Doors and barriers from PS DOORS keep workers, facilities and the environment safe from spills. The PS DOORS Bottom Hinge Barrier is automatically triggered by a spill and quickly pivots up to protect facilities (it can be deployed passively, electronically or manually). It is self-stored and always in place. It can even be connected to an existing alarm system. Because the door is self-stored within a floor surface, it allows personnel or vehicles to use the opening while the barrier is not deployed.
