Texas Heat: A Deadly Workplace Hazard
Texas leads the nation in heat-related deaths, and agricultural workers face the highest risk of any occupation. The combination of strenuous physical labor, sun exposure, humidity, and often working alone creates deadly conditions during Texas summers. Heat stroke can kill in less than an hour if not treated. Knowing how to respond to heat emergencies isn't optional for Texas ranchers - it's essential survival knowledge.

Understanding Heat Illness Progression
Heat illness progresses through stages. Recognizing early signs and intervening immediately prevents progression to life-threatening heat stroke.
Heat Cramps (Mild)
- Painful muscle spasms, usually in legs, arms, or abdomen
- Heavy sweating
- Thirst
- Normal or slightly elevated body temperature
- Rest completely
- Drink electrolyte solution (sports drink, oral rehydration solution)
- Gently stretch affected muscles
- Do NOT return to work until cramps resolve
Heat Exhaustion (Moderate - Emergency)
- Heavy sweating (or sweating may have stopped)
- Cool, pale, clammy skin
- Weak, rapid pulse
- Nausea or vomiting
- Headache
- Dizziness or fainting
- Weakness, fatigue
- Muscle cramps
- Body temperature elevated but typically below 104 degrees F (40 degrees C)
- Remove or loosen clothing
- Apply cool water to skin
- Fan vigorously
- If alert, give cool water or electrolyte drinks
- Monitor closely for 30-60 minutes
- Seek medical attention if not improving within 30 minutes
Heat Stroke (Severe - LIFE THREATENING)
- High body temperature - 104 degrees F (40 degrees C) or higher (may be even higher)
- Altered mental status - confusion, slurred speech, irritability, combativeness, seizures, or unconsciousness
- Hot skin - may be dry OR still sweating
- Rapid, strong pulse
- Throbbing headache
- Nausea, vomiting, or diarrhea
- Rapid, shallow breathing
- Possible seizures
- Possible loss of consciousness
Heat Stroke Emergency Response Protocol
Step 1: Recognize Heat Stroke
- AND/OR temperature of 104 degrees F or higher
- AND/OR has stopped sweating with hot, flushed skin
- Exact location with GPS coordinates or directions
- Current condition (conscious/unconscious, breathing)
- Actions you're taking
- Immerse the body in cold water (50-59 degrees F ideal)
- Stock tanks, troughs, large coolers - any container works
- Keep head above water
- Continuously agitate the water for better cooling
- Monitor for shivering (reduce immersion if severe shivering)
- Spray or pour cool water over entire body continuously
- Fan vigorously (create air movement)
- Apply ice packs or cold wet towels to:
- Neck (sides and back)
- Armpits
- Groin
- Behind knees
- Rotate ice packs frequently
- Continue until body feels cooler to touch
- Stock tank water
- Ice from coolers
- Wet sheets or towels
- Vehicle air conditioning (place patient in cool vehicle)
- Create shade if none exists
Step 4: Position the Patient
- Position for cooling treatment
- Keep calm and reassured
- Continue cooling
- Monitor breathing closely
- Continue cooling simultaneously if possible
- AED if available
Step 5: Monitor and Document
- Breathing rate and quality
- Skin temperature and color
- Time cooling started
- Response to treatment
- OR patient becomes alert and oriented
- OR patient begins shivering severely (but do not let temperature rise again)
Step 6: Prepare for Transport
- Maintain mild cooling if temperature tries to rise
- Protect airway if unconscious
- Have someone guide emergency vehicles to location
Heat Emergency Response by Setting
In the Field/Pasture
- Vehicle air conditioning - put patient in cab with AC on max
- Water from any clean source - pour over body
- Remove outer clothing to maximize evaporation
- Fan with whatever is available (hat, cardboard, shirt)
- Call 911 before you become confused
- Get to shade/vehicle
- Remove clothing, pour water on yourself
- Text your location to someone if voice communication fails
At Ranch Buildings
