Change Analysis - Management of Change (MOC)

As you know, change is continuous on a construction worksite. Change analysis, also called management of change (MOC) is a best practice used to ensure that safety, health and environmental risks are controlled when a company makes changes to the worksite, documentation, personnel, or operations. It should be conducted by competent persons, to make sure it does not introduce new hazards or unsafe procedures in the work environment.

A designated person should analyze how changes on the worksite can affect equipment, processes, and materials for hazards and potential hazards. Findings should be documented and plans developed to minimize or design out the new hazards.

Changes in the following categories need to be reviewed:

  1. worksite layout
  2. contractor/subcontractors
  3. tools, equipment, and materials
  4. process design and technology

The following items should be included in the management of change procedures:

  • the technical basis for the change;
  • impact of the change on safety, health, and local environments;
  • necessary time period to implement the change;
  • management approval procedures for the change;
  • changes should be documented and dated; and
  • employees and contractors should be trained if their job tasks will be affected by a change. They should be trained prior to startup of the process or affected part of the operation
