Posted By Sovay Shaw Dear H&S Colleagues
Following yet another 'shocking' experience whilst trundling my trolley round a very large supermarket yesterday, can I ask for some help in surviving the next visit? I have waded my way through the 'Search' facility on this subject.
Is there anyone out there who is actually involved in research etc. relating to supermarket trolley use? Please don't tell me how/why it happens - I've done my research - just tell me how to stop it!
When I enquired what they were doing to reduce the problem, the supermarket said "It isn't a h&s issue" and frankly, they couldn't be bothered with it. It's easy to pick out fellow sufferers by the curious dance we perform. A crack, a yelp of pain, a leap backwards with hands waving wildly in the air, (surely that in itself must constitute a risk to others?), followed by a faintly embarrassed look as we slink off to safer areas.
Any comments? (Internet shopping and let their staff get the shocks!)

Posted By Ali Turf Sovay, It might be an idea to contact their H&S Professional to ask what their response is going to be, as members of the public are experiencing this phenomenon on a regular basis, Ali

Sovay,
not sure how to stop it. Perhaps an anti static chain that trails under the trolley like you used to see on hospital beds?
I know its no comfort to you and fellow sufferers......but it is funny to see whilst trying to break the monotony of being dragged around the supermarket.

Posted By Andy Brazier Are you suggesting this is a health and safety issue? I can't see why.
Also, is it really the trolley causing the static. I'd guess it is you, with the trolley giving the earth. Wearing non-insulating footwear may help.

Posted By Margaret Baxter Static electricity is a H&S issue for cochlear implant users (there are an increasing number of deaf children, and adults, who are being implanted with these now) as it can occasionally damage the internal parts of the device as well as corrupting the programs on the speech processor. Good luck with your quest!

Posted By Jane Blunt Echoing what others have said, we do not have enough information to figure out what is happening. Please could you tell us how these 'shocking' events happen.
e.g. Is it when you touch the trolley after walking about browsing the aisles?
Is it when you touch the aisles?
Is it when you touch something at the checkout?
Or what?????
What sort of material does the floor covering seem to be made from?

Posted By Sovay Shaw Interesting comments.
I like the idea of the spectator sport (but only as a spectator). As to footwear, I'm an average woman - do I have to change into special 'safety shoes' to do my shopping and if PPE is required, shouldn't there be safety signs at the site entrance?
As to the safety aspect, my husband has a pacemaker, so I'm a tad concerned that he might be affected,(even more than seeing the bill at the checkout!) So should all trolleys be fitted with some sort of earthing device as it affects so many people? (I counted 5 more on this one short trip).
Keep it coming. Sovay

Posted By Alan Nicholls The problem you are experiencing could be down to the amount of synthetic fibres you are wearing, including the type of soles on your shoes. The trolley or the shelving acting as the earthing rod. I get the same problem with cars, they charge me up, providing I don't touch metal on the car, I can produce a 1/4 spark on the garage door. It HURTS!! Minimised effects by use of much more cotton clothing and changing type of footwear.
Not very scientific I know but it seems to work for me. Better than being zapped every time I use a car. Regards Alan N

Posted By Andy Brazier Google of 'cochlear implant static' came up with this 'Static electricity is occasionally a problem when handling a Cochlear Implant. Most implants are protected from static electricity damage but it is best to avoid a problem if you can.' from http://www.cornwall.gov....ndex.cfm?articleid=13722Seems it is only a problem when the static discharge is directly through some part of the implant, so not when gets a shock when touching a trolley. I doubt there would be any problem with a pacemaker. Being an internal device I can't see how it would see the charge. Also, it is a very well known phenomenon and pacemakers would be designed accordingly. Finally, you miss the point. If you are getting the charge, the trolley is providing the earth. Earthing the trolley as suggested may make it even worse. I do not believe this is a health and safety issue.

Posted By John_Webster It is normally the combination of clothing fabrics etc worn that causes the static. For example, multiple layers with alternate synthetic and natural fibres. It's YOU, not the equipment, that has the problem. The shocks are a nuisance, but harmless unless you are handling sensitive electronoc equipment. If you regularly touch poor conducting, but earthed material, like brick an plaster walls, you will discharge the static without the shock. Or wear gloves!!

