Sulfur Dioxide (SO2)

Sulfur Dioxide (SO2) is a pungent, colorless gas that poses serious health and safety hazards in facilities handling waste processing. Prolonged exposure to SO2 can result in respiratory irritation, eye discomfort, and complications for individuals with pre-existing conditions like asthma. OSHA sets a permissible exposure limit (PEL) of 5 ppm over an 8-hour workday, while NIOSH recommends a more stringent ceiling limit of 2 ppm to minimize health risks. This gas is frequently produced during the incineration of sulfur-containing materials. Given its potential dangers, continuous monitoring is required to maintain safe working conditions and ensure regulatory compliance.

Operations such as waste-to-energy plants or industrial material processing often release SO2 as a byproduct when burning sulfur-laden substances. These emissions not only create a hazardous environment for workers but can also lead to environmental pollution. SO2 is corrosive, particularly when it combines with moisture to form sulfuric acid, which accelerates the corrosion of equipment and infrastructure. This results in higher maintenance costs and potential system downtime, further underscoring the importance of monitoring systems.

Effective control of SO2 emissions involves utilizing advanced technologies like scrubbers and flue gas desulfurization systems, which reduce the gas before it is released into the atmosphere. Additionally, placing SO2 sensors in critical areas such as incineration chambers, ventilation outlets, and storage zones allows for real-time monitoring, ensuring rapid response to any buildup. These practices are crucial in protecting both personnel and infrastructure while keeping operations in line with safety regulations.
