What washing facilities should be present on a site where biological hazards might be found?

All sites must have adequate welfare and washing facilities, regardless of whether biological hazards are present. This is a requirement of the law. The washing facilities must include an adequately sized sink i.e. large enough to wash the hands, face and forearms. Hot and cold (or warm) preferably running water, soap (or other cleaning products) and towels (or other means of drying) must also be provided. In some circumstances, additional facilities may be needed. For example, when dealing with sewage, nail brushes and disposable paper towels should be provided in addition to the usual facilities. If heavy contamination is foreseeable, showers will also be appropriate.
