We've had an incident where a cherry picker (not sure which part as yet) had a fault with it.
The operative was in the bucket part trying to fix it, when it malfunctioned and started lifting.
He panicked and jumped out, not even looking how high up he was, and consequently has broken his leg!
A couple of things:
1) In normal operation it is usual to wear a safety harness, is this documented anywhere in any guidance notes? (you know Management, always like to know where!)
2) Advice/comments on being in a bucket and it malfunctioning and lifting? Is this feasible, do they have over ride functions which take into account possible malfunctions?
3) Would you expect an operative to wear a harness in the bucket whilst on the ground?
Any other thoughts/opinions would be welcomed to help me think this one through!
Thanks, B

Oh, and just to add to that, lone working? yea or nay?

Sorry, another thing, do cherry pickers have to be dual controlled, i.e. in basket and on ground in case of any eventuality?

Hi Brenda
Guidance on emergencies associated with MEWPs has been published by various organisations. For example, “Preventing falls from boom-type mobile elevating work platforms”, published by HSE comments
“Ensure you have a rescue plan agreed and in place …. Are trained people and rescue equipment on-site? Do all operatives understand what to do?”
Similarly, in Section 9 of “Construction Health & Safety”, published by the Construction Confederation, they comment
“12. MEWPs are fitted with emergency (auxiliary) lowering controls and an emergency stop switch. Before using a MEWP the operator(s) and another responsible person on site (who is not working on the platform) must know how to use the emergency controls.”
So the implication is that need someone at ground level to assist with an emergency, though might have other duties nearby.
General expectation that harness should be used when elevated. Exceptions to every rule e.g. working over water where it may be preferable to fall out in the event of overturning of MEWP.
Regards, Peter

Hi Peter,
Yes have since found the first reference material you mention, which is what I plan to start a risk assessment from.
However, if anyone has an assessment for working with cherry pickers that they would be willing to share with me, I would be greatful!
Thanks

Training on cherry pickers and scissors lifts would have answered your questions
Please please please please don't take it the wrong way but It would be benificial for you to do an IPAF course, on SL Boom Lifts course are dirt cheap too

Possibly, and not taken the wrong way, but in the mean time, i.e. now, I just needed some thoughts from those that know more than me sent my way!
I've had a look on the construction federations website at the document you have quoted from and typically it's under construction! No pun intended!

Hi Brenda
I agree with an earlier comment in that you should if at all possible do the IPAF course. It is very good and puts you in an incredibly strong position to identify good and bad practice amongst a workforce and contractors.
Is the machine hired? If so get the supplier in ASAP to do an investigation on the mechanical/electrical/hydraulic fault. If not get one of your own competent people to analyse the problem, making sure there is a bottom man to bring the basket down. Of course the E.stop should be checked in the basket and on the chassis.
A broken leg will have to be reported and as it is a slip, trip or FALL you might well get a visit. Having all your investigation, risk assessment and countermeasures in place will put you in a strong position. HSE, as we have said on here before, are a bit thin on the ground so if you are trying to do the right thing they will likely more or less leave you to get on with it.
A good paper trail will also help with the "inevitable" claim the chap will put in. A bit rambly I know but a start.
John

Brenda H,
Some good advice has already been given on the forum, however in order to help answer your questions, by bucket you mean the cage or basket ? There have also been very good threads on this same subject in the past and a search may reveal good information for you.
1.Always wear harness and clip on before elevating.
2. Buddy system is good as another pair of eyes are looking for hazards.
3. Not necessarily one would think but with the vision of hindsight - if that person is going to service repair and check this machine then they need to take it aloft and rehouse it to test and check. The person should be trained in its operation and working at height, be wearing a safety harness and should know what emergency procedures to follow in case of a malfunction?
Obviously he had the vehicle running when he was working on the controls - perhaps he should have fixed the problem first and then tested from the remote controls at ground level?
Another recent accident
It has been reported that a 33 year old maintenance worker was killed when he fell from an elevated work platform at 11:30 yesterday, Monday 23 April 2007.
Another worker was also injured in the accident and was taken to hospital.
It appears that the elevated work platform vehicle has tipped over while the men were on the platform which was in a raised position.
Police are investigating the accident
Hope this helps

Having maintained and operated plant in the past (some 20 years ago), can I add that the maintainer should have made sure the batteries/starter motor (if mechanical) should have been disconnected before it was worked on and that the person should have been trained to work on it. This should have been in the procedure for taking the access platform out of use for maintenance and what checks should be made to make sure it cannot move under maintenance. Except for testing.
As buckets can be quite high when in the parked position, fully down (depending on the size of the access platform), the Working Height Regs should be consulted for a good indication to say if a harness was required or not. I would say that in carrying out maintenance, a user may well have to climb around the said access platform and thus may fall even from its parked state.
I hope this is of some use.

Hi, me again. More good stuff has been posted after my last entry and one thing which I forgot to mention is that these machines have massively torquey motors. As a result simply putting a chock in front of the wheels will not necessarily stop it moving.
I have seen one climb over a chock which had been left inadvertently in place. The basket was sitting at what we considered driving height, about 10 feet up so the driver can see forward over the unit. The machine had a very long boom and the turning moment was so viscious that the basket put a big gouge in the roadway.
Our drivers always wore harnesses even for driving and fortunately he was shaken but not thrown out. Over a coffee later he told me he had experienced weightlessness as the basket dropped and something else when it came back up to meet him a second later.
You can get a similar effect going over speed ramps. Treat them with great respect.

