Significance and Use4.1 Accessibility design standards require water suppliesand drain pipes under lavatories and sink are to be insulated orotherwise configured to protect people with disabilities fromcontact with exposed pipes. No sharp or abrasive surfaces areallowed under lavat
20、ories or sinks.4.2 People in wheelchairs and people with physical disabili-ties are part of the most at risk group for scalding, severereaction, bruising and cuts from exposed piping under lavato-ries and sinks. These groups, which also include youngchildren, the elderly, and the infirm sometimes re
21、quire differentsafety regulation due to but not limited to slower reaction time,physical disabilities, mobility impairments; and medical con-ditions which can increase exposure contact time and increasedvulnerability to severe reaction, discomfort, burns, bruises,abrasions, and cuts of the skin.4.3
