Users are not required to wear radiation dosimeters (TLD) while on the experiment floor. However, a TLD will be issued if any of the following criteria are met:
• If you are to work in a posted Controlled Area where it is required by radiological postings.
• If you are to work with radioactive material samples, sealed sources, or x-ray generators
• If you are pregnant and request a TLD.
• If you request one.

Signal: A steady alarm-clock bell

Action: Evacuate building. Assemble in front of pentagon if the alarm is sounding in the LOM. Wait for further instructions from the person wearing the orange Area Emergency Supervisor (AES) hat.

Signal: Public Address announcement [inside] and wailing siren [outside]

Action: Move to tornado shelter. There are three shelters in the BioCAT area: The two bathrooms on either side of pentagon The machine shop

Signal: Twenty (20) second tone over Public Address system.

Action: Listen for information following tone.

All yellow safety boards contain contact information for beamline personnel.  For emergency medical assistance or to reach the fire department, dial 911 from any phone.  From a cell phone, dial 1-630-252-1911.

All phone numbers inside the laboratory can be reached by dialing a 2 followed by the last 4 digits of the phone number.  For example, 2-0560 will reach the secretary's office or 2-0101 will reach a digital pager for the floor coordinators.  When using a digital pager first dial the pager number, such as 2-0101.  When the call connects a voice will ask you to enter the telephone number you want the person to call back on.  Enter the last four digits of the phone number and wait for the call.  Usually they will call back within a few minutes.  After 10pm it could take 5-10 minutes.

All Experimental Safety Approval Forms (ESAF) should be posted on the hutch door.  These forms require at least one person from the group to give updated user contact information so they can be reached by SBC staff during their visit.  All personnel listed on this form that are present for the experiment must undergo hutch training.  Once training is complete, all trained users must sign the beamline training form; this form is posted on the yellow safety board.  Sector 19 training is only good for the period of the experiment.  When users return for their next visit they will have to repeat the training.  This only applies to Sector 19 training, not required APS training.

Other safety information may be present on the hutch door if special equipment is being used, such as an x-ray generator.  Please be aware of any special conditions in the experimental hutches.  You will be alerted by your host if any restrictions are in place during your visit.

Inside the wetlab there is a separate yellow safety board.  This board contains contact information for beamline personnel and a spot for posting the current hazard assessment forms used by the experimenters on 19ID and 19BM.  All chemicals brought in by an experiment should be listed on this form.  Any special chemicals, particularly radioactive chemicals, must be listed on these forms and reviewed by the APS and Sector 19 personnel before the experiment starts.  A full safety review must be performed for all experiments before the ESAF can be cleared.

Your host will perform wetlab training as part of Sector 19 orientation.  Once completed, the training form will be posted, with signatures, on the yellow safety board.  All personnel, regardless of whether or not they plan to use the wetlab, are required to sign the form after receiving wetlab training. 

All forms remain posted for the duration of the visit and are considered public information.  If you are performing a proprietary experiment or do no want outside users to see what you are working on, you can make arrangements with SBC staff to have your information kept in a secure location rather than posted in the wetlab or at the beamline.
