Good morning all.

This is the scenario and it is common place:
We have a contract with a local water board as a main contractor, a large part of our work involves confined space to clean out wet wells, these average anything from 5 to 10 metres deep so a considerable risk once the lid is opened from a fall from height.
The issue is that a lot of these wells are located in a field with nothing around them, the tanker is parked away from the well due to the location. The confined space entry is via a standard set up of a tripod & winch, the problem is that we have no where to attach the top man to prevent him falling in, they all have restrain lanyards etc. bear in mind he has to look into the well to observe the confined space operative cleaning the well? WHO's responsibility is it for providing the means of a secure attachment point, the water company or us??

Thanks

Interesting question. It could be argued that like a building owner/occupier who installs and maintains/test eye bolts for window cleaners to attach to, the owner of the well has the duty here. Alternatively, as the employer, the duty to prevent falls is very firmly yours.

Given the environment, is it reasonable to expect the well owner to make this provision?

Is it feasible to use similar equipment to rock climbers for fixing a rope at the top of a cliff?

Ideally, this should have been considered at the planning stage and before the contract was finalised although I suspect that the reality of the safety procedures was not fully understood at that time. Certainly it should be a part of the renewal negotiations and costed for in the pricing.

As to who is responsible - ask yourself who would be prosecuted after a fall, Client or contractor/employer.

IMO it is you - based on the employer has the primary duty of care. The job should be subject to RA and all the necessary control measures put in place.

I would also say the water Board would have a responsibility to assure themselves that you as the contractor have all the necessary health and safety arrangements in place to complete this type of work.

As previous posts have commented on, this should have flagged up during the risk assessment, you should investigate feasability of putting in a temporary ground anchor. This would give you a secure anchor point near to the well opening.

I would probably say both - you to other persons, them to their employees. But would you really want to put this to the test! Remember that the solution (whatever you come up with eg ground anchors) is likely to require some form of long term commitment to evidenced maintenance.

This should have been sorted at the contract negotiation stage

It sounds like U are dumped with the problem as U are the employer - get a 4x4 reasonably close and tie him to that which is a perfectly acceptable way to go

Am I missing something here?

You have installed a safety tripod or quadpod over the chamber to provide a fall arrest anchor. Many of the tripods/quadpods have additional rated attachment points and are designed to cope with more than one person (for assisted recovery etc.).

If you choose the right tripod and properly anchor it, why can't the top man use it as a fall arrest anchor?

In other situations I have seen steel weld-mesh panels placed over an opening to prevent access (in this case falls) whilst still allowing vision and ventilation.

You could use 2 spiral anchors such as:

http://www.homedepot.com...-ANCFR16-ORG-A/202703690

to anchor into stable ground. Obviously the depth and soil type may effect the max loading.

For a more permanent solution ou could try and bury - http://www.concretebuild...nt/concrete%20weight.jpg

Suffice to say I would test either solution with a relalistic weight and dop height before using it myself ;-)

Thank you all some very interesting views, especially the temporary spiral anchor, will look a bit more into that option.

I do advocate that use of a trannie van to tie off people so as they cannot fall - its cheap as usually a trannie van is already on site and the HSE are OK with the practice as its suitable and sufficient and common sense when done properly whilst demonstrating that H&S does not stop jobs and is a benefit to a company

http://www.spirafix.com/ ground anchors are well worth a look if you are considering that option. I have used them (in a non work context) and they are incredibly easy to use. Very helpful sales people, lots of different sizes.

Shaun, if you use the screw in anchors, do not forget that you will need to scan for underground services!

Thanks Madge and Bluenose good points, and John M yes the water board or water company you could say which has 100's of assests in our area which we are contracted to clean and tanker.
