Benefits of Human Centric Lighting (HCL) in Control Rooms

Shift workers at chemical and petrochemical sites can gain important benefits related to HSE by using Glamox HCL solutions

The design and layout of control rooms is a scientific research field in its own right. Here, operators often work night shifts watching the operative state of plant equipment. A careful balance between activating light to increase alertness and non-activating light to help adjusting daily rhythms is needed as well as sufficient light levels to read documents and understand operating panels efficiently.

Challenges of shift work:
• Shift work has a negative impact on the health
• People working shifts have a high risk of accidents during the night shift, especially during the last hours of the shift.

Possible solution:
Human Centric Lighting solutions contain tuneable white luminaires and advanced light management systems that adjust the color temperature and light intensity according to the users’ physiological and psychological needs. The effects are adjusted daily rhythms and increased alertness.

These solutions require careful control of the light source’s color spectrum, intensity, exposure time and duration. Glamox provides a complete solutions to this.

By influencing the secretion of the “sleep hormone” melatonin using artificial lighting, we can adjust humans’ “body clock” in areas with little access to daylight.

• Exposure to more intense light may boost employees’ feelings of alertness and vitality during daytime and at night.
• Circadian light exposure during the daytime may have a positive effect on shift workers’ sleep during the subsequent night.
• Circadian rhythm adjustment for nightshift workers is possible.
• The light settings can influence employees’ appraisals of the lighting and the working environment.
• Their preferred light settings differ substantially from person to person. Thus individual lighting control will affect job satisfaction positively
