To best assess the impact on business operations, Florida businesses should consider carefully reviewing the order, and any prior orders or documents referenced within the order and modify their business operations accordingly. Key provisions of the order are summarized below to aid in such business assessments. To the extent a local official action or order is less restrictive, the Governor's Order prevails, but local governments can still impose restrictions that go beyond the state-wide mandate. Accordingly, in conducting their assessments, businesses should also consider restrictions imposed by local government jurisdictions to which they are subject.

The order defines "essential services" as the list identified in the Department of Homeland Security's Cybersecurity and Infrastructure Security Agency's (CISA) Guidance on the Essential Critical Infrastructure Workforce, dated March 28, 2020, or as subsequently amended. The CISA Guidance provides broad listings of critical services within the following critical sectors:

1. Health Care/Public Health
   Examples include health care providers and caregivers, including physicians, dentists, psychologists, nurses and assistants, infection control and quality assurance personnel, pharmacists, physical and occupational therapists, social workers, optometrists, speech pathologists, chiropractors, diagnostic and therapeutic technicians and technologists, hospital and laboratory services, and medical supply manufacturing.

The order also makes reference to other essential services and activities listed in the Governor's earlier Executive Order 20-89, incorporating a list of such services and activities identified by Miami-Dade County, which includes:

1. Contractors and other tradesmen, appliance repair personnel and exterminators;
2. Private colleges and trade schools, but only as needed to facilitate online or distance learning;
3. Home-based care for seniors, adults or children; and
4. Professional services, including legal or accounting services, when necessary to assist in compliance with legally mandated activities.

In addition to conducting an assessment on whether their services are considered essential services, those Florida businesses that determine they meet the above criteria will also have to identify, assess and implement any public safety modifications to business activities, such as social distancing and handwashing measures, in accordance with earlier executive orders in Florida. To the extent a local official action or order is less restrictive, the Governor's order prevails, but local governments can still impose restrictions that go beyond the state-wide mandate. Accordingly, in conducting their assessments, businesses should also consider restrictions imposed by local government jurisdictions to which they are subject.
