About promotion of disaster prevention measures of existing elevator

 By earthquake centering on North Osaka that occurred on June 18, 2018, enclosure occurred in a large number of elevators.
 We receive falling off cases such as elevators in the Great East Japan Earthquake that occurred in enclosure accident and March, 2011 of elevator which occurred in Northwest Chiba earthquake of July, 2005, and technique standards to modify safely such as elevators establishing in Building Standard Act are revised.
 However, control driving device becomes existing impropriety case (we meet standard at the time of setting, but do not meet current standard.) about things of non-setting by elevator installed before it at door open run protector and earthquake.
 It is said that such an elevator is illegal promptly and is not treated, but I would like aggressive correspondence about setting of control driving device at door open run protector and earthquake that owner or manager ensures the security and prevents outbreak of accident.
