Description
The SafeAir chlorine badge is a monitoring system designed to indicate the presence of chlorine at concentrations below the permissible exposure limit. The SafeAir badge detects the presence of chlorine by forming a color change in the shape of an exclamation mark inside the triangle. This indication is produced by a color-forming reaction that occurs when chlorine reacts with a flat indicator layer.
Chlorine is a greenish-yellow gas with a pungent, irritating odor. Generally, chlorine is a potent respiratory system irritant. Mild exposures to chlorine cause burning of eyes, nose and mouth. Exposure to high concentrations (e.g. 1,000 ppm) is likely to be fatal. The OSHA PEL (permissible exposure limit) for chlorine is 1 ppm (ceiling), whereas the NIOSH REL (recommended exposure limit) is 0.5ppm (TWA). Chlorine is an important chemical commodity widely used in the production of safe drinking water. It is used extensively in the production of paper products, dyestuffs, textiles, petroleum products, chlorinated solvents, etc.
