Heat Stroke First Aid: Emergency Action Guide for Gold Coast Workers and Employers (2026)
By SKLD Training - 2026-04-02
If someone near you is confused, has hot dry skin, or collapses in the heat - call 000 immediately, move them to shade, and start cooling aggressively. This rapid-reference guide gives Gold Coast workers and employers a clear decision tree for heat exhaustion versus heat stroke, step-by-step action plans, scenario-based protocols, and the common mistakes that cost lives.
If someone is confused, has stopped sweating despite being in extreme heat, or collapses - call 000 first. Then move them to shade and begin cooling immediately. Do not wait to see if they improve. Heat stroke can be fatal within minutes without intervention. This guide gives you the action steps you need right now.
Is It Heat Exhaustion or Heat Stroke? 60-Second Decision Tree
This is the single most important question in a heat emergency. The wrong answer leads to the wrong response. Use this check before anything else:
| Check This | Heat Exhaustion | Heat Stroke - Call 000 NOW |
|---|
| Mental state | Alert and coherent, may feel weak or dizzy | Confused, agitated, slurred speech, or unconscious |
| Skin | Pale, cool, and clammy - sweating heavily | Hot, flushed, red - may be dry or wet |
| Core temperature | Elevated but below 40°C | Above 40°C (often 41–42°C) |
| Behaviour | Nausea, headache, muscle cramps | Seizures, collapse, unresponsive |
| Pulse | Rapid and weak | Rapid and strong early, then deteriorating |
| Your action | Rest, cool, monitor - call 000 if deteriorates | Call 000 first. Cool aggressively while waiting |
Rule of thumb: If you are unsure which condition you are dealing with - treat it as heat stroke. A call to 000 costs nothing. Delayed treatment for heat stroke can cause permanent brain damage or death.

Heat Exhaustion: 7-Step Action Plan
Heat exhaustion is serious but manageable if caught early. Work through these steps in order and keep watching for signs of deterioration throughout.
- Move immediately (0–60 seconds): Get the person out of the sun and heat right now. Move to shade, an air-conditioned vehicle, or a cool building. Do not let them keep working through it.
- Call for help (within 1 minute): Alert a supervisor or colleague. If you are alone and the person is deteriorating, call 000 now - do not wait for step 7.
- Remove excess clothing (1–2 minutes): Loosen or remove tight clothing around the neck, chest, and waist. Remove PPE such as hard hats and high-vis vests to allow heat to escape the body.
- Begin cooling (immediately and ongoing): Apply cool (not ice cold) water to skin. Focus on the neck, armpits, and groin where blood vessels are close to the surface. Fan the person continuously to boost evaporative cooling.
- Position correctly (2–3 minutes): Have the person lie down on a cool surface. If they feel faint, elevate their legs slightly unless there is an injury. Do not leave them sitting upright and unsupported.
- Rehydrate if conscious (3–5 minutes): If the person is fully alert and not vomiting, give small sips of cool water every few minutes. Do not force fluids. Do not give sports drinks, alcohol, or caffeinated drinks.
- Monitor continuously: Check mental state every 2 minutes. If the person becomes confused, stops responding normally, or their condition worsens at any point - call 000 immediately and escalate to the heat stroke protocol below.
Most people with heat exhaustion recover within 30 minutes with these measures. Even if they seem fine, arrange medical review. Heat exhaustion weakens the body's heat regulation and can recur the same day.
Heat Stroke: Emergency Protocol
Heat stroke is a life-threatening emergency. Every minute of elevated core temperature causes additional damage to the brain, kidneys, and heart. The treatment goal is rapid cooling - and it starts before the ambulance arrives.
- Call 000 first - before anything else: State "I have a person with suspected heat stroke." The operator will guide you. Do not hang up.
- Move to shade or cool environment: While someone calls 000, get the person out of the heat as quickly and safely as possible.
- Remove clothing immediately: Strip off as much clothing as safely possible. Maximum skin exposure maximises cooling. Remove PPE, boots, socks.
- Begin aggressive cooling - do not wait: The following methods are listed in order of effectiveness. Use whichever is available and start immediately:
- Cold water immersion: If conscious and cooperative, place in a cold-water bath or tub. Most effective for exertional heat stroke - use if available on site.
- Ice packs to neck, armpits, and groin: Apply simultaneously to all three sites. Cover with a damp cloth if direct ice contact is painful. Replace frequently.
- Wet the entire body with cold water and fan: Pour cold water over the person continuously and fan hard. This is your go-to on construction sites and outdoor events where immersion is not possible.
- Cold wet sheets: Wrap the person in cold wet sheets and fan aggressively.
- Position for airway safety: If conscious - lay flat, legs slightly elevated. If unconscious but breathing - recovery position on their side. If not breathing - start CPR following DRSABCD and continue until paramedics arrive.
- Do not give fluids to an unconscious person: Risk of aspiration is high. Wait for paramedics to establish IV access.
