I have essential workers who do home visits. How do I assess the risks?

The fundamentals of risk assessment remain the same as for any other foreseeable risk.

Focus on risk controls which reflect Government guidance; social distancing (2 metres) and avoiding contact with occupiers if possible, high-quality PPE – disposable overalls, gloves and fluid repellent surgical face masks, ready access to antibacterial wipes for surfaces, tools and equipment and plentiful hand sanitizer.
