What is the minimum distance to segregate incompatible materials in storage?

The correct answer, which specifies a minimum distance of 20 feet to segregate incompatible materials in storage, is based on safety regulations established to prevent hazardous reactions. Incompatible materials can react in dangerous ways if they are stored too close to one another, potentially leading to fires, explosions, or toxic releases.

The 20-foot separation distance serves as a safety buffer that helps to reduce the likelihood of such incidents occurring. This regulation is particularly crucial in environments where various chemicals or fuels are stored, as certain substances can ignite or react violently in the presence of others. By adhering to this minimum distance, facilities can better manage risks associated with chemical storage, thereby protecting both personnel and property.

While the other distances may seem plausible, they do not meet the standardized requirements that have been established to ensure safe storage practices in facilities handling fuel oils and other potentially reactive materials.
