Hot Weather Hazards in Metal Scrap Yard Operations

Overview

Hot weather hazards represent some of the most dangerous and potentially fatal conditions workers face in scrap metal yards. The combination of high ambient temperatures, radiant heat from metal surfaces, physical exertion, and heavy PPE creates an environment where heat-related illnesses can develop rapidly and progress to life-threatening emergencies within minutes. Every employee must understand these hazards, recognize the symptoms in themselves and others, and take immediate action when signs appear.

CRITICAL REQUIREMENT: Any signs or symptoms of heat-related illness must be reported to supervisors and management immediately. Early intervention saves lives—waiting can be fatal.

Why Scrap Yards Create Extreme Heat Hazards

The Perfect Storm of Heat Exposure

Metal scrap yards compound heat dangers in ways few other workplaces do:

• Metal Surfaces as Heat Radiators: Dark metal absorbs and radiates intense heat—surface temperatures can exceed 150°F even when air temperature is 90°F
• No Shade or Natural Cooling: Open yards offer minimal shade; metal piles and equipment block cooling breezes
• Required PPE: Hard hats, safety glasses, steel-toed boots, long pants, and high-visibility vests trap body heat and prevent natural cooling through evaporation
• High Physical Demands: Constant movement, lifting, climbing, and manual labor generate significant metabolic heat
• Reflected Heat: Light-colored surfaces and metal reflect additional heat onto workers from multiple angles
• Equipment Heat: Running machinery, vehicles, and cutting operations add radiant heat to the environment
• Duration of Exposure: Workers spend entire shifts (8-10+ hours) in these conditions with limited relief

The Compounding Risk Factor

Heat stress is cumulative. Your body’s ability to handle heat today depends on:

• Your hydration status from yesterday and the days before
• How well you recovered from previous heat exposure
• The total heat load accumulated over consecutive hot days
• Your overall health and fitness level
• Medications you take that may affect heat regulation

This is why drinking water only on hot days is dangerously insufficient—you must maintain hydration constantly.

The Four Stages of Heat-Related Illness

Heat illness exists on a spectrum from mild to fatal. Understanding each stage is critical because early intervention at mild stages prevents progression to medical emergencies.

---

1. HEAT RASH (Prickly Heat)

What It Is

The mildest form of heat illness caused when sweat ducts become blocked and inflamed, typically in areas where clothing restricts airflow or where skin surfaces touch.

Exact Symptoms

• Small red bumps or blisters on the skin, appearing in clusters
• Intense itching or prickling sensation that can be very uncomfortable
• Most commonly occurs in skin folds: neck, chest, groin, elbow creases, under breasts
• Areas covered by tight PPE or clothing are particularly susceptible
• Skin may feel rough or sandpaper-like to touch
• May develop a burning sensation

What Causes It

• Excessive sweating combined with blocked sweat glands
• Friction from clothing or PPE
• Prolonged heat exposure without allowing skin to breathe
• Working in humid conditions where sweat cannot evaporate

What to Do

Immediate Actions:

1. Report symptoms to your supervisor (even though mild, it indicates heat stress is beginning)
2. Move to a cooler, shaded area when possible
3. Remove or loosen tight clothing and PPE when safe to do so
4. Keep the affected area dry and cool
5. Avoid ointments or creams that can further block pores
6. Allow skin to air-dry between sweating episodes

Prevention:

• Wear moisture-wicking undergarments when possible
• Take breaks to remove PPE and allow skin to cool and dry
• Change sweat-soaked clothing during breaks
• Use powder in friction areas to reduce moisture buildup

Why This Matters: While not dangerous itself, heat rash signals your body is struggling with heat management and you’re at increased risk for more serious conditions.

2. HEAT CRAMPS

What They Are

Painful muscle spasms caused by loss of electrolytes (salt and minerals) through heavy sweating. Heat cramps are a warning sign that heat exhaustion may follow if not addressed.