- Do not stop cooling until temperature drops below 38.5°C or paramedics take over: Heat stroke patients can re-heat rapidly. Maintain cooling efforts the entire time you are waiting.
- Do not transport yourself unless 000 tells you to: Heat stroke patients deteriorate rapidly. Paramedic management during transport saves lives.

Scenario-Based Responses: What to Do Where You Are
The correct first response varies slightly depending on your environment and what resources are available. Here are the four most common Gold Coast heat emergency settings.
Construction Site
A worker on the roof becomes confused and staggers. Get another worker to call 000 while you physically support the patient and guide them down or call them down immediately - do not leave them at height. Once down: shade under scaffold or in the site office, remove PPE and work gear, get the site's first aid kit cold packs onto the neck and armpits, run the site hose on cold setting over their torso. Nominate one person to meet the ambulance at the site gate and direct them in.
Outdoor Event
A staff member or attendee collapses or becomes incoherent in a crowd. Call 000 and activate your event emergency plan simultaneously. Clear a space around the patient - crowd pressure generates additional heat. Use event water points or misting tents for cooling. Direct your trained first aiders to the patient. The event safety officer should meet paramedics at the closest access point and ensure the route is clear.
Fitness Session
A personal training client stops responding to instructions mid-session or behaves erratically. Stop the session immediately. Move to the nearest shade or air-conditioned space. Call 000. Begin cooling with available water. Do not assume they are dehydrated and push fluids if they are confused - altered mental state means heat stroke, not just heat exhaustion. Notify the gym or facility manager to assist.
School Sports Day
A student collapses on the oval or appears confused and unsteady during a race. Have another staff member call 000 while you move the student to shade. Apply cool wet cloths from your first aid kit. Keep other students away to reduce crowd heat. Contact parents immediately after calling 000 - do not wait until the ambulance arrives. Even if the student appears to recover quickly, insist on ambulance assessment. Children can deteriorate rapidly.
When to Call 000: Specific Triggers
Call 000 immediately - without hesitation - if any single one of these is present:
- Confusion, disorientation, or any change in mental state
- Slurred or incoherent speech
- Unresponsive or loses consciousness for any period
- Seizure or convulsion
- Hot, dry skin (not sweating) despite obvious heat exposure
- Rapid deterioration despite 5–10 minutes of cooling
- Vomiting while showing other signs of heat illness
- Any doubt at all about whether it is heat exhaustion or heat stroke
If you call 000 and it turns out to be heat exhaustion - that is a good outcome. If you wait and it was heat stroke - the outcome may be irreversible. Always err toward calling.
What NOT to Do: Common Mistakes That Make It Worse
Incorrect first aid in a heat emergency can accelerate organ damage and reduce survival chances. Avoid all of the following:
- Do not tell them to walk it off or push through: Once heat illness signs appear, the body's thermoregulation is already compromised. Continued exertion in heat is dangerous.
- Do not use only warm or tepid water: Cool or cold water is more effective for lowering core temperature. Warm water slows the process.
- Do not give fluids to anyone showing confusion: Aspiration risk is high. Fluids are for alert, conscious persons only.
- Do not put them in an ice bath if they are unconscious: Cold shock response in unconscious patients is dangerous. Use ice packs and cold water instead.
- Do not leave them alone at any point: Heat stroke can cause sudden cardiac arrest. Maintain visual contact and monitor breathing continuously.
- Do not stop cooling because they "seem better": Core temperature can remain dangerous even when the person becomes calmer or more coherent. Continue until paramedics confirm it is safe to stop.
- Do not delay calling 000 to try first aid alone: Call first, treat second. These actions happen in parallel.
- Do not drive a heat stroke patient to hospital yourself: Unless directed by 000 operators in a remote location. Paramedics manage en route deterioration - your car cannot.
Cooling Methods Ranked by Effectiveness
| Method | Effectiveness | Best For | Available On Site? |
|---|
| Cold water immersion | Highest - fastest core cooling | Exertional heat stroke, conscious patient | Requires tub or pool |
| Ice packs to neck, armpits, groin | High - targets major blood vessels | All heat stroke scenarios | From first aid kit |
| Cold water dousing + fanning | High - effective and scalable | Outdoor sites, events, no tub available | Hose, bucket, spray bottle |
| Cold wet sheets + fanning | Moderate to high | Indoors, limited water access | Towels + cold water |
| Air conditioning + fan | Moderate - useful as supplement | All scenarios as secondary measure | Vehicle, site office |
| Cool cloths to forehead only | Low - insufficient alone | Heat exhaustion comfort only | Always available |

Why First Aid Course Training Covers Heat Emergencies
Heat-induced illness is a core scenario in HLTAID011 Provide First Aid - the standard nationally recognised first aid qualification. Workers who complete HLTAID011 will have practised recognising heat exhaustion and heat stroke, applying cooling techniques, managing an unconscious heat casualty using DRSABCD, and making the 000 call decision. (HLTAID011 on training.gov.au)
Classroom instruction alone is not enough. The practical component of HLTAID011 builds the automatic responses that work under pressure on a hot construction site or at a summer event - when adrenaline is high and time is short. For outdoor workplaces, this is not an optional extra. Under the WorkSafe QLD First Aid in the Workplace Code of Practice, outdoor high-risk workplaces must have qualified first aiders holding HLTAID011 on every shift.
