What safety measure should be taken before reconfiguring BCC sensor arrays or weapon controls?

• A. Proceed with changes without notification if urgent.
• B. Follow lockout-tagout or safe-system procedures, confirm authority, and ensure personnel are clear.
• C. Only notify supervisor after changes complete.
• D. Ignore safety procedures if there is time pressure.

Answer: (B)

Before reconfiguring BCC sensor arrays or weapon controls, you must establish control over hazardous energy and follow authorized procedures. Lockout-tagout or safe-system procedures are designed to isolate the equipment from all energy sources and prevent any re-energization while work is being done. Applying locks or tags communicates that the system is under maintenance, and verifying de-energization ensures there’s no unexpected movement or activation. Confirming authority guarantees that only qualified personnel make changes, and ensuring personnel are clear of the area protects everyone from exposure to hazard or inadvertent operation of controls. This combination provides the necessary protection against accidental activation, stored-energy release, or misconfiguration during the reconfiguration process.

Other options fail because they bypass essential safety controls or rely on urgency as a justification. Notifying after the changes or proceeding without proper authorization and area clearance leaves the system vulnerable to unexpected energization or dangerous operations, which is not acceptable. Ignoring safety procedures under time pressure undermines protection and increases risk.
