No this is not safe because the spring can uncompress more than your bottom arm can move downwards and so even when you have it fully jacked up it will still be under comperssion.
Even with spring compressors it is a nasty job, Ive had a couple come loose (and threw my spring compressors away after the second time) and I know cully has had one come loose too. Only luck alone prevented me or him receiving a serious or fatal injury
They are properly scary when they go the amount of force that is contained within them even when they only have a few turns left till they release is absolutely huge. A spring coming uncompressed and getting loose could comfortably cause a fatal injury and it just isnt worth playing with.
Consider compressed springs to be like playing with a loaded gun where you dont know where the trigger is or how much force is needed to fire it and you have a fair comparison.
Get a garage to do it mate.
