Several accidents occurred which threatened the station's safety, such as the glancing collision between ''[[Kristall]]'' and [[Soyuz TM-17]] during proximity operations in January 1994. The three most alarming incidents occurred during [[Mir EO-23|EO-23]]. The first was on 23 February 1997 during the handover period from [[Mir EO-22|EO-22]] to EO-23, when a malfunction occurred in the backup [[Vika oxygen generator|''Vika'']] system, a [[chemical oxygen generator]] later known as solid-fuel oxygen generator (SFOG). The ''Vika'' malfunction led to a fire which burned for around 90 seconds (according to official sources at the TsUP; astronaut [[Jerry M. Linenger|Jerry Linenger]] insists the fire burned for around 14 minutes), and produced large amounts of toxic smoke that filled the station for around 45 minutes. This forced the crew to don respirators, but some of the respirator masks initially worn were broken. Some of the [[fire extinguisher]]s mounted on the walls of the newer modules were immovable.<ref name="Dragonfly"/>{{page needed|date=February 2021}}<ref name="OffPlanet"/>{{page needed|date=February 2021}}

The other two accidents concerned testing of the station's [[TORU]] manual docking system to manually dock [[Progress M-33]] and [[Progress M-34]]. The tests were to gauge the performance of long-distance docking and the feasibility of removal of the expensive [[Kurs (docking system)|''Kurs'']] automatic docking system from Progress spacecraft. Due to malfunctioning equipment, both tests failed, with Progress M-33 narrowly missing the station and Progress M-34 striking ''[[Spektr]]'' and puncturing the module, causing the station to depressurise and leading to ''Spektr'' being permanently sealed off. This in turn led to a power crisis aboard ''Mir'' as the module's solar arrays produced a large proportion of the station's electrical supply, causing the station to power down and begin to drift, requiring weeks of work to rectify before work could continue as normal.<ref name="SSSM"/><ref name="Dragonfly"/>{{page needed|date=February 2021}}
