London Fire Brigade was worried the release of the raunchy film a day before Valentine’s Day could lead to kinky couples getting trapped in objects such as handcuffs or rings as they recreate steamy scenes.
The service launched a Twitter campaign, Fifty Shades Of Red, warning lovers to stay safe in the bedroom — and mind the keys to the handcuffs.
It revealed it has seen a surge in people getting stuck in compromising situations since EL James’ erotic novel was released in 2011.
In November, firefighters were called by doctors at King’s College Hospital and used hydraulic cutters to remove two penis rings stuck on a man for three days.
Crews were also called to help a man whose manhood was stuck in a toaster, while another trapped his in a vacuum cleaner.
But a brigade spokeswoman said they had not been called out to an incident over the weekend. “We are really pleased people have taken our advice, are being safe, keeping the keys handy and not getting into embarrassing situations.”
DIY store B&Q warned its staff to prepare for a rush on cable ties, rope and tape.
