Fire detectors to prevent shack fires wins International Innovation Prize

A student team, featured by GroundUp magazine last year, has won the People’s Choice Award at the Global Social Venture 2014 Competition. Their idea: Khusela, a very low-cost fire detector could reduce the severity of fires in informal settlements. Due to the limited roads, densities, infrastructures (water and electricity) and other services in informal settlements around the world, fires have a serious impact on the livelihoods of shacks in these settlements. If an early detection system could speed up the stopping of fire and let it be contained, millions of lives could be saved every year. It could also allow governments to effectively use the limited resources in these areas.

From the Global Social Venture Competition website: Khusela, has developed a low-cost fire detection device and integrated alert service designed for shack-dwellers worldwide. Our proactive early-warning system networks individuals within communities and with the authorities to mitigate the loss of life and property caused by shack fires – a global human tragedy. There are 1 billion shack/slum-dwellers across the globe that is set to soar to 1.4 billion by 2020. This rate of urbanization will exacerbate the difficult conditions in areas where fire risk is a daily anxiety that has a direct impact on financial security, safety, and well-being. The impact of shack fires has an adverse effect on economies and are, as such, a development challenge that needs to be addressed. The great news about this award is that the Khusela team will be able to start a pilot project in South Africa to see its real-world effectiveness. Combined with fire-retardant paint, fires could become history for many informal settlements. Read more about the Khusela winning the award here.

Below is an article about the real impact fires in shacks have across South African informal settlements. Shack fires are an unremitting scourge facing urban townships. In South Africa, between 2000 and 2010, over 230 000 people were made homeless by fires. Growing urban populations together with inadequate services, in particular electricity and water, means urban shack fires will continue to take their toll. There is an urgent need for effective solutions to address the major causes. by Fergus Tunner of GroundUp

Last year, the City of Cape Town responded to 1,177 fire incidents in informal settlements around Cape Town. According to the City 3,480 shacks were damaged or destroyed and 105 lives lost in 2012 alone.

On New Year’s day (2013), a fire broke out in the BM section of Khayelitsha. More than 4,000 people were left homeless; at least four residents lost their lives.

This incident brought light to a project run by Samuel Ginsberg, an electrical engineering lecturer at the University of Cape Town, to develop a fire detector. Final year engineering student, Francois Petousis, took it on as a thesis project. Petousis wanted to develop a cheap fire detector that could be mass produced.

“Many fires are started by candles, paraffin lighting, and cooking devices. These devices are sometimes left on at night while people are sleeping, and can often be knocked over,” said Petousis.

Shack fires get out of hand because there is no early warning

“People are often not aware of the fire when it begins, and that is when the fire can be fought more easily. What makes this detector a distinctively effective solution is that, when detecting a fire, it emits a low frequency sound that is at a pitch that was recently shown in studies to be most effective at waking people.”

“The sound is distressing and makes the body react. It is an extremely effective alarm.” If a detector goes off in one shack, the pitch is powerful enough to alert neighbouring shack dwellers.

The device is smaller than the palm of the hand and is being called Khusela (meaning “protect” or “defend” in Xhosa). It can be mass produced at a cost of just under R10 per device. The detector, which is durable, can be hung or attached easily from any surface inside a shack and the prototype has a battery life of four years.

“Other fire detection technologies were not suited to a township environment,” said Petousis

Available smoke detecting technologies are designed to be highly sensitive to the slightest presence of smoke. This would be useless in a township environment, which is normally smoky. Other technologies are also more expensive and use removable batteries, which isn’t ideal in a low resourced community. What the Khusela does is sense rapid changes in temperature and then it activates.

A report, prepared by the City of Cape Town, for a Fire Safety Symposium in February corroborates Petousis’ assertion that many fires occur at night when people may be sleeping or unaware. The document reports that most fires are reported between 9pm and 3am.

Other solutions have also been put forward. Working on Fire, a Johannesburg organization, is calling for the use of foam bombs — non-harmful chemical foam that suffocates the oxygen supply to fires and is dropped from the air.

Fire detection by camera has been suggested by the City as another possible strategy

The City Disaster and Management department are focusing on the provision of ‘first strike’ firefighting skills and safety awareness programs.

The department says that fires are mostly accidental, often caused by negligent use of dangerous cooking or heating devices, and as a result of alcohol and substance abuse. Other major causes are illegal electrical connections.

Whereas many solutions emphasize effective fire fighting, the Khusela aims at prevention. The value of this approach was shown in the US, where the introduction of fire detectors for households led to a 50% decrease in home fires after several years.

Petousis hopes to provide fire detectors for most informal settlements in and around Cape Town, and later countrywide.

“We are in the process of finding the best means to distribute them, but the biggest challenge is to find funding for the mass production of these detectors,” he said. “This project is non-profit, but we need funding to pay for the production and distribution. If we get funding we may operate as an NPO, otherwise a contract from a government department could allow us to take this project out to settlements. Getting the Khusela out to people is our chief priority at this stage”.

Shack fires present a very real threat to residents of informal settlements and any measures to prevent them should be taken seriously.

    Most accidental candle fires like these can be prevented!

    Kevin’s Kandles provide an innovative concept in safer candles for illumination. These candles are Much Safer than traditional candles, Convenient, Inexpensive and Environmentally Friendly.

    If a Kevin’s Kandle is left unattended – it will go out; if it is tipped over – it will go out!

    Ideal for Poverty Relief. Less than 15₵ per 10 hour candle.
