Bottled gas had a hard October. A cylinder warehouse in Faridabad district in northern India burst several cylinders in sequence on 21 October, burning two workers. A fortnight earlier, a cylinder godown in Mymensingh, Bangladesh started a fire that gutted a century-old cinema hall and about twenty neighbouring shops. On 24 October, a storage room in Bengaluru exploded when its owner opened the door onto an overnight leak, injuring three people including a child. Three sites, three countries, one fuel handled in small depots by small teams.
The Leak Somebody Reported
The complaint filed after the Faridabad fire alleges that the two workers told the owner about a cylinder leak before the blaze, and that no safety equipment was provided. Police are still investigating, and an allegation is not a finding. The complaint still sketches the staffing reality of depots across South Asia and much of the emerging world: a storekeeper and an assistant, no detection system, sometimes no gloves at all. For a distributor selling into this market, gloves and boots are not an accessory to a PPE programme; in most depots they are the entire programme, and they cost far less than a burned hand and a suspended licence.
The Liquid Phase Does the Damage
LPG is stored as a liquid under pressure, and a leak releases it in two phases at once. The liquid flashes violently: propane boils at about minus 42 degrees Celsius, so escaping liquid chills skin on contact, and the resulting cold burn can look exactly like a heat burn. Butane boils near zero. Every routine task, from soapy-water valve checks to fitting regulators to carrying cylinders chilled by expansion, puts hands against that liquid or the metal it has frozen. Thin disposable gloves rated for hygiene rather than thermal contact offer nothing here.
The vapour draws its own map. Propane and butane are heavier than air, so escaped gas does not rise and disperse; it pours downward, pools at ankle height and flows along floors toward the nearest ignition source. A worker's boots sit inside that layer for the whole shift.
Boots Work Where the Vapour Lives
Because the hazard lives at floor level, footwear decisions carry unusual weight at an LPG depot. Soles should be antistatic, so a spark does not walk into the pooled layer with the wearer. Uppers need no exposed metal, treads that stay grippy on oily concrete, and no laces, which soak up liquid and burn. Toe caps matter too: cylinders weighing fifteen to thirty kilograms are lifted by hand all day, and a dropped cylinder on an unprotected foot ends the shift and possibly the depot's.
A Short Buying List
Four lines cover most of it.
- Ask for contact-cold performance, such as EN 511 data, alongside abrasion resistance; leather alone soaks liquid, freezes and goes stiff.
- Specify antistatic gloves for regulator and valve work, with dexterity proven on the actual fittings.
- Order boots with antistatic soles, toe caps and cleated, oil-resistant outsoles, across a full size run.
- Write a change-out rule: any glove frozen or soaked by flashing liquid is discarded, and stock is sized by daily cylinder movements rather than headcount.
Cylinder depots keep multiplying as clean-cooking programmes expand. The fuel is ordinary; its failure modes are not. Buyers who write the cold liquid and the heavy vapour into the specification will sell protection that matches the incident rather than the brochure.
