However, a senior manager said the organisation's staff were no more accident-prone than anyone else, despite more than 220 incidents during the 2011-12 year.
The mishaps are detailed in the council's health and safety register, which records all reported safety incidents involving council staff, whether at work or outside the office, each year.
The list has been made public by the council, which published it on its website following an official information request.
The list includes car crashes and other potentially serious incidents and a long list of less significant encounters with everyday objects.
Some were potentially nasty, such as the staff member who was sitting on an office chair when it collapsed, pinning their leg underneath, or staff catching fingers in doors or stumbling down stairs.
Others included a staff member who sprained their ankle ''while taking evasive action'' when confronted by a large dog, and another injured by a wasp that ''came in [the] window while driving and went down [their] shirt''.
Another staff member reported catching a thumb ''on an awkward angle'' while turning over in bed.
Sporting injuries while skiing, tramping, playing tennis and riding bikes also featured prominently. So, too, did holiday mishaps - including a staff member who reported dropping their suitcase on their toe.
Council human resources manager Bruce Miller said the number of incidents recorded was ''pretty typical'' for any given year, and staff were encouraged to report even the most minor incidents, regardless of whether they occurred in the office.
''Some of them you look at and say, well, that was pretty dumb. What did you do that for?
''The policy of the council is if you injure yourself out of work, to the extent that it might affect your ability to do your job, then we ask you to report it.''
The council incurred no cost from the vast majority of incidents, but the information could be used to identify trends and areas of concern needing intervention, he said.
The council had, in the past, organised heavy-lifting demonstrations, arranged driver education training sessions or altered work practices as a result of the information given by staff, he said.
Mr Miller said the council was required to take appropriate steps as a good employer and took health and safety ''pretty seriously''.
It had maintained its tertiary accreditation from the Accident Compensation Corporation - considered the gold standard for workplace safety - after its most recent audit, which kept premiums down, he said.
