28. Hand wash basins can cause similar or even greater queuing than for WCs, especially for female toilets.
29. In mains connected toilet facilities it is advisable to provide one hand wash basin per two toilets for females, one hand wash per four toilets for males.
30. For single plastic toilet installations hand-washing facilities should be provided in the ratio of one hand wash basin per five facilities (WCs & Urinals) for females with not less than one hand-washing facility per ten toilets provided for men.
31. Consideration should be given to providing lower height wash basins where wheelchair users and/or a significant number of children are expected to attend an event and hand operated rather than foot operated pumps for wheelchair users.
32. Preference should always be given to providing warm-water hand-washing facilities and adequate supplies of suitable soap as this is the most effective means for cleaning hands.
33. Antiseptic hand wipes or bactericidal soap/gel can be provided, however organisers should be aware that these wipes may only be effective when hands are not visibly contaminated (for example, by mud).
34. Hand-washing facilities alone may not be adequate for events longer than one day, or when overnight camping is available. In these instances, consider whether to provide shower facilities, if an adequate supply of fresh water and sufficient water pressure is available.
35. In some instances, it may be appropriate to provide hand washing and/or showers even if the event is short in duration.
36. Alcohol and other gels and wipes must not be used where there is a risk of contamination by E. coli 0157. Thorough washing, ideally with hot and cold (or mixed warm) water and a good quality anti-bacterial soap, is required.
37. Anti-scald safeguards should be in place when children are using wash facilities.