Exact Symptoms

• Sudden, sharp, painful muscle spasms that can be intensely painful
• Most commonly affect: calves, thighs, abdominal muscles, arms, and shoulders
• Muscles become hard and tight during cramping episodes
• Cramps may last from seconds to several minutes
• Muscles may visibly twitch or knot under the skin
• Pain intensity can range from moderate to severe
• Often occur during or after intense physical exertion
• May occur several hours after work (evening or night cramps)
• Affected muscles are tender to touch even after cramping stops

What Causes Them

• Heavy sweating depletes sodium and other electrolytes
• Drinking only plain water without replacing electrolytes dilutes blood sodium further
• Intense physical exertion in hot conditions
• Inadequate salt intake in diet
• Dehydration reducing blood volume

What to Do

STOP WORK IMMEDIATELY:

1. Report to your supervisor right away – Heat cramps indicate significant electrolyte depletion
2. Move to a cool, shaded area and sit or lie down
3. Stop all physical activity – continuing work will worsen the condition
4. Drink electrolyte-replacement fluids:
   • Sports drinks (Gatorade, Powerade)
   • Electrolyte solutions
   • NOT just plain water alone
   • Drink 16-32 ounces over 15-30 minutes
5. Gently stretch and massage the cramping muscle
6. Do not return to heavy work for the remainder of the day
7. Monitor for progression to heat exhaustion symptoms

Medical Attention Needed If:

• Cramps last longer than one hour
• Cramps don’t improve with rest and fluids
• Person has heart problems or is on a low-sodium diet
• Symptoms of heat exhaustion develop

CRITICAL WARNING: Heat cramps are your body’s alarm system. They mean you’ve been losing fluids and electrolytes faster than you’ve been replacing them. If ignored, heat exhaustion or heat stroke can follow within hours.

---

3. HEAT EXHAUSTION

What It Is

A serious heat-related illness where the body can no longer cool itself effectively. Body temperature rises to 100-104°F. Heat exhaustion is a medical emergency that requires immediate intervention. Without treatment, it progresses to heat stroke, which is often fatal.

Exact Symptoms

Physical Symptoms:

• Heavy, profuse sweating – skin may be cool and moist despite high temperature
• Pale, ashen, or grayish skin color – loss of normal skin tone
• Weak, rapid pulse – heart rate over 100 beats per minute
• Rapid, shallow breathing – respiratory rate increased
• Body temperature 100-104°F – measured rectally for accuracy
• Extreme fatigue or weakness – difficulty standing or walking
• Muscle cramps throughout the body
• Dizziness or lightheadedness – feeling faint

Neurological Symptoms:

• Headache – often intense, throbbing
• Nausea and/or vomiting – may be severe
• Confusion or difficulty concentrating – unable to think clearly
• Irritability or mood changes – uncharacteristic behavior
• Coordination problems – clumsy movements, stumbling

Other Warning Signs:

• Thirst – intense, unquenchable
• Fainting or near-fainting – loss of consciousness briefly
• Dark-colored urine – concentrated due to dehydration
• Decreased urination – not needing to urinate for many hours
• Cold, clammy skin despite hot environment

What Causes It

• Prolonged exposure to high heat and humidity
• Dehydration from inadequate fluid intake
• Physical exertion in hot conditions
• Inability of the body to cool itself through sweating
• Previous heat illness making person more susceptible
• Certain medications affecting heat regulation
• Alcohol consumption (even from the night before)
• Lack of acclimatization to hot weather

What to Do – IMMEDIATE EMERGENCY RESPONSE

DO NOT WAIT – ACT IMMEDIATELY:

