officer on the scene advised me that he had been very specific when advising his dispatcher of the location.
