Have any of you heard of the recent training input stating that fall arrestors do not need to be worn in scissor lifts or MEWPs’. Reason being given is that if it topples over the person attached to the equipment via his fall protection is more likely to be crushed than one who is not attached.

It doesn't add up in a number of ways including the fact that there is at least as much chance of injury or worse when falling from a toppling MEWP.

Your opinions would be appreciated.

coy Tanger,

yes I have come across this argument a number times. However Fall Restraint is required so operatives can't get out of platform (not fall arrest). Its a bit like wearing a seat belt when driving a car!

Hi,
Not aware of any changes in guidance : IPAF and HSE links should clarify:

Think that's fun?

Try the older argument in docks (using MEWPS to paint and service ships) which do you put on first - the auto inflating lifejacket then the harness, or the other way round? one negates the other!

Great argument until the harness/lifeacket combo was invented.

BTW I never did find out if the newton bouyancy was sufficient to class as a lifejacket under SOLAS 74.

Yours aye

Coy
dont use fall arrest, use fall prevention ie restrain the operator so that he cannot fall out, arrestors are a last resort.

I have not seen any authorititive evidence suggesting that fall restraint worn by MEWP operators increases the likelyhood of serious injury in the event of an overturn.

It is probably gossip opinions of the operators as they do not like the rule

I can recall an incident several years ago on the construction of Sheffield Law Courts where 2 people were thrown out of a MEWP killing one. The cherry picker operator tried lowering the MEWP when it snagged on a window ledge. Instead of backing off he tried to force the basket past the ledge causing the wheels nearest the walls to lift off the floor. As the basket slipped past the ledge the wheels banged to the ground causing sufficient recoil in the cherry picker arm to toss the 2 men out of the basket.

The fall restraint rule would have prevented this.

Hi

I have had this question posed to me, after looking into it I found that there are two issues here
1. Fall arrestors are not required in scissor lifts as they have the edge protection and you can compare then with tower scaffolds.
2. MEP (cherrypickers) require fall protection to protect the occupants against the "catapult" effect if the MEP is driven over a bump, uneven ground

Regards

With scissor lifts I would accept fall arrest is not much use

Fall arrest does not prevent a fall from height, it stops you hitting the floor but you will probably still be injured, and left dangling in a life threatening situation.

Also I would not ask for fall restraint harnessess and lanyards in MOST scissor lifts "even when travelling" But we must assess each MEWP as there are a wide variation of design and with some I may propose that restraint should be worn when travelling.

With regard to edge protection this is provided on cherry pickers as well as scissor lifts
regards
Steve

If anyone is interested in self check MEWP and/or harness tagging and inspection systems drop me a line as we have developed an innovative system which may be of interest. As with most equipment, prevention is the key - by checking the equipment for faults before using it can cut through the assumption factor - "it was fine yesterday so it will be fine today".

First port of call read manufacturers instructions see what they recommend. Other issue most operatives in cherry pickers do not use the provided hook attachment point, usually they are connected to the top rail using fall arrest equipment. Industry in general do not know the difference between fall arrest and fall restraint.

The anchor points fitted as standard to the cherry pickers I have seen are for restraint only. They are not suitable as fall arrest anchor points.

A further point to note is that if fall arrest is being used then rescue arrangements should be prepared and at hand in the event that the arrest system is deployed ie we cannot leave the person dangling there.

There's a BS Code of Practice covering this for MEWP, unfortunately I don't have a reference to hand.
The jist of the CoP:

Restraint only mandatory where there is a risk of collision. ( I would include travelling in a scissor lift within that risk).
When working over water in a MEWP, lifejacket to be substituted for restraint.
The CoP also describes the circumstances when it is permissible to climb out from the basket of the MEWP.

db: I trust the suggestion that a combined harness/lifejacket has been invented was intended in jest.

Yes db, the 150 N floating safety harness has been a revelation - especially good for working on slip at seaward side of pilot/tug during maintenance. The newton value is sufficient if the work is being done within controlled waters / harbour limits. Not sure about offshore, i'd expect 275N but not available in UK yet with regulatory approval...

Thank you Garfield,

You know it with the 150 - re: the 275 it will be back to spray hood/light/whistle posture in water etc.etc.

Have you experience of these? and how are they inspected under SOLAS 74/Puwer at sea or both and the periodicity?

Yours aye