1. CALL FOR HELP IMMEDIATELY:
   • Notify supervisor and management NOW
   • Call 911 if symptoms are severe or person is confused
   • Have someone stay with the affected person at all times
2. MOVE TO COOL ENVIRONMENT:
   • Get person to air-conditioned office or vehicle immediately
   • If AC not available, move to deepest shade possible
   • Have them lie down with legs elevated 12 inches
3. BEGIN ACTIVE COOLING:
   • Remove excess clothing and PPE – hard hat, vest, boots, outer layers
   • Apply cool, wet cloths to neck, armpits, groin, and forehead
   • Fan the person to increase evaporative cooling
   • Place ice packs (wrapped in cloth) at neck, armpits, and groin
   • Spray with cool water if misting equipment available
   • Do NOT use ice baths – can cause shock
4. HYDRATION (only if person is fully conscious and alert):
   • Give cool water or electrolyte drinks
   • Have them drink slowly – one cup every 15 minutes
   • DO NOT give fluids if person is nauseous, vomiting, or confused
   • Never force fluids on someone who is not fully alert
5. MONITOR CONTINUOUSLY:
   • Check vital signs every 5-10 minutes
   • Watch for improvement or worsening
   • Be prepared to call 911 if:
     • Symptoms worsen
     • Confusion increases
     • Vomiting prevents fluid intake
     • No improvement within 30 minutes
     • Temperature remains above 103°F
6. DO NOT:
   • Allow person to return to work that day
   • Give alcohol or caffeinated beverages
   • Leave person alone
   • Underestimate the seriousness – heat exhaustion kills

FOLLOW-UP REQUIRED:

• Person must be evaluated by medical professional before returning to work
• Supervisor must complete incident report
• Review work conditions and hydration practices
• Person may need modified duties for several days

4. HEAT STROKE

What It Is

HEAT STROKE IS A LIFE-THREATENING MEDICAL EMERGENCY. The body’s temperature regulation system fails completely. Body temperature rises above 104°F (often 106°F or higher) and can cause permanent brain damage, organ failure, and death within minutes. Survival depends on immediate recognition and emergency medical treatment.

Exact Symptoms

Critical Warning Signs:

• Body temperature 104°F or higher – often 106-110°F
• Hot, dry skin with NO sweating (classic heat stroke) OR hot, moist skin with continued sweating (exertional heat stroke in workers)
• Altered mental state: severe confusion, delirium, bizarre behavior, aggression, combativeness
• Loss of consciousness, unresponsiveness, or coma
• Seizures or convulsions
• Slurred speech – similar to stroke symptoms

Additional Symptoms:

• Rapid, strong pulse initially, then becomes weak
• Rapid, deep breathing or hyperventilation
• Severe headache – described as worst headache of life
• Nausea and vomiting
• Hallucinations or seeing things that aren’t there
• Disorientation – doesn’t know where they are or what day it is
• Inability to walk or stand
• Pupils may be dilated

Behavioral Changes:

• Extreme agitation or combativeness – may fight helpers
• Inappropriate behavior – removing all clothing, wandering
• Lack of coordination – stumbling, falling
• Uncharacteristic personality – may seem intoxicated

What Causes It

• Progression from untreated heat exhaustion
• Sudden overwhelming heat exposure
• Core body temperature rises beyond body’s ability to compensate
• Complete failure of thermoregulation system
• Brain’s hypothalamus (temperature control center) becomes damaged by heat

What to Do – THIS IS A TRUE EMERGENCY

EVERY SECOND COUNTS – DEATH CAN OCCUR IN 10-15 MINUTES:

