Fingernails, nail polish and jewellery
Ensure that fingernails are kept short and clean. Wrist watches and jewellery MUST be removed before surgical hand disinfection Long fingernails, nail polish, and jewellery are impediments to hand hygiene and can promote bacterial growth on hands. Spaces or crevices under artificial or long nails and jewellery are hard to clean, and limit access to those areas. Natural fingernails should be kept short, ideally not extending 0.5 cm (less than 1/4 inch) beyond the fingertips.
