Description
The Sulfur Dioxide Colorimetric SafeAir Badge is a monitoring system designed to indicate the presence of sulfur dioxide at concentrations below the permissible exposure limit. The SafeAir sulfur dioxide badge detects the presence of sulfur dioxide by forming a color change in the shape of an exclamation mark inside the triangle. This indication is produced by a color-forming reaction, which occurs when sulfur dioxide reacts with a flat indicator layer.
Operating Instructions Sulfur Dioxide Monitor (Part Number: 382014) Introduction Sulfur dioxide is a colorless gas with a characteristic, irritating, pungent odor. It is corrosive and irritating to the upper and lower respiratory tracts, skin and eyes. Symptoms of mild exposure to sulfur dioxide include coughing, wheezing, shortness of breath, headache and vomiting. Exposure to high concentrations of sulfur dioxide is extremely destructive to the respiratory tract tissues. Exposure of the eyes to high concentrations may result in ulceration of the conjunctiva and cornea, whereas contact with skin causes severe burns. OSHA PEL (permissible exposure limit) for sulfur dioxide is 5 ppm (TWA). NIOSH REL (recommended exposure limit) for sulfur dioxide is 2 ppm (TWA).
Sulfur dioxide is a widely spread air pollutant. It is emitted as a byproduct in burning coal fuels in electric power generating plants, industrial boilers and molten sulfide ores in metallurgical plants. Sulfur dioxide is also used in the production and treatment of metals, sugar, cellulose, leather, fertilizers, ceramic, batteries, paper and many others.
