Marshals are out and about across Hertsmere offering support to help keep residents, visitors and businesses safe.
Wearing hi-vis jackets, the marshals' role is to remind people of the importance of social distancing, wearing face-coverings and regularly washing their hands.
They will also advise local businesses on queue management and on one-way systems.
It comes as Hertsmere experiences its highest number of Covid cases ever, with a lack of testing available in the spring, with more than 2,000 cases recorded since December 20, according to government figures.
Borehamwood, Radlett, and Bushey are among areas in the borough with the highest levels of cases.
