What is the purpose of a flashlight in HAZMAT response?

The purpose of a flashlight in HAZMAT response is to provide a portable light source used for visibility. In hazardous materials incidents, conditions can often be challenging, including low light situations or areas with obscured visibility due to smoke, dust, or other environmental factors. Having a reliable light source enables responders to safely navigate the area, locate hazards, assess the situation, and carry out necessary actions without the limitations imposed by poor lighting.

While signaling for help and illuminating danger areas might appear relevant, they are generally secondary functions compared to the essential role of ensuring visibility. The flashlight aids primarily in helping personnel see what they need to address during a HAZMAT incident safely and effectively. Checking equipment configurations is also an important task, but it is not the primary function of a flashlight in this context.
