It is the latest in a string of high-profile incidents involving titanium rings that have been found to rupture, sometimes fatally. 

In March, a woman who had worked as a tour guide at the New York City Museum was found dead in a carabiners, and a few weeks later, a 23-year-old woman who was travelling in an electric scooter accident in India was killed. 

There have also been incidents in the UK, with a man who had been using the titanium rings of a luxury car to attach a necklace to his throat being shot in the chest in July. 

Titanium rings are used for everything from door hinges to jewellery, from rings on to a watch’s case. 

They are also used to reinforce structural parts of structures, such as bridges. 

But the new reports, by scientists from the University of New South Wales, New Zealand and the University in Cape Town, South Africa, suggest that titanium rings may also have serious health risks. 

The researchers say the risk of titanium rings rupturing can be reduced if they are used properly. 

“The material is not designed for this type of activity, and is more likely to be damaged by vibration and thermal stresses than the use of titanium,” lead author Professor Peter Moulton said. 

Professor Moulons team found that when a titanium ring was placed onto the skin of a person’s neck, the fracture was less severe than if it was placed on a human body. 

Researchers found that if a titanium rings were used on a person with a fracture in the neck, it could be a good thing, because the fracture might prevent further damage to the person’s tissues. 

However, if the ring was used on someone with a normal fracture in their neck, there was no evidence the fracture would stop the fracture from continuing. 

If you break a titanium pipe, it’s not like you can go back to normal – the next day you may not be able to go back in a wheelchair A ring of titanium is made from titanium, an alloy of carbon, carbon monoxide and oxygen.

It is generally used to make tools such as hammers and axes, but titanium pipes can be used for a wide range of uses, from door handles to medical instruments. 

To date, researchers have been able to find two cases of titanium ring rupture. 

One of these occurred in 2009 in India, where a woman in her mid-20s, who was a tourist, was killed by a titanium neck ring on her neck. 

Another happened in 2012 in Japan, where an 18-year old student died after his titanium ring fractured when it was attached to his arm. 

So far, researchers know that there are about a million titanium rings in the world, but it is estimated that only about 10,000 of them are currently used. 

More recently, in 2014, a man in Germany who was visiting Australia had his titanium pipe ruptured and required surgery to repair the damage. 

This happened after the pipe was attached through a titanium earring to a metal plate, and it is not clear what caused the accident. 

Prof Moultons team said that when it came to the safety of titanium, they would like to see a system developed that allows titanium rings to be properly sealed, so that they do not rupture.

“We need to develop a system where the titanium ring has a strong seal and when it ruptures it does not release any harmful chemicals,” he said.

A number of countries have taken steps to ensure that their titanium rings are safely sealed, including the US, Canada, Japan, the UK and South Africa. 

These measures, however, have not been universal. 

For example, a titanium tube in a ring, which is made of titanium and is commonly used for making tools, is usually sealed by the manufacturer, not the customer. 

And it has been reported that the rings of Chinese tourists in the US were damaged when they were placed on their necks.

However, Professor Moulrons team believes that in the future, there will be a greater understanding of the risk and how to minimise it.

“It is not easy to determine how much of the titanium is being released when the material is being used,” he told the BBC. 

It is important that people understand that the use and care of titanium can be a life-long commitment, and there is no one-size-fits-all solution.

“The main goal should be to reduce the risk so that people can enjoy life in their own way, without having to worry about safety,” Professor Moulsons team said.
