Posted By Elliot Morton Hi We use man baskets to repair jetty's and personnel transfer from barge to jetty. The recommendation is that the anchor points are in the base of the man basket and a short lanyard to prevent personnel falling / climbing out of the man basket. Following with discussions with our employees they say that in a catastropic failure of the crane or barge that if the man basket is in the water, that the short lanyards should be hooked to a short strop above their heads so that they can released it in an emergency. The same thing but different? Comments / views please Regards Elliot

Posted By Dave Merchant hmm... I can see their idea, but question if the basket would stay afloat for long enough to allow a lanyard to be disconnected no matter where it's clipped. It also assumes that this 'failure' results in the man basket hitting the water the right way up! If you're working entirely above water then there's a sensible argument for not having a restraint system at all, and just wearing life jackets. IPAF's guidance on working over water is worth reading, as they have the same problems and specifically say "no harnesses". I wouldn't work over water with a connection to ANYTHING that could fall in and doesn't float as well as I do. As once said to me about driving across frozen lakes with your seatbelt on:- It's better to jump out and swim for it, than stay in and sink with it.

Posted By Elliot Morton Hi Dave The lads wear inflatable life jackets over the harness's as normally the client specs it in their requirements "life jackets to be worn" But our training provider says that the harness must be clipped to an anchor point low down / floor level. It appears to be a grey area? regards Elliot

Posted By Dave Merchant It'll only be a gray area until someone drowns. I suggest talking to your training provider and asking for an explanation as to why they say what they say - blindly following generic training is not going to work in a case-specific situation like yours, and while there's no specific law on working over water the advice from IPAF is very clear. If you're in need of something more 'official' than that, I suggest you contact the HSE Infoline. They won't give you an absolutely precise answer but they'll describe what general principles of protection they would expect you to be using.

Posted By CFT Elliot Not grey in my book, no form of harness would be worn whilst working in a manner such as you suggest as long as it was 100% over liquid; clearly the scenario you present is not and it is therefore not quite so simple. As it would seem this is for transference and I would assume the basket is probably around 1200mm to 1500mm at guard rail height frankly there is little a restraint lanyard is going to do anyway; as they are being transferred they are not moving and should a tip or breakage occur such as you describe then again the lanyard will be about as much use as a wicker canoe to rescue them with. All the best CFT

Posted By alex mccreadie I would agree with some of the posters in "no harness" If you are dealing with people that say harnesses must be worn then in my opinion your workforce have got it right. Connect the lanyard to the crane hook and then clip on to that. When I was involved with mobile cranes that is what we taught. BS7121 PART 1 says to connect to a suitable point within the carrier but this is a best practice document. In this case I feel your operators are correct and would go with them if harnesses must be worn. MY OPINION Ta Alex

Posted By David AB Thomas HSE's MISC614 states: Working near water When working next to water, a harness should not be worn due to the risk of drowning if the MEWP falls into the water. Life jackets should be worn.

Posted By Dave Merchant If someone other than the HSE (trainer, site owner, primary contractor, etc.) is insisting on the workers wearing a harness, then it's THEY who are most likely at fault, either through a simple lack of understanding or a mistaken reading of the regulations. If the workers are competent users of PFPE then part of that competence is the ability to understand when instructions they are being given are wrong, and when they should refuse to follow them until a detailed re-evaluation of the risks and possible solutions has been carried out. Assuming that just because someone is 'in charge' makes them immune to mistakes kinda misses the point of why we've just adopted the CMA. Anyone with a kid has used the line "I don't care what HE said - if I told you to put your hand in a fire, would you?", but it seems they forget it when they arrive at work.

Posted By Elliot Morton Hi Thanks for all your views on this matter. The trouble is when you are working on a steel pile top, or steel work from a man basket and a vessels wash (swell or wave from a vessel that has passed by long before the swell reaches you). and then the barge moves on the swell and the pendulum effects takes over with the crane jib. Then the ride in the man basket can be quite rough and I am concerned about the employees either falling out or the man basket suffering damage and the employees falling on to the steel work or into the river from a long way up. regards Elliot

Posted By safety medic Elliott, From you last post I would like to pick up on one point. Irrelevant to what the Client/PC says, if a completed risk assessment that is inline with current HSE guidance is conducted then you have a SSoW. You rightly point out that there is a bigger risk of someone being thrown out of the basket than the basket/crane actually failing (provided all the controls are in place) therefore harness is a suitable control. You dont specify if the basket is open top (no roof) if so, the option is to attach to the crane hook/master link with strop/inertia. As a result of your risk assessment you will be able to identify the major residual risk and find a suitable control, the anchor point, quick release buckles etc.
