CSB adopts policy on worker participation in investigations

Policy calls for a “reasonable number” of workers and their representatives to participate

Posted November 13, 2018

The U.S. Chemical Safety and Hazard Investigation Board (CSB) has adopted a policy requiring worker participation in CSB investigations. The policy states that workers often are critical sources of information relevant to chemical incident investigations. CSB says individual employees often serve as witnesses and that employee organizations may be able to provide information vital to understanding facts and circumstances that led up to a chemical incident.

The policy calls for CSB investigators-in-charge to offer a reasonable number of workers and their representatives the opportunity to participate in investigative activities such as:

  1. Investigation opening meetings, status update meetings, and closing meetings;
  2. Site walk-throughs and on-scene investigation activities;
  3. Equipment, material, and sample evidentiary testing;
  4. Employee witness interviews;
  5. Document requests; and
  6. Review of draft written reports and recommendations.

CSB’s policy also covers whistleblower protection and interference with employee participation in investigations.
