Chest Heaviness on a Roof in June
In the second week of June, Ram Kishore, a 48-year-old mason, has been working on a concrete roof since 8 a.m. in 43 C heat. At about 2 p.m. he sits down and complains of heaviness behind the breastbone that spreads to his left arm and jaw. He is sweating heavily, looks pale-grey and feels nauseated. His co-workers say he has drunk only half a bottle of water since morning, that he has smoked beedis for 25 years, and that last week he had a similar but milder episode that went away in ten minutes. One man offers him cold salted lemon water, another wants to make him vomit, and a third says it is only 'loo lagna' and he should be taken home to rest. The nearest CHC is 12 km away; there is a tractor trolley and one mobile phone with signal.
1. Distinguish the features that fit heat illness from those that fit a heart attack, and state your leading judgement with reasons.
Read the worked answer
Features that fit heat illness
- Work in 43 C, long hours, very little water, heavy sweating. Heat exhaustion gives thirst, weakness, dizziness, headache, cramps and a raised pulse; heat stroke adds confusion, hot dry skin and very high body temperature. None of these alone explains pain spreading to the jaw.
Features that fit a heart attack (acute coronary syndrome)
- Heaviness behind the breastbone, not sharp pain, radiating to the left arm and jaw.
- Cold sweats, pallor, nausea.
- A 25-year history of beedi smoking, which damages the coronary arteries.
- A similar short episode last week that settled in ten minutes, a warning sign of unstable angina.
- Pain is not relieved by sitting down and resting in the shade.
Judgement: treat this as a cardiac emergency until a doctor proves otherwise. Heat and dehydration can themselves trigger a heart attack, because dehydration concentrates the blood and raises clotting and heart rate, so the two are not alternatives. The safe rule is the dangerous diagnosis first: the cost of wrongly treating a heart attack as heat exhaustion is death, while the cost of the reverse is only a wasted trip.
Do not wait for vomiting or for the pain to become severe; by then muscle has already been lost.
2. Set out the first aid and transport decisions for the next sixty minutes, and name the actions you would actively forbid.

Do
- Stop all work. Make him sit or lie semi-recumbent in shade; let him choose the position that eases breathing.
- Loosen his shirt, fan him, put a wet cloth on his forehead and neck while keeping him from chilling.
- If he is fully conscious, give small sips of water; if the salted lemon water is already prepared, a few sips are acceptable, but it must not delay transport.
- Call 108 or the CHC on the mobile and state 'chest pain, 48-year-old man, sweating, known smoker'. Ask them to keep an ECG ready.
- Move him lying or semi-recumbent on the tractor trolley with a cushion, with one person travelling beside him; the ride should be slow and quiet, not a standing ride on a bumpy road.
- Note the time of onset, and tell the doctor about last week's ten-minute episode.
Forbid
- Do not make him vomit, and do not give salt water or anything by mouth if he becomes drowsy.
- Do not let him walk, climb, or go home to rest.
- Do not massage his chest or press his arm.
- Do not give aspirin or any other medicine on your own; leave it to the doctor or the ambulance team.
- Do not wait to see if the pain settles, as it did last week.
The first sixty to ninety minutes decide how much heart muscle survives.
3. The contractor says heat is part of the job. What low-cost changes should be made at this worksite, and where does an employer's duty begin?
Read the worked answer
Water and salt
- Place a covered water pot at the work point, not 100 metres away; the awkward distance is why he drank so little.
- Give a scheduled break of 10-15 minutes every hour, with about 250 ml of water each time; thirst alone is a poor guide in heat.
- Provide ORS or salted buttermilk and salted food at lunch, because sweat loses salt as well as water.
Timing and shade
- Shift heavy concrete work away from 12 noon to 4 p.m.
- Provide a shaded rest area with a fan or a wet-mat cooler, and let workers acclimatise over the first week of summer.
People and training
- Work in pairs, so one person notices when another becomes confused or stops sweating.
- Train the crew in the danger signs of heat stroke and in calling 108.
The duty
- Under the Factories Act and state labour rules, and under the Building and Other Construction Workers Act, drinking water, rest breaks, first-aid boxes and trained first-aiders are minimum legal requirements, not charity. Heat is a hazard that the employer must control, and a worker who collapses on site should be treated as a workplace incident and reported, not sent home as a private illness.
