Why are Spelsberg's enclosures made from halogen-free materials?

Short answer

We use halogen-free materials across our core products because halogens — fluorine, chlorine, bromine, iodine and astatine — release toxic gases when exposed to fire. Excluding them significantly reduces the emission of toxic gas and smoke in a fire, which helps maintain air quality, supports safer evacuation and prevents corrosive gases from damaging electronic components or compromising structural integrity. This matters most in public areas, rescue routes and other regulated spaces, and it allows us to meet safety standards such as DIN VDE 0100-718. Halogen-free materials are used across the majority of our range, and especially in our Lifeline enclosures, which meet DIN 4102 part 12 and are certified in accordance with VDE and ULEU for up to 90 minutes of protection during a fire.

Our enclosures are halogen-free because halogens release toxic gases when exposed to fire. Safety and environmental responsibility are paramount at Spelsberg, so we use halogen-free materials for all our core products, excluding fluorine, chlorine, bromine, iodine and astatine. This allows us to adhere to rigorous safety standards such as DIN VDE 0100-718, and to make sure our products provide the utmost in protection and reliability.

Using halogen-free materials significantly reduces the emission of toxic gases and smoke in the event of a fire. That is especially important in products designed for use in public areas, rescue routes and other regulated spaces, where maintaining air quality and allowing a safe evacuation are critical. It also minimises health risks to individuals and prevents the release of corrosive gases that could damage electronic components or compromise structural integrity.

Halogen-free materials can be found within the majority of our product line-up, and especially in our Lifeline range of enclosures: https://www.spelsberg.com/geos-industrial-and-outdoor-enclosures/lifeline/. We designed the Lifeline series to meet the highest standards of protection and durability, including DIN 4102 part 12, with certification in accordance with VDE and ULEU, providing up to 90 minutes of protection during a fire.
