Emergency Electrical Power


I. PURPOSE:

The purpose of this policy is to prevent the emergency power systems from becoming overloaded during a power failure from the public utility electrical service.

II. SCOPE:

This policy applies to all physicians, staff, patients, volunteers, and visitors in Clarian Health facilities

III. DEFINITIONS:

A. Branch Circuit. The circuit conductors between the final overcurrent device (circuit breakers) protecting the circuit and the outlet(s).

B. Critical Branch: A subsystem of the emergency system consisting of feeders and branch circuits supplying energy to task illumination, special power circuits, and selected receptacles serving areas and functions related to patient care, and which are connected to alternate power sources by one or more transfer switches during interruption of the normal power source.

C. Electrical Life-Support Equipment: Electrically powered equipment whose continuous operation is necessary to maintain a patient?s life.

D. Emergency Power receptacles: Electrical receptacles that are either painted red, orange or blue or labeled as such.

E. Emergency System: A system of feeders and branch circuits meeting the requirements of Article 700 (Emergency System), except as amended by Article 517 (Health Care Facilities), and intended to supply alternate power to a limited number of prescribed functions vital to the protection of life and patient safety, with automatic restoration of electrical power within 10 seconds of power interruption.

F. Equipment. A general term including material, fittings, devices, appliances, luminaries (fixtures), apparatus, and the like used as a part of, or in connection with, an electrical installation.

G. Feeder. All circuit conductors between the service equipment, the source of a separately derived system, or other power supply source and the final branch-circuit overcurrent device.

H. Generator: A diesel power motor that turns mechanical energy into electrical energy. That shell automatically starts on failure of the normal service and for automatic transfer and operation of all required electrical circuits.

I. Life Safety Branch: A subsystem of the emergency system consisting of feeders and branch circuits, meeting the requirements of Article 700 and intended to provide adequate power needs to ensure safety to patients and personnel, and which are automatically connected to alternate power sources during interruption of the normal power source.

J. NEC: National Electrical Code

K. NFPA: National Fire Protection Association

L. Normal Power: Normal electrical power provide by the public utility electrical service

M. Overload: Operation of equipment in excess of normal, full-load rating, or of a conductor in excess of rated ampacity that, when it persists for a sufficient length of time, would cause damage or dangerous overheating. A fault, such as a short circuit or ground fault, is not an overload.

N. Power Failure: When the public utility electrical service quits producing electrical power, or a piece of main electric equipment beaks down.

O. Receptacle Identification. The cover plates for the electrical receptacles or the electrical receptacles themselves supplied from the emergency system shall have a distinctive color (red, orange or blue) or marking so as to be readily identifiable.

P. Selected Receptacles: A minimum number of electric receptacles to accommodate appliances ordinarily required for local tasks or likely to be used in patient care emergencies.

Q. Shall. Indicates a mandatory requirement. [NFPA 99: 3.2.7]

R. Task Illumination: Provision for the minimum lighting required carrying out necessary tasks in the described areas, including safe access to supplies and equipment, and access to exits.



IV. POLICY STATEMENTS:

No unauthorized equipment shell to be plugged in to the emergency power plugs, without written approve from Hospital Facilities.

i.e.
Coffee makers
TV?s, radios
Copy machines
Microwaves ovens
Refrigerator
Space heaters
Computers and printers (not used in direct patient care)
Or other non-Critical equipment


V. EXCEPTIONS:

Any exceptions or deviations from this policy shell be at the sole discretion of the Director of Facilities

I think you need to omit any references to the NEC and NFPA and put everything in layman's terms. This is much too complicated and technical for those defined in the Scope (above).

By the way, Mike Holt very rarely visits this board.

Drawings and pictures are better than words. Its pretty wordy. Your medial staff are busy and have enought to read.

I have to agree wholeheartedly.

Do you really expect those that this is aimed at to care enough to read it all and understand it?

IMO you would be better off with labels at each outlet that simply stated.

"EMERGENCY USE ONLY"
"For Further Info Call Facilities"

Or something like that.
 
Re: Emergency Electrical Power Policy

For starters, doctors are not going to accept the notion that they must obey a policy statement issued by an electrician.

But more importantly, you began with the wrong step. You need to define the problem, before you can solve the problem. So, what is the problem you are trying to solve?
</font>
  • <font size="2" face="Verdana, Helvetica, sans-serif">Do you have visitors who plug copier machines into "emergency power plugs"? If not, then why are you addressing this to visitors?</font>
<font size="2" face="Verdana, Helvetica, sans-serif"></font>
  • <font size="2" face="Verdana, Helvetica, sans-serif">Do you have patients who plug their computers and printers into "emergency power plugs"? If not, then why are you addressing this to patients?</font>
<font size="2" face="Verdana, Helvetica, sans-serif"></font>
  • <font size="2" face="Verdana, Helvetica, sans-serif">Have you experienced an actual or "close call" overload of the emergency generator, with the cause being determined to be too many things plugged into "emergency power plugs"? If not, then why are you citing overload as the purpose of this policy?</font>
<font size="2" face="Verdana, Helvetica, sans-serif"> Who is doing what that you don't like, and what have you done about it in the past? For example, if you see a radio plugged into an "emergency power plug," do you have the authority to unplug it on the spot, or do you have to issue some formal complaint to the Director of Facilities?

That is without a doubt one of the most accurate statements I have seen in a long time.

I laughed out loud when I read it, the same can be applied to scientists.

Electricians are mere mortals....

Re: Emergency Electrical Power Policy

A load shedding transfer switch, or a more limited number of branch circuits and receptacles in non-patient care areas would probably be more effective.
