APS Guideline for CAT/XSD Sector Orientation


The orientation described in this guideline is designed to provide the basic information needed by new users to make safe and effective use of CAT/XSD’s facilities at the APS. The CAT/XSD will also give appropriate parts of this orientation to visitors who are not expected to do hands-on work in CAT/XSD's facilities.

Contents of the Orientation

Part 1: APS Requirements

CAT/XSD will ensure that prospective visitors are aware that they must:

  • Register with the APS User Office and receive an appropriate safety orientation upon arrival and
  • Never enter a controlled area unescorted.

CAT/XSD will inform prospective users that they must:

  • Contact the APS User Office prior to arrival for guidance on registration;
  • Complete the APS User Orientation and radiation safety training required by ANL and the APS before a permanent film badge is issued;
  • Describe probable activities at the APS, complete any additional safety training that CAT/XSD or the APS specifies for those activities, and comply with hazard control measures specified by the CAT/XSD;
  • Complete sector-specific training as outlined below (CAT/XSD will provide this training); and
  • Identify on the Experiment Safety Review Form all chemicals, gases, and samples to be used in experiments at the APS.

Part 2: CAT/XSD Safety Policies and Resources

The CAT member covering the safety policies and resources portion of the sector orientation shall:

  • Give the user an orientation to the Environmental, Safety, & Health Plan of the CAT/XSD;
  • Call attention to the section entitled "General Policies" and point out that, as stated there, this manual is intended to supplement the analogous documents of ANL, APS, and the CAT/XSD member institutions;
  • Emphasize that the safety first principle is the primary tenet for performing any job, task, or experiment at CAT/XSD’s facilities, and that the success of the CAT/XSD safety and environmental protection effort depends on the commitment of all CAT/XSD personnel;
  • Introduce the user to the CAT/XSD Safety Coordinator, the Beamline Safety Technician and the CAT/XSD Manager; and emphasize the importance of bringing all safety and environmental problems and concerns to their attention.

Part 3: General Safety Information

The CAT/XSD member covering this portion of the sector orientation shall review the following topics:

  • Locations of safety equipment (fire extinguisher, shower, eyewash station, stocks of personal protective equipment, etc.);
  • Location of safety documentation;
  • Location of emergency phone numbers;
  • Responding to alarms and other warnings;
  • Use of safety glasses and other personal protective equipment;
  • Restrictions on working alone;
  • The importance of keeping work areas neat and orderly, and the aisles free of obstructions;
  • Proper storage of chemicals and gas cylinders;
  • Proper storage of other items (e.g., objects may not be stored on top of cabinets); and
  • Securing electrical power strips.

Part 4: CAT/XSD Beamline Safety Practices

The CAT/XSD member covering this portion of the sector orientation shall:

  • Explain the APS Shielding Configuration Policy;
  • Point out the locations of the utility shutoffs for water and compressed gases;
  • Discuss the use of radiation survey meters; and
    1. Explain the general and beamline-specific operation of the PSS, including:
    2. The APS policy that no one is allowed in the First Optics Enclosures (FOEs) or the Experimental Stations (ESs) when the beam is on or when the interlocks are enabled,
    3. Use of the Beamline Safety Checkout List,
    4. The inspection and interlock procedures used at the beamline,
    5. The safety interlock system and fail-safes,
    6. The locations of the Emergency Beam Dump switches in the FOEs and ESs, and
    7. The locations of the electrical circuit breakers and main breakers for the beamline.

CAT/XSD trainers will also provide the user with additional formal and on-the-job training that is specific to the Beamlines' instruments, and facilities that the user will be using.


CAT/XSD will document each person’s attendance at the sector orientation by recording the name of the attendee, the date(s) of the training via the Credit for Sector Orientation and Glovebox Training link. Training records will be kept in the Argonne TMS system.
