Which fire bottle has two squibs?

The correct answer indicates that Bottle 1 is specifically designed with two squibs. Squibs are pyrotechnic devices used to initiate the release of the extinguishing agent in a fire suppression system. Having two squibs allows for redundancy and can increase the reliability of the fire suppression system, ensuring that if one squib fails to activate, the second can still perform the crucial function of discharging the agent to extinguish a fire.

In this case, Bottle 1 having two squibs enhances its effectiveness and safety in emergency situations, providing peace of mind that the bottle is more likely to operate successfully when needed. Understanding this function is critical for those involved in fire safety and response, as it highlights the importance of the design and engineering of fire suppression systems.

Other choices may represent either a situation where a bottle has fewer squibs, is undesignated, or indicates a lack of squibs altogether, which would not provide the same level of reliability as Bottle 1. This distinction is essential in fire safety protocols and systems, emphasizing the importance of properly equipped fire suppression tools.
