Power Outage Procedures

What to do in the event of a power outage.

Exactly how you deal with a power outage will depend on how long the power is out and what problems you find.  This section provides procedures to use in the fairly simple case when the power is not out long enough to outlast the UPS units on the servers, and it provides a little info on what to do with a longer power outage.

The majority of the computers in Sitterson run on a switched power grid, using the orange wall sockets.  The rest, mostly servers in SN122, have some amount of backup power.  The department’s switched power grid is automatically switched off when there is a significant power fluctuation.  This prevents damage that would otherwise be likely to occur if the power were allowed to flicker on and off, as in a brown-out.  To get the power back to the systems on conditioned power, you must switch it back on in the main utility room, SN042. Instructions for doing this are given below, after the steps which must precede turning on the power.

Before you switch the clean power back on, you must first verify that 1) power to Sitterson is back on and stable and 2) the server systems in SN122 are up.  To verify that the power is on, just check any office light.  If it will come on, you have power.  To verify that it is stable, call Physical Plant at 962-8394 and ask.  After hours, you will be switched to University Police.  Ask them if it is stable or to check with Physical Plant.

To verify that the important systems are up, go into SN122. In particular, check to see if bristol and charlotte are up. Then check the PC servers in the big blue computer cabinet and make sure they are up.  If all these systems are running, then the power outage was not long enough to take the servers down, in which case one person should be able to handle things.  If these systems have shut down, then you will need to call in the troops, at least one PC admin and one UNIX admin, for assistance.  You should not proceed to turn on the clean power until you get the servers up.  In this case you should also put a preliminary sign up on the exterior doors saying that the power went down long enough to outlast the UPSs and bring the servers down.

Once you have verified that power to Sitterson is on and stable and the servers are up, you can turn on the switched power.  The best way is to contact UNC Facilities, or after hours, Campus Police and ask that an electrician be dispatched to reset the grid. They should be here within 20-30 minutes. But if you need to reset it yourself, unlock the lock box in SN128 and remove the key labeled “Mech Room”, you can use that to unlock SN042. Instructions on resetting the breakers is on the north wall.

Once the switched grid is back, most computer and network switches around the building that were off will start coming back on.  At this point, you need to check and make sure things came up okay.  Check an office PC and see if it is up and able to see other systems in Network Neighborhood.  If so, then DNS and DHCP should be working fine.  Log in to a UNIX machine and verify that you can see your home directory.  If so, at least one of the AFS servers is okay.  Run /usr/local/bin/netcheck.  This will report on network devices that are down.  Don’t worry about the experimental networks (which are so indicated in the output), but if other devices report down, you should go to the indicated network closet and power cycle the device.  This normally fixes it.  Check a telephone and make sure it is working okay.  If not, call David Musick from a phone outside Sitterson.

If things don’t come up, use your judgment about what to do and whom to call.

The last thing is to let people know the status of the systems.  Post a note to change-notices@cs-old.sites.unc.edu, and post signs on the exterior doors with the same information, being sure to include the date and time that you made the sign and your name.  Depending on what is not working, it may be reasonable to go around the building and inform anyone who is there of the status of operations.

Obviously a lot of things can go wrong, but they usually do not (other than the power going off in the first place).  Use your best judgment about what to do, when or if you call in help, whom to call, how to notify.

Purchasing Supplies and Equipment

How to make purchases for equipment and supplies with University funds

The University makes a distinction between supplies, which cost less than $5000, and equipment, which is anything that costs $5000 or more.  All equipment purchases must be handled through either Computer Services or the accounting staff.  Further, all purchases of computers must be handled through Computer Services, and related hardware and software purchases should also normally be handled through Computer Services, by sending email to help@cs-old.sites.unc.edu.

You should generally handle other purchases through the department’s accounting staff.

