Hi all,
We've wracked our brains here and come up with some wierd and wonderful ideas about edge protection for ships containers which need repairs to the roof. Basically jobs can take as little as a few minuntes to over an hour to complete and while the worker is up there they can easily fall a significant height from the container.
Obviously the solution can not be too onerous on the worker as they simply won't do it...we're dealing with manly men who will take short cuts. The containers are open to the elements and can be in different areas so the solution needs to be portable.
I can't believe we're the only ones with this problem and would much appreciate if anyone has come across a similar issue maybe in construction where you need to work at height for a short duration and have nothing to latch onto.
We're looking at a post and barrier system but have looked on the net for a product that would lean itself to this and drawn a blank.
Any help would be great. Many thanks.

Hi Starbuck
I am assuming that you're UK based.
You have 2 main problems to contend with:-
the [under]stated lack of personal discipline of individual members of your workforce and sensible compliance with the WaH regs. I know how it works, there have been many container repair companies in my neck of almost civilised Essex for as long as I can remember.
You don't have any chance of achieving a defensible level of compliance with the WaH Regs until you deal with the need for individual discipline [and I don't mean just sack 'em; that's not acceptable nor even sensible for trained operatives]. Whatever you provide will not be used as intended unless you instil a far higher level of personal responsibility in all operatives.
As for how you can comply, there are several methods that will range for fall prevention [inspection & very short-term work] to fixed working platforms and everything that goes with them for longer term activity.
If you need more, feel able to contact me direct; just click on the name for the email address.

A method I have seen is a prefabricated edge (toeboards and handrails)that is made to fit on top of containers, different sizes for different sized containers all with lifting lugs, that were the crane lifted into position. These were local manufactured. But worked!!

Just thinking latteraly, can the containers be put on their sides so that the top now becomes a sidewall?
Obviously needs a safe working system for the tipping (I am thinking a crane can do this) and confirmation that the container is strong enough to survive such tipping.
Just a thought...

Thanks for the replies gents. We don't have a crane per se, we use a counter balance so the tipping isn't really an easy option.
Frank I'm aware about the behaviour aspect but don't like to rely on the human element too much, they being the weakest link is all. I prefer an engineering approach which doesn't give them too many options but to comply and where they do have to become part of the solution I want to make that part as small and easy as possible for them and not give them reason to violate procedures.
Looks like we're going to construct the post and rail stumps that will lock in the four corners, kind of like a tensator barrier works, only with much stronger cordans that people can fall against and not throgh.
Cheers again guys, appreciate the thoughts.

If you need a post and net solution that is portable, try Huck Nets in Bridport, Dorset. (01308 425100).
I have no connection with Huck, other than being a satisfied customer.

Have you thought of air bags, they are relativley cheap ligght weight and easy to put inplace, take mins they don't obviously prevent a fall but have see them use a lot lately stored on site at loading areas on many a construction site

I hadn't thought of that, good one, that may just work, but I guess the bags take up quite a bit of space when inflated and we're in a confined area with vehicle movement. Worth some thought though.
Thanks :)

If you would like to call me directly on 01785 850 333 or email me at richard@totalaccess.co.uk I can go through a couple of ways in which we have solved this problem for previous clients.
Your idea of the corner posts is one method,though we have a vertical anchor post that has been designed and tested to fit inside a docking point at the corners of the containers (now point re-inventing the wheel so to speak).
I look forward to hearing from you - Richard Hinckley

Hi Starbuck
I have a similar problem and would be interested in hearing how you are progressing also in pooling our thoughts on this. Please contact me either email or phone.
regards

Further to the air bag method. Why not consider the same bags that are in use on many roof build in the construction industry.
I have seen two types of flexible fall protection that has impressed me.
1. Bulk bags filled with polyfoam balls i.e. giant beanbags. Problem was it could get messy if these were split, as beans were too small.
2. Bulk bags filled with foam footballs, (best method I have seen anyway, just ensure you discipline the potential stuntmen)
Both of the above methods are much cheaper than airbags, take a lot less fixing up and can be transported anywhere on site without tying up the flt.
I must admit though, my first choice would have been to place container next to wall or similar and then move a specially constructed stand around the other three sides.
I am interested in what the end solution of this problem so please keep us informed as to what solution you found worked best.
Jason

Hi,
The airbag or similar approach won't work, it's a space thing, it's at a premium and it's always changing. To use them it would take a lot of rearrangement, which is fine, but if it can be avoided then I'd prefer it. Richard, I tried to give you a call today but you're out the office so I'm dropping you an email.
I have already created the specs for a prototype which we are capable of manufacturing ourselves and then testing if need be, but it would be nice if something was already available on the market.
Simon, Starbuck is only my name at the weekends when I'm fighting cylons, during the week you can call me Zoe < please see the humour in that and not the sad geeky side, I'm actually an interesting and involved person, honest!!!
Will keep you all posted and thanks for the ideas/replies.

Why not use a fall protection system with a harness attached to a 'Sucker' which you can reposition, place wherever you want and lenghthen or shorten the rope etc. we used them when working on aircraft wings, fuselage and the tails, works very well outdoors and does not damage the surface they are put on. Works with portable compresed air, the engineers loved them as they did not have to erect a full scaffold etc or work of MEWP. Cant remember the name but if you want me to find out then I will make a few phonecalls!

That sounds like an awesome idea, but I'm not sure it would work as a ships container roof isn't a flat surface like that on a wing. See picture in link below, it has ridges which are maybe 10 to 15cm wide and then dips. How wide is the device, do you think it would still work?

Can the work be carried out from the safety of a 'Cherry-picker'?
Just a thought.

Are all these containers the same size? If so could you build a permanent gantry or platform similar to a loading dock arrangement, which you park the containers between. This could have permanent edge protection, with gated access for staff and the open ends for the containers to get in or out. Granted the gap between the container and the platform would have to be such that no one could fall through and the system could introduce greater hazards with vehicle manoeuvring which may make it totally impracticable. If its not impracticable the top of the container would now be a safe place of work.

Its called 'wingrip' and is manufactured by www.latchways.com, its very good go and work well

Cheers am heading off to check that site out now. Unfortunately there is no way to do it from a MEWP or cherry picker and ships containers do come in a very varrying sizes. It's easy for us to build a gantry so that harnesses can be attached, but we can't always keep all the work at height in one area so it makes that solution difficult to work.

Hi Starbuck have you tried looking at advanced guardrails as manufactured by Turner access you can erect these whilst still on the floor.
