A heat alert was issued for Tulsa Monday afternoon.
EMSA issued the alert at 5:15 p.m. after responding to six suspected heat-related calls, they said in a news release.
Four of the patients were transported to local hospitals in "non-emergent" condition.
Patients ranged in age from 40 to 58 years old.
EMSA is urging citizens to make a plan to stay safe.
Plan the amount of time you think will be outdoors and take appropriate amounts of water or other fluids with you, even if just planning for a short amount of outdoor time, EMSA said.
Emergencies can happen and you could be stranded outdoors longer than expected.
Always have a cell with you to call 911, if needed.
Plan your schedule to allow for frequent breaks indoors, if possible.
