Narrow aisle trucks and personnel in the same aisle
Rank: Forum user
|
I am aware of German Ordnances concerning narrow aisle trucks and personnel working in the same aisle, in which one of two forms or protection is normally required: stationary protection or mobile protection (or a combination). Stationary is generally fixed sensors which can detect the presence of either a truck or a person, sending alerts to either (or both) to alert each other of the hazard. Mobile protection involves sensors just fitted to the trucks and alerts the driver to the presence of personnel. These system can be set up to do a lot more, but you get the gist: there is a set of rules and some technical interventions for Germany.
The question is, are there any such rules or official guidance for the UK? I certainly have so far been unable to determine anything other than the general guidance in HSG 76.
My specific situation is man-up VNA trucks, with personnel working as order pickers in the same aisle. No we have the warning beacons, headlights, horns, alerters etc. as some technical interventions and a range of organisational interventions, hand signals, etc. including the usual training, information, blah, blah.
Are there any specific rule?

Can I ask a simple question, do you perceive their is a risk of an accident of collision between the FLT/VNA and the foot worker?
If so then a local risk assessment would be the deciding factor, I'd personally advise against whatever, keeping segregation. Because, people become deaf to warning buzzers and horns and blind to flashing lights.

I have first hand experience of this (but unfortunately no control over it at the time).
Learn from the mistakes of others and don't do it. Rearward vision from a VNA is terrible at the best of times and forward vision isn't much better if the forks are loaded.
VNA operators have their hands full with operating the controls without having to be constantly worrying about where other people are. I don't know what models you are using but I'm betting they're 7 tons plus and shift at quite a rate. (ETX - K150's by any chance?)
Also, there is the risk of falling loads and stuff getting pushed through from adjoining aisles

In my experience it has always been a big no no to allow pedestrians down a VNA Aisle while a truck is in the aisle. If its the same ones we had the trucks are the same width as the aisle!
I would put a blanket ban in place that no pedestrians should enter an aisle with a VNA truck in it and vice versa, with some method of shutting the aisle of to trucks.

Agree with Mr.Flibble, there was a recent prosecution (some record company) and they got blasted lack of segregation, our policy is that no pedestrian enters the aisle where a VNA is operating or in the adjacent aisles. when the do enter a ailse to pick the chain off the aisle that they are working in and adjacent aisles to prevent VNA access.

Hi I have a lot of experience of VNA trucks. Segregation was the only way to ensure safety of pedestrians. The VNA truck is heavy and fast, with little of no ability for the driver to see foot pickers. There is also no where for foot pickers to escape too in the event of a VNA truck coming toward them. I would recommend plastic chains and signs across the aisles, backed up by safe systems, training and supervision. Simple rule - if a pedestrian goes into an aisle they chain it off to warn the VNA not to enter. Also, you may want to check on VNA trucks being used outside of narrow aisles. They still have poor visibility, but you can't use the same controls so you would need to keep their use limited to narrow aisles. Ian

Do you have a link to this prosecution dennish? Very apt timing this thread. Due to the extra work- we have the floor level of the racking as pick areas. Currently we keep the people out of the part of the aisle the flt comes in, and a minimum of two bays the other side of the flt. Also, two bays either side on the adjacent aisle. I have reported instances where this has not been adhered to- 'pressure of work'- slows the pick down as well. So I am getting some resistance from the management to enforce what we have already. Thanks Andy

Motorhead, I will look around to find it, but as i remember the picker was picking out of a location and and the VNA backed down the aisle without seeing the picker crushing them between the VNA and racking leg.

