Where two or more dry chemical systems are used to protect a common hazard, they shall be arranged for ______ operation.

Explanation:
When two or more dry chemical systems protect the same hazard, they must be arranged to discharge at the same time. The reason is to deliver the full required amount of extinguishing agent immediately, ensuring complete, uniform coverage of the hazard. If the systems activated in sequence or independently, there could be a delay or uneven discharge, allowing the fire to grow or creating gaps in protection. Coordinating them for simultaneous operation provides redundancy and maximizes the effectiveness of the protection by having both systems contribute together the moment a threat is detected.
