Proximate Cause: Natural Heating in Stored Husk and the Fire Exclusion
A coir products manufacturer in Alappuzha stores coconut husk in a masonry godown insured under a Standard Fire and Special Perils Policy with Strike, Riot, Malicious Damage and Terrorism cover attached. The exclusion for loss caused by the insured property's own fermentation, natural heating or spontaneous combustion was not bought back by endorsement. On 12 May a watchman reported smoke from the godown. The fire brigade excavated a twelve-foot stack of husk that had been stored for seven weeks, found the seat of the fire deep inside the stack, and extinguished glowing embers and small flames that appeared only when the stack was broken open. There are no electrical fittings in the godown and no external ignition source was found. Thermometer readings taken by the insured had been rising for ten days but were not reported to the insurer or acted upon. The insured claims Rs 1.20 crore for stock, Rs 18 lakh for removal of debris and Rs 2.50 lakh paid to the fire brigade. The damaged husk has been sold as manure for Rs 60,000.
1. Is the stock loss payable? Identify the operative exclusion and set out the proximate cause reasoning, including the distinction between fire and heating without ignition.

No - the claim is excluded. The Standard Fire and Special Perils Policy excludes loss or damage caused by or resulting from the insured property's own fermentation, natural heating or spontaneous combustion, and that exclusion was not deleted here. The Strike, Riot, Malicious Damage and Terrorism cover is irrelevant: there was no strike, riot, malicious act or terrorism on the facts.
Proximate cause. What matters is what actually caused the damage, not what was happening when it was discovered. The surveyor's findings - the seat deep inside the stack, seven weeks of storage, a temperature that had been climbing for ten days, no electrical fittings, no external ignition source - point to microbiological heating within the husk. That is natural heating or spontaneous combustion, a specifically excluded peril.
Fire versus heat. In a fire policy, 'fire' means actual ignition and burning, not mere charring or scorching. Some flame appeared when the stack was broken open and air entered, but that is a consequence of the excluded heating, not an independent insured peril. The exclusion therefore catches the whole loss even though flames were eventually seen. The insured bears the burden of showing that an insured peril was the proximate cause, and it cannot do so.
Note on the unreported temperature. Negligence by the insured is not itself a defence under a fire policy, but the ten-day rising trend strengthens the finding that the cause was internal heating rather than a sudden, accidental ignition.
2. Deal with the removal of debris, fire brigade charges and salvage: what would be payable if the stock loss had been admissible, and what happens to these items now?
Read the worked answer
As matters stand, all three items fail with the principal claim. Expenses ancillary to an excluded loss cannot be recovered; the insurer does not pay the cost of clearing up damage it is not liable for.
If the loss had been admissible:
- Removal of debris (Rs 18 lakh). Payable only if the debris-removal clause is attached; where it is, its limit (commonly 2% of the claim amount or the sum insured, whichever is lower) applies, and the cost forms part of, not an addition to, the sum insured. On a Rs 1.20 crore loss a 2% cap gives roughly Rs 2.40 lakh, leaving most of the Rs 18 lakh uninsured - a point to settle at proposal stage, not at claim stage.
- Fire brigade charges (Rs 2.50 lakh). Reasonable expenses incurred to extinguish the fire and minimise the loss are payable within the sum insured, provided they were necessarily incurred; they are not a separate head of damage.
- Salvage (Rs 60,000). The net loss is the loss less salvage. The insurer is entitled to take over the salvage; if the insured has already sold the damaged husk as manure, that Rs 60,000 is deducted from the claim or held for the insurer's account.
Also check whether input tax credit was taken on the destroyed stock, since that affects the quantum of the stock loss.
3. Recommend how this risk should be handled at renewal so that the cover and the hazard are aligned.
Read the worked answer
The mismatch is structural: a self-heating commodity insured on a wording that excludes exactly the peril that destroys it. Recommending controls without fixing the cover leaves the insured uninsured next time as well.
Cover. Ask underwriters specifically whether the spontaneous combustion exclusion can be deleted for stored coconut husk; where it can, expect a materially higher rate, a sizeable deductible and warranties. If it cannot, say so in writing and record the advice, so the insured cannot later say it believed it was covered.
Risk controls to write into the policy as warranties or conditions:
- Limit stack height and width and provide forced or natural aeration; rotate stock within four to six weeks rather than seven.
- Install temperature probes at depth with a documented daily logging routine and a written trigger for breaking open and cooling a stack.
- No smoking, no hot work, and no electrical fittings in the storage area.
- Segregate new and old stock so a heating incident does not consume the whole godown.
- A debris-removal clause with a realistic limit, and a clear internal protocol for calling the fire brigade.
Underwriting action. Price for the residual risk, increase the deductible, and re-inspect before renewal. If the insured will not accept the controls and the exclusion cannot be bought back, the honest position is that the risk should not be written.
