Notes
Caution :
Fatigue is possible with prolonged exposure
and activity. Continuing activity could result in
heat cramps
Extreme caution :
Heat cramps, and heat exhaustion are possible.
Continuing activity could result in heat stroke
Danger :
Heat cramps, and heat exhaustion are likely ;
heat stroke is probable with continued activity
