Visible Emissions Training is an effective strategy in informing the public about procedures in air pollution control. This ensures that there will be a reliable opacity observation in varied locations. The hazardous effect of air pollution prodded the environmental engineers to act and develop ways in controlling these problems.
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.
Under the EPA Reference Method Nine, the government adopted a standard inspection method to establish uniformity in the readings of measurements. This is the basis for training of the observers. There are various requirements that an observer should exhibit to pass the evaluation done after the training.
It is necessary that the trainee understands where he must keep his distance and up to what point should he conduct his observation. It is ideal that he will make observations at a distance perpendicular to the plumes and out of the direction of the wind. This will keep him from taking the plume in while conducting the reading.
Among the data that should be noted are the names of sources of the plume, location, type of the emission and the affiliation and name of the recorder. Distance of the observer, the date and time the plume is observed and the weather condition are of equal importance. These are all vital in the granting of the certificate and giving of recommendations during evaluation.
Opacity observations must be made at the point of greatest opacity at fifteen second intervals. A clear background of contrasting color will result to the highest reading accuracy. Readings must be recorded to the nearest five percent every fifteen second interval. There are states that require a minimum of thirty readings that covers a duration of approximately eight minutes.
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.
