No.of Electricians for Animal House

02/12/2009 11:41 PM

We have constructed the new Animal House with facility of 180TR capacity of chiller units, 20kVA UPS, Fire Alarm System and other connected power loads are 80kW.All are distributed from five differant panel boards & 10 distribution boards.The Animals are to be occupied as per GLP norms.As per international standared how many qualified electricians are to be deputed for this Animal House building including operational of DG Set and change over.The power cut duration is 14 hours per day.If any other details are required, that will be given for this specfic question.I need the proof if possible indicating the website id.

You just posted this same question the other day. Please be patient while waiting for answer, and avoid such duplicate posts.

The question given in this section is to make study in this field since this is related with elctrical & Bio technology.Not for urgency.

One reason that this may not have been promptly answered is it is quite opaque.

does animal house mean like a modern zoo-dwelling place for animals? Or does it mean fraternity house like the movie and the one I belonged to when I was but a lad?

does 'the power cut duration 14 hours per day' really mean no power for 14 hours per day, and if so is it regularly scheduled or haphazard?

does 'as per international standared' mean, is their an international standard for electrician duty hours at zoo's based on deployed equipment?

does the use of past tense in "we have constructed... with the facility of ...80kW" mean that it is built, and now you are trying to determine how many electricians are required to be on hand just to babysit this thing? or is the real question how many electricians needed to build this, ignoring the past tense of the initial statement?

The idea that there exist international labor standards for this sort of thing is eyeopening, as it totally ignores the fundamentals of economics, local requirements, the speciifics of the requirements of your installed plant, and the talent available in your market. Not to mention business plan; unionization and response time on local contractors who might be brought in when the work (and its urgency) exceeds capacity of the talent on shift.

These might give some insight as to why the responses have been a wee bit on the slow side.

And while we as engineers understand acronyms such as kW, kVA UPS, The use of TR when we expected just Tons, 'DG' (diesel generator perhaps?)and "GLP" requires a google by the responder to figure out that your animal house is for laboratory raisng of animals. GLP = Good laboratory practice??? is Out of context despite being biomed section because the question is essentially an electrical engineering one. Please don't presume that people in other countries understand ACRONYMS and abbreviations. So don't make us have to do research to have to even understand your question.

In my industrial experience, I would have one electrician/ mtce person on each shift, with supervisor contact info and ability to call local contractors in emergency. But i know my equipment reliability and electricians capability and the scope of likely problems. Do you???

Good. I welcome all your comments. The buiding construction works are completed and necessary equipments are readily available in this laboratory area.The animals like rat,mice Gunia pig is to be occupied. Eventhough this decision is based on my working condtion, I request the reader to project any specfic norms for number of electricians and to share their experiance.I am not an english literature.Thank you for all

Hi,

Having been responsible for managing an estate which contains a large life sciences facility with several animal houses, including a transgenic unit I can understand your concerns for both the welfare of the stock and compliance with any relevant licencing conditions. I will not attempt to comment on the support needed to overcome the vagaries of the electrical supply that you report.

I would state from experience that provided the installed HVAC equipment is of a good quality that the most significant demands placed upon technical support staff will be to do with controls related matters. In our case we have a controls technician available 24/7 available at 30minutes notice. The individual is selected from a rota system of 3 men and is paged by an alarm generated from the Building Energy Management system (BEMS). Also available is an Electrician, a Plumber and a Mechanical fitter contactable by a similar process.

The total in-house labour pool is 14 men and they are employed on a full time basis to cover 140,000 m2 of campus property of which 25,000m2 is LS research; specialist external contractors are also available if needed but only during working hours.

Now to the tricky bit. Power failures of which we have few are guaranteed to produce a variety of problems , some at the point of activating the generators others at the resumption of mains service. If you are experiencing the sort of frequency of outages that you seem to indicate then the resultant demands upon the maintenance staff will be greatly increased. My chief concern would be that your change-over equipment will be hammered to death in fairly short order and the call-out rate will literally go through the roof.

You will have to think about having both back-up motors (if you don't already have them) with separate contactors or variable Speed Drives dedicated to all the sensitive areas. Think also about UPS facilities if in no other area than the environmental controller panels as they will not tolerate frequent power losses without possibly corrupting the programmes.

Your early days experience will be a steep learning curve.