SKLD Training delivers HLTAID011 onsite to outdoor and construction teams across the Gold Coast. Training can be scheduled around site phases and shift patterns to avoid workflow disruption.
Gold Coast Specific: High-Risk Suburbs, Summer Temperatures, and Industries
The Gold Coast averages over 280 sunny days per year. Between November and March, apparent temperatures (heat index combining temperature and humidity) regularly exceed 35–40°C - the range where heat stroke risk escalates sharply for workers doing physical tasks. The following suburbs and industries carry the highest heat emergency risk on the Gold Coast:
| Industry | Gold Coast Hotspot Suburbs | Key Heat Risk Factors |
|---|
| Residential construction | Coomera, Pimpama, Ormeau, Helensvale | Roofline work, no shade, PPE heat trapping, fast-tracked schedules in summer |
| Commercial construction | Southport, Labrador, Robina, Varsity Lakes | Scaffolding radiant heat, concrete pours in direct sun, limited rest areas |
| Outdoor events and festivals | Surfers Paradise, Broadbeach, Burleigh Heads | Crowd density amplifies heat, staff labour during peak sun hours, alcohol-affected attendees |
| Fitness and personal training | Burleigh Heads, Surfers Paradise, Southport | Client exertion in summer heat, back-to-back sessions, beachfront exposure |
| School sports and outdoor education | Robina, Helensvale, Coomera, Varsity Lakes | Children's reduced thermoregulation, competitive pressure masking symptoms |
| Landscaping and grounds maintenance | Robina, Burleigh Heads, Southport, Coomera | Continuous sun exposure, equipment heat, solo workers without buddy system |
Frequently Asked Questions
What are the first signs of heat stroke?
The earliest warning sign of heat stroke that distinguishes it from heat exhaustion is a change in mental state - confusion, agitation, unusual behaviour, or difficulty following instructions. Other early signs include hot flushed skin (which may or may not be dry), a strong rapid pulse, and a body temperature above 40°C if measurable. If a person in the heat starts behaving oddly or cannot answer simple questions clearly, treat it as heat stroke immediately and call 000.
How do you treat heat stroke before the ambulance arrives?
Call 000 first, then begin aggressive cooling simultaneously. Remove the person's clothing to maximise skin exposure. Apply the most effective cooling method available: cold water immersion if conscious and cooperative, or continuous cold water dousing combined with fanning. Place ice packs at the neck, armpits, and groin. If unconscious but breathing, place in the recovery position. If not breathing, start CPR. Do not give fluids orally. Do not stop cooling. Maintain this until paramedics arrive and take over.
What is the difference between heat exhaustion and heat stroke?
Heat exhaustion is a serious heat-related illness where the person is still conscious and coherent - they sweat heavily, have pale clammy skin, and may feel dizzy, nauseous, or weak. It is managed with rest, shade, cooling, and fluids. Heat stroke is a medical emergency where core temperature exceeds 40°C and the person shows altered mental state, confusion, or loss of consciousness. Heat stroke requires an immediate 000 call and aggressive cooling. The key distinction: if the person cannot answer simple questions clearly, it is heat stroke.
Can heat stroke cause permanent damage?
Yes. Heat stroke can cause permanent damage to the brain, kidneys, liver, and heart. The longer core body temperature remains above 40°C, the more severe the damage. Survival without permanent injury depends on how quickly cooling begins. This is why calling 000 immediately and cooling aggressively before the ambulance arrives is so important - every minute matters. Some heat stroke survivors experience lasting cognitive impairment, kidney disease, or cardiovascular complications even after hospital treatment.
What temperature causes heat stroke?
Heat stroke is defined by a core body temperature above 40°C - but this can occur at air temperatures well below that, especially when physical exertion, high humidity, direct sun exposure, and inadequate hydration combine. On the Gold Coast in summer, apparent temperatures (the heat index felt by the body) can reach 35–42°C on extreme days. Physical workers doing heavy tasks in these conditions can reach dangerous core temperatures within an hour. The ambient temperature does not need to be 40°C for heat stroke to occur.
Does a first aid course teach you how to handle heat stroke?
Yes. Heat-induced illness including both heat exhaustion and heat stroke is covered in HLTAID011 Provide First Aid as a practical scenario. Participants learn to differentiate between the two conditions, apply the appropriate cooling techniques, manage an unconscious heat casualty using the DRSABCD framework, and make the 000 call decision. SKLD Training delivers HLTAID011 on the Gold Coast with onsite options for outdoor workplaces and construction teams. Check available course dates at SKLD Training.
