Which practice helps prevent accidental mixing of oxidizers and fuels?

• A. Store oxidizers and fuels together for efficiency.
• B. Labeling eliminates the need to segregate.
• C. Keep oxidizers and fuels segregated.
• D. Store oxidizers above fuels.

Answer: (C)

Preventing accidental mixing of oxidizers and fuels relies on physical separation in storage. Oxidizers can dramatically accelerate combustion, so if they come into contact with fuels, a small spill or leak can lead to a rapid, uncontrollable fire or explosion. Keeping oxidizers and fuels segregated means storing them in separate areas or cabinets with barriers and sufficient distance, and ensuring incompatible materials don’t share the same space. This direct separation minimizes the chance that a spill, leak, or misplaced container could cause ignition or a violent reaction.

Storing them together for efficiency increases the risk of contact. Labeling helps, but it doesn’t prevent physical mixing or spills. Storing oxidizers above fuels is unsafe because leaks or spills can travel downward, bringing oxidizers into contact with fuels.
