What is the horizontal distance that extends from the edges of containers holding Class I liquids in ventilated areas classified as?

The correct choice for the horizontal distance that extends from the edges of containers holding Class I liquids in ventilated areas is indeed 2 feet. This specification is based on the guidelines provided in safety regulations for hazardous materials and the inherent risks associated with the storage of flammable liquids.

Class I liquids are highly flammable, which necessitates measures to mitigate the risk of fire or explosion. The 2-foot distance serves as a safety buffer zone, ensuring that any potential vapors or accidental spills do not pose an immediate hazard to personnel or ignition sources in the vicinity. This distance is established to help contain any hazards that may arise from incidents involving these liquids and is informed by practices aimed at promoting safety in environments where flammable substances are present.

Understanding this requirement is crucial for compliance with safety regulations and for implementing effective safety protocols in handling hazardous materials.
