In 2018, ACGIH® published on the Notice of Intended Changes, a statement on the occupational health aspects of new lighting technologies. It describes the circadian, neuroendocrine and neurobehavioral effects of light. Over the past decade a revolution in indoor lighting has been underway, fueled partly by the new technologies of compact fluorescent lamps (CFLs) and solid-state, light-emitting-diode (LED) lamps, and partly by efforts to reduce the consumption of electrical energy. Do these changes in the work environment pose any health concerns? The ACGIH® TLVs® for Light and Near Infrared Radiation for evaluating optical radiation have existed for decades and lamp safety standards refer to these TLVs®. These guidelines have been developed to avoid retinal injuries from exposure to very intense light sources (e.g., welding arcs). In most workplace settings, there is little chance that workers will be exposed to general lighting sources (GLS) used for visual purposes that exceed current TLVs®.
After viewing this webinar, you will:
- Be more aware of the significant changes now taking place in lamp technology and lighting installations—particularly those related to solid-state lighting.
- Learn the new discoveries since 2001 on the influence of the spectral distribution of environmental light on the circadian, neuroendocrine and neurobehavioral effects of light.
- Understand the role of newly discovered retinal photoreceptor (the intrinsically photosensitive retinal ganglion cell or ipRGC) that influences the circadian, neuroendocrine and neurobehavioral effects of light.
- Appreciate the differences between the current ACGIH® TLV® that protects against retinal injury from intense light sources and the use of the term “blue-light hazard.”
- Learn about the potential impact of lighting on the body’s circadian regulation and how this might affect shift work.
- Understand the causes of workplace complaints about new solid-state (LED) lighting installations.
This webinar is 1.5 hours in length and may be eligible for certification maintenance points.
