Monitoring Sulfur Dioxide in the Workplace through SO2 Analyzer

Sulfur dioxide or SO2 is a pollutant released by industrial processes and their presence in the environment is a serious concern because of its negative impact to global warming. The combustion of coal and petroleum generates sulfur dioxides into the atmosphere. Oxidation of sulfur dioxide usually when there are catalysts like NO2 forms H2SO4 and thus acid rain. Acid Rain Programs are trying to improve air quality by reducing SO2 emissions from power plants by 10 million tons or more than 60%. In order to implement the program which is currently on its full implementation, so2 analyzers are required to effectively and accurately measure sulfur dioxide. Industries found to have exceeded their emission allowances were assessed with penalties for a wider range of health and environmental improvements.

SO2 Analyzer for monitoring in workplaces

Sulfur dioxide is a gas typically found in workplaces but more significantly in industries that burn fossil fuels like power plants and petroleum refining companies. SO2 analyzers are used by both governments and corporations to ensure the health and safety of the workplace. The so2 analyzer is used in checking the composition of air so as to make effective plans and monitoring schemes for the workplace. Not only will the purchase of the so2 analyzer comply with government regulations and Acid Rain Programs but it reduces the health threat on the workers and people living near the vicinity of the plant. Even a minute of exposure to sulfur dioxide can result into health problems like asthmatic conditions and cardiovascular diseases.

Factors to consider when choosing so2 analyzer

SO2 monitoring may be handled through remote sensing wherein the ultraviolet bands are used in reading measurements from the so2 monitors. Recent instruments are in line with technological developments that measurements of SO2 can be generated from instruments like sorbent tubes, infringers, surface acoustic wave and sulfur dioxide fluorescent detectors. To be able to choose the best so2 analyzer, it is important to consider the origin and degrees of contamination in the workplace including actual time reaction in case a high degree of sulfur dioxide is detected. It is also important to consider the workplace in conjunction with the monitoring sites quality assurance project plan. Whatever data is collected through the so2 analyzer must be subject to regulatory review to ensure the reliability of the equipment and that quality objectives are achieved.

Installation of the so2 analyzer

It is also significant that any agency or company tasked with installation of the so2 analyzer, operation and reporting of data should develop standard operating procedures specific to the type of equipment used including make and model. Usually those responsible with installation should also see to the calibration of the system and data acquisition. The relevant technical and operations manual must be strictly followed in the setup and connection of the so2 analyzer, data acquisition system, calibration system and whatever telemetry necessary for the equipment to operate completely. Manufacturer’s operation and technical manuals should always be considered for specific instructions on how to hook up cables, instruments and other remote access hardware/ software that will be used in the workplace. 


I own a petrolium company so an so2 analyzer is a MUST!!! These gases can be harmful in the wrong amounts...
