You are allowed to wash your hands only in designated handwashing sinks. These sinks are specifically intended for handwashing and are equipped with soap and single-use towels or hand-drying devices. Handwashing should not be done in sinks used for food preparation, washing dishes, or disposing of mop water or other waste, as these can contaminate your hands. Bathroom sinks are also considered designated handwashing sinks. In workplaces such as food service, schools, daycares, body art shops, and salons, dedicated handwashing sinks must be available and used exclusively for washing hands to prevent the spread of germs and contamination. It is important to maintain clear access to these sinks and to wash hands thoroughly wherever this designated facility is located. This practice helps prevent the spread of illnesses and maintains hygiene standards.
