Photobiological Safety Training Workshop

Training Workshop: Photobiological Safety of Non-Laser Sources of Optical Radiation

In placing products in the UK (or EU) markets, the manufacturer or distributor has a legal requirement to satisfy the essential health and safety requirements for UKCA (or CE) marking. In the case of products including non-laser source(s) of optical radiation- whether the emission of optical radiation be the primary purpose of the product or not- the photobiological safety hazard should be evaluated.

EN 62471 provides a framework for hazard assessment, risk group classification and general guidance which has been used as the basis of application specific product standards. Such product safety standards include IEC TR 62778 for lighting applications (implemented by the luminaire standard, EN 60598-1) and IEC 62471-5 for image projectors. For some groups of products, such as electrical products for laboratory use (EN 61010-1) or medical electrical equipment (eg. EN 60101-2-57), implementation of EN 62471 is required. In all other cases, EN 62471 should be applied directly.

According to EN 62471 electrically-powered sources of optical radiation are classified into four risk groups subject to their potential photobiological hazard to the human eye or skin. The classification requires that a spectroradiometric measurement of the emitted light be performed.

Pro-Lite’s photobiological safety training workshop will steer you through the steps necessary to comply with the regulations, including practical guidance on how to perform the spectroradiometric measurements, the selection of appropriate measurement equipment, how to calculate the optical radiation hazard and how to assign the appropriate risk group to the product.

This workshop is essential training for anyone responsible for compiling the technical file necessary to comply with UKCA regulations or EU Directives for CE marking.

This workshop is aimed at manufacturers of lamps, luminaires or any product containing non-laser sources of optical radiation, and will be highly relevant to technical product managers, laboratory engineers, regulatory affairs managers, quality managers, product safety managers and any individuals who are keen to learn how photobiological safety standards may affect their business.

Dates: Course dates

Times: 09:00 – 17:00

Location: Online (via Teams)

Workshop Tutor:  Leslie Lyons

Leslie Lyons has a wealth of experience in optical radiation measurements, having been involved in the development of photobiological safety standards. Leslie serves on the BSI technical committees EPL/76 “Optical radiation safety and laser equipment” & CH/172/6 “Ophthalmic instruments”. He also serves on IEC TC 76 “Optical radiation safety and laser equipment” & IEC TC 34 WG6 “Photobiological safety”.

Fee:

This eight hour workshop reviews the hazards to our skin and eyes from artificial optical radiation as well as the legal framework that applies to employers and manufacturers of lighting products. The measurements and calculations required by EN 62471 to assess the photobiological hazard associated with a light source will be presented and the steps required to assign the product to one of the four “risk groups” reviewed.

§1.0

Theory of Photobiological Safety

  • The optical and thermal hazards that light from 200-3000nm presents to our skin and eyes
  • The legal framework for photobiological safety as it applies to employers and to manufacturers and suppliers of any type of lighting product
  • The simplified analysis for white LED-based luminaires – the blue light hazard
§2.0

Practical Measurements for Photobiological Safety Calculations

  • Spectroradiometric measurements of irradiance and radiance
  • Applying the EN 62471 hazard weighting functions
  • Special test conditions for GLS sources
  • Special test conditions for recessed light sources – sources used with lenses or reflectors – and the need to establish the apparent source size and location
  • Calculation of the EN 62471 risk group
  • Labelling and supporting documentation requirements for the four risk groups
  • Testing the “worst case” light output
