Make the locking of school toilets during class time illegal.

Finding an appropriate member of staff with a key is a time-consuming process and isn't fast. Therefore under 'The Workplace (Health, Safety and Welfare) Regulations 1992' - Regulation 21 #188 - 'Sufficient toilet and washing facilities should be provided to allow everyone at work to use them without unreasonable delay.' [http://www.hse.gov.uk/pUbns/priced/l24.pdf] and Regulation 21 #190 in the same Act, 'Facilities should be located so they are convenient...' I believe locking school toilets fails to meet the criteria and these same rights should be applied to students. Having to find a member of staff, without knowing where they would be, takes time and I, with many others, argue that it is an 'unreasonable delay'!
