I was strolling through the office one day....
SYDNEY (Reuters) - An
Australian man built up a 40,000-volt charge of static electricity in his
clothes as he walked, leaving a trail of scorched carpet and molten plastic and
forcing firefighters to evacuate a building.
SYDNEY (Reuters) - An Australian man built
up a 40,000-volt charge of static electricity in his clothes as he walked,
leaving a trail of scorched carpet and molten plastic and forcing firefighters
to evacuate a building.
Frank
Clewer, who was wearing a woolen shirt and a synthetic nylon jacket, was
oblivious to the growing electrical current that was building up as his clothes
rubbed together.
When he walked
into a building in the country town of Warrnambool in the southern state of
Victoria Thursday, the electrical charge ignited the
carpet.
"It sounded almost like
a firecracker," Clewer told Australian radio Friday. "Within about five
minutes, the carpet started to
erupt."
Employees, unsure of the
cause of the mysterious burning smell, telephoned firefighters who evacuated the
building.
"There were several
scorch marks in the carpet, and we could hear a cracking noise -- a bit like a
whip -- both inside and outside the building," said fire official Henry
Barton.
Firefighters cut
electricity to the building thinking the burns might have been caused by a power
surge.
Clewer, who after leaving
the building discovered he had scorched a piece of plastic on the floor of his
car, returned to seek help from the
firefighters.
"We tested his
clothes with a static electricity field meter and measured a current of 40,000
volts, which is one step shy of spontaneous combustion, where his clothes would
have self-ignited," Barton
said.
"I've been firefighting
for over 35 years and I've never come across anything like this," he
said.
Firefighters took
possession of Clewer's jacket and stored it in the courtyard of the fire
station, where it continued to give off a strong electrical
current.
David Gosden, a senior
lecturer in electrical engineering at Sydney University, told Reuters that for a
static electricity charge to ignite a carpet, conditions had to be
perfect.
"Static electricity is
a similar mechanism to lightning, where you have clouds rubbing together and
then a spark generated by very dry air above them," said Gosden.