I'm glad you have raised this issue, my local supermarket has recently undergone a major refurbishment which included the opening of a second level (access gained by sloped elevator), the second level comprises of a laminate type flooring.
I constantly receive Static electric shocks whilst i am pushing the trolley around on this level, the shocks are received whilst i am touching the trolley and i have rubber soled shoes on to. The shocks are not really a hazard for myself as i am a fairly fit young chap, but i cannot recall seeing any signage for people that have pacemakers etc.
I must admit though that i haven't actually reported the shocks to the supermarket in question, this is very hypocritical of me as i am constantly badgering our work force to report, hazards, near misses etc. I think i will send them a letter now.
The elevated slope can also cause problems, the trolleys are fitted with some kind of magnetic lock that locks the trolley to the escalator to prevent the trolley from careering down the elevators, however i have found problems with this too, including trolleys that don't lock correctly, luckily for me my trolley has been near empty when this has happened to me but the thought of a fully loaded trolley careering down the elevator into pedestrians is frightening. Has anyone else experienced problems with these? (sorry to change subject, but whilst we are on supermarkets......)
PS if anyone has a solution for stopping these shocks please let us know.
Many Thanks
Dean

Posted By Dave Wilson Interesting"!
As this happens to me all the time and trust me it hurts and even more so if you have arthritis as the unexpected sudden movement in an arthritic joint is excruciatingly painful to the extent that it some times drops me as though I have been whacked with a captive bolt gun!
Trolleys, Escalators or metal banisters are the worst and falling a couple of steps to a hard floor is painful.
That said I always land in a firing position.
This seems to be even worse in shops where they have a mixture of carpet and hard floors will this make a difference?

Posted By Ron Hunter In the interest of self-preservation , I recommend wearing gloves (leather/driving type are best). You may well still receive a shock, but the potential charge will be much reduced.Won't stop the static, but will protect you! Earthing straps on the trolleys would probably solve it for everyone. Keep complaining to customer services, encourage others to do the same. Static IS a health and safety issue, at least in a workplace context. Imagine if you will knowing that you are going to receive an electric shock every time you touch a metal filing cabinet.........the psychological effects are significant.

Posted By Alan Nicholls There you go Ron an excuse to start a new thread on Stress in the workplace.
Back to the plot in our work place several machines build up a nice hefty static charge.
With 2 rubber gauntlets a metal cabinet and ample air pressure. 60psi shot blasting is a game of Russian Roulette. If you allow the metal item being cleaned to lift from the metal screen while holding it, and the gun in the other hand. The ensuing shock does tend to wake you up quite quickly.
No risk of explosion or fire in the area!
Just tends to keep you on your toes.

Posted By Crim I remember reading in the old Fire Magazine (during the 1990's I think it was), about a woman who went to the loo and when she pulled down her tights there was a static spark which ignited methane in the toilet. She received superficial burns!
Please be careful if you visit the supermarket toilet as it may be you who is creating the static due to your clothing/footwear and the floor covering?.

Posted By Sovay Shaw Thank you all.
Let's see now .... Non-insulating footwear, non-synthetic clothing and wearing gloves (leather or rubber?), stockings (not tights), feeling my way round the outside walls and dragging a chain behind me?
You don't think it might be a bit kinky for Tesco Extra, do you?

Posted By David A Cooper Sad though this may sound my MSc dissertation researched accidents on escalators involving trolleys! During my literature search I came across an HSE document ref HS(G)84 of safe systems for trolleys. You might find something in it re static!

Posted By Doug Russell Even more sad, I still have a copy of HSG84. Its been out of print for some time. It is silent on the issue of static electricity and is mainly concerned with accidents and handling. The guidance was produced after the death of a child who was trapped in a trolley that over-turned

Posted By David A Cooper To mitigate my "sadness" I found that there had been fatalities involving trolleys on escalators and one owner/user was having a hospitalisation every 11 days from a trolley/escalator accident. As a result of my research the standards authorities reconsidered the update to EN115 so it did have some use! Even more interesting - I discovered that some trolley manufacturers derate the safe working load as soon as the trolley is on an incline! I do "sad" well!!!!

Posted By Bob Baynes Simple. Before entering the supermarket take a firm grasp of a bare metal part of the trolley and do not let go until you are outside again. You are now earthed all the time preventing the static from building up. Can cause some strange contortions when selecting some items but as long as one hand or the other is still in contact with the bare metal it does work!

Posted By Lilian McCartney Just some thoughts..
I've been kind of lucky and have only experienced this a few times. At the time, I thought it was a damaged trolley where the rubber wheel was touching the rest of the trolley thus building up the static - but that was only a guess - so I don't know for sure (once I get the chcoloate past the till everything else goes blurred). Other times was when I had on more synthetic materials than natural fibres.
Maybe a combination of both??

Posted By thomas satelle apparantly static electricity shock is caused by the amount of electricity you build up and goes unnoticed until you attempt to touch anything metal- electricity jumps across just as you touch the trolly. some people are highly prone to this.
what to do Before you shop next time take hold of a piece of metal or touch a piece of metal for a few minutes and the charge will run from your body into the metal and dissipate. there will be no static when you touch the trolly
Hope this does it sparky