1. CALL 911 IMMEDIATELY – DO NOT DELAY
   • State “suspected heat stroke” – this gets priority response
   • Give exact location in yard
   • Notify all supervisors and management
2. BEGIN AGGRESSIVE COOLING WHILE WAITING FOR EMS: Primary Goal: Lower body temperature to below 102°F as rapidly as possible
   • Move to coolest location immediately – air-conditioned space is critical
   • Remove ALL clothing except underwear
   • Immerse in cold water if available (tub, tank) OR
   • Cover body with ice-cold wet sheets and fan aggressively OR
   • Apply ice packs to entire body – neck, armpits, groin, back, head OR
   • Continuously pour cold water over person while fanning
   • Place person in front of AC vent with direct airflow
   • Continue cooling until EMS arrives or person begins to shiver
3. POSITIONING:
   • If conscious: sitting or semi-reclined position
   • If unconscious: recovery position (on side)
   • Monitor airway – be prepared for vomiting
4. DO NOT:
   • Give any fluids by mouth (aspiration risk)
   • Leave person alone even for a moment
   • Stop cooling efforts until EMS takes over
   • Underestimate severity – this kills healthy people
5. IF PERSON STOPS BREATHING:
   • Begin CPR immediately
   • Continue until EMS arrives
   • Do not stop cooling efforts during CPR
6. PREPARE FOR EMS ARRIVAL:
   • Have someone guide ambulance to exact location
   • Clear path for gurney/stretcher
   • Provide information: when symptoms started, work activity, last fluid intake, medical history if known

PROGNOSIS:

• Death rate is 10-50% even with immediate treatment
• Permanent brain damage common in survivors
• Multi-organ failure can develop hours or days later
• Recovery requires hospitalization and extended monitoring

CRITICAL UNDERSTANDING: Heat stroke happens FAST. A worker can seem fine, develop confusion within 15 minutes, and be unconscious 10 minutes later. The time window for survival is measured in minutes, not hours.

The Critical Importance of Hydration: Why Daily Water Intake Matters

THE FUNDAMENTAL TRUTH: You Cannot “Catch Up” on Hydration

Many workers make a fatal mistake: They drink minimal water on cool days and try to “catch up” when it’s hot. This strategy kills people.

How Dehydration Actually Works

Your body is approximately 60% water by weight. Every system depends on adequate hydration:

• Blood volume: Water maintains blood volume for circulation
• Temperature regulation: Sweating requires water reserves
• Cellular function: Every cell needs hydration to operate
• Electrolyte balance: Water distributes minerals throughout the body
• Kidney function: Removing waste requires adequate fluid
• Brain function: Even mild dehydration impairs thinking and reaction time

The Dehydration Timeline

What happens when you don’t drink enough water consistently:

Day 1 (Mild Dehydration – 1-2% body water loss):

• Increased thirst
• Decreased urine output
• Darker urine color
• Slight fatigue
• Reduced physical performance (10-15% decrease)
• Impaired temperature regulation begins

Day 2-3 (Moderate Dehydration – 3-5% body water loss):

• Persistent thirst
• Dry mouth and lips
• Concentrated, dark yellow or amber urine
• Significant fatigue and weakness
• Dizziness when standing
• Headaches
• Reduced mental clarity
• 20-30% decrease in physical capability
• Significantly impaired heat tolerance
• Heart rate increases to compensate for low blood volume

Day 4+ (Chronic Dehydration – 5%+ body water loss):

• Severe impairment of all body systems
• Kidney stress and potential damage
• Increased blood viscosity (thickness)
• Strain on cardiovascular system
• Drastically reduced heat tolerance
• Extreme vulnerability to heat illness
• Heat exhaustion can develop in 30-60 minutes of heat exposure
• Heat stroke risk is 3-4 times higher than when properly hydrated

Why “Drinking Only on Hot Days” Fails

Scenario: Worker drinks minimal water Monday-Wednesday (cool days), then faces 95°F Thursday:

• Worker starts Thursday already 3-5% dehydrated
• Body has reduced blood volume and limited sweat capacity
• Drinking water Thursday morning doesn’t restore full hydration (takes 24-48 hours)
• Worker begins strenuous activity in heat while severely compromised
• Heat illness develops rapidly because body cannot cool itself
• Result: Heat exhaustion or heat stroke before lunch

The Science of Proper Hydration

Water intake requirements for scrap yard workers:

BASELINE (Every Day, Regardless of Temperature):

