"Prison officers do not have a 'duty of care' to protect prisoners who harm themselves while taking part in illegal behaviour. With regard to needles in prisons, provision of bleach could also be harmful. Bleach is by nature a corrosive agent and could cause serious injury if thrown into the eyes of a prison officer or fellow prisoner, There is evidence that even the highly caustic phenol used to sterilise dental instruments does not eliminate all HIV viruses - only autoclaving in super-heated steam is fully effective. If government provided bleach fails to sterilise prisoners’ illegal needles adequately, does the government become liable for breach of duty of care?"
