Which two factors determine stay times for PHEL Curves 1-3?

Explanation:
Stay times for PHEL Curves 1-3 are determined by how long you’re working and how hot the space is. The longer you stay on task, the more heat your body accumulates; the hotter the surroundings, the less heat you can safely shed. Together, these two factors set the safe duration shown on the curves. Other conditions like humidity, weather, altitude, or lighting can affect comfort or heat transfer in some scenarios, but they aren’t the primary inputs used to define these stay times.