• Minimum 64 ounces (8 cups) for sedentary activities
• 80-100 ounces (10-12 cups) for physical labor jobs
• Start hydrating before you feel thirsty – thirst means you’re already dehydrated

HOT WEATHER ADDITIONS (80°F+):

• Add 16-24 ounces per hour of work in heat
• During strenuous work: 32-40 ounces per hour
• Extreme heat (95°F+): Up to 48 ounces per hour

TOTAL DAILY INTAKE for Scrap Yard Workers:

• Cool days: 80-100 ounces minimum
• Warm days (75-85°F): 120-150 ounces
• Hot days (85-95°F): 150-200 ounces
• Extreme heat (95°F+): 200-250+ ounces

Practical Hydration Guidelines

BEFORE WORK (Critical Foundation):

• Drink 16-20 ounces when you wake up
• Another 16 ounces 30 minutes before starting work
• Your urine should be pale yellow or clear before beginning work

DURING WORK:

• Drink 8 ounces every 15-20 minutes – don’t wait until breaks
• Take sips continuously rather than gulping large amounts
• Never skip scheduled water breaks even if you don’t feel thirsty
• Monitor urine color: Should remain pale yellow throughout the day

HYDRATION SCHEDULE (Sample for 8-Hour Shift in Heat):

• Start of shift: 16 oz
• 30 minutes: 8 oz
• 60 minutes: 8 oz
• 90 minutes: 8 oz
• Morning break: 16 oz
• Continue every 20-30 minutes: 8 oz each
• Lunch: 16-24 oz
• Afternoon: Continue 8 oz every 20-30 minutes
• Afternoon break: 16 oz
• End of shift: 16 oz
• Total: 160-200+ ounces

AFTER WORK:

• Continue drinking – your body needs to replenish reserves
• 16-24 ounces within first hour after work
• Monitor urine color into evening
• Avoid alcohol – severely impairs rehydration and increases next-day heat illness risk

What to Drink

BEST CHOICES:

• Water – primary hydration source
• Electrolyte drinks (sports drinks) – when sweating heavily, alternate with water
• Coconut water – natural electrolytes
• Diluted fruit juice – provides some electrolytes

ELECTROLYTE REPLACEMENT:

• When sweating heavily for more than 2 hours, you need electrolyte replacement
• Drink sports drinks or electrolyte solutions
• Ratio: 1 electrolyte drink for every 2-3 bottles of water
• Salt snacks help retain fluids (pretzels, crackers, salted nuts)

AVOID OR LIMIT:

• Caffeine (coffee, energy drinks) – diuretic effect increases fluid loss
• Alcohol – severe dehydration and impaired heat regulation lasting 12-24 hours
• Sugary sodas – can worsen dehydration
• Pure fruit juice – too concentrated, dilute 50/50 with water

Signs You’re Properly Hydrated

Daily indicators:

• Urinating every 2-4 hours
• Urine color is pale yellow or clear (like lemonade, not apple juice)
• Producing adequate urine volume
• No excessive thirst
• Normal energy levels
• No headaches or dizziness

Signs of Inadequate Hydration

Warning signs you need more water:

• Dark yellow or amber urine (like apple juice or darker)
• Urinating less than 4-5 times per day
• Strong-smelling urine
• Persistent thirst even after drinking
• Headaches, especially afternoon
• Fatigue or sluggishness
• Dry mouth or lips
• Dizziness when standing
• Difficulty concentrating

Acclimatization: Your Body’s Adaptation to Heat

What Is Heat Acclimatization?

Heat acclimatization is the physiological adaptation process where your body becomes more efficient at handling heat stress. This process takes 7-14 days and is critical for safe work in hot environments.

Why Acclimatization Matters

Unacclimatized workers are at 3-4 times higher risk of heat illness during their first week in heat.

