How should primers be stored relative to other components?

• A. With propellants to simplify handling.
• B. In segregated, secure areas away from propellants and other energetic materials to minimize accidental initiation.
• C. In the same container as other components.
• D. In outdoor storage.

Answer: (B)

Primers are highly sensitive energetic components that can be initiated by heat, friction, impact, or static electricity. To minimize the risk of an accidental initiation spreading from one item to others, they must be kept in segregated, secure areas away from propellants and other energetic materials. This separation reduces the chance of a chain-reaction incident and helps control access to prevent mishandling. Storing primers with propellants or in the same container increases the risk of inadvertent initiation, and outdoor storage exposes them to temperature and moisture extremes that can degrade safety and handling. So the best practice is to keep primers in a dedicated, secure, segregated area away from propellants and other energetic materials.
