What is the recommended water consumption for a firefighter engaged in strenuous activity over 1 hour?

The recommended water consumption for a firefighter engaged in strenuous activity lasting over 1 hour is 1 liter. This amount aligns with guidelines suggesting that individuals performing high-intensity work in hot environments need to hydrate adequately to maintain physical performance and prevent dehydration.

When engaging in strenuous activity, firefighters can lose a significant amount of fluid through sweat, and ensuring proper hydration is crucial for sustaining energy levels and cognitive function. Drinking 1 liter of water during such activities helps replenish lost fluids and supports overall bodily functions.

While options that suggest either lower or higher amounts may have their own scenarios, the standard recommendation during sustained physical exertion typically emphasizes around 1 liter to strike a balance between adequate hydration and realistic consumption rates during incidents.
