What should you never do until the fire condition is verified by the FDNY personnel?

The action that should never be taken until the fire condition is verified by FDNY personnel is to reset the fire alarm system. Resetting the fire alarm system during a potentially active fire situation can lead to serious safety risks. If the alarm is reset, occupants may be unaware of an ongoing fire, and critical alerts to emergency services could be compromised.

Verification of the fire condition by authorized personnel ensures that any threat is adequately assessed before any system reset occurs. This helps to maintain the integrity of the emergency response and guarantees that people in the vicinity are informed of the danger. It's essential to allow trained firefighters to evaluate the situation before making any changes to the system that could diminish its effectiveness in alerting individuals of a fire emergency.

Engaging in other actions, such as activating alarms, performing routine maintenance, or silencing alarms, also carries specific implications and consequences, but resetting the system is particularly critical to avoid, as it may completely disable the alarm and lead to higher risks during a fire situation.
