The Tour of the Facilities

Restrictions on Working Alone

The following has been taken from the
APS User Safety Guide:

"When activities at the APS involve substantial hazards, working alone is not permitted; that is, you must remain in visual and auditory contact with a second person who understands the work being performed and all pertinent emergency procedures. The following are examples of materials or systems that are considered to pose substantial hazards:

  • high-energy or high-pressure systems.
  • acutely toxic or corrosive gases, liquids, or solids.
  • cryogenic materials in greater than bench-scale amounts.
  • flammable liquids or chemicals in greater than bench-scale amounts.
  • x-ray generators, if you are not an authorized user of the device in question.
  • electrical systems capable of producing a paralyzing shock when proper safeguards are not in place.''
In additon, when working in the LOM shop after hours, you must notify the APS floor coordinator.

The Importance of Keeping Work Areas Neat and Orderly, and the Aisles Free of Obstructions

Please remember that you are utilizing shared space for your experiment. Many people who are not necessarily familliar with your equipment will be in the same area and may need the same facilities. Keeping a minimal, organized workspace is essential to providing all our users with the facilities they need to perform their experiments in an accurate and timely manner.

It is essential that aisles, walkways, and all officially demarcated access corridors and duck-unders (lined with yellow tape) are kept free of equipment as these are escape routes in the event of an emergency.

Storage of Chemicals and Gas Cylinders

Chemicals: Please store your chemicals in the designated cabinets in the chemistry lab. Users are strongly discouraged from bringing in bulk chemicals. If you must bring in bulk chemicals, you must contact the BioCAT Safety Coordinator in order to clear the required paperwork prior to its arrival on-site.

Gas Cylinders: Charged gas cylinders should be available for your use inside hutch-D. Should you need another gas cylinder, they are stored in two places:

  • Around the outside of hutch ``D'' (either in the cage or on the wall closest to the storage ring).
  • In the cage labeled "Sector 18" in the yard on the other side of the sector 20 truck lock (just down stream of 435E).
Please use the gas cylinder dolly---located in the cage---for transporting gas cylinders; and please return it when done.
  • Please observe the following safety precautions when using gas cylinders:
    • Gas cylinders should be transported with their caps screwed on.
    • No gas cylinder should ever be left unattended when not properly secured to a designated gas cylinder rack

Proper Usage of Thermo-Luminescent Dosimeters

Do not leave the APS complex with your thermo-luminescent dosimeter (TLD).
Between the two bathrooms are TLD storage boxes. Please locate an empty box, label it with your name, and place your TLD there whenever you leave the building.

These dosimeters are only valid until the end of the calendar month.
When you leave the APS for an extended period, please return your TLD to the person who gave it to you (if from Clareen, then return it to Clareen; if from the Floor Coordinator, then return it to the Floor Coordinator). Only place your TLD in the Dosimeter Return bins if you received your TLD from the APS user office.

Proper Usage of Radioactive Check Sources

The BioCAT Safety Plan does not currently address the use of radioactive sources. Anyone who wishes to perform research at BioCAT utilizing radionucleides must have prior approval from the BioCAT staff and must adhere to all requirements specified by BioCAT, the Advanced Photon Source, and Argonne National Laboratories for their transport and use.

Storage of Other Items

Sharps: Small, sharp objects can pose a significant hazard to you, other users, and maintenance staff. Such objects include, but are not limited to: syringe needles, knife/razor blades, tiny diameter stiff wire, and broken glass. All sharp objects must be stored in a way that minimizes the risk of laceration and possible introduction of foriegn objects into the body. Methods may include insertion of the sharp surface into a sizable piece of cork or styrofoam.

Sharps are not to be disposed of in the regular trash bin!
Used syringe needles, razor blades, and scalpels must be disposed of in the sharps disposal box. Broken glass must be cleaned up immediately with the hand-broom and dustpan and disposed of in the cardboard box labeled "Broken Glass."

No item may be stored on top of a cabinet exceeding five feet in height.

