CHM Alliance Ambassadors


Crane, Hoist and Monorail (CHM) Alliance (Signed October 05, 2005; renewed October 29, 2007; renewed November 21, 2012; renewed February 02, 2016; signed as Ambassador May 19, 2021).

Ambassador status reflects OSHA’s recognition that an Alliance participant has built and will continue to maintain a productive cooperative relationship with the agency. OSHA expects that Alliance Program Ambassadors will continue to share timely and relevant safety and health information with members and work collaboratively on issues that emerge among its membership. However, Ambassador participants do not have the data reporting and other requirements that come with a formal Alliance. Ambassador relationships remain in effect for the duration of an ongoing cooperative relationship and a good faith effort by both parties to meet the intent of the arrangement.
