What is the primary purpose of combustible gas indicators (CGIs)?

The primary purpose of combustible gas indicators (CGIs) is to determine the flammability of vapors. CGIs are specialized instruments designed to detect the presence of combustible gases and vapors in the environment. By monitoring the concentration of these gases, CGIs help assess the risks of explosion or fire, ensuring safety during hazardous materials operations.

This function is crucial in various settings, particularly during emergency responses to chemical spills or leaks, where identifying flammable conditions quickly can prevent hazardous incidents. While temperature measurement, gauging environmental conditions, and assessing structural integrity are important aspects in handling hazardous situations, they do not fall within the specific capabilities of CGIs. Thus, the focus on flammability detection highlights the critical role these devices play in ensuring safe practices in potentially dangerous environments.
