Devices have been recalled due to fire risk in recent years

Business interruption is the greatest risk for companies (caused, among other things, by fires)

Around every third fire is caused by electricity, many from electrical appliances. Quality-conscious manufacturers have been bringing safe products to market for years. The causes, which can lead to a technical defect, and possibly fire, can never be completely eliminated.
Common causes of fire:

  • Plug connections
  • Voltage fluctuations in the power grid
  • Component failure
  • Operation out of specification
  • Aging
  • Environmental conditions
  • Cold solder joints
  • Manufacturing fault

Since many fires occur in electrical devices, it makes sense to extinguish the fire as early as possible, and directly at the place of origin, when the fire is still small. Existing fire protection concepts are good, however they usually only extinguish a fire when it has already spread beyond the device.

A sprinkler system in one room is the best way to prevent a fire from spreading to other rooms, or the entire building, by keeping the fire small and often manage to extinguish it. Device-integrated fire protection implements the concept of a sprinkler system for electrical devices directly at the source of a fire - in the device.

The fire is detected at its origin, the fire is automatically extinguished, the power is permanently interrupted (to prevent re-ignition), and a notification is sent.

This prevents significant consequential fire damage and reduces the risk of business interruptions.

What is the E-Bulb?

The E-Bulb is a fire-extinguishing fuse. The smallest version is just two centimetres tall, as small as a typical micro fuse. This makes the E-Bulb the smallest fire extinguisher in the world.

The E-Bulb can be built into the electronics by manufacturers and protects electronic equipment from damage, when it might otherwise be too late. If an electrical device develops a technical fault, the E-Bulb can detect the fire, extinguish it, and prevent it from reigniting.

The E-Bulb is a new, innovative component, supporting quality-conscious manufacturers to make safe electrical devices even safer.

The areas of application for E-Bulbs are many and varied. They range from power adapters in advertising screens (media technology), to ventilators in medical technology, and household appliances in homes.

Comparable to the aqua-stop leak protection in washing machines, the E-Bulb is part of the fire-stop system for electrical appliances.

The E-Bulb can easily be installed in the electronics, protecting your electrical devices around the clock (24/7), even without power and in standby mode.

The E-Bulb was developed based on sprinkler glass technology, which has been tried and tested billions of times, and consists of a coated glass bulb filled with non-toxic extinguishing agents.

How can the investment be earned back?

An innovation that protects and saves costs

Reduce product recall costs

Example:
Every major household appliance manufacturer has had to recall ranges of appliances in recent years, due to the risk of fire. The use of E-Bulbs reduce product recall costs. Sometimes the need to recall the entire range can be avoided, as in the event of a fire the E-Bulb extinguishes the fire and cuts off the power supply to the device. There is then a straightforward service need for individual defective devices. If a recall should nevertheless be necessary, the otherwise significant reputational damage is significantly lowered due to the installation of E-Bulbs, as "precautions were taken".

Example Calculation:
200,000 Recall Units x $50 Recall Costs = $10m Costs + Significant Reputational Damage

vs. Material Costs x Production Quantity = Positive Business Case

Cost reduction

Different fire protection concepts can be used in the design of electronics. Our aim is to increase safety. The use of E-Bulbs can reduce the overall product costs, for example by reducing or replacing flame-retardant materials. Furthermore, these flame-retardant materials are often criticised for being harmful to the environment.

Easy building approval

Through the use of device-integrated fire protection, including E-Bulbs, electrical appliances, such as digital signage and LED advertising screens, switch from being classified as “causing a fire” to “being involved in a fire” in a fire risk assessment. This is especially relevant for sensitive locations, such as shopping centres, exhibition halls, airports, or train stations. This also means that printers, screens or billboards can often gain installation approval, even in escape route areas.

Business interruption
protection

The use of E-Bulbs can protect against business interruptions, or shorten the interruption time. Every third fire in Germany causes over €500,000 of property damage in industry, so much that the companies concerned can no longer recover. Only 23% of all firms affected by a fire completely reopen their business again. While more than 40% of companies have to stop trading all together after a fire (see “Logistik heute”).

