ESH Mission and Policy


The Environment, Safety, and Health (ESH) Division supports the SLAC National Accelerator Laboratory's mission and vision by sustaining excellence and enhancing the effectiveness of integrated safety, health, environmental protection, and security.


SLAC Environment, Safety and Health Policy

Policy Statement

SLAC is committed to protecting the health and safety of on-site personnel, the public, and the environment as it carries out its scientific mission. Each of the laboratory’s directorates is responsible for implementing the Environment, Safety and Health (ES&H) Program through line management. In addition, management at all levels is expected to ensure that all employees understand the content and importance of this ES&H Policy.  In turn, employees are responsible for integrating ES&H considerations into their own work activities.  The SLAC Director has ultimate responsibility for ES&H at the laboratory.  

Through employee and management involvement SLAC will:  

  • Use our Integrated Safety and Environmental Management System to protect human health and the environment through  
    • Defining the scope of work  
    • Identifying and analyzing the hazards
    • Developing and implementing hazard controls  
    •  Performing work safely
    • Soliciting and using feedback for continuous improvement
  • Seek to maintain a healthful and safe workplace, free of recognized hazards and occupational injury and illness  
  • Wisely use and conserve natural resources and conduct our activities in a sustainable manner  
  • Conduct operations such that the production of radioactive materials and exposure to radiation is maintained as low as reasonably achievable  
  • Integrate environment, pollution prevention, safety, health and quality into project planning, design, construction, operations, maintenance, and decommissioning of facilities  
  • Ensure compliance with all applicable laws, regulations, and best management practices
  • Put policies, programs and professional ES&H staff in place to ensure line management can carry out their responsibility for ESH implementation  

Workers have the authority and responsibility to stop, or not perform, any task when there is a reasonable belief that the task poses imminent risk of death or serious injury. In such a case, the workers must report this to their supervisor immediately.  

SLAC recognizes the need to learn from successes and deviations from expected outcomes, and encourages workers to both report these instances and provide feedback. This is an essential part of our continuous improvement.
