Question

whats most reliable indicator you should use when determining if you should modify activity for heat?

○ local weather report

○ wet bulb temperature taken at your field

○ heat index

○ humidity percentage

Explanation:

To determine the most reliable indicator for modifying activity in heat, we analyze each option:

• Local weather report: General and not site - specific.
• Wet bulb temperature at the field: Directly measures heat stress at the actual activity location, accounting for temperature, humidity, and wind, making it highly reliable for on - site heat - related activity decisions.
• Heat index: A general calculation, less site - specific than wet bulb temp at the field.
• Humidity percentage: Only one factor, not a comprehensive indicator.

Answer:

B. Wet bulb temperature taken at your field
