Silica Exposure Control Plan

Roles and Responsibilities

The Silica Exposure Control Plan (SECP) is administered by Environmental Health and Safety. Departments who perform construction, renovation, maintenance or repair activities that affect building or other materials potentially containing silica, and from which respirable dust could be generated, shall designate a Safety Representative to coordinate the requirements of this program in the department. All other departments that have work operations that use or create respirable crystalline silica (RCS) shall comply with the requirements outlined in this program.


Departments performing construction, renovation, maintenance or repair work covered by this section shall:

  • Designate a safety representative to coordinate monitoring, evaluations and training with EHS, and to provide oversight on departmental operations to determine when work activities may generate RCS that will require review by EHS.
  • Ensure the work practicies and procedures used to control exposure to RCS comply with this program.
  • Ensure all reasonable precautions are taken to prevent exposure of bystanders and the general public when work involving RCS is performed.
  • Ensure covered employees attend required training, and participate in the Occupational Health Assurance Program if required.

Designated Safety Representative (DSR)

Designated departmental safety representatives are responsible for the following:

  • Notifying EHS when work activities are planned that may generate RCS where monitoring may be required.
  • Working with supervisors to review all power tool usage to assure compliance with the dust controls established in the SECP. Where respirators are required by the SECP, assure supervisors only allow employees who have been approved to use respirators to perform those tasks.
  • Assuring regulated areas are established, dust controls are used to prevent migration of dust from the worksite, and air supply and returns in the work area are covered when work will be performed near areas occupied by the general public and respiratory protection is mandated in the SECP.


Supervisors shall assure that:

  • All employees who perform work that may geneate RCS have attended Silica Awareness Training.
  • Work tasks that may generate RCS comply with the SECP.
  • Employees participate in the EHS Occupational Health Assurance Program if the task requires use of respiratory protection.
  • EHS is provided advance notice if work will be performed that is not outlined in the SECP and where no prior exposure monitoring has been performed.


Employees shall perform all work in accordance with the SECP.

Additional training or services may include, but is not limited to:


Environmental Health and Safety will provide technical support, employee exposure monitoring, and oversight for this program; however, involvement by EHS does not relieve the departments, supervisors, or contractors of their individual responsibilities. EHS responsibilities for this program include:

  • Developing, implementing, and administering the Silica Exposure Control Plan, including delineation of responsibilities and standardized work procedures (SWP).
  • Providing awareness level for all employees performing work that may generate RCS, and maintaining centralized training records.
  • Providing respiratory protection training and fit-testing for employees.
  • Serving as a technical resource for program application on campus.
  • Performing employee exposure monitoring, documenting the level of exposure to RCS for various tasks, and updating the SECP to include these new tasks along with required PPE.


Contractors shall comply with the Safety Requirements for Contractors and Subcontractors Program.
