In support of the Clean Air Act, the Visible Emissions Training is conducted by environmental centers and departments. This is to measure the quality of the air in the surroundings as shown by the lower percentage of emission opacity. There are certain limits that each area provide for automobiles and factories to meet before operations.
Unaided by any form of instruments, one can directly see through the naked eye the visible gasses and emissions in the air. These are comprised of black and white smoke, flown ashes, dusts and fumes. They are measured in micrometers not greater than two hundred in their diameter. They are also referred to as plumes. They can cause illnesses to living organisms particularly those that are manifested in respiration.
The development of Ringelmann chart in the late eighteen hundreds paved the way for visible emissions to be measured according to their density and opaque degree. The darker the plume and the denser it is, the more it can block light and reduce visibility which may be dangerous in the field of transportation. Opacity is measured in percentage. The greater it is, the more the view behind the plume will be obscured.
The EPA Reference Method has governed testing centers in requiring an accepted measure of opacity. It has guided observers in the pious determination of plume readings. An evaluative tool will prove the readiness of the trainee to employ the strategies taught in the seminar.
The trainee must stand at a distance that provides a clear view of the emissions. They can be a number of white and black plumes from a specific generator. The observing person should record his observations from a position perpendicular to the smoke direction. The line of sight should not include more than one plume at a time when multiple stacks are involved. The recommended distance in observing is about one quarter mile from the stack.
The information that the observer should be aware of are the type, location and source of plume. It will also be necessary to jot down the external factors affecting the test such as gust direction and the condition of the weather. Information pertaining the name and affiliation of the observer are needed as well. These help in the administration of proper recommendation to the people concerned.
A desired number of thirty readings should be done at a fifteen second interval. A more accurate reading can be garnered if it is done against a clear and contrasting background. The measurements should be rounded to the nearest five point interval measured in percent.
The garnered information may be tainted with doubt if miscalculation and biased factors are proven. Repetition of the entire procedure will be suggested. There are strategies in calculating that may make the data erroneous to some areas. A clear comparison should be provided by the observer to the clients. A reading of twentieth fraction of a hundred and less than are the allowable values of emission.
Anyone can take part in a Visible Emissions Training. The result is the determinant whether the observer can administer testings that will measure the compliance and enforcement of clean air regulations of a certain facility or vehicle. This seminar is one of the many ways one can help keep the environment safe.
