PAT Testing?????

[Andrew_C]

Law states if it has a plug It must be tested

Where does it say that in an act of parliament? Don't bother looking, it doesn't. You need to risk assess and meet the requirements of various acts, but nowhere does it tell you HOW to do that.

[TechMonkey]

Law states if it has a plug It must be tested as even though you might never move it if there is a problem pat testing will pick it up. IE fuse blown so someone put bigger fuse in. This would fail pat test pat items are any item with a plug i have even had to do wall heater in the past. This is part of HASAWA. Its a nightmare but if that projector catches fire and school burns down and fire-brigade put it down to electrical fault on projector and the insurance ask to see pat log (must be kept for 5 years) and it never been done insurance will not pay out only example . Unless it has its own curcit and is wired into the mains then it must be tested. This does include projectors, whiteboards and the data colectors the plug into the mains.

 

Ohhh goody get to use my new website that someone sent me, knew it would come in handy

 

HSE Myths

[chrbb]

What about servers and ups do they need testing?

[petectid]

Going by popular definition a desktop PC or monitor aren't portable appliances either. Same goes for printers and most devices in a school.

 

If that's the case what is there left to test ?

Anything which people need to touch/move, which does include PCs and printers.

 

Projectors are portable appliances, Nick how do you change the lamp, clean the filters without touching the appliance. PAT testing is not just about protecting pupils in schools but the entire workforce that includes yourself and your colleagues. The contractors we have go a bit over the top though as I'm finding test labels on data cabs as well as the switches they house.

[TechSupp]

Not according to our LEA they are not. They have to be tested every year for 5 years and only then can you apply for them to be listed as static after having proven that they are stable so they need only be tested every few years. Portable..Yeah.

[alonebfg]

with refrance to the law bit I was trying to make it simple the heath and safety at work act Is where you will find a refrance to it and if it can be moved it must be tested and yes it includes every thing if you do it in rental home you also have to test washing machines fridges freezers etc etc. It covers everything that is connected to a ring main and does not have it own fused circuit basically everything with a plug on This includes ups servers switches etc etc

 

tanken from book

 

What is Portable Appliance Testing?

 

The 'Inspection and Testing of In-Service Electrical equipment' (usually referred to as Portable appliance testing or PAT), was introduced to enable companies & organisations comply with the Electricity at Work Regulations. To meet these regulations it is necessary to have in place a program of inspection and electrical safety testing of portable appliances. Other legislation of specific relevance to electrical maintenance - The Health & Safety at Work Act 1974, the Management of Health & Safety at Work Regulations 1999, the Workplace (Health, Safety and Welfare) Regulations 1992, and the Provision and Use of Work Equipment Regulations 1998.

 

What electrical equipment needs to be tested?

 

The regulations cover all items of in-service electrical equipment, this includes all movable items connected to the mains supply by 13A BS1363 plugs, BS EN60309-2 industrial plugs or hard wired via a fused connection unit. In addition to being responsible for the safety of their own portable appliances, companies are are also responsible for the safety of electrical equipment brought on site by employees and contractors.

 

so it includes some stuff without plugs.

 

But also it is a very gray area as IET says one thing and the HSA says another (Made a phone call today with reference to this just to make sure and was told there is no law as such people just like to cover themselves if it goes wrong and was not tested and a union classes it as pat the pat tester of that is then at fault ?? take it as you will Me i test every plug.

you are right offices are not every year but schools are ?? this is the same as in my pat book code of pratice

Just sight test the lot:

Projectors are portable appliances, Nick how do you change the lamp, clean the filters without touching the appliance.

Well, if its still on the mains, I don't. First step whenever I'm doing anything to the projectors is to hit the power kill switch on the wall - if you want to change lamps or filters on projectors which have a live power feed, be my guest....

 

That said, I perform the following steps with regards to PAT testing our projectors - nothing for the first 5 years (which at present covers all our projectors) and then a visual inspection thereafter. The only one where this could get a bit fiddly is the one which is poking through a false ceiling, as I'll have to lift the tiles up to see the cable, the rest can be done from the doorway.

[Andrew_C]

One could do a risk assessment that ends up saying something like:-

 

1) Equipment tested prior to being taken into service.

2) Equipment is "Out of Reach"

3) Equipment is not disturbed.

 

Low risk of developing fault

 

4) Equipment is DIFFICULT to reach

5) Working off ladders is a non-preferred means of access, but nothing else is appropriate for a classroom.

6) Significant risk of damaging equipment removing it from the ceiling.

 

Moderate risk of injury/damage while testing.

 

Therefore we will only test on acquisition, and at any time the equipment is taken down for re-lamping or other essential maintenance.

 

Of course, YMMV in your particular scenario.

[srochford]

Just sight test the lot:

"Er, yeh Dave that looks OK to me"

 

While that sounds a bit vague, it's actually far more useful than the full PAT stuff.

 

Let's suppose you very carefully spend the whole summer testing every bit of kit. It's all absolutely fine, you label it, log it all in your database etc.

 

September comes, people arrive in school and some little darling damages a mains cable so that bare copper is exposed. Unless someone visually checks the lead before it's used EACH TIME then you run the risk of injury or death.

