(Site Profile/Docket Number 252)

Location: Beverly, Massachusetts

Also known as:  Metal Hydrides Corp.
                          Ventron Div., Morton Thiokol, Inc.

Worker Outreach Activities

Based on a recommendation from the Advisory Board to provide workers and site experts with opportunities to participate in developing the technical documents used in dose reconstruction, NIOSH established a Worker Outreach Program.

At Worker Outreach Meetings, current and former DOE and AWE employees have opportunities to obtain information about Site Profiles, Technical Basis Documents, and Technical Information Bulletins, and to provide information for consideration and possible use in dose reconstruction. This process is valuable to ensure that the technical documents used in dose reconstruction contain correct and useful information.

Below are the Worker Outreach Activities for the Ventron Corporation:

At the current time, worker outreach activities have not been scheduled.
