What is the Immediately Dangerous to Life or Health (IDHL) level for chlorine gas?

The Immediately Dangerous to Life or Health (IDHL) level for chlorine gas is established to indicate the concentration of chlorine that poses an immediate threat to health. This value is significant for ensuring the safety of workers who may be exposed to chlorine in various scenarios, such as in water treatment facilities where chlorine is commonly used for disinfection.

The correct IDHL level for chlorine is set at 10 parts per million (ppm). At this concentration, exposure can result in serious health effects, including respiratory distress, chemical burns, and in extreme cases, death. Knowing this value is critical for water operators and other professionals who work with hazardous materials, enabling them to implement necessary safety measures, such as personal protective equipment and appropriate emergency response plans, to safeguard themselves and others in the workplace.

Other options indicate levels that may not accurately reflect the immediate danger posed by chlorine gas, potentially leading to insufficient precautionary measures being taken by individuals working in environments where the gas is present. Understanding and adhering to the IDHL value is crucial in preventing accidents and ensuring a safer working environment.
