How should fire extinguishers be positioned in a vehicle?

When positioning fire extinguishers in a vehicle, it is crucial to ensure that they are secured to prevent movement while also being easily accessible in case of an emergency. Securing the fire extinguisher mitigates the risk of it shifting during transit, which could potentially render it inaccessible or ineffective in an emergency situation.

Furthermore, having the extinguisher easily accessible means that operators or passengers can quickly grab it when needed, without having to fumble or search for it. This accessibility can significantly reduce response time in the event of a fire, which is critical for safety.

The other options, while they may suggest visibility or convenience in a different context, do not prioritize the essential balance of security and accessibility needed for effective fire safety in a vehicle.