What Changes During Acclimatization:

• Sweating begins at lower body temperature – cooling starts sooner
• Sweat rate increases – up to 2-3 liters per hour capacity
• Sweat becomes more dilute – retains more electrolytes
• Heart rate decreases – cardiovascular system adapts
• Blood volume increases – better circulation
• Core temperature stabilizes lower – improved regulation

Acclimatization Schedule

CRITICAL: New employees, returning employees after time off, and all employees at the start of hot season MUST follow graduated exposure:

Days 1-2:

• Maximum 50% of normal workload in heat
• Frequent breaks every 30 minutes
• Extra supervision and buddy system
• Extended hydration breaks

Days 3-4:

• Increase to 60-70% of normal workload
• Breaks every 45 minutes
• Continue close monitoring

Days 5-7:

• Increase to 80-90% of normal workload
• Normal break schedule
• Continue hydration focus

Days 8-14:

• Gradual increase to 100% workload
• Standard operations with heat precautions

MAINTAIN ACCLIMATIZATION:

• Takes only 3-4 days away from heat to lose significant acclimatization
• Weekend breaks slightly reduce acclimatization
• Week-long vacation requires partial re-acclimatization
• Moving from cool indoor work to outdoor heat requires acclimatization

High-Risk Factors: Who Is Most Vulnerable

Medical Conditions Increasing Risk

Workers with these conditions have significantly elevated heat illness risk:

• Heart disease or high blood pressure – impaired circulation
• Diabetes – affects temperature regulation and circulation
• Kidney disease – impaired fluid/electrolyte management
• Obesity – reduced heat dissipation
• Previous heat illness – permanent vulnerability
• Respiratory conditions (asthma, COPD) – difficulty with rapid breathing response
• Skin conditions affecting large areas – impaired sweating
• Fever or recent illness – already stressed system

Medications That Increase Risk

Many common medications impair heat tolerance:

• Blood pressure medications (diuretics, beta-blockers)
• Antihistamines (allergy medications)
• Antidepressants and antipsychotics
• Stimulants (ADHD medications, diet pills)
• Some antibiotics
• Cold medications (decongestants)

REQUIREMENT: If you take any regular medications, inform your supervisor. This is confidential health information used only to provide additional monitoring for your safety.

Lifestyle Risk Factors

• Alcohol consumption – even from previous evening
• Lack of sleep – impairs heat tolerance significantly
• Poor physical fitness – reduced cardiovascular capacity
• Inadequate nutrition – especially low salt intake
• Smoking – impairs circulation and lung function

Age Considerations

• Workers over 50 – reduced heat tolerance and slower adaptation
• Young workers under 25 – often lack experience recognizing heat illness signs
• Both groups require additional monitoring and education

The Absolute Requirement: Report All Symptoms

Why Reporting Is Mandatory

CRITICAL UNDERSTANDING: Heat illness progresses rapidly. What seems like minor discomfort can become life-threatening within 30-60 minutes.

You MUST report to supervisors if you experience:

• Unusual fatigue or weakness
• Dizziness or lightheadedness
• Headache
• Nausea
• Muscle cramps
• Excessive thirst
• Confusion or difficulty concentrating
• Any other unusual symptoms

You MUST report if you observe in coworkers:

• Confusion or disorientation
• Stumbling or coordination problems
• Excessive fatigue
• Stopping sweating in hot conditions
• Personality changes or unusual behavior
• Any concerning symptoms

No Penalties for Reporting

Minichiello Bros Inc Policy:

• No disciplinary action for reporting heat symptoms
• No negative consequences for needing heat breaks
• No pressure to continue working when symptomatic
• Confidential medical information is protected
• Encouraging reports saves lives – you may receive recognition for reporting

Why Workers Don’t Report (And Why You Must)

Common reasons workers don’t report – ALL ARE DANGEROUS THINKING:

