What is the first action required when the SO2 alarm sounds?

When the SO2 alarm sounds, the first action required is to evacuate the immediate area. This is critical because sulfur dioxide (SO2) is a toxic gas that can pose serious health risks. Evacuating the area ensures the safety of all personnel and minimizes exposure to the gas. It is a vital step to protect individuals from the harmful effects of inhaling SO2, which can cause respiratory issues and other health problems.

Following the evacuation, further actions such as notifying the safety officer, inspecting for gas leaks, or following HAZMAT procedures may be necessary. However, ensuring that people are moved to safety takes precedence to prevent any potential harm from exposure. Prioritizing evacuation during an alarm situation is a fundamental safety protocol in hazardous material response plans.