Not a VNA truck but same principle

Thanks for all of the replies, which sort of reinforces my need to get the warehouse to do more, but I find no compelling argument with which to reinforce my case - except to say that we should simply ban it because it is "not safe".
Of course I accept the Workplace Regs (17) would be made to apply, but even the HSE see that pedestrians in warehouses are a different matter. This para from HSG76 (para. 503):
503 Within the warehousing site, complete separation of vehicles and pedestrians should be the first consideration. Where complete separation is not reasonably practicable, other control measures need to be implemented. For example, it is not always possible to fully separate pedestrians and industrial trucks within warehouses.
Of course this does not mean that we should automatically permit pedestrians and VNA trucks in the same aisle - but the problem is that it does not guide us that we should not either. In later paragraphs, HSG76 goes on to describe methods (including the primary consideration of complete separation) of controlling risks when people and trucks must work together. Now bearing in mind that this guidance is specifically targeted at warehouse operation and not generally at "workplace transport", as is the workplace regs, then you may see where the resistance from the local management team is coming from.
In examining their operations, they have applied all of the guidance and their risk assessment addresses all of the factors that I would have. The only area where we differ, is that my assessment of the risk posed by the trucks is higher than theirs. Their resistance to change being that just because their own HSE advisor has a different opinion to mine, does not necessarily make him wrong, or me right - especially given that we are both seem to cite the same regulations and guidance.

VNA Trucks and Aisles are, however a completely different kettle of fish. You have a truck which travels down an aisle the same width, with the cab and operator 10 meter's plus in the air.
Tell the Management team to stand in an aisle as one of these trucks is hurtling down towards them. See if they change their minds then.
I used to drive one of these back in 1995 and even then pedestrians were not allowed in the same aisle.
Seperation of pedestrians and trucks with VNA aisles is completely practicable and possible and I'm sure that the HSE would agree. HSG76 is guidance. Nothing more and nothing less. HSE guidance will very rarely if at all tell you what you can and can't do, it merely suggests and cannot be taken as gospel.

Don't get me at all wrong, I fully understand the nature of the law and of HSE guidance. I also wish to influence change for the better in this situation. But using emotional responses such as 'you stand there and see if you change your mind', is not a well reasoned argument and not a method I employ when dealing with senior management.
Is there any best practice information, perhaps from the distribution sector on the subject? Retail is sometimes not helpful as it tends to look at risks in the front-of-shop movements where members of the public may be.

Seems to me your management confuse reasonably practicable with "a bit inconvenient". It must be at least 12 years since my involvement in such workplaces but segregation was standard practice for narrow aisle in the whole industry then.
So........ It begs the question "are your stores managers competent in their role" - it certainly sounds like they don't have much experience

Sometimes the 'you stand there and see if you change your mind' is the only approach that works. I have had to get them down to the Warehouse floor many times simply so they can appreciate the risk first hand. Getting them out of the 'product comes in, product goes out', 'I've got my KPI's' mindset is very hard. They do sensors the fit to the trucks which will cut them out if they detect pedestrians, Maybe that's the answer: http://www.modendiesel.i...elines_VNA_en_E_1012.pdf - page 39-40

I think it's more like the "bit inconvenient" view that is doing it. I did get the old story "but we have many picks from the aisles (pedestrians) and many put-aways (VNA) each day. Do you by how much a ban will delay operations?". My argument from that side was that this only served to increase the likelihood of an incident. It fell on deaf ears, with the usual retort: "But we have done it like this for the past 10 years without a single incident."
Fleeting thoughts of the "5 Monkeys in a cage" analogy passed through my mind...
I have seen the Linde document (thanks all the same ;-), which is where I got the bit in my first post about the German regulations - there was a fleeting hope that we may have something as specific as this buried away somewhere...
I think my best argument may be to restate the element of risk and my basic recommendation, but not to back them into a corner (I hate doing that) and advise them, as an absolute minimum, to invest in further technical interventions (i.e. as per the Linde solutions), augmented with further (and robust) organisational rules.
I get the feeling that on this job, that may be the best I can get.

You could try a back door approach. Speak to who does the warehouse planning for pick locations and layout. See if the stock can be moved to another location easily or if the pick flow can be changed, they maybe able to give you a sloution that you can put forward.
