Chlorine is one of the 90 elements essential to daily life, along with oxygen, hydrogen, and carbon. Chlorine is used in many industrial processes, including manufacture of electronics, water purification, production of numerous synthetic materials, and medicines. Around 12 million tons of chlorine are produced per year for such purposes in North America alone. The Occupational Safety and Health Administration (OSHA) recognizes chlorine as a hazardous material and imposes strict exposure limits in the workplace. This course presents an overview of chlorine, its health risks, how to control and respond to chlorine exposure, and how to protect your workforce from potential harm.
