Celebrity SAS: Who Dares Wins stars line up for the new show before being gassed on their first day.
They faced a mock chemical weapons attack to experience the effects of CS gas as part of the new series of the celebrity edition of the popular Channel 4 show.
EastEnders alum Maisie Smith branded it "hideous". She further commented about it: "I couldn't breathe with the mask on. Part of me was saying, 'Am I actually dying?'."