- Use hose with cool water
- Create improvised immersion (water trough, large cooler, lined truck bed)
- Use ice from freezers/ice machines
- Multiple fans for air movement
- Cold wet towels from refrigerator/freezer
Remote Locations Without Water
- Remove all possible clothing
- If patient is sweating, don't wipe it off - fan to increase evaporation
- Dig into cooler soil if nothing else available
- Call for helicopter evacuation
What NOT to Do in Heat Emergencies
Never:
- Give anything by mouth to an unconscious person
- Force fluids if nauseated or vomiting
- Use ice water immersion if the person is shivering uncontrollably (mild cold water okay)
- Apply rubbing alcohol (can be absorbed through skin)
- Delay cooling to transport (cool first, transport second)
- Leave a heat stroke patient alone
- Assume improvement is permanent (rebound hyperthermia can occur)
Common Mistakes:
- Not cooling aggressively enough (timid sponging won't work)
- Stopping cooling too soon
- Not recognizing altered mental status as heat stroke
- Waiting too long to call 911
- Giving ice water to drink (causes stomach cramps and vomiting)
Heat Emergency Prevention Response
Monitoring Workers and Family
- Know the signs of heat illness
- Have authority to stop work and cool down
- GPS tracking for solo workers
- Scheduled text/call check-ins
Environmental Monitoring
|------------|-----------|----------------------| | 80-90°F | Caution | Drink water, watch for symptoms | | 91-103°F | Extreme Caution | Take frequent breaks in shade, extra water | | 103-125°F | Danger | Limit outdoor work, 15 min work/15 min rest | | >125°F | Extreme Danger | Only emergency work, constant monitoring |
Pre-positioning for Emergency Response
- Electrolyte drinks
- Shade structures or tarps
- Extra water for cooling (not just drinking)
- Communication devices
- First aid supplies
- Ice chest
- Emergency blanket (for shade)
- Fan (battery operated)
- Spray bottles
Special Populations
Increased Risk Groups
- Medications may impair heat response
- Chronic conditions increase risk
- Monitor more frequently
- Gradual increase in work intensity
- Extra monitoring and breaks
- Beta-blockers
- Antihistamines
- Antidepressants
- Stimulants
- Check with doctor about heat risk
- May have impaired heat regulation permanently
- Extra precautions needed
Youth Workers
- Children heat up faster than adults
- May not recognize or report symptoms
- Need more frequent breaks and monitoring
- Limit strenuous work in high heat
- Never leave in enclosed vehicles
After a Heat Emergency
Immediate Aftermath
- Organ damage may not be immediately apparent
- 24-48 hours of observation recommended
- No return to heat exposure for days or weeks
Return to Work Guidelines
- Can usually return same day after rest and rehydration
- Start with lighter work
- Minimum 24-48 hours rest
- Gradual return to heat exposure
- Watch for recurrence
- May take weeks to months to recover heat tolerance
- Permanent impairment possible
- Follow physician guidance strictly
Documentation
- Symptoms observed
- Treatment provided
- Outcome
- Follow-up needed
Emergency Supply Checklist for Heat Response

- [ ] Automated external defibrillator (AED)
- [ ] Vehicle with functioning AC
- [ ] Portable shade structures
Bottom Line
- Heat stroke kills fast - Brain damage begins within minutes at extreme temperatures
- Altered mental status = heat stroke - Any confusion in heat is an emergency
- COOL FIRST - Aggressive cooling is the #1 treatment priority
- Call 911 immediately - Don't wait to see if they improve
- Cold water immersion is best - Use stock tanks, troughs, any container
- If no immersion, wet and fan - Evaporative cooling can work
- Cool aggressively - Timid cooling doesn't save lives
- Don't stop too soon - Continue until temperature below 102 degrees F
- Prevention is best - Water, rest, shade, buddy system
- Monitor high-risk people - New workers, older workers, medication users
