The use of very hot light sources at any kind of event always involves the risk of fire. As early as 1879 there was a "local police regulation on fire police in theatres", because fires developed again and again.

Nowadays, the flame retardancy of textiles used is regulated in current building law or in the Ordinance on Places of Assembly.

Flame retardation is required according to DIN4102 or EN 13501.

Flame retardant, digitally printable FR materials from IBENA DPI-TEX include the following:

• Voile 55 IFR (article 8900)
• Nonwoven 120 FR (article 9856)
• Nonwoven Carpet FR (article 9862)
• CS Zeltnessel 150 IFR (article 8918)
• Glas 220 (article 8513)
