- reducing glare off metallic or liquids, as well as screens, as this leads to performance impediments. This can be done by equipping workers with glare resistant safety glasses.
- using the best quality lighting products that are unlikely to flicker.
- using the same lighting source at the same level of strength at all stages and areas in the business.
- maintaining a positive light strength that both promotes mood-enhancement as well as safety-enhancement benefits.
As economies boom, and production and GDP levels rise, it is only natural that there is a drastic increase in the amount of construction that occurs worldwide. Developing and strengthening a country's infrastructure is often the first goal for states that are having a positive level of economic growth. South Africa is no different in this respect. There are constantly new projects, investors and private companies that add to the ever expanding grid of houses, office parks, shopping centres, public buildings, factories, storage facilities and mines. And when there is a rise in the measure of construction projects, there comes an increase in construction related dangers.As the time and space required for the constructs diminishes, more and more construction workers are expected to work during the night. The inability to see properly presents one of the greatest probabilities of working accidents in the construction sector.Age FactorIt's no secret that most professionals in the construction industry are largely defined by their levels of experience. It is for this reason that the older generation of professionals are a necessity in the business, whether by transferring their knowledge on to younger professionals, by being the most skilled in a particular trade, or by recognizing problems or room for improvement. It is also no mystery that the visual performance of professionals diminishes when they age. In just 30 years, between the ages of 30 and 60, the light requirement to read text on a page increases from 3 lux (that of a overcast twilight) to 20 lux (that of typical living room lighting).Light and MoodThe level of lighting in and around the modern construction site, mine or factory has an influence on the mood and alertness of the working individual. Light levels above 1000 lux (overcast midday/studio lighting) help ensure full alertness from the working individuals, whereas light levels between 400 - 1000 lux (sunset/sunrise and overcast day) are said to exhibit positive mood levels in individuals, making them more willing to perform tasks. Light of a poorer quality is also prone to causing headaches, eye-strain and ultimately fatigue.Work AccidentsStudies have revealed that high levels of good-quality lighting in the construction and mining sectors have led to fewer accidents in the workplace. This sounds like an obvious fact, but considering that some floodlights produce less than 1000 lux from a distance, most lighting solutions in the construction sectors are not sufficient enough to reduce accidents. A German study in 1995 proved that the number of accidents in the metal industry reduced by 50% after lighting was changed from 500 lux to 1500-2000 lux. The number of rejects in the industry also dropped dramatically.It is absolutely essential that there is adequate lighting in construction, manufacturing and mining sectors. The presence of good quality lighting increases the performance of workers, while a strong light source leads to fewer accidents and fewer defects in production. Some tips on lighting in the construction/mining/manufacturing industries include:
