The building, which has a staff capacity of 1,150 people, was completely evacuated by around 5.30pm.
It is understood that a number of staff members had been complaining about headaches and feeling ill throughout the day.
One said online: ”I was in the office today but left just before it was evacuated (and went home as I felt dodgy and vision was blurry, funnily enough!)"
The Scottish Fire and Rescue Service said at around 8.30pm that crews with breathing apparatus had left the building and said tests revealed that the atmosphere was at a "safe level" but further inspections would still be carried out.
Police Scotland said: "We received a report of a possible chemical incident within a Scottish Gas building in Waterfront Avenue, Edinburgh, around 5.15pm today.
"We are working alongside our partners in the Scottish Fire and Rescue Service to establish the cause of this incident."
Scottish Gas parent company Centrica were unable to comment on Friday night.

Why are you making commenting on The Herald only available to subscribers?
It should have been a safe space for informed debate, somewhere for readers to discuss issues around the biggest stories of the day, but all too often the below the line comments on most websites have become bogged down by off-topic discussions and abuse.
heraldscotland.com is tackling this problem by allowing only subscribers to comment.
We are doing this to improve the experience for our loyal readers and we believe it will reduce the ability of trolls and troublemakers, who occasionally find their way onto our site, to abuse our journalists and readers. We also hope it will help the comments section fulfil its promise as a part of Scotland's conversation with itself.
We are lucky at The Herald. We are read by an informed, educated readership who can add their knowledge and insights to our stories.
That is invaluable.
We are making the subscriber-only change to support our valued readers, who tell us they don't want the site cluttered up with irrelevant comments, untruths and abuse.
In the past, the journalist’s job was to collect and distribute information to the audience. Technology means that readers can shape a discussion. We look forward to hearing from you on heraldscotland.com
