NFPA's Technical Questions Service is meant to provide information on and assistance in accessing and understanding NFPA codes and standards. Any opinion expressed, therefore, is the personal opinion of the responder and does not necessarily represent the official position of the NFPA or its Technical Committees. In addition, responses provided are not intended, nor should they be relied upon, to provide professional consultation or services. As a reminder, the Technical Questions Service should not be used for questions involved in litigation. Answers provided through the Technical Questions Service do not represent the position of NFPA.
