Which statement is true about hourly water loss during strenuous work in hot PPE?

• A. 2 quarts per hour
• B. 1 quart per hour
• C. 4 quarts per hour
• D. 6 quarts per hour

Answer: (A)

When you work hard in hot PPE, your body sweats heavily to cool itself, and the gear makes evaporative cooling less efficient, so sweat losses rise to a high, sustainable level. About two quarts of water per hour is a typical estimate for sustained, strenuous work in hot protective clothing, and it aligns with safety guidance on matching fluid replacement to losses to prevent dehydration and heat stress during live-fire activities. A rate of one quart per hour underestimates what happens with intense effort in heat, while four or six quarts per hour would imply unrealistically high losses that are unlikely to be sustained and could lead to other issues. So, two quarts per hour best represents hourly water loss in these conditions.