 

I think this is partly why PAT is not a legal requirement. It will pick up some faults but won't pick up things which are potentially far more hazardous (if the earth connection to the metal bits of a monitor is faulty then it will fail PAT; that's not actually hazardous until something comes loose inside the machine and touches the metal. If you have bare wires because someone has tugged the mains lead part way out of something then that is immediately dangerous)

 

The Health and Safety at Work Act imposes a duty of care on every person at work - that means that everyone using something which is potentially hazardous should make a 5 second check of it before using it to make sure that there are no obvious hazards.

[chrbb]

Sorry to drag this subject up again - just spoken to our pat tester who is making his third visit to our school to finish off the annual testing.

 

He wants to test the server, that's ok because I'm in all day tomorrow and can shut the server down at lunchtime, but when I queried if it needed testing it's only a couple of months old he said that we should pat test everything before it goes into general use, regardless of the fact it's brand new. Does anyone else do this?

[enjay]

Garbage!

 

We don't test new equipment where there is a clear date of purchase (e.g. PCs) however it is done for vacuum cleaners, kettles and the like where it is much harder to identify which ones are 3+ years old and which ones are not. If you PAT test it as it comes out the box and write that date on the sticker, you know for definite when it is due its first real test.

 

Personally I would strongly resist anyone PAT testing our server - I've seen too many PCs blown with a bad test that there is no way I would trust one onto the server. Put it in the same category as the ceiling-mounted projectors discussed earlier; no one touches them and the power cable is not plugged in and out repeatedly, so a quick visual inspection will suffice.

[Andrew_C]

Garbage!

Sorry Nick, but how do you PROVE that the new equipment is safe? This is the acid test.

 

If someone dies because the IEC lead on a new PC is faulty, and you cannot PROVE in court that you had done the "reasonably practical" inspection and testing, your ass is in the sling.

 

I was taught that this initial test is necessary as 1) production testing is only done on representative samples, and 2) to give you a baseline to determine whether an item is deteriorating over time.

[enjay]

It's actually the school's ass in the sling, not my personal one, but in that instance I would have noticed the split wires and not used the cable. Let's face it, it is very difficult to unbox and assemble a new PC without carrying out a visual inspection on it! Legally, that inspection will suffice for the next five years (morally is another question, of course!).

 

Let's assume for a moment that I do test every cable and PC as they come out the box, just like you are. What guarantee is there a month, week, day or even hour later that the PC is still safe? Absolutely none. So let's imagine that we both buy new PCs in January, I will visually inspect the cables while you fully PAT test yours, and then randomly both our PCs electrocute someone in October that year - is your ass any less in the sling than mine?

[alonebfg]

Actually its your ass if you are the pat tester yes the school will get into trouble but such has been pointed out in this thread before it is everyone's responsibility and if you are head of it equipment that's your ass in the firing line. and people should test every day as part of pat a visual inspection can tell a lot. and electrics do not fail like that to short or electrocute someone there needs to have been someone doing some serious damage and the fuse (pat test includes checking fuse rating) rating is the correct. this would cause a overcurrent and the fuse would blow before electrocutes you.

[Andrew_C]

Sorry if I've mis-interpreted, but it is a bit difficult to make out your meaning.

 

Not all faults will cause a fuse to blow without killing you first, and many can go undetected. For example, an earth core can degrade leaving just one strand intact. Visually, nothing to show, a simple test will show continuity, but under fault conditions it wouldn't carry sufficient current to provide safety. A proper test at 2x rated current will rupture it and show up the problem.

 

High earth loop resistances will be detected by a proper test, and if you are keeping good records, a slow degradation can be detected before anyone gets hurt.

Huh? proving in court would simply be 'we bought an object which connects to 240v power and is legally required to be fit for purpose and not faulty. It was faulty therefore the responsibility falls into the manufacturer's lap - not mine.'

[Andrew_C]

That does NOT prove that you took 'all reasonable care'. It proves that you trusted the manufacturer, nothing more.

[Joedetic]

As an aside I seem to remember once being told that equipment that is mounted in a rack (ie, static kit...not portable like switches and servers etc) doesn't need to be tested.

 

What's the stance on this? Does it actually need to be tested?

Our PAT testers leave it to the discretion of the school when it comes to switches and servers.

 

I have always told them not to bother, but legally im not 100% where I stand on this one.

[localzuk]

Which is reasonable care, as it is reasonable to expect new equipment to work as supplied.

[enjay]

For example, an earth core can degrade leaving just one strand intact. Visually, nothing to show, a simple test will show continuity

Which is why we test older equipment which has had time to degrade in the way you describe. A straight-out-the-box cable will be fine (the manufacturer is legally required to test them) so we can put it into immediate use, and then add that cable to the testing schedule.

[chrbb]

Right all our pat testing done - not by me I might add.

Tester replaced fuses in most things including 4 month old monitor leads because the cable in the leads wasn't the right sort for 13 amp fuses, these were the leads that were supplied with the monitors.

I'm now quite confused about this!

 

He was very thorough (and humourless) - it's been a long day!

[Oops_my_bad]

Old place where I worked, stuff like servers and switches were just visually inspected, not as if you can stop a production line just so you can PAT test the servers/switches!

You're lucky your tester has the nonce to actually ask about testing servers. The twit doing ours just unplugged the bloody things over the half term holiday when nodody was about... *GRRRRRRR*
