After breaking the seal, how is the signal activated?

The activation of the signal after breaking the seal is accomplished by pulling a cord. This method is commonly used in emergency signaling devices, such as inflatable life rafts and other safety equipment, to ensure a reliable and quick response when signaling for help or alerting others to a distress situation.

Pulling a cord provides a manual means to activate the signal, which can be critical in situations where operators may not have the ability or necessary dexterity to use more complex mechanisms. It is designed to be intuitive and requires minimal training, making it an effective choice for emergency scenarios where time is of the essence.

In contrast, other potential activation methods, such as pressing a button or turning a knob, may not provide the immediate response needed in emergencies or may require more precision than what the situation can afford. The design simplicity of pulling a cord aligns with the need for quick and straightforward operation in crisis situations.
