Dear Mr. Karner: This responds to your October 1, 1981, letter asking whether it woul be permissible to attach a label to a door stating 'To Open Door in Emergency Pull Down'. You indicate that the door is not an emergency door in compliance with Standard No. 217, *Bus Window Retention and Release*. You question whether the addition of the label in conformance to a contract with the Chicago Transit Authority (CTA) would make the door an emergency door that would be required to comply with the standard. The CTA requires that door to be so labelled because it desires the door to be used as a means of escape.; The standard states that buses shall be equipped with a minimum numbe of emergency exits and that all emergency exits shall be labelled properly and comply with the requirements of the standard. One purpose of the standard is to provide sufficient emergency exits. Another purpose is to provide uniform emergency exit markings and operating instructions. You have stated that your vehicle has the requisite number of emergency exits, properly marked, so that the door in question is not required in counting the total number of exits for purposes of complying with the standard.; As you know, not all doors are required to be emergency exits. Fo example, the front entrance door of a vehicle need not be an emergency exit. If it is not labelled an emergency exit, it need not comply with the requirements of the standard relative to emergency exits. Similarly, the door to which you refer need not comply with the emergency exit requirements if it is not labelled as an emergency exit. However, since your proposed label refers to the emergency nature of the door, it appears to place the door within the category of an emergency exit that would be required to comply with the standard. The CTA intends the door to be used as an emergency exit and the label will indicate to riders that the door is suitable for such purposes. You may not, therefore, refer to the door as an emergency door unless the door complies with all of the requirements.; Sincerely, Frank Berndt, Chief Counsel