  • Hospital: In England there are over 550 fires in hospitals every year, statistically that’s 1.5 per day. Often the origin of these fires lies in electrical equipment. Medical technology devices with built-in E-Bulbs reduce the risk of fire, and thus increase safety for patients and protect against commercial and asset loss, and interruptions to healthcare services.
  • Hotel: Consider a fire breaks out in a hotel minibar. Without fire protection integrated into the device, only the sprinkler system protects the hotel so that it can continue to operate. The room is usually locked down for a few days and cannot be booked, leading to a loss of income. In the event of a fire an E-Bulb in the minibar would allow the refrigerator to be replaced quickly, the guests would be unaware, and normal operations could continue. This combination of sprinkler system and device-integrated fire protection therefore makes sense.
  • Industry: The cost of business interruptions in industry is rapidly increasing into the millions. Securing production-relevant systems, by installing E-Bulbs as secondary protection within power supplies, both pays off and makes economic sense.

Accepted by
insurers

The operation of electrical devices with device-integrated fire protection (e.g. E-Bulb) is accepted by insurance companies. For manufacturers it concerns product liability and recall cost insurance, and for operators it is relevant for fire and business interruption insurance. Its use makes it easier to take out general insurance, and for many insurance companies the use of integrated fire protection solutions is even relevant to premiums. Please speak to your insurance company.

Integrated fire-stop
as a unique selling point

  • Safety as a product characteristic is valued by customers and, as a unique selling point, can secure market shares, and help to win orders.
  • The E-Bulb can help to market to consumers the added value of a device-integrated fire-stop, as a built-in fire extinguisher.

Would customers spend more money on devices
with an integrated fire-stop?

Yes! E-Bulb is a safety feature that can be marketed.

Where is the E-Bulb already state-of-the-art?

Selected case studies

Case Study Media Technology

Wherever people gather in large numbers, fire protection plays an important role. This applies in particular to Frankfurt Airport, Germany’s largest and most frequented airport, with almost 200,000 passengers a day (2019), and over 81,000 employees. Given this, the safety requirements for all types of technical infrastructure are high. Thanks to an invention by Job GmbH, electronics company Samsung [article link] has received approval to install large format LED media screens in the airport. Due to the integration of E-Bulbs into the LED media screens, among other measures, the screens have changed from being considered the potential ‚cause of the fire‘ to being ‚involved in the fire‘ from the point of view of fire protection experts, allowing them to be used in more fire-sensitive locations.

Case Study Medical Technology

Statistically, a fire breaks out in a German hospital every week, and electrical devices are often the source of these fires. In recent months, the need for ventilators has increased worldwide, due to the coronavirus pandemic. Tragically, several patients died in St. Petersburg and Moscow in May 2020 due to fires caused by respiratory equipment. Device-integrated fire protection can be installed in the majority of medical devices at limited cost. The world's smallest fire extinguishers, known as E-Bulbs, are often a good choice. Increasingly, medical technology companies are opting for device-integrated fire protection to make their products even safer.

Case Study Home Appliances

Refrigerators, dishwashers, televisions ... most people have many electrical appliances at home, and not just since the smart-home trend emerged. However, since then the fire risk has increased, as most electrical devices now run permanently in standby mode, constantly drawing electricity, so they can be controlled remotely. Every electrical device which remains ‚on‘ is a potential fire hazard. Fortunately, the vast majority of electrical household appliances are safe, however the reasons why a fire can start are so varied, that a fire risk can never be completely ruled out. Knowing their home appliance has a built-in mini fire extinguisher to minimize the fire risk, allows many people to sleep a little sounder.

Electronics

Case Study_Elektronik

The scope of application for E-Bulbs is broad. Here are a few practical examples:

  • Power supply units & control devices: E-Bulbs are already installed in electrical power devices, as an additional protective measure, to protect against consequential fire damage, in the event of technical defects, and to minimize business interruptions.
  • Lighting: E-Bulbs are installed in industrial warehouse lighting to minimize, as far as possible, the inherent risk of fire from the LED modules, drivers and plug contacts.
  • Solar Panel Systems: For safe power interruption and prevention of larger fires on the carrier systems.
  • Automotive: E-Mobility calls for new fire protection concepts. The E-Bulb provides reliable and irreversible power interruption before a possible “thermal runaway” in the vehicle, and in the charging station electronics.
