Collapsed Mason on a 46 °C Slab - Heat Stroke or Exhaustion?

On 26 May at 13:10 the temperature at a construction site in Hisar is 46 °C. A 42-year-old mason who has been working on the third-floor slab since 08:00 without a break suddenly stops speaking clearly, stumbles and sits down. When the guard reaches him he is confused, his skin is hot and dry, his face is flushed, and he cannot stand without support. A helper says the man "hasn't passed urine since morning" and that he vomited two glasses of water given to him a few minutes ago. Another worker says, "It is only heat exhaustion, give him ORS and let him rest, no need for an ambulance - it costs money." The site has one cooler in the labour shed 60 m away, no shade on the slab, and the nearest CHC is 14 km away. The guard has a first-aid box with ORS, bandages, a thermometer and no ice.

1. Is this heat exhaustion or heat stroke? Justify using the specific signs in the scenario.

Read the worked answer

This is heat stroke, and the signs decide it, not the label the workers are using:

  • Altered mental state - he cannot speak clearly, is confused and cannot stand. Heat exhaustion causes weakness, dizziness and heavy sweating but the worker stays alert and oriented. Confusion is the red line.
  • Hot, dry skin with a flushed face in a person working in 46 °C suggests the sweating mechanism is failing. (Heat stroke can also present with sweating, so absence of sweat is not required for the diagnosis - its presence would not rule stroke in.)
  • Vomiting after oral fluids and no urine since morning point to severe dehydration and developing kidney strain.
  • A core temperature around or above 40 °C would confirm it; the guard's thermometer may read low if it is an axillary/ear device and the reading is taken late, so a 'normal' reading must not be used to downgrade a confused, hot patient. Practical conclusion: treat as heat stroke. Heat stroke kills through delayed cooling and delayed transport; heat exhaustion does not cause unconsciousness. When in doubt, treat as stroke.

2. Give the first-aid steps in order for the first ten minutes, including what must NOT be done.

DO, in this order:

  1. Call 108 immediately (and tell the site supervisor). Cooling and transport start together - one is not a substitute for the other, and the CHC is 14 km away.
  2. Move him to shade or the cooled labour shed; do not leave him on the hot slab. Loosen/remove excess clothing and tool belt.
  3. Cool aggressively: wet his skin and fan him, put cool wet cloths on the neck, armpits and groin, and use the cooler's air. Evaporative cooling plus fanning is the best option available without ice.
  4. Position and monitor: recovery position if he is vomiting or drowsy but breathing; check breathing and responsiveness continuously; be ready to start CPR if he stops breathing.
  5. Record the time of collapse, signs, actions and the ambulance reference. DO NOT:
  • Force ORS or water into a confused or vomiting person - aspiration risk; he has already vomited.
  • Use alcohol rubs, or leave him alone 'to rest'.
  • Give painkillers or any medicine from the box.
  • Wait for the family's or contractor's permission before calling 108.

3. How should the guard deal with the 'no ambulance, it costs money' pressure, and what does he hand over and document?

Read the worked answer

The pressure is not a clinical argument, it is a cost argument - answer it on duty grounds.

  • The guard's post order and first-aid training make summoning emergency medical help for a collapsed worker a duty, not a favour. The 108 service is free; any bill at the CHC is the employer's/contractor's liability, not a reason to withhold care.
  • Say it plainly and once to the objecting worker: 'He is confused and cannot stand - that is heat stroke. I have called 108; please inform the site engineer and his family.' Do not argue at length; do not hand the phone or the decision to the crowd.
  • If the contractor or supervisor tries to stop the ambulance or move the man to the labour shed and leave him, note the names and exact words, call the site engineer, and inform the agency control room. Obstructing medical help to an injured worker is a serious liability for the employer under safety law. Handover and record: to the ambulance/CHC staff - what happened, time of collapse, signs observed, cooling done, fluids given and vomited, and the guard's name and phone. In the site register and incident report - the same facts, the names of the persons who objected, the time 108 was called and the vehicle number, and the corrective point that no work-rest cycle or shade existed on the slab in a 46 °C heat wave.
