Question about electric shock

[Pete999]

Tel I know what he did and what an icon he was, but really that rendition was horrendous, nothing less, sorry mate but I;ll stick with the BH version.not fade away grateful dead - YouTube - https://www.youtube.com/results?search_query=not+fade+away+grateful+dead

maybe this version is more to your liking

 

[Pete999]

This one sorry

Your body resistance when dry can be as high as 80,000 -100,000 ohms but as low as a few thousand wet, so many variable also can effect this figure like your health, skin conditions or even whether your wearing anything topical like a cream.
Once the electricity has broken down the skin which LV can do quickly then this quickly drops your resistance as low as 300-500 ohms if the entry exit points remain the same.
Like mentioned before, mostly when you receive a shock you are parallel to the supply and earth, N or other phase and thus you will be getting the full supply through your body, currents as low as 1mA can set your heart in to fibrillation if your unlucky enough to have the current pass through it and as the heart is a main junction of your blood vessels then its a risk many have lost their lives to, like most sparks Ive have many a shock over the years and the majority I can honestly say were not through my own stupidity but even though we can carry the career scars of numerous shocks I would never get complacent to its potential (no pun intended) to kill you, it only takes it to find that route of least resistance through your heart and even a mild short lived shock can be you end of days.


Its easy to assume 30mA is a safe value due to RCD's been labled for personel protection but they are this rating as its a balance between protection and nuisance tripping but even a fully functional RCD cannot stop electricity killing you as it is only there is reduce the chance of serious/fatal injury.

I must also add that 230v is a mean of the AC waveform and your body will be subject to the peak voltages which are much higher so this will further speed up the breakdown of skin resistance.

pls help...a friend of mine was opening a door of an industrial hot cupboard 13amp,whist holding another oven type door, he got an electric shock and broke his arm, the hot cupboard was earlier moved and got wet
why did this happen if the equipment is cert safe etc

Has this happened recently because that is a reportable occurance.

it hasn't happened before... but the owner of the equip said he has a certificate , so if there was a fault why didnt it come up in a check

So has your friend recently received a shock and as a result broke his arm.

it was a punishment for the arm sticking his fingers onto live parts.

Can I ask what sort of certificate was issued? is this hot cupboard portable. static and should it be subject to an ISITEE Regime?

if i could also ask you, if its a reportable occurrence,what would happen if its goes on unreported...

Someone in a responsible position would get sent to the naughty step, seriously not acting on a re portable/dangerous occurrence would involve investigation by the HSE and possible criminal proceedings could ensue depending on the findings.

It is a legal requirement of the Reporting of Injuries, Disease and Dangerous Occurances Regulations 2013 (RIDDOR) to report such an injury.

My guess is that the equipment was safe until it was moved. This may have damaged the supply cable, or pulled out a conductor so that the case became live. Only speculation, but this must be reported as it was in a place of work, and the whole properly tested before it is put back in service.
Your mate probably has a case for compensation.
EAWR!

yea

im not sure on what cert it has...but yes its portable, its one of these auto chef things that's used in functions

 

[westward10]

Well this is definitely a reportable occurrence and the HSE must be notified. At the worst a representative from the HSE will attend to assess whether there is sufficient evidence to enable a court to prosecute, most likely they will issue improvement notices but who knows.

oh rt, thanks

I know exactly the type of equipment your talking about. I bet you the flex has become damaged somehow whilst transporting, either that or an internal fault causing parts not intended to become live reaching dangerous potential.

I hope the hot cupboard has been put somewhere where it can not be used until investigation has taken place?

im going to have to check this out... thanks

I have to ask are you the person that needs to report this.

I'm sorry but did you say the electrical appliances got wet? ... Is there no safety protocol in place that should have seen it taken out of use until it was tested and shown to be safe... was the cert issued before or after the appliance got wet and if after I would get an independent check on the appliance to see if it has been issued a safe to use cert' when it was clearly dangerous, was this a PAT cert because I've seen some shocking examples of dangerous equipment returned to service because someone with no previous electrical knowledge has taken a day course and been seen as fit to make these evaluations.
