Hi everyone...

I'm looking for some advice on LUX testing before I make any recommendations to my site manager, which could be quite costly. To give you a brief understanding of the working enviornment, I work at warehouse distribution centre which includes a transport yard with 17 dockable loading bays for artics/trailers etc. There is also a pedestrian walkway adjacent to the loading bays (around 25 metres in front of a parked lorries/trailers). Adjacent to the walkway, on the other side, are parking bays for trailers not likely to move frequently.

I conducted some LUX readings a couple of weeks ago (night time). Directly under the loading bay the readings are circa 18-22 LUX. When conducting readings on the pedestrian walking I was struggling to get readings of 1 or 2, I even had 0 in some locations.

In terms of actually standing there it didn't particularly look dark or in adequate lighting but I'm obviously concerned with the readings and if there was an incident etc.

I'm familiar with HSG38 and their recommended LUX levels. Given the working environment I was basing my readings on an average LUX of 20 and minimum of 5.

If anyone could point me in the right direction and or advise that would be great? I don't want to ruffle too many feathers as me suggesting to put some additional floor lights in will not go down well at all. I want to be 100% that my advice is correct and the lighting is, in fact, inadequate.

Thanks everyone!

The human eye is very good at adapting to lighting levels, particularly low levels of light.  If you go into a typical large office people assume the lighting level is the same all across the office but it can be 10 times brighter next to the windows on sunny day. It is only when you have to look at things in detail and you realise that your ability to discriminate objects is impeded by the low light levels.  A lux meter gives a true objective measure of lighting levels. The nastiest accident I ever had to deal with was in part due to low lighting levels in a document store. Nobody realised how dark it really was in there until someone had an accident.
