I received this Wordless Wednesday photo from Paul Timm of Allegion, another example of a school district’s efforts to implement a means of locking doors quickly in case of an active shooter situation.  But what about other hazards?  In addition to potential egress problems, how will school staff and emergency responders get in?  And how much force will that chain/hook/eye withstand?  This should not be Plan A.
