PAUL MÜLLER HAVARIEBOX GEN2 – Compact protection for defective small lithium devices

Numerous mobile devices with lithium energy storage systems are used every day in fire stations, industrial plants and public institutions. If batteries become conspicuous or damaged, a fire hazard can quickly arise. The Havariebox Gen2 from PAUL MÜLLER offers a compact solution for the safe storage and transport of such small devices – such as smartphones, rechargeable lights or notebooks.

The lockable lid limits the spread of fire to the interior of the box. At the same time, the defined venting opening in the lid with integrated filter medium massively minimises the escape of smoke and venting gases. This allows a damaged energy storage device to react in a controlled manner without the danger spreading to the outside.

Technical features and dimensions

The box measures 600 mm in length, 400 mm in width and 400 mm in height on the outside. The interior has a length of approximately 530 mm, a width of 330 mm and a height of 335 mm, which corresponds to a volume of approximately 58.6 litres. Without extinguishing agent, it weighs approximately 23.5 kg. The steel box is powder-coated in RAL 3020 (signal red) and has a thermally insulating inner lining.

Safe pressure relief and UN approval

The Gen2 emergency box is equipped with a defined pressure relief system via the filter medium in the lid, which enables controlled extraction of excess pressure, smoke and gases. The box has UN approval for safe transport. The box can be used for lithium batteries up to 1,000 Wh and is provided with appropriate labelling, including the UN approval number and the stickers "Battery emergency" and "Emergency box". Recommendations for use are also provided on the box.

Versatile use in firefighting, industry and administration

The compact design allows it to be loaded onto emergency vehicles or stored in a space-saving manner in the equipment shed. In industrial companies, the boxes are kept at defined locations or brought to the scene of the emergency by factory fire brigades as needed. The emergency boxes are also established in administrative buildings and public institutions as an effective immediate measure in the event of lithium emergencies.

Extover extinguishing granulate for increased safety

The box can be equipped with 2 x 2.7 kg bags of Extover dry extinguishing agent. This special extinguishing agent made of expanded glass granulate is non-flammable, reusable (if no fire has broken out), recyclable and environmentally friendly. It displaces oxygen, binds gases and vapours, and thus supports safe firefighting and disposal. Two 2.7 kg bags are included in the price!

Robust and durable construction

The steel container with powder-coated surface and thermally insulated inner lining guarantees resistant and durable usability for daily requirements in various areas of application.

FAQ

That depends on various factors that need to be considered:

  • size of the battery(ies)
  • condition (e.g. non-critical, defective, critically defective or prototype)
  • power

Transport boxes are available in many different sizes and specifications. The packaging group for which the box is suitable is indicated for each product.

Even if the batteries are not critical, remember to protect them from shocks and to order appropriate filling material if it is not already included in the box.

Yes. Should a battery reach a critical state and cause a fire, separating the batteries will prevent the fire from spreading and multiplying.

Generally, the insulation and protection material should line all sides of the container. The batteries are stored between individual layers.

We also have containers in our program that already have the protective material integrated into the outer wall. No further protective layer is necessary here.

The technical principles for storage and transportation solutions are very similar. The transport boxes are also subjected to extensive tests in accordance with ADR (drop test, fire test, etc.) to confirm compliance with the ADR regulations. The packaging regulations are extensive and regulated by law.
There are currently no comparable regulations for storage. Nevertheless, manufacturers of storage boxes regularly carry out appropriate tests.
The right container depends on the type and size of the battery to be shipped or stored.

The transportation of batteries is subject to ADR regulations.

The number, size and weight, energy density and condition of the batteries are crucial parameters for finding a suitable transport container for lithium-ion batteries. The selection process is complex and should be carried out by appropriately trained personnel. We have a trained hazardous materials officer on our team. Please feel free to contact us.

Plastic containers are cheaper but not as durable as metal containers. They are suitable, for example, for non-critical batteries, defective batteries, prototypes and end-of-life batteries. They can be used for both storage and transportation.

Metal containers are required, for example, when dealing with critically defective batteries.

The exact packaging instructions for these cases can be found in the ADR or by consulting a certified hazardous materials specialist.

To date, there are no legal requirements for the storage of lithium-ion batteries, which does not mean that they should be stored without suitable protective measures.

It is best to check with your insurer to find out which measures they recognize as suitable in the event of a claim.

For example, a suitable box could already be recognized as spatial separation.