❌ “I don’t want to seem weak” → Heat illness is not weakness – it’s physiology ❌ “I’ll just tough it out” → Heat stroke doesn’t care how tough you are ❌ “I don’t want to slow down the crew” → Your death or severe injury stops work completely ❌ “It’s not that bad yet” → “Yet” becomes “critical” in minutes ❌ “I’ll drink some water and be fine” → Advanced heat illness requires immediate medical intervention ❌ “I don’t want to bother anyone” → Responding to heat illness is part of our job

THE TRUTH:

• Reporting early symptoms allows simple interventions (rest, fluids, cooling)
• Waiting until symptoms are severe requires 911 calls and hospitalizations
• Every heat stroke death is preventable if caught at the heat exhaustion stage
• Your coworkers want you to report – they’d rather have you safe than trying to prove yourself

Real-World Consequences: Why This Matters

Heat Stroke Fatality Statistics

• Heat stroke kills approximately 700 workers annually in the United States
• Construction and extraction workers (including scrap yard workers) account for 35% of deaths
• 66% of heat deaths occur in the first week of working in hot conditions
• Death rate is 10-50% even with immediate medical treatment
• Most victims are otherwise healthy males aged 20-50

Case Example (Composite of Real Incidents)

Worker, age 34, scrap yard laborer:

• Thursday afternoon, 94°F temperature
• Had been working normally all morning
• Drank minimal water Monday-Wednesday (cool days)
• Started Thursday already dehydrated
• 2:00 PM – Coworker noticed he seemed “off” but didn’t report
• 2:15 PM – Worker became confused, aggressive when offered water
• 2:20 PM – Collapsed, unconscious
• 2:22 PM – 911 called, CPR started
• 2:35 PM – EMS arrived, body temperature 108°F
• Outcome: Death in hospital 36 hours later from multi-organ failure

Contributing factors:

• Chronic dehydration from inadequate water intake on cooler days
• No acclimatization protocol
• Coworker hesitated to report initial signs
• 15-minute delay from first symptoms to emergency call
• Supervisor wasn’t informed until after collapse

Preventable? Absolutely.

• Proper daily hydration would have provided physiological reserves
• Reporting initial signs would have allowed intervention at heat exhaustion stage
• Immediate cooling at first sign of confusion might have prevented progression

Long-Term Disability

Heat stroke survivors often face:

• Permanent brain damage and cognitive impairment
• Chronic kidney disease requiring dialysis
• Heart damage and cardiovascular disease
• Coordination and balance problems
• Inability to tolerate heat (permanently heat-sensitive)
• Chronic fatigue syndrome
• Unable to return to physical labor jobs

A heat stroke “survivor” often faces a lifetime of disability.

Special Considerations

Humidity’s Role

High humidity drastically increases heat stress:

• Prevents sweat evaporation (body’s primary cooling mechanism)
• 90°F with 70% humidity feels like 105°F
• Workers can overheat even without direct sun exposure
• Indoor areas without airflow become dangerous
• Monitor heat index, not just temperature

Protective Clothing Paradox

PPE is required for safety but increases heat stress:

• Creates insulated microenvironment around body
• Blocks evaporative cooling
• Increases metabolic heat Solution: Take more frequent breaks to remove PPE safely and cool down

Equipment and Machinery Heat

Additional heat sources in scrap yards:

• Engine heat from equipment
• Exhaust from vehicles
• Radiant heat from cutting/welding operations
• Hot metal from processing Workers near these sources need extra monitoring and breaks

First Day Back After Time Off

Critical vulnerability period:

• Lost acclimatization over weekend/vacation
• May have different hydration habits at home
• Body needs to readapt Requires graduated return to full workload

Emergency Contact Information

FOR ANY HEAT ILLNESS EMERGENCY:

1. Call 911 immediately if symptoms include:
   • Confusion or altered mental state
   • Loss of consciousness
   • Seizures
   • Body temperature above 103°F
   • Inability to drink fluids
2. Always connect a supervisor or Facility Manager
