Application Fields

During battery assembly tesa® 54485 Fireman Access is applied to the inside of the battery housing. Whilst normal operation it securely seals the fireman access hole against water and dust. In case of fire in the battery pack the hole covering patch reliably shields the passenger compartment from fire and heat of the cells for 5 minutes. During fire in the pack (after 5 minutes) or the vehicle tesa® 54485 opens at high temperatures and ensures easy access for the fireman to flood the battery to safely extinguish it without additional equipment.
