Facilities providing mental health treatment are often equipped with seclusion rooms for behavior intervention. Most of these
patients are generally not a significant danger to themselves or others.
(d) Any seclusion
room should be equipped with a door that locks only if the lock is equipped with a device that automatically disengages the lock in
case of an emergency, such as a fire or tornatic weather.
seismic zones 3 & 4, ESS submits that earthquakes should be included in the list of applicable emergencies and propose an
automatic earthquake door release criteria corresponding to strong motion events exceeding the lower ASCE 25 response curve.
Although the ASCE 25 standard was developed for residential earthquake actuated automatic gas shutoff, the lower curve provides
a reasonable 'first level' of shaking at which safety concerns arise. The ASCE 25 standard also has the 'feature' of rejecting
high frequency / high acceleration energy which might be associated with building mechanical equipment.
