Small handheld devices that require special care when handling are known as?

Small handheld devices that require special care when handling are indeed known as signal ejectors. These devices are designed to emit visual or audible signals and are often utilized in emergency situations to attract attention or convey information. Because they can contain pyrotechnic materials or other sensitive components that are used to generate a signal, proper handling is essential to prevent accidental ignition or misuse.

Signal ejectors must be treated with caution to ensure user safety and to maintain the device's functionality. The design typically includes safety features, but operators must still follow specific protocols for storage and handling to mitigate any risks associated with their use. Understanding the nature of these devices is crucial for safety and effective operation in critical situations.

In contrast, flare launchers, smoke generators, and explosive flares do have similar functionalities in signaling or providing visual indicators, but they may differ in their operational complexity, required handling protocols, or intended applications compared to signal ejectors. Each of these options encompasses different methods of signaling or generating visibility, but the specific focus on careful handling aligns most closely with the characteristics associated with signal ejectors.
