If a container of ethylene oxide has been subjected to fire for a prolonged period of time, what is the recommended distance for safe evacuation?

1. 1,000 feet

2. 2,500 feet

3. 5,000 feet

4. 10,000 feet

The correct answer is: 5,000 feet

When dealing with hazardous materials like ethylene oxide, safety protocols are crucial, especially in the case of prolonged exposure to fire. Ethylene oxide is a flammable and toxic gas that can pose serious health risks and has a low flash point, meaning it can ignite easily. For this substance, the recommended evacuation distance of 5,000 feet is based on the potential for explosion and the toxic effects of the gas. Evacuating individuals from this distance helps to ensure that they are sufficiently far away from any potential fireball, explosion, or harmful vapor release that could occur if the container ruptures. In emergency management, it’s essential to prioritize the safety of both emergency personnel and the public, so the larger evacuation zone gives responders adequate time and space to control the situation while protecting nearby individuals from significant harm. Thus, this distance is established based on industry standards and safety guidelines concerning the handling of narcotics and hazardous materials during a fire.
