Airline passenger suffers burns after headphones catch fire during flight from Beijing to Melbourne

March 15, 2017

Mar 15: The Australian Transport Safety Bureau (ATSB) has issued a passenger warning after a woman's headphones caught fire during a recent flight from Beijing to Melbourne. The airline passenger suffered burns to her face and hands after her battery-powered headphones exploded while she was sleeping during the long-haul flight.

The woman, who was not identified, said she was listening to music when she dozed off and was awoken by the sound of a loud explosion about two hours into the flight.

"As I went to turn around I felt burning on my face," she said, the ATSB reported. "I just grabbed my face which caused the headphones to go around my neck. I continued to feel burning so I grabbed them off and threw them on the floor. They were sparking and had small amounts of fire.

"As I went to stamp my foot on them the flight attendants were already there with a bucket of water to pour on them. They put them into the bucket at the rear of the plane."

Officials identified the lithium-ion battery in the device as the likely cause of the fire, but did not identify the device's brand. The battery and cover had both melted and stuck to the floor of the plane, authorities said.

During the rest of the flight, passengers were forced to endure the smell of burned plastic, burnt electronics and burnt hair in the cabin, the ATSB reported.

"People were coughing and choking the entire way home," the woman said.

The ATSB warning cautioned travellers about the dangers of using battery-powered devices on board and asked passengers with battery-operated devices to stow them properly and keep spares in their carry-on, not checked baggage.

"As the range of products using batteries grows, the potential for in-flight issues increases," the ATSB said. A spokesman for the ATSB declined to specify the brand and model of the headphones or batteries involved in the incident, The Sydney Morning Herald reports.

"The ATSB has assessed that it is the batteries, as the power source, that caught on fire and are therefore the issue," the spokesman said. "All batteries contain stored energy and are therefore potentially risky."

The incident comes after Samsung recalled millions of Galaxy Note 7 phones last year following multiple incidents of the device's batteries exploding or catching fire. The Federal Aviation Administration soon banned the smartphones from being brought onto aeroplanes in October.

Samsung was forced to eventually discontinue the line and recently concluded that the fires were caused by two battery flaws rather than the devices themselves.

Over the past few years, there have also been numerous incidents involving battery-operated devices catching fire or exploding on planes.

In June last year, a passenger's phone got stuck in the reclining mechanism of his seat during a Qantas flight from Los Angeles to New York. While searching for the device, the seat was accidentally moved crushing the device. It soon began hissing and emitting smoke before catching fire.

In August, passengers were forced to disembark from a plane in Sydney after smoke was seen coming from a traveller's hand luggage in the overhead locker. It was later discovered that lithium batteries had ignited.

Melbourne, Jul 24: Home-made cloth face masks may need a minimum of two layers, and preferably three, to prevent the dispersal of viral droplets associated with Covid-19, according to a study.

Researchers, including those from the University of New South Wales in Australia, noted that viral droplets are generated by those infected with the novel coronavirus when they cough, sneeze, or speak.

As face masks have been proven to protect healthy people from inhaling infectious droplets as well as reducing the spread from those who are already infected, several types of material have been suggested for these, but based on little or no evidence of how well they work, the scientists said.

In the current study, published in the journal Thorax, the researchers compared the effectiveness of single and double-layer cloth face coverings with a surgical face mask (Bao Thach) at reducing droplet spread.

They said the single layer covering was made from a folded piece of cotton T shirt and hair ties, and the double layer covering was made using the sew method described by the US Centers for Disease Control and Prevention (CDC).

The scientists used a tailored LED lighting system and a high-speed camera to film the dispersal of airborne droplets produced by a healthy person with no respiratory infection, during speaking, coughing, and sneezing while wearing each type of mask.

Their analysis showed that the surgical face mask was the most effective at reducing airborne droplet dispersal, although even a single layer cloth face covering reduced the droplet spread from speaking.

But the study noted that a double layer covering was better than a single layer in reducing the droplet spread from coughing and sneezing.

According to the researchers, the effectiveness of cloth face masks is dependent on the number of layers of the covering, the type of material used, design, fit as well as the frequency of washing.

Based on their observations, they said a home made cloth mask with at least two layers is preferable to a single layer mask.

"Guidelines on home-made cloth masks should stipulate multiple layers," the scientists said, adding that there is a need for more research to inform safer cloth mask design.

US dictionary Merriam-Webster will update the meaning of the word "racism" after being contacted by a Missouri black woman, who claimed the current definition fell short of including the systematic oppression of people of colour, according to media reports.

"A revision to the entry for racism is now being drafted to be added to the dictionary soon, and we are also planning to revise the entries of other words that are related to racism or have racial connotations," according to a statement of the 189-year-old dictionary shared by Kennedy Mitchum, a recent graduate of Drake University in Iowa, on her Facebook.

Mitchum, 22, emailed the dictionary last month, following the death of African American George Floyd in the custody of four Minneapolis police officers, Xinhua news agency reported.

"I kept having to tell them that definition is not representative of what is actually happening in the world," Mitchum told CNN. "The way that racism occurs in real life is not just prejudice, it's the systemic racism that is happening for a lot of black Americans."

Merriam-Webster's first definition of racism is "a belief that race is the primary determinant of human traits and capacities and that racial differences produce an inherent superiority of a particular race."

"It's not just disliking someone because of their race," Mitchum wrote in a Facebook post on Friday. "This current fight we are in is evidence of that, lives are at stake because of the systems of oppression that go hand-in-hand with racism."
