Light, like heat, noise, and vibration, can seem innocuous at first.  However, the characteristics of light in a workplace, its consistency, and its delivery can profoundly affect the health, safety, and productivity of workers.  Thus, workplace illumination warrants further investigation and, yes, its own series in “The Third Degree.”
     Many similarities exist between the human experiences of light and sound.  It likely comes as no surprise, then, that presentation of fundamental information in this series parallels that in the “Occupational Soundscapes” series.  Links between the two also exist, for example, when used in conjunction to increase the effectiveness of communication.
     These similarities and combined uses are explored, along with physiological and psychological impacts of lighting design choices and related topics.  This introductory installment provides a glossary of terms and, like those before it, a directory of published installments for convenient access to all series content.

     The Safe + Sound program is a joint initiative of several safety-oriented organizations to promote development of and broad participation in workplace safety and health programs.  In August each year, this year-round campaign boosts its outreach and recognition efforts by hosting a week-long event.
     Running from August 12 – 18, Safe + Sound Week 2024 highlights job hazard analysis, providing reference material and guidance to facilitate successful execution.  Nearly 4000 businesses, industry groups, educational institutions, and governmental bodies have registered for participation.  In addition to in-house efforts, some organizations also open events to the public.