Occasionally the accounting staff receive cash receipts for supplies (items costing under $5000) from users who want to be reimbursed for these out-of-pocket business expenditures.  We understand that there are times when you experience some difficulty in locating a special item, and subsequently pay cash when you find it.  This could result in your not being reimbursed unless the purchase was approved in advance by the Accounting Manager (Sandra Neely), as well as the Principal Investigator for the grant that you want to pay for the supplies.

NOTE:  The campus does not allow reimbursement for personal purchases of supply items.  To avoid spending your own money with no way to be reimbursed, you should handle all computing purchases through Computer Services or the accounting staff.


Spill and Breakage Procedures

How to deal with spills or sharp materials in the Shop

CONTACTS

  • Emergencies: 911
  • UNC EHS: (919) 962-5507

Many chemical spills are of limited hazard potential and can be safely cleaned up by personnel on site. In general, the Department of Environment, Health and Safety (EHS) should be called if the spill presents a respiratory hazard, or otherwise poses a threat of fire or explosion. EHS should be called if the spill is:

  • more than 100 ml of an OSHA regulated chemical carcinogen or a highly toxic chemical; or,
  • more than 1 liter of a volatile or flammable solvent
  • more than 1 liter of a corrosive (acid or base) liquid

At the time of this writing, the only chemical we have in that meets those criteria is Isopropyl Alcohol, as we have about 4 liters in the cabinet. We do have small quantities of oil, paint, and cleaners, however.

REQUESTING ASSISTANCE FOR CHEMICAL SPILLS

There may be some spills that are more hazardous and clean up should not be attempted by Computer Services personnel. This event should be very unlikely as we do not keep such materials on hand, but if you are in doubt as to what to do, please evacuate the room and contact the Department of Environment, Health and Safety immediately.

In the event of major uncontrolled incidents such as fire, major releases of hazardous chemicals to the environment, or life threatening injuries, 911 should be called immediately. If you can safely retrieve the MSDS binder, please do so and hand that over to EHS or other emergency personnel when they arrive.

RESPONSE STEPS FOR CHEMICAL SPILLS

  1. Leave and Control Spill Area
    Evacuate personnel from the immediate spill area.
    Block off immediate spill area-close corridor doors, use lab carts, wastebaskets, etc. We also have some caution tape in a cabinet in the shop.
    Eliminate any fire hazard especially if spill is flammable or combustible- turn off burners, electrical equipment, etc.
    Post sign, “Spill Area – Keep Out”
    Alert other personnel in laboratory and adjacent areas of a chemical spill including the PI or Instructor.
  2. Help Injured Personnel
    Take care of injured personnel-move from spill, remove contaminated clothing, flush skin with water. There is a first aid kit in the Shop, and one in the Catering Kitchen area of FB135.
    Call 911 to seek medical attention if chemical is splashed in eyes, and/or there are burns or respiratory problems.
  3. Evaluate Hazard
    Make preliminary evaluation of hazard and identification of risks and decide whether the Department of Environment, Health and Safety (EHS) should be called. If there is any doubt, call them.
  4. If the Spill is Small and Presents No Danger
    We have a spill kit, safety glasses and gloves in the Shop on the EHS shelf, use those to cleanup up the material.
    Place all cleaning materials and the gloves into a plastic bag from the kit.
    Seal the plastic bag, label it as to the contents, and put the bag into the plastic pail.
    Contact EHS for advice and pickup.
    Replace used materials in spill kit.
  5. Critique Incident
    Critique incident to prevent further spills and improve response procedures.

GLASS AND OTHER SHARP MATERIALS CLEANUP

In the evident of broken glass or other sharp materials such as metal shavings, nails, or blades, which do not involve chemicals, please sweep up the material and put it first in a plastic bag. Then either put the bag immediately in the trash dumpster outside the building, or into an appropriate container such as a cardboard (not corrugated!) box, seal with tape, and place in a trashcan. Do not place sharp materials loose in trash cans as that poses a danger to other staff. If in doubt, contact bil, Mike Carter, or Jim Mahaney on disposal of sharp items.
