The World Health Organization (WHO) has published a booklet entitled “Getting your workforce ready for Covid-19”. The eight-page document is organized by topics and in one of them, it is possible to read as follows:

Promote regular and thorough hand-washing by employees, contractors and customers:

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.
