As of December  1, 2011, passenger elevators in Texas must meet the safety standard requirements set out in Chapter 754 of the Health and Safety Code. Any passenger elevator without door restrictors or found to have non-working door restrictors after December 1 will immediately be removed from service. The elevator will not be placed back into service until it is inspected and all required safety features are verified by a registered elevator inspector.
