Lux levels for health and safety...

[sythai]

Morning just sorting out an estimate for a lighting upgrade.

Commercial premises so have been informed will require 400lux min at floor level.

All I'm after is where it actually states this (H&S at work doc?) so I can state it on the estimate for the customer to refer to...?

Many Thanks,

Sy

Sy,
It comes from the management regs and the welfare regs.
Try HSG38, though the SLL/CIBSE Code for lighting, may be a better start.
400 Lx is very high for general lighting at floor level, however, the customer is King!

It can also depend upon what the commercial premises is going to be used for that they have requested this minimum lighting level.

Thanks chaps...

Being used as a hairdressers.... It was wholesaler that done me up the lighting design... So do you think they may have over estimated the required level a bit. Wouldn't surprise me! Customer hasn't got a clue about lux levels, just want to make sure she is covered against if anything went wrong and the HSE were involved,

Cheers Sy

Here's some info from the HSE's website:
Lighting Levels
Further detail (page 27)

Also Document L Building Regulations need to comply.
Part L requires that energy efficient lighting be used in both domestic (Part L1) and non-domestic (Part L2) buildings. The regulations currently apply to all new buildings and refurbishments of over 100m² floor area. The document provides design information in the following areas for non-domestic buildings:
• Effective use of daylight
• Selection of lamp types
• Associated control gear and power factor correction
• Luminaire efficiency
• Use of lighting controls
[FONT=Arial,Helvetica,Geneva,Swiss,SunSans-Regular]The requirements can be met by selecting an efficient lamp, control gear and luminaire performance combination, along with lighting controls that make maximum use of daylight and avoid unnecessary lighting during times when spaces are unoccupied.[/FONT]
[FONT=Arial,Helvetica,Geneva,Swiss,SunSans-Regular]Lighting controls can be simply an increased use of switches, time clocks and photocells to turn luminaires on and off. More advanced solutions include using high frequency dimmable control gear linked to photocells to provide constant illumination and daylight linking. Intelligent luminaires, such as Intellect, provide a straightforward solution to providing lighting control with user selectable functionality.[/FONT]
[FONT=Arial,Helvetica,Geneva,Swiss,SunSans-Regular]It is strongly recommend that reference be made to the current edition of Approved Document L, to ensure compliance with the latest requirements. Full details of Part L can be found on www.communities.gov.uk.[/FONT]

Thats great thank you very much chaps.... all the info I will ever need there for lighting. Ideal because now I've got something I print off for the customer. Looking at HSG38 my 400 level I dont think it will be too far off the mark, better to over estimate slightly anyway.
