About STS


Safety Trained Supervisor (STS) Certification

The Board of Certified Safety Professionals (BCSP) awards the STS certification to individuals who are currently in (or who are preparing for) a line supervisory role and who demonstrate competency with safety-related aspects of supervision.

The STS certification began in 1995 for candidates in the construction industry. Today, a person can earn the STS certification by demonstrating competency on the STS General Industry examination, the STS Construction examination, or the STS Petro-Chemical examination. BCSP through its Board administers the STS program.

The STS certification program is intended for individuals who:

  1. 1.Are managers at all levels

  2. 2.Are first-line supervisors of work groups or organizational units

  3. 3.Have a safety responsibility for a work group that is part of other duties

Safety Trained Supervisors are not safety specialists or safety practitioners. Typical candidates have a safety responsibility that is adjunct, collateral or ancillary to their job duties. Their main job duties are in a craft or trade, in leadership, supervision or management, or in a technical specialty.

The typical STS helps an employer implement safety programs at the worker level through supervisory, safety committee or similar safety and health leadership roles. Safety tasks often include monitoring for job hazards, helping ensure regulatory compliance, training employees in safe practices, performing safety recordkeeping tasks, coordinating correction for safety problems within or among work groups, and communicating with safety specialists or management.

The STS safety responsibility is a part-time responsibility, usually less than 1/3 of the total job duties. If safety responsibilities involve a greater portion of job duties, the role is more likely to be that of a safety technician/technologist or safety professional.

The STS certification establishes a minimum competency in general safety practices. To achieve certification, candidates must meet minimum safety training and work experience and demonstrate knowledge of safety fundamentals and standards by examination. Those holding the STS certification must renew it annually and meet recertification every five years.

The Safety Trained Supervisor certification program is accredited by the National Commission for Certifying Agencies (NCCA), Washington, DC.
