follow public health advice including washing and drying hands well before and after any contact with customers
ensure surfaces that are frequently touched – such as desks, countertops, tools, electronics, and doorknobs – are cleaned thoroughly and often
minimise the risks of exposure to COVID-19 by suggesting to your customers they let you know if they are unwell with a cough, fever, or shortness of breath and rescheduling work as needed
apply physical distancing principles at work and minimise face-to-face contact with customers wherever possible. For example, a builder could give their client a call to tell them about any progress, instead of meeting them in person
develop a plan for rescheduling work if customers have to self-isolate or become unwell
reach out to business groups or industry organisations to share information and connect with others in similar situations.
