Good lighting for outdoor workplaces
Basically speaking, outdoor workplace lighting addresses the same task as interior lighting, ensuring visual task performance and health and safety at work.
However, the design requirements are different. During the day, our eyes provide around 80% of the sensory impressions we register. But at night, the visual acuity of the eye drops to just 3 - 30% of its day-time level – depending on lighting. What is more, the risk of glare is significantly higher than in bright conditions.
Spatial orientation and field of vision are considerably reduced in darkness and
physical performance drops to less than 10% as a result of fatigue due to disruption of natural sleep patterns. This is why most accidents caused by human error occur at night. Human biorhythms are subject to marked fluctuation.
Performance decreases sharply at night; hence the loss of concentration and the increase in the risk of accidents. Accidents at night are both more frequent and more serious than they are during the day.
