a. Put sanitizing hand rub dispensers in prominent places around the workplace;
b. Make sure these dispensers are regularly refilled;
c. Display posters promoting hand-washing – ask your local public health authority for these or look on www.WHO.int;
d. Combine this with other communication measures such as offering guidance from occupational health and safety officers, briefings at meetings and information on the intranet to promote hand-washing;
e. Make sure that staff, contractors and customers have access to places where they can wash their hands with soap and water;
f. Why? Because washing kills the virus on your hands and prevents the spread of Covid-19.
