Can anyone offer some info on allowing workers to climb out of a mewp to access a 30ft roof?
I witnessed this and stopped the job, trouble is now they are asking for the guidance doc that states you can not do this
I have checked the HSE Information Sheet MISC614 and it only mentions
“People climbing out of the MEWP (this is not normally allowed)”
I ask not allowed by whom?
Help please
Jai

If it is possible for them to fall while doing it, section 2 of the HSAWA 74, and the W@H Regs
If it is not possible for them to fall while doing it, and not possible for them to fall whilst on the roof, and not possible for them to fall while getting back into the MEWP, then I don't know of a prohibition.

i have since found this document HSE Information Sheet MISC611
it states
access or leave the cradle other than at ground
level or a designated safe access point;
l enter the cradle from over the parapet unless your
harness can be attached to a secure anchor point;
l attempt any reckless or dangerous practices, eg

You won't find it because it does not exist.
Was it a cherry picker or a Scossors lift with a platform extention. I can be done safely, eg extent the boom to an area greater than 2m from the oen egde or at a poitn where a suitable structural anchor can be attached to before leaving the platform/basket.
I'll dig out the HSE guidance that suggests this method, something to do with chainsaws and tree surgery i think
I'll get back to you soon!

sorry should have said
Don’t:
• use the SAE in adverse weather conditions, eg high winds, against manufacturer ’s or expert advice;
• access or leave the cradle other than at ground level or a designated safe access point;
• enter the cradle from over the parapet unless your harness can be attached to a secure anchor point;
• attempt any reckless or dangerous practices, eg rocking the cradle, dropping equipment to colleagues on the ground, taking friends ‘joy riding’;
• by-pass any safety device incorporated in any part of the system;
• overload the cradle beyond its safe working load (SWL), eg extra materials or people.

"Designated safe access point"
Dare i say it...... i hate saying this and i don't mean it to sound patronising, do a risk assessment to determin a safe access point

i have i stopped the job, they don't agree with me
they think it is safe to climb out 30ft in the air and step onto a roof with no fall protection and not hooked on,,,they are looking for my reasons in print from the hse etc
but i have found limited information as usual
MISC611 guidance states
don't access or leave the cradle other than at ground
level or a designated safe access point; what is a safe access point whilst in thew air?
please provide info to show these clever people

Look at the work at height regs
but rather than stop it why not speak to them and develop a safe system of work. Try and educate these clever people

I have seen this very successfully done by fixing two scaffolding tubes to extend across the front of the mewp cage
The mewp is then positioned just onto the roof.
You have then a narrow strip protected where a worker can walk with harness and have limited edge protection. All work is well within the confines of the protected area.
Probably suited for small inpection type jobs rather where full scaffolding would be expensive.
Providing the 'skilled & trained workman' stays within this you have the protection of edge protection and a harness. (Not suitable for fragile roofs).

Belive me i have tried
the first time i spoke to them nice and tried to resolve the issue, i was told "thats it we do not need to go onto the roof again", guess what i catch them again
we all try to do jobs quick and easy, some people want eductaion others don't, these are contractors on site, thier system of work do not mention accessing our roof, because if it did i would have asked for a roof access permit to be given to them, i would also ask for a risk assessments from them
Job Stopped until we find a safer way to complete the task, might as well of done the job myself

Ask them for their assessments of the risk from climbing out of a MEWP at height and onto a roof. Ask what they do with regards to edge protection and fall arrest from the roof. Ask what would happen if they were half way between the MEWP and the roof when a gust of wind comes and rocks the platform. What happens if the MEWP is accidentally moved (collision or other situation). If you're not happy with their response, then highlight their shortcomings. If they continue to be problematic, then kindly ask them off site, and contest their fee - the law requires a job to be done safely. If they can not complete the job safely and you are not satisfied that they will be able to do the job safely, then use this to contest their fee (or part thereof).

Posted By Expat Safety Contact IPAF www.ipaf.org as they are the leading body in powered access and will be able to provide you with the information that you require. I can advise you though that when receiving the training you are informed that it is not permitted to leave the basket and I believe this policy is adopted by most of the respected construction contractors.

The easy solution is to consult BS 8460, para 6.11, and if you still wish to proceed, refer to the proposed Risk Assessment given at Annex C.
Note however that few if any Manufacturer's Operating Instructions refer to the MEWP being suitable for entering/exiting the platform when elevated, and the prohibition on doeing so is mentioned in EN280 7.1.1.2
It would be a bold Assessor who ignored all the above.

Steven Bentham describes a system which I have allowed on site as recently as this morning. I was sceptical initially and suggested a tower scaffold be used. We discussed the options and as paint tins (lots of them) were involved and hence a lot of carrying and lifting, I asked to see the system in operation.
The end platform of the scissors lift MEWP was extended at height over the roof and the guard rail folded flat. Extended side rails preserved the safe area. It worked a treat and allowed a safe place of work whilst restraint ropes were installed.
Another advantage is the total lack of a tower for kiddies to play on if they came on site because the MEWP is moved elsewhere after work ceases.
Having said all of the above, I would never allow a cherry picker to be exited at height.