Restrictions on and Proper Use of Electrical Power Strips and Extension Cords

The following has been taken from the APS User Safety Guide:

``Do not use single-to-multiple outlet converters ("cube taps"). If necessary, use power distribution strips with integral power cords and built-in overcurrent protection. These strips are available through the Argonne Materials Ordering System (AMOS).

Suspend electrical cords over the work area if possible, to avoid damaging them or creating a tripping hazard. If this is not feasible, mark the location as a work area by using appropriate signs or barricades and place "cord ducts" or other protective runways over the cords.

Properly identify electrical cables at their ends and at all spliced junctions, to facilitate eventual cable removal.... Immediately remove all cables that are no longer in use and update the tables and diagrams accordingly.

Use only CAT-issued or CAT-approved extension cords. To prevent overheating or possible electrical shock, choose cords rated for current levels that exceed your needs by a safe margin.

Never run extension cords through walls, windows, or doorways or behind walls, ceilings, or floors. Never connect extension cords in series or splice them together.

Procedure for Obtaining and Using Liquid Nitrogen

Liquid nitrogen may be obtained at the fill station in the sector 20 truck lock (just down stream of 435E) or from our house liquid nitrogen line on the upstream wall of hutch-C. Users will be responsible for refilling their own dewars once they have been certified by BioCAT staff. Proper Personal Protective equipment (PPE) is to be used while handling liquid nitrogen (gloves, face-shield, and apron).

Disposal of Waste, Including Hazardous Waste

It is recommended that white paper, glass containers, and aluminium cans be disposed of in the appropriately labeled blue canisters in the LOM, the beamline, and the communal kitchen in pentagon 'C.' Ordinary trash may be disposed of in any available trash can.

BioCAT assumes that all chemical waste is hazardous. Any procedures which generate such waste must be reviewed by the Chemical Safety Officer if this waste is to be disposed of here at the APS.

Beam-line Safety Information

"Proper attire for work in the experiment hall includes closed-toes, covered-heel shoes and long pants. Sandals or any type of open-toe shoes are not acceptable. Skirts may be worn if a lab coat is also worn." (APS User Guide section 2.1)

Orientation to BioCAT's Implementation of the APS Shielding Configuration Policy

Exposure to radiation is an important safety issue at the APS. Shielding has been placed at a number of points around our beam-line to reduce this risk such that exposure to radiation levels above natural background is virtually impossible. To maintain this level of safety, it is important that you not alter any part of the beam-line shielding. Typically, all critical shielding has been tagged, but, when in doubt, ask!

If you need to open any of the labyrinths, ask for help from your scientific contact.

Locations of the Utility Shut-Offs for Electricity, Water, and Compressed Gases

Electricity: There are two types of power: "clean" and "dirty." The outlets for clean power are orange and should only be used for electrical components sensitive to voltage spikes. No motors or other inductive components are to be connected to clean power.

Each outlet is labeled with the breaker that supplies it. These first-level breakers are located in the hutch for outlets in the hutch and on the outside of the hutch for outlets located outside of the hutch. These breaker boxes are labeled with the second-level breaker box and circuits that source power to it.

The second-level breaker boxes are located on column 119.

Water: The shut-off for water for hutch-D is located inside hutch ``D'' on the inboard wall. They are the third and fourth red handles.

Compressed Air: The shut-off for compressed air for hutch-D is located inside hutch-D on the inboard wall. It is the green handle to the right of the water shut-off valves.

Explanation of the Use of Radiation Survey Meters

The BioCAT Safety Plan does not currently address the use of radiation survey meters by users. If you need a survey meter, BioCAT staff will arrange to borrow one from the APS Health Physics department.

Users who have concerns about ambient radiation levels are encouraged to approach any of the BioCAT safety officers or an APS Floor Coordinator who will perform a survey.

General and Beam-line-Specific Operation of the Personnel Safety System (PSS)

Users will recieve training in the use of the 18-ID PSS. This training will include specific inforomation on
  • Searching a hutch
  • Closing the door
  • Enabling the shutters
  • Disabling the shutters
  • Opening the door
  • Emergency Beam Stops
  • Emergency Door Release
Only one person should work the PSS at a time. Under no circumstances is a person allowed to work in a closed hutch.
