Safety in the Science Directorate

Work Planning and Control

WPC It is the responsibility of every individual working in the Photon Sciences Directorate (PSD) to be aware of and familiar with the hazards associated with their work and the laboratory environments that they conduct research  in. Equally everybody is responsible for following work procedures and protocols and ensuring that resources are available to perform their work in a safe manner.

SLAC’s work planning and control (WPC) program is an integral part of ensuring that safety is built in to all of our activities. The expectation from the Associate Laboratory Director for Photon Science and Line Management is that all staff, visitors or users MUST adopt and use work planning and control principles when planning and performing experiments.  Refer to the SLAC WPC Program for more details.

A DRAFT of the WPC document for Photon Science has been created.

Who do I contact for safety questions?

The Safety Coordinator directly supports PSD staff and projects and is the primary resource for assistance with all Environment Safety & Health (ESH) matters. The Safety Coordinator acts as the primary interface between you as the PSD customer and institutional ESH programs.  Photon Science also has a laser mentor who is available to provide assistance on laser related questions.  They are not here to do work for you but instead to provide guidance as needed.  Feel free to call on them if you need assistance.
