Illumination Survey or Light Assessment or Lux Level survey is conducted to identify Too much bright light, glare, low light or flickering light to avoid potential hazards and evaluation of risk to improve employee safety.
Sufficient Lighting has major impact on performance and efficiency of the employees at workplace. It helps them to read labels and safety instructions clearly without any hurdles, to make sure prevention of health hazards of employees.
Therefore there should be appropriate light fall on desk or work area of the employees. Too much bright light (High intensity), Strong glare, Low light, or continuous flickering light are unsuitable for workplace. To ensure good lighting the persons who is accountable for workplace should contact environmental consultants to conduct Illumination Survey or else you can do it on your own by using a lux meter.
Purpose of Illumination Survey In short purpose to lighting assessment is study of lighting condition in work environment.
Illuminance is common parameter while studying Illumination measurement. It defines or measures the amount of light is falling on unit surface area of workplace and its Unit is lux (lx). It is used to evaluate the capability of lighting for seeing an object.Also Read what is Workplace Monitoring procedure?
Illuminance is measured by Lux Meter which is small instrument containing sensor and Display parts. Sensor part is placed on a place where Illuminance to be measured and display part shows reading in Lux unit.
In general, uniform light is required in workplace to perform particular type of activity. Eg.Office, reception etc. To measure Illuminance environmental consultants can help.
To measure Illuminance big area should be divided into small equal parts and which can be in square shape. Then sensor of luxmeter or Monitor lighting kit is kept at the centre of each square. By observing results we can come to know about distribution of light in workplace. Also Average of all these values obtained by this method gives average value of illuminance.
In some workplaces some task may demand more intensity or brightness than normal. In these type of conditions a local light is installed in area of that task or near that workstation.
To measure Illuminance for a particular task majorly 4 Points are selected on work plane. Their Illuminance is measured for each point in illumination monitoring procedure. Average Illuminance of that task place is calculated by taking average for those 4 values
Appropriate level of illumination is the intensity of light which allows you to see what you need to see without any visual discomfort. Illumination is measured in Lux unit.
In every factory where natural sun light is not reachable or not uniform then in that case additional uniform lighting should be provided. It should avoid hard shadows, strong contrast, free from direct or reflected glare. Role of adequate lighting at workplace plays vital role in employee safety.
Requirement of lighting differs based of type of work & Place. Hence there are two types of lighting requirement based on place and type of work is being carried out.
Recommended Lighting Levels by Maharashtra Factory Rules 1963.
Lighting Standards for Places:
Illumination Survey or Lighting Assessment is very important factor to find out health hazards, it can give idea what are blind spots in workplace, how to overcome them, where to put light sources to get best out of them etc. If this process followed correctly then it will help to increase efficiency and performance of Employees.
We suggest you to that above mentioned concepts are very basic in nature for illumination measurement. An illumination measurement professional may or may not follow these instructions as per his personal judgement or experience.
