Can anyone help me with a quick fix? I am looking for a summary of practicle tips, precautions and practices to run some toolbox talks on for earthing and bonding practices. Does anyone have such a summary, or better still a suitable presentation? I just want to save some time so apologies for asking for others hard work.
This is as a result of a "near hit" (Just to keep Jim happy), we had on a solvent filling machine.

As HS Practioners we cannot be expected to be able to give lectures or instructions on every task that comes along.
Sounds like a job for the Electrical Engineer.

Hi Sarah
Please don't take this wrong, but if you are required to give a presentation about earth bonding of equipment to the persons doing the task then I submit to you that they are not competent to do the job.
First of all the complete system of the machines electrical supply needs to be checked to ensure that :-
1 It needs to be bonded - ie it is not double insulated
2 Any bonding will actually take it to earth
3 That in any fault condition the earth loop it continuous and actually generates the ground fault you're trying to get so that the RCD trips.
Personally I would agree with Steve and get a qualified and competent Electrician in and get him/her to do the job for you.
Sorry to be so negative but you just might find that you're dealing with more 230V, either way "Better safe than sorry" and you do not want to give incorrect information by mistake.
Cheers Kelvin

Is the issue related to earth bonding of the machines electrical supply or is it bonding to prevent a build up of static charge on the machines body??

If the machine is properly "earthed" to ground then it will also be earthed to static.
Surely.
If the machine is double insulated, then you will need to assure that it is earthed if it generates a static charge.
The instructions should state this.
In any case, your safety policy should state that "all electrical installations and repairs are carried out by qualified electricians" (sic)
Trying to teach someone "toolbox" electrical installation is a short way to lose personnel, permanently.

Thanks for the comments to date.
The issue is relating to the build up of static electricity.
For those of you who have pointed out I would not NEVER cover electrical safety in such as manner.
I failed to express my request clearly. I was looking for any practices which other companies have adopted such as informing staff to scratch the paint off of a drum before applying an earthing cable to ensure there is no insulation between.
We have several practices in place such as use of anitstatic shoes and testing thereof, use of earthing leads, limiting the surface area of insulating materials such as plastic screening, etc. I was interested to see if there were other practices, or if anyone had procedures or training that covered the control of static build up.
Just to show I am not a slip shod practitioner, I have had an extensive survey of flammable atmospheres and control of the ignition hazards done two years back. However I still find it difficult to get at some of the specific practices which can be adopted without trawling through many different publications.

You could try the petroleum tanker area for ideas as they have very specific methods for bonding of tankers prior to off-loading fuel deliveries and for filling tankers. The standards there are well developed but I am away from that particular issue now so I can't be more specific. As for toolbox talks, these should address the practice of what you expect done and demonstrations of it. If you can't fit the summary on an A4 sheet - it is too much! From your description of the topic, I think you may need some specialist input re the causes and control of static for you production processes, so that control can be well engineered and easily implemented by 'average' employees after the training. perhaps someone out there has some technical 'static' knowledge?
