NSI Technical Bulletin 0014 provides guidance on the implementation of BS 8406:2009, the updated British Standard for event stewarding and crowd safety, which supersedes the 2003 edition. The bulletin outlines immediate compliance requirements for applicant companies and sets a deadline of March 31, 2011, for existing approved companies to transition to the new standard. Key changes include updated definitions, a restructured content layout, and additional legislative references, emphasizing that adherence to the new guidelines is mandatory for maintaining NSI approval. Manual review recommended for complete details.
