911 and Emergencies
In an emergency, you may dial 911 from any Argonne landline telephone, or 630-252-1911 from a personal cell phone. This will connect you with the Argonne Onsite Emergency operator.
If you need assistance out on the experimental floor, tell the operator the column number of Sector 18 - which is Column 118.
If you are in the LOM, tell the operator the Building number, which is Building 435B.
What constitutes an emergency?
For example:
- Any injury which requires medical assistance
- A security issue where people may be endangered or you fear for your safety
- A hazardous material chemical spill
Do not hesitate! If you feel that a potentially dangerous situation exists, place the call. It will be answered by the ANL Fire Department which is on-site, and will also be monitored by the Argonne Protective Force.
Fires, Tornadoes, and Other
Fire Extinguishers
You will see fire extinguishers in locations around APS. These are only to be used by firemen and those who have received the official ANL fire extinguisher training. Do not attempt to fight fires yourself. Please call 911 in a fire situation.
Emergency Alarms
The APS has a two-stage fire alarm system. If you hear a fire alarm out on the experimental floor where the beamlines are, move to the LOM (Lab-Office Module) areas. If the fire alarms are also ringing in these areas, you will be given instructions on what nature of the emergency.
If the emergency is a fire and you are being asked to leave the building - proceed to the nearest emergency exit, turn right once outside, and continue to the assembly area in the 435/APCF parking lot. If the emergency is a tornado, please go to the nearest mens’ or womens’ bathroom as these are the tornado shelters.
