Dear Mr. Brown: This is in reply to your letter of June 21, 1973, requestin clarification of provisions of Motor Vehicle Safety Standard No. 217 dealing with the identification of emergency exits (S5.1.1). You ask whether this paragraph requires in the case of a 66-passenger school bus having a rear emergency exit which is not located in an occupant space, 66 separate labels, assumedly one for each designated seating position. You ask clarification as well for the identification requirements for emergency exits in a 44-passenger bus with one emergency exit in the rear, three push-out windows on one side of the bus, and two on the other, and with each of the five windows contained wholly in one occupant space. You appear to construe S5.5.1 to require a label for the occupant space of each designated seating position in the bus where a release mechanism is not present.; Your interpretation of the standard is not correct, and th requirements do not call for the extensive labeling you suggest. Paragraph S5.5.1 (second sentence) calls only for the placement of a label in occupant space of an *adjacent seat*, when that occupant space does not contain a release mechanism. Adjacent seats are defined in paragraph S4. of the standard as only those designated seating positions within a specified distance from an emergency exit. Thus, a label is required only when the occupant space of a passenger seat does not contain an emergency exit release mechanism and that seat is an adjacent seat as defined in the standard.; In the case of the school bus you describe, there do not appear to b any adjacent seats, and accordingly no emergency exit identification labeling is required in any occupant space. The only labeling required by S5.5.1 would be that required to appear at the exit itself. The same result would appear to be true with respect to the side push-out windows of the 44-passenger bus you describe if the release mechanism for each push-out window is within the occupant space of the adjacent seat. As you did not indicate the configuration of the seating positions at the rear of this bus we cannot provide you an opinion on the identification requirements at that location.; Yours truly, Richard B. Dyson, Assistant Chief Counsel
