Seismic events cause standard stair connections to fail — occupants cannot exit and first responders cannot enter, creating a high risk for occupant injury or death. But now, DriftReady Stairs are engineered to withstand interstory drift, reducing the transfer of damaging force beyond the industry standard of 2.5%, up to 4%. This game-changing system ensures safe egress and ingress during and after an earthquake. Constructed with resilience in mind, DriftReady Stairs aid in rescue efforts beyond an earthquake event. It has been rigorously tested under earthquake simulation to save lives.
