Photograph a lit can in daylight and try to tell
A can of chafing fuel is a 6-hour fire you cannot see
Alcohol burns with a flame that is close to invisible in daylight. That is a property of the fuel, and no sign or training changes it.
Stand a lit can of ethanol gel on a sunny terrace and ask three people whether it is burning. Expect three different answers. Alcohol flames are pale blue and nearly transparent; in bright light they disappear.
Why that is the central hazard
Every injury mechanism in the record depends on it. Refueling a can you believe is out. Reaching across a flame you cannot see. Putting a can down that is still alight. Product-liability lawsuits over alcohol-fuelled tabletop fire pits turn on the same invisible-flame problem, in the same chemistry.
Six hours of it
A large can burns for up to six hours. For a whole service the line carries a row of small fires that most of the room cannot see, at hand height, beside a self-service crowd.
What visible looks like
A cordless cell has a status light that tells you it is on. A water-activated pack has no flame at all. Either one can be seen for what it is from across the room.
