When using a fire extinguisher, the cylinder should be kept in which position?

The cylinder of a fire extinguisher should be kept in a vertical position to ensure proper functioning and safety. A vertical position allows the internal components, such as the propellant and extinguishing agent, to be properly distributed within the cylinder. Additionally, this orientation helps maintain the integrity and functionality of the nozzle and the other mechanisms needed to effectively discharge the extinguishing agent.

Keeping the extinguisher in a vertical position also facilitates easier access and handling during an emergency. In this position, the extinguisher is less likely to become damaged or have its components compromised, ensuring that it will operate correctly when needed.

In contrast, if the extinguisher were kept horizontal, upside down, or overhead, it could create issues with the pressurization system and distribution of the agent, potentially rendering it ineffective during a fire emergency.
