Carbon monoxide cannot be seen or smelled. A CO alarm or suspected exposure requires fresh air and emergency help even when there is no visible smoke or obvious equipment fault.
An occupied stalled elevator needs prompt specialist assistance and clear communication. Building staff can coordinate help without attempting a rescue from the hoistway.
An alarm is not a troubleshooting invitation for untrained staff. Respond according to the building emergency plan even if prior activations proved unwanted.
Alarm, supervisory and trouble describe different system conditions. The exact display and the installed system instructions determine the response; a beep alone cannot diagnose the fault.
Treat unexpected fire-sprinkler discharge as a possible fire emergency. Your first task is helping people reach safety and giving responders accurate information.
Resetting a panel or replacing a wet tile does not close a fire-system incident. Keep restoration, occupancy authorization and building-damage repairs as separate work items.
An unexplained gas-like odor needs emergency action, not a maintenance experiment. Do not decide that it is just a floor drain or try to prove the source before leaving.
AED maintenance is mostly about readiness: the device is where it belongs, accessible, showing a normal ready status, and stocked with unexpired model-approved pads and battery.
A portable extinguisher is life-safety equipment. The maintenance technician's job is to make sure it is present, accessible, apparently charged and ready for use — and to hand service work to qualified fire-protection personnel.