Hi Brenda,
Firstly I hope your chap is recovering well after his fall / jump ?
I would be interested to know if you have any further details since your initial posting so as to give a clearer picture of the whole incident ?
It does seem highly unusual for a MEWP to begin lifting "on it's own" as there are a number of safety systems built in - dead man trigger or foot pedal, emergency stop etc.
Generally, maintenance personnel who are carrying out "live" adjustments in the basket would have a thorough understanding of all control systems and the potential affects of any adjustments or temporary over-rides !!!
As for the harness issue, as others have mentioned it is strongly recommended that a fully body harness combined with a short length (or adjustable - adjusted to be as short as possible) RESTRAINT lanyard is used at all times whilst in the platform (boom type MEWP's) - regardless of height of elevation. I would be happy to expand further on the harness element if that would be beneficial.
I hope the above comment is of use / interest.
Best Regards,
Alan

For me the key point about your posting is that an operative, who clearly had no real understanding of cherrypickers, was attempting to fix it. This then poses all sorts of questions concerning supervision, management and training.
Any use of a cherrypicker should never be "lone" as the normal emergency procedure is to use the controls in the machine body itself to lower the arm. I really am against reliance on descent ropes etc unless totally unavoidable. The dual controls are as far as I understand, universal on all plant of this type, including scissor lifts.
No person should be operating such a vehicle without proper training by such as IPAF, or similar. This training is NOT the same as the familiarisation training provided by the supplier or hire company.
I am sorry to say that in view of your lack of knowledge with these plant items you really are not in a position to do a risk assessment. You do not appear to have competent trained persons to either use or assess any task involving thir use. Hence assessment is simply that the risks are high and uncontrolled thus we should not utilise them.

Right, got a little more info.
By bucket I mean basket!
The machine is owned by us, i'm waiting to confirm what the maintenance arrangements are, but these are likely to be in-house.
The guy who fell is still in hospital and unavailable for comment at this stage. So what actually happened I don't know as he was lone working!
I suspect that the basket malfunctioned or something happened and he thought he would 'give it a go' at sorting it without bringing it back to the depot.
Is it usual for these vehicles to have dual controls for the bucket, i.e. in the bucket and at ground level?
Also, is it usual for two people to work with these vehicles so one person is always on the ground to control the bucket in case or emergency? Or is lone working acceptable? (sorry if dim question)

Hi Bob,
Thanks for your reply, i think we replied at a similar time so my posting was not deliberately ignoring what you had said.
I'm not proposing to carry out the risk assessment on my own, but with a trained operative, my name is not going on the assessment either.
My questions were really seeking further information/clarification on points so when I contribute to the assessment, from a H&S perspective, I am a little more informed about the work activity.

The IPAF course you talk about, is there a general awareness course or something similar?

Hi Brenda
as i inderstand it they should be inspected by a trained person every six months (insurance inspection) and should be serviced by a trained service engineer for this equipment. It's common practice to wear a harness and a second person should be present to operate machine from the ground using emergency pump valves which releases the hydraulic pressure slowely.
has the operator recieved any training on how to use this equipment. I done a one day training course.
Risk assesments should already be in place before use of the equipment and also for the task being carried out.
My view is that your company is not in a good position you would need to work hard to show you have learnt from this incident and putting control measures in place training courses, risk assesment etc.
Hope this helps

Do a google on the International Powered Access Federation and take it from there, they will quickly assist on training.
The fact that it is your own plant, you are maintaining it and the requirements for LOLER, it is lifting equipment for persons, apply then all sorts of alarm bells are ringing for me. I think you had better go through the maintenance records, the six monthly testing and inspection records and both operative and maintenance operative training and assessment etc in very sharp order. If you cannot confidently evidence competent persons, records of maintenance and testing and six monthly certification then I would suspend all use pending further review and action.

Hi Bob,
We carry out a certain amount of maintenance in house, but not the 6 monthly loler checks, these are done through our insurance company by a company authorised by them.
I have been on the IPAF site and got a list of local course providers.
It would seem there isn't a general over-view course, I would have to go on an operatives course, which I don't mind doing.

Hello Again,
As others have stated it would be highly recommended for your operators to be trained to IPAF standard not only on the specific types of MEWP's which they operate but also on the safe use and inspection of harnesses - the combination of the two courses would then ensure that they are fully familiar with all aspects of safe use, pre-operation inspection and emergency / rescue arrangements required by current legislation and industry standards.
IPAF also offer a training course for managers run through s selection of accredited centres.
A further avenue of enquiry may be to speak to some of the manufacturers about training available for maintenance personnel - this would tackle things on the technical side, complementing the operator training in proving employee competence.
I hope things work out OK on all fronts.
Regards,
Alan

Have any of your guys received training on use of cheery pickers. part of their training covers safe use and maintenance.
As said above if your guys a lacking training and no risk assessment then you may be better off suspending all use.
Phil
