Workplace Lighting & OHS: Why TS EN 12464-1 Matters

Inadequate workplace lighting hurts both productivity and safety. A SOREAS guide for Bursa in the context of TS EN 12464-1:2021 and the Workplace Buildings Regulation.

Lighting is often overlooked — yet inadequate lighting both lowers productivity and raises the risk of accidents. And it isn't a comfort matter; it's a regulatory requirement.

The Legal Framework

Turkey's Regulation on Health & Safety Measures in Workplace Buildings ties workplace lighting directly to the TS EN 12464-1 standard (Article 22). In other words, inadequate lighting is also an OHS non-conformity.

What TS EN 12464-1:2021 Says

The standard defines minimum values per type of work area:

  • Em (illuminance): the minimum lux the task requires
  • Uo (uniformity): even distribution of light across the area
  • UGR (glare): the limit for disturbing glare
  • Ra (colour rendering): colours appearing correctly

An assembly line, warehouse, office and laboratory each need different values. "It looks bright enough" is not a measured conformity.

What SOREAS Does

  • Assesses existing lighting with a lux measurement
  • Reports conformity against TS EN 12464-1:2021
  • Where inadequate, offers a solution via luminaire selection and layout
  • With energy-efficient LED conversion, meets the standard and lowers the bill
