• To design circadian healthy light engines, fixtures and bulbs
• To specify lighting for customers that is safe and healthy, and not harmful
• To optimize color and performance of circadian safe light

√ Polychromatic White Light (CIE 1931 White Color)
√ Freely Moving and Working Human Occupants
√ Typical workplace light intensities (200-1,000 lux)
√ Normal work shift light exposure duration (8-12 hours)
√ Typical CCT range (2700 – 5000 K)
√ Color Rendering Index >80
√ Measured Response relevant to health impact of light

their new 2018 standards
Dr Steve Lerman MD, MPH, FACOEM
formerly ExxonMobil Medicine and Occupational Health
Department
Chairman of API ANSI Committee on RP755 Fatigue Risk
Management Standards
© 2018 CIRCADIAN LightRP-755 Background
• Developed in response a CSB recommendation after BP TX City’s
2005 incident
• CSB concluded that worker fatigue likely played a role in the
incident
• Urged the API & USW to develop an ANSI standard to “to
develop fatigue prevention guidelines that would, at a minimum,
limit hours and days of work and address shift work”
• API convened a committee, following ANSI Guidelines
• Members included representatives from refining & chemical industries,
the USW and experts in the area of fatigue management
• RP-755; the first industry standard to utilize a comprehensive Fatigue
Risk Management System (FRMS) approach was issued in 2010
© 2018 CIRCADIAN LightLighting in RP-755
• Called for the use of bright light to enhance alertness, using indirect
lighting to minimize glare
• IARC had recently issued a monograph calling shiftwork a “probable
carcinogen” due to circadian disruption
• Balancing this recent statement against the known risks of fatigue and
the known alertness benefits of lighting, this recommendation was
retained
© 2018 CIRCADIAN LightLighting in RP-755
• Since then:
• The connection between circadian disruption has been strengthened
• Technology can now offer the fatigue-related benefits of bright light while
minimizing circadian disruption
• As a result, the second edition of RP-755, to be issued by YE 2018 will
include:
• “… light sources at night should be selected to minimize circadian system
disruption”
• RP-755 will be the first standard addressing the issue of circadian disruption
due to work at night

“Merely adjusting CCT, light intensity, or even SPD with time
of day does not qualify a lighting system as “circadian”
CCT color tuning products …should not be labelled “circadian”
unless they have been demonstrated through properly
designed clinical trials to be capable of optimizing the phase,
amplitude and/or entrainment of the circadian system to
promote human health and wellbeing.”

• Prevent circadian disruption and health consequences
• Removal of 440-490nm blue light at night
• Providing blue-rich 440-490nm light during day
• Sustain human alertness and performance
• Provide sufficient illumination levels for work
• Deliver white light with good color rendering

• Traditional lighting negatively impacts health, well-being and performance
• Too little blue-rich light during the day
• Too much blue-rich light at night
• The solution is here today
• Dynamic circadian lighting that provides high blue-content during the day and less
than 2% blue-content at night
• Adopted by over a dozen 24/7 operations and Fortune 500 companies
• Circadian lighting provides your workforce with:
• Improved performance: reduced fatigue, reduction in errors
• Improved health: Decreased obesity (BMI), reduced diabetes risk
• Avoid future liability risk of conventional lighting
